Can I use compostable bags in my backyard composter?

I don’t recommend you compost compostable bags on your own because composting bags requires a specific environment, such as proper temperature, enough moisture, and oxygen, which often fails to achieve in your backyard composter. You’d better send your compostable bags to the industrial compost site.
