Ordinary building and cleanout debris is welcome. The limits come from California law and from Dublin's own sorting requirements.
California has kept organics out of landfills since 2022. Food scraps, food-soiled paper, cardboard, and yard trimmings all have to go to composting or recycling instead of a disposal load, and Alameda County enforces that locally.
Electronics and hazardous material never belong in the garbage, the compost, or the recycling. That covers batteries, paint, solvents, chemicals, motor oil, fuel, pesticides, and asbestos. Alameda County residents can take hazardous waste to any of four county facilities for free, without an appointment, and leftover paint is accepted there too.
Demolition work carries an extra step here. Anyone taking down a building in Dublin has to complete a screening form for older chemical residues in the building materials and file it with the demolition permit, so that paperwork should be sorted before the container arrives.
If a material sits in a gray area, check with your account manager before it goes in the container.
