Are compostable bags actually compostable?
Yes, they are. As a result of microbial activity in a composting system, compostable bags break down readily.
Biodegradable bags are often still plastic bags with microorganisms added to break them down.
Compostable products are gaining in popularity, with consumers striving to live a zero-waste lifestyle.
In addition to backyard composting and choosing to use a compost bin over a trash can for organic waste, we can all help do our part by purchasing and using compostable bags for kitchen trash bags, garbage bags, dog poop bags, and even bin liners.
Why you need a compostable trash bag
By composting, compostable bags not only eliminate any type of plastic or waste from landfills, but they also replenish the soil with needed nutrients.
It is important to note that biodegradable and compostable bags will break down more slowly in landfills than in your home composting system.
Without oxygen, they will produce methane, a much more dangerous greenhouse gas than carbon dioxide. In marine environments, biodegradable bags do not decompose.
