There’s a new polymer on the market that biodegrades quickly in water, is transparent, and is non-toxic. Could replace poly bags for an eco-friendly alternative. http://www.cyberpac.co.uk/ http://www.creativereview.co.uk/cr-blog/2009/october/crs-incredible-dissolving-bag
"More details from Cyberpac on how it works, also in the comments below: "The hot water is just to show you the biodegradability at speed. You don’t need to boil it, just chuck it on the compost heap! We use this to package fish food as it dissolves in the water releasing the bait.
"Harmless-Dissolve is made from a hydro-degradable substrate which is 5 times stronger than normal polythene. It is a readily biodegradable, water soluble polymer which completely biodegrades in a composting environment, in a dishwasher or in a washing machine. It has no harmful residues and will biodegrade into naturally occuring substances - the bugs love it.
“It’s non-toxic and is degraded by micro-organisms, moulds and yeasts. These organisms can occur in both artificial environments, such as anaerobic digesters, activated sewage sludge and composts and natural environments such as aquatic systems and soil. The micro-organisms use Harmless-Dissolve as a food source by producing a variety of enzymes that are capable of reacting with it. In the end the bag becomes carbon dioxide, water and biomass.” More here
