The waste “disposal destination” is a field tracking where your waste went when it left your property. There are 4 options: Landfill, Incineration, Waste to Energy, or “Don’t Know/Other.” You don’t need to know the specific landfill (or incinerator or Waste to Energy plant). If you don’t know where your waste goes (and many people won’t), ask your waste hauler who should know. If your waste goes to more than one place, you can check multiple boxed and indicate a percentage to each destination.
