Biodegradable refers to the ability of the material, to break down by the metabolism of micro-organisms and return to nature. For packaging products to qualify as biodegradable, they must completely break down and decompose into natural elements (CO2, H2O, methane, biomass, and mineral salts) within a short time after disposal – typically a year or less. The ability to biodegrade within landfills helps to reduce the buildup of waste and contributes to a safer, cleaner and healthier environment.
