A composting facility is substantially different from a backyard compost pile. Large-scale compost facilities closely monitor and have practices in place to ensure conditions are ideal for composting. Waste entering the facility and finished compost are tested so finished compost is safe and the environment is protected.
Rules and regulations
To operate a compost facility in Minnesota, you must have a solid waste facility permit. The application form, instructions, and checklists are available from MPCA's Solid Waste Permit Application webpage.
Yard waste facilities
Yard waste includes garden waste, leaves, lawn clippings, weeds, shrub and tree waste, and pruning. These materials have been banned from Minnesota landfills since 1992. Owners or operators of a new yard waste facility need to fill out a permit-by-rule notification form and are responsible for following Minnesota's compost rules.

Home backyard compost bins are not regulated by the MPCA. Check with your community about local ordinances or requirements.
Establishing a source-separated organics dropsite
Collecting compostable material such as food scraps and non-recyclable paper is becoming more common. Some communities offer curbside organics collection or drop-off locations for residents. A growing number of businesses, organizations, and schools are also participating in organics collection.
To establish a dropsite to collect organics that will be transferred to a commercial composting site, complete the notification form:
