Composting Facilities

Registered compost facilities in Ohio. Non-residential facilities are required to register if they are greater than 500 square feet in size.


This map shows the locations of compost facilities in Ohio. Ohio law defines composting as a method of solid waste disposal using controlled biological decomposition. Composting activities occurring at a residence and those activities using less than 500 square feet at a non-residential location are not subject to Ohio’s composting regulations. 

The solid waste composting regulations require that a facility obtain a registration, license and/or permit, as applicable. Other requirements established by the program include: types of wastes that can be accepted for composting; operational requirements of the facility; and testing requirements for the finished product prior to distribution.

Solid waste composting facilities that fall into the following categories are regulated by the Division of Materials and Waste Management (DMWM):

  • Class I: Mixed solid waste
  • Class II: Yard waste, agricultural plant materials, animal waste, dead animals, raw rendering material and food scraps
  • Class III: Yard waste, agricultural plant materials, animal waste, and dead animals, raw rendering material
  • Class IV: Yard waste and agricultural plant materials
