Ohio law defines composting as a method of solid waste disposal using controlled biological decomposition. As such, composting is regulated by the Division of Materials and Waste Management.
Solid waste composting facilities fall into the following categories:
- Class I – mixed solid waste
- Class II – source-separated yard waste, agricultural waste, animal waste, and food scraps
- Class III – source-separated yard waste, agricultural waste, and animal waste
- Class IV – source separated yard waste
The solid waste composting regulations require that a facility obtains 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.
Composting activities occurring at a residence and those activities using less than 300 square feet at a non-residential location are not subject to Ohio’s composting regulations. For more information about Ohio’s Composting Program, please see the menu below.
