  In almost all walks of life, starting from household utensils, clothes, furniture etc. to automobiles to space aircrafts, plastics are extensively use. Some of the things are provided by nature as such while most of the others are fabricated from natural resources by the people of different skills. In the past three decades the 1/3rd of planet¶s natural resources base have been consumed. As time passes, the humanity continues to slowly destroy the planet. So what can we do to stop our planet from being destroyed? Recycle. Recycling is the process of turning one products useful parts into a new product; this is done to conserve on the consumption of resources, energy and space used in landfills. By recycling1 plastic bottle not only saves anywhere from 100 to 1000 years in the landfill but also saves the environment from the emissions in producing new bottles as well as the oil used to produce that bottle. For every1 ton of plastic that is recycled we save the equivalent of 2 people¶s energy use for 1 year, the amount of water used by 1 person in 2 month¶s time and almost 2000 pounds of oil. Approximately 60% of our rubbish thrown away today could be recycled. A survey was done and 9 out of 10 people surveyed said they would recycle more if it was easier. Odd as it seems there are many people who do not realize that plastic bottles our water comes in is made out of oil. This is the same oil that is used to make gasoline. It's the same oil that is in such high demand and is not an unlimited resource.  ³Plastic is an organic material which on application of adequate heat and pressure can be caused to flow and take up a desired shape which will be retained when the applied heat and pressure are withdrawn.´ Chemically, a polymer is defined as a substance composed of very large molecules. The molecular structure corresponds to a chain composed of many small molecules joined by chemical bonds. One or more types of small molecules, also known as monomers, are incorporated into the polymer as it is synthesized in control conditions. From the view point of recycling, plastics (or polymers as it is known in the language of material sciences) can be subdivided in two main categories: thermoplastics, which consists of individual long chain molecules and any product made of this plastic can be reprocessed; and thermoset plastics which contain infinite three dimensional network which is formed when the product is in the final form and can not be broken down by reheating (Brandrup, 1975). Hence, for the purpose of this report only thermoplastics are analysed. By definition plastics can be reheated and modified in different shape. Theoretically this process can be repeated number of times but practically it depends upon the physical conditions in which it is processed and reprocessed.

By recycling the plastic water bottles in five areas it can be beneficial for you and your people. The five areas are, 1. 2. 3. 4. 5.

o Name of Company: SIDDHI POLYMERS o Address : Eagle I.P.C. unit No. 27, Pune-Mumbai Road, Opp. Sheetal Hotel, Vadgaon Maval, Dist. ± Pune ± 412106 o Approved ISO: An ISO 9001:2008 Company o Product Range: Moulding and Vacuum Forming o The product are sold in local and state.The production is done on the basis of orders received from customers. No excess production is done.The market requirement is more than a monthly firm plan.The waste material is purchased from market for reprocessing depends on the type of plastic like LDPE, LLDPE, HDPE etc. o The area of company is 25000 sq ft. o The storage is done at company¶s unit-1 where the suppliers delivers the waste material. o The company have quality control. The company believes in maintaining quality and provide quality products to the customers. The company holds ISO 9001. o For logistic, the supplier delivers directly to company. o To reduce cost of production, the company use gasoline instead of electricity which reduces cost of processing and helps in continue flow of work as power shutdown is done in the area. o The company fulfills customer order in the committed time. · The plastic recycling is very useful and beneficial for the planet. Today the recycling of plastic business is done and the entrepreneurs earns a huge money. The plastic recycling business creates over 200,000 jobs.
