Common Hazardous Waste Material
Antifreeze
Antifreeze from residential sources is accepted free of charge through the Hazardous Waste Program. Antifreeze is also accepted for a fee at the Knott Landfill Recycling Center. Call Deschutes Recycling at (541) 388-1910 for pricing.
Asbestos
Asbestos containing material (ACM) is accepted at Knott Landfill by appointment only and Solid Waste Department approval is required at least 24 hours prior to delivery. There are special documentation, handling and packaging requirements for ACM, and requirements vary, depending on the form and condition of the ACM. Advisories and fact sheets on asbestos regulations, safety, handling and other related topics can be found at the DEQ website (www.Oregon.gov/DEQ/).
For non-friable ACM, a Non-Friable Asbestos Disposal Application is required to be submitted and approved prior to scheduling delivery to Knott Landfill. Non-friable ACM is charged at the regular disposal rate but must be delivered separately from other waste and properly packaged. For friable asbestos, a DEQ ASN-4 form and a Special Waste Application must be submitted and approved prior to scheduling delivery to Knott Landfill. The disposal rate for friable ACM is $0.05/pound, with a minimum charge of $100.00.
Auto Batteries
Auto batteries are accepted free of charge at the Knott Landfill Recycling Center, the Hazardous Waste Facility and at all Deschutes County Transfer Stations.
Batteries
Single-use alkaline dry cell batteries (flashlight batteries, etc) can be disposed of in the regular garbage. Modern single-use dry cell batteries are mercury free and do not contain regulated hazardous constituents.
Portable rechargeable batteries (NiCad, Lithium ion from tools, cell phones, cameras, etc) can be recycled at many major tool retailers and rechargeable device retailer. They are also accepted at the Hazardous Waste Facility.
Compact Fluorescent Light Bulbs/Fluorescent Tubes
Fluorescent light bulbs and tubes cannot be disposed of as regular garbage. They are accepted at the Knott Landfill Hazardous Waste Facility.
Fluorescent light bulbs and tubes contain a small amount of mercury sealed within the glass tubing. When a fluorescent bulb breaks in your home, some of this mercury is released as mercury vapor and may pose potential health risks. The broken bulb can continue to release mercury vapor until it is cleaned up and removed from the residence. To minimize exposure to mercury vapor, EPA recommends that residents follow their cleanup and disposal steps described on their webpage: www.epa.gov/cflcleanup.
