Everyday household and construction debris is welcome. The limits here are set by what Kitsap County's transfer station will take and by Washington's rules on dangerous waste.
The County keeps a specific list out of general garbage: lithium-ion and other rechargeable batteries, flammable waste, hazardous waste, paint, pressurized tanks, liquids, medications, vehicles and vehicle parts, large appliances, tires, and sewage. Several more materials need pre-approval before they arrive, including asbestos, creosote-treated lumber, soils, and coal ash.
Washington handles batteries, light bulbs and tubes, and mercury-containing items such as thermostats and old automotive switches as universal waste. That means they must be labelled, kept from breaking, and sent to a facility that can take them, not thrown in with the trash. Households can find drop-off options through the state's recycling line instead.
Asbestos deserves its own paragraph in a town full of pre-1980 houses. The County takes asbestos waste by appointment only, Tuesday through Thursday, and nothing can be delivered until the appointment is confirmed. Material has to arrive wet, double-bagged in heavy plastic with each bag under 50 pounds and labelled, and every load needs a shipment report filled out in ink. Asphalt shingles are the exception and need no wrapping or label.
If your project might turn up asbestos in flooring, pipe wrap, siding, or textured ceilings, say so when you book. Your account manager will set up the right handling instead of letting a load get turned away.
