Recology Hay Road provides solid waste disposal services to both municipal and commercial customers in the San Francisco Bay Area and the Sacramento Valley. The site primarily serves San Francisco as well as Solano County, specifically the cities of Vacaville and Dixon. In 1964, Recology Hay Road began operation and built its first liner system in 1992. The site is comprised of 640 acres, 256 of which are permitted as a Class II landfill.

Municipal Solid Waste (MSW) – Garbage and non-hazardous refuse. This includes mixed waste materials which are NOT recyclable that are generated by residential, commercial, and institutional customers to be disposed of in
the landfill.
  • Ash
    Residual material from a fire which contains non-hazardous levels of metals and minerals.
  • Contaminated Soil
    Soil (with less than 5% debris) that has contamination with constituents below state and federal hazardous limits. RHR requires any soil suspected of contamination to be tested based on generator knowledge and site history.
  • Hazardous Asbestos*
    Asbestos containing materials are hazardous if they contain 1% or more friable asbestos. Friable asbestos containing material can be easily crumbled or reduced to powder, becoming an airborne hazard.
  • Non-Hazardous Asbestos*
    Asbestos containing materials are non-hazardous if they contain less than 1% friable asbestos. These materials are also non-hazardous if they are non-friable, meaning they cannot be easily crumbled or reduced to powder.

* Hazardous and non-hazardous asbestos containing materials must be properly bagged, labeled, manifested and scheduled prior to disposal.

  • Concrete (Clean)
    Clean concrete that is dry and does not contain other demolition materials (i.e., rebar, wood, inerts). Clean concrete is recycled onsite.
  • Construction and Demolition Debris (C&D)
    Includes, but is not limited to concrete, wood, and drywall, usually found as a mixed material.
  • Metal, Appliances and White Goods
    Metal and appliances (i.e., washers, dryers, refrigerators, stoves) containing metal is recycled. White goods containing Freon, oils, electrical circuits, compressor oils, and mercury switches are accepted for an additional appliance surcharge.
  • Soil (Clean)
    Clean soil and dirt are accepted when the required Clean Soil Certification form is completed by the generator. This signed form must be submitted verifying that the soil is clean and free from contaminants.
  • Tires
    Whole car and truck tires, with rims removed, are recycled for an additional fee.
  • Used Motor Oil
    Non-commercial used vehicle motor oil is collected at the Used Oil Collection Center onsite.
  • Yard Trimmings and Food Scraps
    Organic materials are accepted and converted into earth-friendly, nutrient-rich soil amendments at Jepson Prairie Organics.
  • Wood
    Unpainted lumber, pallets and scrap wood are all recycled onsite. If the wood is mixed with non-wood materials, it is considered MSW and will be directed to the landfill.

Unacceptable materials include but are not limited to liquid waste, paint, household hazardous waste (HHW), electronic waste, batteries, fluorescent tubes and bulbs. HHW material may be dropped off at: 855½ Davis Street in Vacaville. Open every Saturday from 9 am – 3 pm (excluding holidays). Additional HHW information can be found at Vacaville Recycling.

NEW! Starting January 1, 2021, Recology will no longer accept treated wood waste for disposal.

Changes in State law have banned the disposal of treated wood in regular solid waste landfills and will impose significant new requirements on anyone who uses, stores, transports, and disposes of treated wood. If treated wood enters Recology facilities after December 31, 2020, we will reject it and require that you take it away. There will be no exceptions.

Treated wood is any wood that has been treated with a chemical preservative to protect the wood against attacks from insects, microorganisms, or fungi. It is typically used in outdoor applications such as fences, decks, stairways, etc.

For questions about responsible disposal of treated wood waste, contact your local Environmental Health Department or the California Department of Toxic Substances Control.  Visit or email
