Hazardous material stays out in every form: paint, solvents, fuel, used motor oil, pesticides, pool chemicals, part-used aerosols and batteries. Liquids are out, and so are pressurized cylinders, asbestos and sharps.
The receiving facility adds its own charges for items it treats as unacceptable or difficult to manage, which is the practical reason to keep those things separate rather than hoping they go through unnoticed.
Tires, appliances, electronics, lead-acid batteries and motor vehicle fluids and filters all sit outside Minnesota's ordinary trash stream, which means each one is handled, priced and routed on its own. Name them when you book and they get sent to the right place.
Yard waste, tree waste and ash are also treated as separate streams in Maplewood's own code, so brush and branches do not ride along in a mixed container.
Ask your account manager about anything unusual before it is loaded, especially on a job that mixes demolition material with household contents, because that mix is what moves the whole load into the designated trash stream.
