It is very important to dispose of any and all products in a responsible manner to make sure they do not reach waterways. When foreign material ends up in bodies of water, marine habitats are disrupted and wildlife is harmed.
A 2012 study from CalRecycle found that when our PLA products breakdown in a marine environment they do not release microplastics, toxic chemicals or other hazardous byproducts like oil-based plastics do. No matter where they end up, they have a lower carbon footprint than comparable non-compostable products.
