Abstract
A biodegradable foam which includes a poly-ester-based polyurethane foam and a mixture comprised of a soil-dwelling carbon-digesting bacteria embedded in a carrier compound. The mixture of the soil-dwelling carbon-digesting bacteria is homogenously dispersed throughout the polyester-based polyurethane foam. This biodegradable foam exhibits biodegradation rates higher than a polyester-based polyurethane foam absent the soil-dwelling carbon-digesting bacteria.
Claims33
A biodegradable foam, comprising:
- a) polyester-based polyurethane foam;
- and
- b) a soil-dwelling carbon-digesting bacteria, or a mixture comprised of a soil-dwelling carbon-digesting bacteria embedded in a carrier compound, said soil-dwelling carbon-digesting bacteria or mixture substantially homogeneously dispersed throughout said polyester-based polyurethane foam, said polyester-based polyurethane foam containing said soil-dwelling carbon-digesting bacteria characterized in that it exhibits biodegradation rates higher than the same polyester-based polyurethane foam absent the soil-dwelling carbon-digesting bacteria.
