Removal and disposal REMOVAL

G3 polymers need not to be to removed from site After a simple and fast treatment G3 polymers can be disposed on site

DISPOSAL

Disposal procedure (30min): 1. Correct pH to 6 – 9 with hydrochloric acid (HCl) 2. Break the polymer chain with Calcium Hypochlorite After the treatment the polymer is ready to be disposed on the environment i t without ith t any risk i k (city ( it sewage, rivers, i on soil) il) 10.

Environmental issues and legal regulation ENVIRONMENTAL ISSUES

G3 polymers are environmentally friendly products GEO’s products are not contaminants, not pollutants and respect the environment LEGAL REGULATION

GEO’s products where approved to be disposed on the environment in: Example: Spain (CEDEX – Government lab for civil engineering and environment) GEO is keen to support further studies in other countries 11. Environmental Issues and Legal regulation

47

Storage and storage life STORAGE

G3 polymers after mixing may be stored in slurry tanks ready to use on site No special storage requirements. site. requirements AlfaBond should not be kept in negative temperatures below -10ºC STORAGE LIFE

We have never observed slurry degradation with time On the Cadiz bay Bridge (Marine Works- Spain) three marine pile were left open for 3 months for trial purposes. After 3 months piles were stable and the slurry kept the same stabilization t bili ti properties. ti 12. Removal and Disposal
