Not all biodegradable products are compostable – the key difference between the two is time, since compostable products degrade within a cycle of a compost process. That’s months instead of decades.
The “Oh Crap” biodegradable compostable bag is specially formulated to have appropriate water resistance and disintegration. The “Oh Crap” collection bag can be used to collect the dog waste with certain water content without dissolution or breakage, and then disintegrate rapidly in landfill, and biodegrade completely – not into small pieces, completely gone. Since it’s fully biodegradable and compostable, it will not do any harm to people or the environment.
