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.
Composting facilities are classified according to the feedstocks they are allowed to accept and are required to obtain a registration, license and/or permit from Ohio EPA, as applicable. The classifications are:
- 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
Other requirements established by the program include: operational requirements; recordkeeping; and testing requirements for compost product prior to distribution.
