Landfills make methane gas, weather you put compost in or not. You are required to collect, contain, burn or distribute the gas. You cannot let it migrate off site.
We are required to have the tag on freon filled appliances. We don't make the rules, we follow the rules. Sorry guys.
The big appliances that we collect here we store and sell usually. They take up space, which is precious. Why bury when you can sell, or someone pick up for free?
