Compost comes from decaying organic matter, like food and yard waste. Finished compost looks and feels like fresh potting soil, which when added to the soil helps plants grow, reduces erosion, and conserves water.
Compost is regulated in part, by the Minnesota Pollution Control Agency.
The photos below show a few steps in the commercial compost processing.
The MPCA has regulated the composting of community yard waste and solid waste materials since 1988. The Minnesota Legislature mandated the statewide source separation of yard waste in 1992 and banned it from being landfilled or incinerated. As a result, over 100 yard waste compost sites have been established.
The MPCA Yard Waste Compost Permit Program requires applicants to:
- Complete and submit the permit-by rule (PBR) permit application form below.
- Operate in compliance with the yard waste rules in Minn. Rules 7035.2836.
- Complete and submit an annual report below.
The MPCA does not regulate backyard composting. Learn how you can Start composting in your backyard.

In addition to the MPCA, other Minnesota state agencies have rules concerning composting:
- Minnesota Board of Animal Health regulates composting of farm animal mortalities. See Minn. Rules 1719.4000
- Minnesota Department of Transportation (MnDOT) has specifications for the quality and use of compost for its turf establishment projects. See MnDOT Standard and Specification for Construction, specification 3890.
- Minnesota Department of Agriculture regulates the labeling and fees of compost sold as fertilizer. See Minn. Rules 1510.0430 - 1510.0434
The current list of PBR yard waste compost sites are listed at the following link below. Individual counties can provide the dates and operating hours of each site.
