• Ash
  Residual material from a fire that 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.
• Treated Wood Waste (TWW)
  In any calendar year that a treated wood waste handler generates more than 10,000 pounds of treated wood waste, the handler shall obtain or maintain an identification number within 30 days of exceeding the weight threshold.  For more information about TWW, visit the Department of Toxic Substances Control. 
  

* 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 mixed material.
• Metal, Appliances, and White Goods
  Metal and appliances (i.e., washers, dryers, refrigerators, stoves) containing metal are 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 to verify 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.
