Our specialized equipment and processing meet or exceed Minnesota Pollution Control Agency regulations. ORF managers strive to achieve the Minnesota standard of Process to Further Reduce Pathogens (PFRP), where materials must achieve a temperature of at least 131 degrees for 15 consecutive days. After several months of processing the material and achieving PFRP, the material is screened to produce a uniform compost product. The compost is tested for nutrient content, maturity, percent of organic content, and contaminants.
