The unfortunate truth is that even if you use truly biodegradable poop bags proven to break down and return to nature in a relatively short period of time, they will not degrade well in a landfill, where compression and lack of oxygen get in the way of the degradation process. So instead of throwing your poop bags in the regular trash, what can you do to go the extra ecological mile?
Flush the waste. Water-soluble bags, such as Flush Puppies Doodie Bags, can go down the toilet. Just check first with your municipal sewage utility, and don’t do it if you have a septic tank.
Bury the evidence. Dog excrement in biodegradable bags should be buried at least about a half foot underground — away from gardens where food grows and underground wells and aquifers that supply water to homes.
Invest in a dog-waste-only composting bin, such as the Doggie Dooley. Such compost (into which you can also throw the biodegradable bags) should never be used on plants that grow vegetables and other foods, but it makes great fertilizer for flower gardens.
If you’re not going to do any of those things (and we totally understand), the planet is still better off with biodegradable bags like BioBag Pet Waste Bags rather than regular plastic.
