I looked into the biodegradable poop bags and want to share what I learned. They are made from corn and contain no polyethylene, and are completely compostable and biodegradable. Depending on the exact conditions, they typically decompose in a compost bin within 6 weeks. Because they “breathe,” odor is kept to a minimum since there is less bacterial build up than in bags that don’t breathe. They will not decompose or start to decay in any way just sitting on your shelf.
They will also fail to decompose with any sort of speed if put in the trash and taken to a landfill, which is not an environment conducive to such chemical processes. So, using them in an environmentally green way involves composting them, burying them, or disposing of them with yard waste, depending on whether that is allowed in your community.
Biodegradable bags are available in two sizes—the regular size is 8 by 12½ inches and the big size is 10 by 14 inches. They are available in packages of 50 regular bags for $7.49, which comes to 10 cents per bag. The big size is just over 20 cents a bag. Buying in larger quantities can reduce the price to as little as 5 cents each for regular and about 14 cents each for big bags.
Have you tried these bags, and if so, what is your experience with them?
