Abstract: A biodegradable foam which includes a polyester-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.
