Type 1/Treatment & ProcessingType 2Type 3Type 4WWTP

  • Note: Each permitted facility has a unique permit, please check with facility of interest to see if they can and are able to process a certain type of organic waste.  This map excludes the NCDEQ DWM Solid Waste Section (SWS) “permitted demonstration” composting facilities.
  • Facility Types and Feedstocks
    • Treatment & Processing (T&P): typically T&P sites only grind wood waste, however there are a few that compost.
    • Type 1: may receive yard and garden waste, silvicultural waste, untreated and unpainted wood waste.
    • Type 2: may receive Type 1 feedstocks, pre-consumer meat-free food processing waste, vegetative agricultural waste, source separated paper or other source separated specialty wastes, which are low in pathogens and physical contaminants.
    • Type 3: may receive Type 1 and 2 feedstocks, manures and other agricultural waste, meat, post consumer-source separated food wastes and other source separated specialty wastes that are relatively low in physical contaminants but may have high levels of pathogens.
    • Type 4: may receive Type 1, 2, and 3 feedstocks, mixed municipal solid waste, post collection separated or processed waste, industrial solid waste, non-solid waste sludges functioning as a nutrient source or other similar compostable organic wastes.
    • WWTP: for the most part, these are wastewater treatment facilities that compost biosolids and yard waste only.
    • Note: because a facility is permitted as a certain “type” it does not necessarily mean that they can accept any material as per the SWS rules, so please check with each one before assuming that they will be able to accept your organic waste.
  • Facility Sizes
    • Small: may receive less than 1,000 cubic yards (CY) of material for composting per quarter and/or occupy less than 2 acres of land, and it may process or store less than 6,000 cy of material per quarter.
    • Large: may receive 1,000 CY or more of material for composting per quarter and/or occupy 2 acres or more of land, and it may process or store more than 6,000 cy of material per quarter.
