Most building and household debris is accepted. The limits come from the city's refusal rule and from what the receiving landfill will take.
Farmers Branch allows collection to be delayed or denied where a container holds anything corrosive, flammable, explosive, medical, toxic or hazardous, until the material is taken out. In practice that means paint, solvents, fuel, pool chemicals, pressurized cylinders and medical sharps have to stay out of the container from the start.
The landfill side is simpler. Restricted materials may not be disposed of in any part of the site, so hazardous waste, liquids and free liquids in drums are all out. Appliances are accepted with refrigerants removed, and furniture, municipal waste, commercial waste, grass clippings and brush are all taken.
Asbestos belongs in neither place. On a Farmers Branch house built before the mid-1980s, pipe insulation, floor tile mastic and some textured ceilings are worth testing before anything is torn out.
Tires and electronics have their own routes. The public landfill limits tire quantities and takes electronics only from its own city's residents, so a pile of either needs arranging separately rather than hiding in a container.
If you are unsure about an item, ask your account manager before it goes in. One restricted item can hold a whole load at the gate.
