The usual exclusions all apply: hazardous waste, liquids, paint, solvents, fuel, and asbestos stay out of any container. San Francisco then adds a rule that no other city on this site has.
Construction and demolition debris from a San Francisco project cannot be landfilled at all. The City's debris recovery law requires that it be recycled or reused, and states plainly that no such debris may be taken to a landfill or an incinerator, or dropped in a trash bin. Penalties run up to $1,000 per day for noncompliance.
That is why mixed loads here go to a registered processing facility rather than a dump. If you separate materials by type instead, clean wood, metal, or concrete can go straight to a reuse or recycling outlet.
Larger permitted projects have their own target. Many have to recycle or reuse at least 65 percent of what they generate, and full demolition jobs have to reach 75 percent, tracked through the City's online reporting system.
Tires, appliances with refrigerant, and mattresses need to be handled separately and billed per piece. When an item is borderline, ask your account manager before it goes in the container.
