Most household and construction debris can go in your container. California's hazardous waste rules and the landfill's own list set the limits.
Hazardous waste, liquids, paint, solvents, fuel, and asbestos can't go in a standard dumpster. CalRecycle also bans many common items from the trash, including batteries, fluorescent tubes, electronics, and tires, which are banned to prevent mosquito breeding and tire fires. Its list of banned items explains where each one should go.
Appliances with Freon and tires are charged by the piece at the landfill, so mention them when you book. Mattresses aren't banned from the trash in California, but they're handled through a separate recycling program.
A household hazardous waste drop-off at the landfill is open to residents on Saturday mornings, from 9 a.m. to 1 p.m.
If something on your list isn't covered here, ask your account manager before it goes in.
