Overview of construction waste management in Germany
Construction and demolition (C&D) waste management in Germany is a mature and well integrated sub industry within the broader German construction market. In 2002, German construction and demolition activity generated 214 Megatonnes of waste composed two thirds of excavation material, nearly another third of building and road demolition waste and a smaller fraction of mixed construction site waste. Despite these high numbers, only 15% of this material was disposed of in landfills, while the remaining 85% was recovered and reused in further applications or recycled. Germany’s high material, energy and labour and waste disposal costs favour the economics of recovering, reusing and recycling as much C&D waste as possible. Additionally, strong waste management systems have been long required by laws and regulations at all levels of government in order to minimise the impact of C&D waste in the waste stream. More recent versions of these regulations focus on the complete material cycle, working towards a closed loop substance cycle in construction and demolition, known as “Kreislaufwirtschaft”. This combination of regulatory pushes from government and economic pulls from the market have helped Germany establish an effective C&D waste management infrastructure. Furthermore, waste management and abatement practices have been integrated into mainstream architectural and engineering education and practice. Architects and engineers designing and constructing buildings are obliged to consider the entire life cycle of materials, from production, to removal and reuse or recycling, of components they install in buildings. There is however room for improvement, specifically in increasing the proportion of material uptake directly by the construction industry, improving demolition and material processing techniques and developing higher value applications of for higher value recovered C&D materials, such as concrete and brick, and diverting them from lower value applications such as soil stabiliser.

1.1
Institutional Framework
The Federal German Republic is composed of 16 states (Laender) with relatively broad powers and responsibilities over their regions. Three Laender (Bayern, Sachsen and Thueringen) are considered Freistaaten (Free States) and posess somewhat more autonomy than their counterparts. Another three Laender (Berlin, Hamburg, Bremen) are city-states and combine the identities and responsibilities of a state and a muinicipality. Generally, the Federal level of government establishes laws that the Laendner must implement and administer. In Germany, the primary responsibility for ensuring the proper treatment of C&D waste is in the hands of local authorities. Meanwhile, the Laender, are responsible for the implementation and enforcement of regulations meant to achieve C&D waste goals set by higher levels of government, particularly the Federal government of Germany and the EU. At the EU level, regulation of Construction and Demolition Waste falls under the broader category of waste and is integrated into the broader targets set by legislation in this area of concern. Member states were obligated to adopt the original waste Directive of 1975 and all further amendments to the law. The Sixth Environment Action Programme 2010 is the most recent of EU initiatives to improve implementation of EU legislation in member states and is overseen by the European Commission with the European Environment Agency as a supporting institution. The European Commission itself is responsible for ensuring the compliance of member states with EU legislation. At the national level, Germany’s Ministry of the Environment, Nature Conservation and Nuclear Safety, supported by the Federal Environmental Agency, is responsible for the development of legislation on C&D waste. The national level of responsibility includes the provision of technical instructions regarding the disposal of wastes, the setting of targets and goals and transposition of EU Directives. All federal level legislation overrides regional and local legislation when conflicts arise. At the state level, “Laender” are responsible for the implementation of federal legislation and establishing more specific extensions waste management legislation. They are responsible for the enforcement of regulations on C&D waste and overseeing the proper operation of waste treatment and disposal facilities. At the local level, municipalities are responsible for the administration and issuing of demolition and construction permits that now occasionally include detailed deconstruction plans and detailed recycling specifications of the building’s materials. While local authorities are responsible for arranging the collection, recycling and disposal infrastructure of household waste, commercial waste such as C&D waste is solely the responsibility of the waste’s owners. The local authority ensures this responsibility is met according to federal and state legislation and is responsible for initiating prosecution against offenders. Any commercial use of the processing, recycling and disposal infrastructure operated by the municipality is paid for directly by the user.

Regulatory Framework
The disposal of waste is regulated by a multiplicity of laws and regulations as well as technical regulations on both the European and national levels. Germany’s first law on waste disposal was enacted in 1972, establishing a change from rubbish tips (most of them unregulated and uncontrolled) to centralised, controlled and regulated landfills. In 1986 the law for the prevention and disposal of waste was enacted. It outlined for first time the principles for the transition from disposal to waste management. According to this law, the first goal must be the prevention of waste and if prevention is not possible, the composition of waste must be improved in order to permit reuse or recycling. Generated in 1993, the Technical Instruction for Municipal Waste (DAVA, 1993), based on the former Law on Prevention and Disposal of Waste of 1986, specifies the treatment and disposal of waste and deals with waste streams such as domestic waste and building and demolition waste. The goals of this order are to recycle unavoidable waste, to reduce the toxicity of waste and to ensure that an environment friendly treatment or disposal of waste is maintained. It describes that construction and demolition waste should be collected and prepared for recovery separately at the place of arising. The responsible municipalities should encourage the utilisation of mobile or semi-mobile recovery installations. It also contains requirements concerning the disposal of waste. Fractions which do not meet the requirements set out in the Technical Instruction for Municipal Waste will not be allowed to be landfilled and will have to be treated further. In October 1996, the Recycling and Waste Management Act was enacted (Gesetz, 1994). This law set principles for the development of waste management towards a closed loop economy. It established a new hierarchy for waste treatment where the avoidance of waste is better than the recycling of waste, but recycling is more preferable to the disposal of waste. The disposal of waste is only permitted when recycling is much more expensive or impossible and the waste is unavoidable. This Act established also the responsibility of the producers for the waste arising from their products. In order to comply with the objectives of the Act, waste destined for recovery is to be kept and treated separately. Recovery of waste has priority over disposal to the extent that recovery is technically possible and economically reasonable (Art. 5 Krw-/AbfG). Art. 7, 23 and 24 KrW-/AbfG authorises the federal government to enact administrative orders and statutory ordinances, with the aim of enforcing prevention, recovery and to reduce contamination on wastes. The Recycling and Waste Management Act contains supplementary subsidiary regulations, which consist of various ordinances and are shown in table 1.
Table 1: Supplementary regulations of the Recycling and Waste Management Act of
5 - 27.10.2006
1996 Source: Schultmann (2001) Ordinances that restructure supervision under waste management law and align it with EU law • Ordinance on the Classification of Waste Requiring Special Supervision (Verordnung, 1996a) • Ordinance on the Classification of Waste for Recovery that Requires Supervision (Verordnung, 1996b) • Ordinance on the Furnishing or Proof (Verordnung, 1996c) • Ordinance on Licensing of Transport (Verordnung, 1996d) Ordinances that create a basis for further deregulation of supervision • Ordinance on Waste Management Concepts and Waste Life Cycle Analysis (Verordnung, 1996e) • Ordinance on Specialised Waste Management Companies (Verordnung, 1996f) • Directive on the Activities and Approval of Waste Management Partnerships
In 1992 a statutory ordinance was drafted in the context of construction and demolition waste (ZBV, 1992), containing the requirements of waste prevention, recovery and disposal without affecting the quality of the environment. It also contains quantitative targets for waste recovery and recycling with a recycling rate of 60% to be met by 1995. In 1996 a new draft was launched containing requirements for demolition or deconstruction (ZBV, 1996). The draft requested, among other things, a deconstruction plan enabling a separation of recyclable materials. The draft established that the disposal of recyclable construction and demolition waste should be reduced by 50%, based on 1995 levels, by 2005. Though these two drafts have not thus far come into force they spawned a Voluntary Agreement (FSBW, 1996) signed in 1996 by several industrial organisations. The Agreement mainly focused on construction and demolition waste management and set out the goal of achieving the targets laid out in the draft ordinances. Table 2 shows the measures included in this agreement. Table 2: measure related with C&D waste from the Voluntary agreement of 1996 Source: Schultmann (2001) Measures • Information and advisory services to be made available to construction and demolition companies • R&D about avoidance of construction and demolition waste, separation and sorting of wastes and recovery measures, quality assurance for recycled materials and promotion of applications for recycled materials.
The Commercial Wastes Ordinance entered into force on 1 January 2003. It regulates the separation of certain types of waste from commercial enterprises that is suitable for recycling and the construction waste sector. Where mixtures are nevertheless submitted to recycling, they must only contain these specific, recyclable categories of waste and no other waste which could impair recycling. The ordinance also obliges commercial enterprises to keep a residual waste container for wastes destined for disposal; it is assumed that as a general rule, commercial enterprises will also generate non-recyclable waste which must not be mixed together with the recyclable waste and must instead be disposed of separately. (BMU, 2003)
6 - 27.10.2006
In March 2003, the Waste Wood Ordinance entered into force. The legal framework of the Ordinance divides waste wood into four categories, according to pollutant type. Certain material or energetic recycling processes are only admissible for individual or multiple waste wood categories. Affected parties are responsible for keeping records and arranging periodic external controls to verify their compliance with these provisions. Because waste wood can always be recycled, either materially or energetically, except contaminated waste wood, which must be thermally treated (incinerated), the dumping of waste wood on landfill sites is prohibited.

1.3
Responsibilities of Key Actors and related Economic Issues
As established by the Recycling and Waste Management Act of 1996, the waste producer is ultimately responsible for the disposal of any waste they generate. In Germany however all actors in the building material cycle share responsibility in facilitating the feasibility of reducing, recovering and recycling of C&D waste. 7 - 27.10.2006
As per § 22 KrW /AbfG construction material manufacturers are responsible for ensuring that their products are designed in such a way as to reduce wastage (eg: different lengths of floorboards to reduce cutoffs), facilitate recovery after usage, work towards making them recyclable and make them environmentally compatible with post recovery applications. Building owners, developers and their agents (engineers and architects) are responsible for integrating a waste management strategy into their construction plan. This includes the use of recyclable building materials. Despite this being a regulatory requirement recyclable buildings provide developers and owners with cost advantages as demolition materials that can not be recycled must be disposed, making them a financial liability rather than a valuable asset. Demolition contractors have a special multi role responsibility in the C&D waste management process. They provide invaluable service to building owners by taking over responsibility of recovering, treating, processing and marketing a building’s materials. To accomplish this demolition and recycling contractors must demolish buildings in such a way that material recovery and recycling is made possible. They are bound to do this both by legal considerations as set out in the regulatory requirements for C&D waste management and financial interest. A demolition company is responsible for the marketing of recovered demolition materials and can earn a significant portion of its revenues through the sale of recovered and recycled building materials. Part of the market competitiveness of a demolition company is their ability to offer demolition services at low or no cost (occasionally they will pay the building owner). The company that can extract the highest value possible from demolition wastes will be the most competitive and profitable on the market. This arrangement bodes particularly well for ensuring the recovery of waste as either the building owner or demolitions contractor face large costs if recovered C&D waste is contaminated. Not only does the responsible party lose the sale value of the material but they must also pay for disposal of the contaminated material in a landfill or incinerator.
Voluntary Industry Initiative
8 - 27.10.2006
Working Group on Closed Loop Recycling Management in Construction www.arge-kwtb.de The “Working Group on Closed Loop Recycling Management in Construction “ (ARGE KWTB) is an initiative of all trade associations involved in the building process. Its primary objective is to promote and develop a Closed Loop Recycling System in the construction industry. The ARGE KWTB was founded in 1995. In 1996, the organisation made a committed to the government to reduce by 50% the volume of recyclable construction waste disposed in landfills by 2005. This obligation has been met annually since 1996. Performance of the C&D waste and recycling industry are reported every two years to the Federal Ministry of the Environment. For a resource-saving, sustainable closed loop recycling system it is necessary -to avoid construction waste, e.g. by preserving existing building fabric and construction that has been built for a long useful life. -to keep construction waste in the economic cycle, e.g. by maintaining nearly homogeneous division of substances, by recycling methods that allow good future reutilisation of the material and by the adequate use of recycled construction waste. - to reduce the disposal of construction waste to the inevitable minimum and to avoid the disposal of recyclable construction waste.

According to the KWTBau (2005), the 73.0 Mt of generated C&D waste excluding excavated material, generated 51.1 Mt of recycled material, representing a 70% rate of recovery. From these 51.1 Mt of recycled construction materials, 18.0 Mt (35.2%) were treated in 639 stationary plants. The other 33.1 Mt (64.8 %) were treated in mobile/semimobile plants, the number of which cannot be established due to the possible double-use of the plants in different locations. Data from Destatis (2004b) indicates that the total number of operators of plants is 2,011. In the case of building demolition waste, KWTBau (2005) determined that from the 52.1 Mt corresponding to this item, 35.7 Mt were recycled representing a 68.5% recyclingrate. 7.0 Mt (13.4%) were used in mining installations and 3.8 Mt (7.3%) were directly used by public authorities. 1.6 Mt (3.1%) were used for landfill construction and 4.0 Mt were landfilled. (Figure 7) From the 16.6 Mt of road demolition waste generated in 2002, 14.2 Mt (85.5%) were recycled (KWTBau, 2005). 1.7 Mt (10.2%) were used by public authorities, 0.3 Mt (1,9%) were used in mining installations, 0.1 Mt (0.6%) were used in landfill installations and 0.3 Mt were landfilled. (Figure 8)

Excavation material represents the bigger amount of C&D waste generated in Germany in 2002 with 140.9 Mt. From these amount (see figure 10), 74.4 Mt (52.8%) was used in mining installations, 35.8 Mt (25.4%) were used by public authorities, 6.1 Mt (4.3%) were recycled, 3,6 Mt (2.6%) were used in landfills and 21.0 Mt were landfilled.

Application of Recycled C&D Waste Germany’s annual raw construction material demand is far higher than the annual amount of recycled building material, implying that all recycled C&D material can potentially be absorbed by the construction industry alone. This is not however the case and it appears that a major reason is that engineers and architects have not been able to specify recycled material without assurances that it will perform equivalent to new materials. Much progress, however, has been made in this regard, particularly in terms of setting and verifying engineering standards for recycled building material, particularly for use in higher value applications. While applications such as road construction are valid and cost effective for many C&D materials they imply a downcycling aspect, for example, from structural components such as brick and concrete, to road base crush. The German Institute for Quality Assurance and Marking operates a certification program for C&D material allowing recyclers to market their materials with the confidence that they are suitable for a particular application. Likewise a builder or material specifier (architect or engineer) may compare new materials with certified recycled materials, and take better advantage of the cost savings and ecological benefits inherent in recycled material. Germany has elaborated several regulations and indications determining standards for recycling materials in order to utilize them and make them an alternative to new materials. Most of them are used in road construction. Some guidelines for the use of recycled mineral materials in Germany are shown in table 6.

Financial liability for their C&D waste Must dispose themselves or contract out the responsibility
Economic Flows Who pays whom for what...
The owner of a given material is ultimately liable for the cost of disposal of that material. Demolition and recycling firms are often contracted to take over responsibility for a material and in doing so, often buy the material from the owner. They then process and market it. All disposal costs are born by the C&D contractor or its clients.
Economic Impact Dimension of waste market or construction

Overview of construction waste materials in Germany
Of Germany’s annual total C&D waste stream, materials resulting directly from demolition and construction site waste account for only about a quarter of the annual total. These materials are however, both of higher value and more difficult to recover and process for reuse. Road demolition waste can often be reused onsite or for other roadwork but it may also be used to as site recovery backfill in mining, gavel and sand pits. Such usage is normally reserved for excavation material. The only requirement before such usage of C&D waste is ensuring the environmental inertness of the material and treating it if necessary. Recovering and recycling of building specific C&D waste involves separating materials from each other during or after demolition/deconstruction and processing each according to their specific properties and potential uses. Statistical data on the Germany wide material composition of C&D waste is unfortunately not available. Some regional studies, however, can serve as relevant examples. A study by the French-German Institute for Environmental Research conducted in the Upper-Rhine Region and a study by the Hamburg Urban Development, Environment and Waste Authority of compiled statistics from Hamburg and Schleswig Holstein reveal the following breakdowns of C&D waste: Gypsumand Mortar 9.2% Metals 0.2%
Mixed building and Tar free bitumen demolition waste , mixes, 17.7% 17.7%
Plastics 0.6%
Wood, 2.5% ,
Concrete 25.5% Bricks and Stones 50.2% Wood 13.4%
Steel 0.9%

Metal and Plastics , 2.4% Gypsum contaminated waste , 0.6%
Figure 11: Composition of building demolition material, Upper-Rhine Region
Figure 12: Composition of building demolition material, Hamburg and Schleswig-Holstein
In both studies, concrete, bricks and rubble resulting from either or other materials are the most common material by far. The mixed results of other materials may be due to the different measuring techniques, samples and regional differences in construction methods but highlights the requirement for standard classification of materials in order to avoid confusion among actors in the C&D waste recycling industry. Germany has adopted the EU’s waste classification system into law and classifies all types and varieties of C&D wastes as shown below.

The methods for recycling each of these materials is crucial to the economic and practical feasibility of recovering them in the first place. Wood is widely sought after by recyclers due to its wide use in energy generation. Germany boasts widespread adoption of wood based electricity and heat generation from the residential to industrial and utility scale. Other materials, like metals, have established worldwide markets for recycling while others, like recovered concrete have limited and often local markets, for example in road construction. In order to insure the substitutability of recycled materials for new materials, a quality assurance system has been established in Germany. The Laendersarbeitgemeinschaft Abfall (LAGA) has established strict codes to which recycled material must conform in order to be reused in further applications. These codes give recyclers and contractors clear indications about what can and can not be done with a particular material, also facilitating effective estimation of a C&D waste value or cost. Quality assurance of course involves more than simply publishing specifications. Each load of material must be inspected and certified by a third party in order to be considered of sufficient quality for use in applications like road construction, new concrete or even backfill. This certification of material is carried out by RAL, the German Institute for Quality Assurance and Labelling. They can verify that a material conforms to the standards set by either LAGA or the more established DIN (Deutsches Institut fuer Normung) for use in a particular class of applications and apply the appropriate label. In this way, recyclers can sell their product to customers as equivalent to new material. Equivalence to virgin materials is likely the most important factor in assuring useability of recycled C&D materials. Achieving such material quality is highly dependant upon the unique challenges and obstacles presented by each material in the C&D waste stream. A solid understanding of these material properties is crucial to effective recycling. The following Factsheets describe the unique contexts and properties of each significant material in the waste stream, as well as the post recycling uses, both real and potential.

Material Fact Sheet CONCRETE
Material
CONCRETE Normal concrete as per DIN 1045, steel reinforced concrete, concrete brick, waste concrete Concrete is produced from cement (binder), aggregate, water and additives, when required. It is cast on site in shuttering, or as blocks or concrete elements. With few exceptions, the products are reinforced. Cement-based products Foamed concrete It consists of Portland cement and fine sand in proportions of about half and half. Foamed concrete is seldom use in building construction because its relatively low thermal insulation and low load-bearing capacity. The environmental aspects of this concrete are the same as in situ concrete. Aerated concrete Aerated concrete is produced by reacting finely powdered quartz (about 50 percent by weight) with lime, gypsum and cement. A yeast constituent such as aluminium powder is added to a proportion of about 0.1 percent. Aerated concrete is the only commercial pure mineral block with good structural properties and a high thermal insulation value. (Ayres, 1999) Aerated concrete can be considered inert and problem free as waste. Both prefabricated units and the blocks can be re-used, depending upon how they were laid and the mortar used. Crushed aerated concrete can be used as insulating granules for road building, and also as aggregate in lime sandstone, different light mortars and light concretes. Concrete with light aggregate This is usually produced as blocks, slabs or floor beam units, which are relatively strong. There is a difference between products that have an organic and a mineral aggregate. Mineral insulating aggregate in concrete can be light expanded clay, pumice, fossil meal and exfoliated vermiculite, perlite or slag (Berge, 2000). Sawdust and chopped straw can be used as organic constituents in concrete. Raw materials for concrete 23 - 27.10.2006
with light aggregate are widely available. Origin Concrete is the primary material for larger buildings in foundations, retaining walls, walls, roofs and floor construction. It is also used as pavement on roads. REUSE
Some concrete can be reused with little processing: a) Pre Fabricated elements b) Concrete Block (once cleaned of mortar and finishes)
Ways of collection
Ways of sorting Reuse
Technologies Market
Collection of prefabricated sections and blocks requires careful dismantling of a building. This may be time consuming but, if the material costs saving are high enough, well worth it. Different techniques are possible but all must avoid damaging the material as this will prevent reuse. Some concrete components can be reused with little processing: c) Pre Fabricated elements d) Concrete Block (once cleaned of mortar and finishes) Concrete saws, grinders, lifts The market for recycled concrete is primarily in road construction as underlays and drainage material. Ideally, recycled concrete could be used as aggregate in new concrete and some progress has been made towards the normalisation of this process. Challenges do however still exist and so long as virgin material prices are competitive recycled concrete will remain primarily dependant on the road construction market.
RECYCLING The value of in-situ concrete in terms of recycling is low (Berge, 2000). It can be crushed and ground to aggregate. The majority of it has to be sorted and used as fill. Road base and construction fill Crushed concrete can be used as base fill in the construction of roads. The crushed material is used in place of lime rock. The benefits of such reuse are often 24 - 27.10.2006
dictated by the local availability of lime rock deposits, as hauling costs are substantial. The purity (i.e. presence of wood, dirt, other contamination) of the material may also be an issue. Crushed concrete may also be used as primary road surface material on unpaved roads in rural areas. The use of crushed concrete for driveways can also be practiced. The limitation for this use comes from the crushing of the material, which should be ideally made on site to avoid hauling costs. Aggregate in concrete Crushed concrete has been proposed for use as aggregate in the manufacture of new concrete. According to Townsend (1999), the addition of crushed concrete fines has been used, but the quality does not always meet the same results as when using clean sand and rock aggregate. Drainage material Crushed concrete that has been well screened of fine particles provides similar drainage characteristics as new rock or gravel. It can be used for drainage applications in construction. Other possibilities include septic drain fields and landfill leachate collection systems. Crushed concrete does raise the pH of water in contact with it, so care must be taken if this presents a concern with regard to water quality (i.e. impact on a surface water or groundwater supply). Ways of collection Recovered from concrete demolition sites unprocessed or preferably, pre crushed by excavator breaker or mobile crushing machine. Reduced volume of concrete allows for fewer loads and lower transport costs. Ways of sorting

Material Fact Sheet WOOD
Material Origin
WOOD, TIMBER Timber has been the main structural and covering material in the county all over the world. In the case of roof construction, its lightweight and structural properties have made it more attractive than any other alternative. Timber can be used to cover roofs as shakes, shingles or planks. As cladding it can be used as panelling or wattle, and as flooring it can be used as boards, parquet tiles or timber sets. The sheeting is produced as fiberboard, cork, chipboard or veneer.
REUSE
Ways of collection Ways of sorting Reuse Technologies Market
Considerable quantities of reusable timber can be recovered during the demolition of old buildings. Older buildings can have valuable timbers which were prevalent in the past but which are now quite rare. Demolition of older or unique structures can also yield materials such as wooden fixtures, moldings, and framings in addition to structural timber, which can be resold, reused or re-milled. Collection of wood for direct reuse is largely done manually, with the aid of powered hand tools Reuseable wood is sorted by type, size and quality a) Direct use when free of pollutants b) Removal of nails and foreign objects, planing, surface treatment Saws, hand tools, planers, sanders Woodworking Larger pieces of the highest quality recovered wood, such as barn boards and structural timbers can be used intact. They are largely used by the woodworking industry as raw material for furniture, flooring and specialty items.

Ways of sorting
Recycling Process
Technologies
Recovered wood is sorted by material quality, degree of contamination, size and type. Further sorting is carried out according to intended processing.
1. Wood is collected onsite with or without foreign materials. 2. Sorting is done by hand and machine 3. Wood is shredded, sometimes onsite and sometimes with foreign matter 4. Further separation, like air blower and magnetic is performed on shredded material 5. Shredded wood is marketed
Shredders Single-Shaft-Shredder
The high performance shredders from Weima’s Jumbo/Super Jumbo range of machines are specially designed for the wood processing and wood recycling industries where very large quantities of wood are shredded. The rotors, depending on the model type, are 1000 mm to 3000 mm long. This extremely high shredding capacity is guaranteed by rotors which have a diameter of 482 mm (Jumbo) and 600 mm (Super Jumbo).

Powerline
Extremely high output rates, highly economical The Powerline shredder series are designed specially for the production of substitute fuels (RDF) and offer a wide variety of innovative equipment and ancillaries. A high output rate for all types of materials such as industrial, household and bulk waste, mixed construction site waste, production rejects, timber, paper, paper rejects etc. guarantees a maximum rate of productivity. Low power consumption and low wear costs are the basis for the Powerline's economic efficiency.
Single shaft shredder The single shaft shredders of the newPowerline series were developed from the basis of installation experience and are designed specifically for the production of substitute fuels. Along with the material to be shredded, the throughput rate and material size range determines the individual specification of the machine. More than 40 different machine options are available.
34 - 27.10.2006
Knife system The knife bearers are screwed or welded onto the rotor depending on requirements. The multi-turn and regrindable rotor knives, as well as the newly developed stator knife system guarantee a considerable reduction in wear costs. A durable hydraulic drive system is available for highly contaminated feedstock. The electro-mechanical drive with frequency converter guarantees maximum throughput rates for clean and pre-treated materials. Market/Products
Fuel The most common reuse option for wood recovered from C&D recycling is for fuel. Wood has a high heating value and can be used by a number of industries as boiler fuel. Wood for fuel can be chipped or pelletised for better transportation. Wood with minimal soil and other foreign objects, and low moisture content is ideal. The presence of large amounts of treated wood creates air emission control and ash disposal problems. Treated wood should be removed from the recovered wood stream prior to grinding. (Metro, 2002) Biomass could provide for more than 10% of Germany’s present primary energy consumption needs. Though this goal in far away, operators such as EnBW power stations AG are building and successfully producing heat and electricity from waste wood and biomass. Engineered wood A number of engineered wood products can be produced from chipped wood material. These products include fiberboard, oriented strand board, and particleboard. The wood chips are formed into boards by various pressing methods and adhesives. No foreign materials should be present. Mulch Chipped wood may be used for mulch in horticultural and agricultural applications. The wood should be free of foreign material as much as possible and should contain no treated 35 - 27.10.2006
wood. The reuse possibilities of mulch from recovered C&D wood typically revolves around aesthetics. Foreign materials such as nails and plastic greatly limit appeal (MEO, 2004). Animal bedding and compost amendment Two other applications for recovered C&D wood that are sometimes performed because of its moisture absorptive capacity are animal bedding and bulking agent in composting. These uses require a clean wood stream in terms of foreign material. No treated wood should be present (EPA-AU, 2002; Reinhart, 2002). Price per unit (if available) Regulations
Wood Pellets: €180.20/tonne (2005) (Solar Promotion GmbH) AltholzVO According to Wood Waste Ordinance (AltholzV) Waste wood must be assigned to one of four waste wood categories and one special category: A I: Waste wood in its natural state or only mechanically worked which, during use, was at most insignificantly contaminated with substances harmful to wood (e.g. natural solid wood) A II: Bonded, painted, coated, lacquered or otherwise treated waste wood with no halogenated organic compounds in the coating and no wood preservatives (e.g. interior doors) A III: Waste wood with halogenated organic compounds in the coating, with no wood preservatives, (e.g. PVC-coated furniture) A IV: Waste wood treated with wood preservatives, such as railway sleepers, telephone masts, hop poles, vine poles as well as other waste wood which, due to its contamination, cannot be assigned to waste wood categories A I, A II or A III, with the exception of waste wood containing PCBs Waste wood containing PCBs: Waste wood which constitutes “waste wood containing PCBs” within the meaning of the “PCB/PCT Waste Ordinance” (a total of more than 50 mg/kg PCB or similar substances) and which is to be disposed of in accordance with the provisions of this Ordinance (e.g. sound insulating board treated with agents containing PCB). This can only be done with the help of thermal waste disposal plants.

Material Fact Sheet METAL (Steel)
Material Origin
METAL (Steel) Steel is the most important structural metal, and is used in all the structural components of a building, from foundations (usually combined with concrete) to the roof. Steel used in structural cases is often unalloyed. High quality steel is alloyed with small amounts of aluminium and titanium. The resulting material is particularly strong, and means that the amount of material used can be reduced by up to 50 percent (UKSA, 2005). Germany’s annual quantity of scrap steel is approx. 29 million tonnes, 22 million of which are supplied by the steel recycling industry. World-wide about 45% of raw steel production is based on the employment of scrap steel. Other than steel and iron a number of other metals are encountered, particularly in sheeting applications, and recovered from the C&D waste stream.

RECYCLING In 2000, 42 % of German steel was produced from scrap. The foundry industry produced approximately 5.3 million tonnes of cast steel in the same year. According to data the German Foundry Federation this was 88% more scrap utilisation than in the previous 37 - 27.10.2006
year. Germany’s foundry industry is highly dependant on scrap metal. Steel is an ideal recycling material as it does not lose quality in process. Greenhouse missions savings associated with steel recycling are significant amount in Germany to 27 million tonnes or 86% over virgin material only. Each tonne of steel scrap used negates the use of 1.5t of iron ore, 0.5t of coal oil and significant savings on transportation. Steel production with scrap steel requires 90% less energy than with virgin materials. Ways of collection
Metals recovered from C&D waste may be directly removed from a building already segregated from other materials. Large sections may be cut or shredded onsite before transport. When collected in conjunction with other materials such as concrete, brick, wood, plastic and others metals must be sorted out from other materials at a central processing site.
Ways of sorting
Density Separation Manual separation Magnetic Separation Eddy Current Separation The steel recycling process involves collecting unalloyed and alloyed scrap, sorting it manually or by magnetic separation, shredding, further sorting of reduced material and marketing it domestically or internationally to foundries.
Recycling Process
Both collected old scrap and new scrap, from manufacturing, is sorted according to internationally agreed lists, ensuring homogenous high quality materials that, once processed by shears or shredder, can go directly into the furnace for production. In this fashion secondary raw material is interchangeable with primary raw material. Technologies
In Germany two different steel production methods are used, each with different possible levels of scrap steel content. The Oxygen Steelmaking Method (in 2000 approx. 71 % of total production) works with a scrap iron employment between 20 % and 30 %. The Electric Arc Furnace steel production method (approx. 29 % of 2000 production) is capable of employing 100 percent scrap metal in production.
Market/Products
Processed or unprocessed scrap steel is sold internationally and provides the raw material for roughly half of the world’s 790 million tonnes of annual steel production Processed scrap may also be used in place of crushed stone 38 - 27.10.2006

Regulations Long before the entry into law of the Closed Substance Cycle Waste Management in 1996, the German steel recycling industry was meeting goals set out in the EU’s Agenda 21 initiative. Today, documentation, certification and industry wide quality management systems ensure a high quality of recycled steel material. This allows for even more steel to be recycled, yielding important cost, resource and energy savings. Cross references to companies

Aluminium is a metallic material often used in light structures and as roofing or exterior siding material. Its properties and characteristics are not affected even after it has been used in a product. Therefore aluminium can be recycled and re-used, after having undergone adequate treatment and preparation, as often as necessary without any loss in quality. The high value of the metal is maintained through multiple reapplication cycles, guaranteeing sufficient economic incentive for its collection and recycling into a similar or comparable product.
The recovery and recycling of aluminium is carried out by metal merchants, processors, aluminium refiners and remelters, the latter two groups form the end of the recycling process as producers of casting and wrought alloys. However, the aluminium recycling industry also counts among its members those companies which treat and process salt slags and filter dust, both arising during production. They contribute to the fact that Germany has already largely reached the goal of recovering and recycling aluminium without leaving any residues behind.

Recycling Process
Collection and recovery Old and new scrap are collected and recovered by the metal trade or the refiners and remelters themselves. Preparation and treatment The scraps recovered are treated according to their quality and characteristics. Common treatment processes are for example sorting, cutting, baling or shredding. Turnings are dried and crushed. Free iron is removed by magnetic separators. Aluminium skimmings, a mixture of aluminium metal and aluminium oxide, are crushed or ground and air separated. Charging As a rule computer controlled selection and mixing of scrap types whose chemical composition is as close as possible to that of the required alloy. Melting Various furnace types are available for melting aluminium scrap. In Germany, scrap for the production of casting alloys is commonly melted in rotary furnaces under a layer of liquid melting salt (flux). Producers of wrought alloys prefer open hearth furnaces in varying designs. Refining The alloy production in rotary furnaces is followed by a refining process. The molten alloy is fed into a holding furnace (converter) and purified through the addition of refining agents. Quality control Every single charge of the furnace is tested in the plants’ laboratories with modern computer controlled analytical technology equipment and, provided that the result is positive, receives a certificate. Casting The molten aluminium is either cast into ingots or transported in liquid form to a foundry. The ingots weigh, depending on the shape of the mould used, between 4 and 25 kg. Liquid aluminium is filled into pre-heated thermos containers and transported to the foundries, where the liquid metal is filled into 41 - 27.10.2006
holding furnaces and processed immediately. Homogenising Heat treatment of extrusion billets in special furnaces in order to obtain a metal structure which is appropriate for further processing and to remove residual stress of the casting. Technologies Market/Products
Shears, Shredders, Magnetic and Eddy Current Separators, Furnaces, etc. Scrap aluminium from product manufacture or at the end of a product's service life becomes a secondary raw material which has markets world-wide. Primarily two kinds of firms purchase aluminium scrap. Refiner Produces casting alloys and deoxidised aluminium from old and new scrap and supplies them in the shape of ingots and liquid aluminium. Remelter Produces wrought alloys from mainly clean and sorted wrought alloy scrap and supplies them in the shape of rolling slabs, extrusion billets or master alloys. In Germany, the aluminium recycling business provides about 20,000 jobs.
Casting alloys Casting alloy, standardised or produced according to specific customer requirements, are supplied in ingot or liquid form to foundries which cast them into high quality components. Typical applications are cylinder heads, engine blocks or gear boxes in automobiles, components and parts in the mechanical and electrical engineering industries, casings for household equipment etc. Wrought alloys Wrought alloys are predominantly cast directly into extrusion billets and rolling slabs. Typical wrought alloy products are 42 - 27.10.2006
semifabricated items in the form of sheet, foils or profiles, which are processed into automobile body parts, commercial vehicle constructions, rail vehicles, doors and windows, packaging, etc. Deoxidised aluminium Deoxidised aluminium consists of alloys with a high share of aluminium (usually exceeding 95 %) in the form of waffle plates consisting of one or more parts, granules or pellets, which are used to remove free oxygen from the liquid steel. Scale At present, German refiners produce about 626,600 tonnes of casting alloys annually from secondary raw materials. EU annual production is in the range of 2.3 million tonnes. Quantities of aluminum alloys made from secondary raw materials can at present only be estimated, with European production figures being in the range of 3.5 million tonnes (turnaround scrap included).

Material Fact Sheet ASBESTOS
Material Origin
ASBESTOS Asbestos is the name for a group of naturally occurring, fibrous minerals. White asbestos (Chrysotil) and blue asbestos (Krokydolith) were most frequently used. Since asbestos is extraordinarily heatproof and very chemically stable, it was used for the production of various products. It was applied in two forms. Firm fiber (non-friable) connection asbestos was used in cement products, pipes, and other building materials. It was also widely used in brake linings. Such materials are stable and present fewer risks. Weak fiber connection (friable) asbestos was often in the form of asbestos sprayed on as fire protection. It was also however used in asbestos boards, precast plates, electric insulation, noise insulation and heat and vapour protection. Asbestos contaminated wastes occur particularly in the demolition, reorganization or maintenance of old buildings. It is regulated as a dangerous material and the methods and requirements for disposal are specificied in the regulation.
Danger
Products with weak fiber (friable) asbestos are particularly dangerous. Inhaled asbestos fibers are known to cause Asbestosis and/or cancers. Due to its carcinogenic effect asbestos is classified in the dangerous material regulation as a particularly dangerous carcinogenic dangerous material. As a result the prevention of asbestos fibers from becoming airborne is a very important public health measure that must be undertaken in the demolition of old buildings.
Disposal
The intended measures orient themselves at the hazard potential of the different asbestos contaminated wastes.
Ways of collection
In order to make possible the processing of the usable components of building wastes as well as the normal disposal of the asbestos contaminated components the following work routine must be observed: - Before beginning of demolition and/or renovation, an examination of asbestos 51 - 27.10.2006
-
-
contaminated materials and components is conducted If asbestos contamination is present – a specification of the demolition or deconstruction process must be provided to the responsible authorities. Before beginning of the demolition and/or renovation asbestos contaminated materials are to be removed and disposed according to the provided procedure.
Asbestos contaminated components such as steel girders, air ducts etc do not need to be disposed as asbestos contaminated wastes, so long as they are cleaned sufficiently according to TRGS 519. Once clean they can be reused. Ways of sorting
Asbestos in a pure form is separated from materials with asbestos contamination and these materials are further separated between those to be cleaned and those to be disposed. Sorting is important in order to ensure appropriate treatment for each particular type of asbestos form.
Disposal Process
Generally, asbestos and materials contaminated with asbestos are stabilised and disposed of in specifically identified areas of landfills.
Technologies
At present chemical, thermal and mechanical procedures for asbestos fiber destruction are in different stages of development and testing. Until the establishment and operation of such plants the requirements of Germany’s federal Emmission Control law apply. Sprayed asbestos and asbestos types of dust, which are to be disposed, are to be preferably solidified or stabilised by means of suitable inorganic bonding agents, like glass, at the point of accumulation. Depending upon the condition of the asbestos contaminated wastes (excluding sprayed asbestos and asbestos types of dust) different methods of the surface treatment or the packing are necessary. Wastes accompanying asbestos removal operations, primarily those with organic compounds, (e.g. carpets, textiles, curtains etc.) must be thermally treated and brought to landfill in stable, depositable form. Chemical procedures for the chemical treatment of asbestos contaminated wastes largely use hydrofluoric acid. Byproducts of this neutralisation process include calcium fluoride, metallic oxides and hydroxides as well as silica. Use of the byproducts of asbestos treatment are 52 - 27.10.2006
directed at cement and concrete production, as fluxing agent and as secondary raw material for hydrofluoric acid Thermal procedures include a) Vitrification of asbestos contaminated wastes involves melting them at temperatures around 1400° C. Asbestos-free glass granulates are the process output. b) Asbestos minerals are converted in special rotary kilns at temperatures by 800° C into other minerals, such as forsterite and olivin.

MIXED CONSTRUCTION WASTE
REUSE
Reuse of mixed construction waste is unusual without some sort of treatment. If the mixed waste is specifically mineral and has very little contamination it may be reused directly as construction or mine backfill.
Mixed building site wastes arise from construction, renovation, and demolition and contain mixtures of building materials, accessories, packing materials and household waste like components. These materials are often both mineral and non-mineral (concrete remainders, stones, glass, wood, scrap iron, packing, insulating materials, carpet remainders, aerated concrete, plastics etc.).
Ways of collection Ways of sorting Reuse Technologies Market Price per unit (if available) RECYCLING
No overall statement can be made regarding Germany’s quantities of mixed construction waste. But generally, they are composed primarily of excavation or mineral materials with smaller fractions of wood, plastics, metals, paper and packing materials.
Ways of collection
Through planned and controlled waste separation already running on building sites, a large part of the wastes can be recovered as valuable material. Many can be used in material or thermal applications. Clear examples are: glass, plastics, iron and non-ferrous metals is considered.
Ways of sorting
Due to its heterogeneity the processing of building site mixing wastes is technically more complex than with mineral building debris. A complete sorting of mixed building site wastes is so far only possible with manual labour. Commercial waste producers however, are obliged to separate their mixed wastes by law and thus mixed building waste quantities should be limited and/or feasibly sorted machine. 54 - 27.10.2006

Overview of construction waste companies in Germany German demolition and construction waste companies are the vital link in the C&D waste management chain. They possess the technical knowledge, equipment, training and organisation vital to an effective recover C&D waste management system. Furthermore, they play an important role in the construction industry by assuming responsibility for the dismantling, processing, marketing, sale or disposal of all building related wastes. They have significant incentives to improve their techniques and the quality of the material they process because they often also earn a proportion of their revenue from selling the material they recycle. The below table lists the average deposit fees and recycling costs for various types of materials in Germany. Table 7: Comparison on Recycling and Disposal Costs

It should also be noted that the ability of a recycler to earn revenues with the material they receive can affects the cost of recycling to the material owner. If the material is of higher quality and recovered in a manner that preserves this 56 - 27.10.2006
quality a recycler may be able to sell it as a higher valuable material and pass on some of these earnings to the original material owner in the form of lower recycling costs. Scale of C&D Waste Management Industry Rest (waste fro m building sites, demo litio n wo o d) 1.924,9 3,2%

Economics Germany’s entire recycling market recorded a 2004 turnover of 4.94 billion Euros. Employment in the industry grew from 13375 employees in 2000 to over 17000 in 2004. (Eurostat 2006) While some of this economic activity and employment accounts for the recycling of household and commercial wastes, C&D wastes account for a large portion of the overall waste mix, implying that a significant portion of these numbers can be attributed specifically to the C&D recycling industry. While these statistics are encouraging, they reflect only one side of the economics of recycling. The Cologne Institute for Economic Research estimates that the use of secondary raw materials added 3.7 billion to German GDP in 2005 in terms of avoided material costs. Such savings are particularly significant for materials that are in short supply or regularly imported.

4 CONCLUSIONS Germany has a successful and effective construction and demolition waste management system. The recovery, reuse and recycling of these waste materials ensures the diversion of what was historically the largest portion of the waste mix. Simultaneously, the demand for new materials is reduced, conserving domestically available virgin materials and energy while reducing the need for imports. A particularly important challenge in any waste management system is ensuring consistent, high quality recycled material. The roles of LAGA in publishing specifications for recycled materials and RAL in inspecting and labelling materials for quality assurance are key to the smooth running of a the German recycled C&D waste materials market. Without the vital contribution of specification and quality assurance, sellers and buyers would be forced to evaluate and negotiate every sale or purchase on a case by case basis. While the work of LAGA and RAL has simplified much of this process, implementation of these practices is still underway. There is however room for improvement in the performance of Germany’s construction material cycle. The potential for Germany’s C&D waste companies to provide even more savings is evident in the literature on the subject as indicated by the Schultmann and Co. in the following case study figure: 50 44,4

Figure 18: Comparison of costs for selective dismantling and conventional demolition
As is evident above, in Germany, the costs for recycling and disposal of demolition waste range are the same category as the costs for demolition. So it can be advantageous to dismantle as many building elements as possible if this leads to a decreasing of the recycling and disposal costs. (Schultmann, 2005) This is especially true if dismantling 78 - 27.10.2006
preserves the quality of the recovered materials, making them available for higher value uses than if they were simply demolished. This may go some length to addressing the phenomenon of downcycling in the C&D waste management cycle. A study of 70 recycled C&D waste material sales outlets by the Ruhr University of Bochum showed that more than 60% of recycled C&D material sold was used in road construction , particularly as crushed stone base and frost protection. An additional 30% of material was used in landscaping and earthworks (eg: soil stabilization) while reusable materials like tiles, fixtures and windows constituted the smallest portion of sales. The more specific of Hamburg and Schleswig-Holstein’s experience with C&D recycling show that while nearly 90% of the 10 million Mt of C&D materials are recovered, only about 40% of this material is reabsorbed by the construction industry. The remainder, largely mineral materials resulting from excavation is used to backfill old gravel and sand pits. Road construction is a notable exception to this norm and is often able to achieve nearly 100% recycling of materials, sometimes in place and with significant savings in materials and energy. If a truly cyclical flow of construction materials is to be achieved, the preservation of material quality in demolition as well as the improvement of recycling of used material into new equivalent material requires some improvement. In today’s environment of high raw material prices and even higher energy costs there is significant incentive to take these steps towards improvement. It seems therefore, that Germany’s progressive success in abating the disposal of C&D wastes is bound to continue.
