Commercial composting

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.

Compost rules and regulations

  1. Complete and submit the permit-by rule (PBR) permit application form below.
