OCWR receives seal of assurance from US Composting Council

The certification signifies the California waste agency’s compost offers the highest standards of compost quality.


OC Waste & Recycling (OCWR), based in Orange County, California, has received the U.S. Composting Council’s “Seal of Testing Assurance” at the Frank R. Bowerman landfill’s Bee Canyon Greenery, as well as the Prima Deshecha landfill’s Capistrano Greenery.

This certification signifies that OCWR’s compost offers the highest compost quality standards, meeting all federal, state and local regulations and permitting.

“OC Waste & Recycling is honored to receive the composting seal of approval,” says Tom Koutroulis, director of OCWR. “The designated certification assures residents that our ingredients and production processes will provide nutritious compost for yards and gardens to ultimately increase plant health.”

OCWR currently operates greeneries in Irvine and San Juan Capistrano and anticipates opening a third at Olinda Alpha Landfill in Brea in early 2023. The greeneries use open windrow composting technology but will evolve to covered aerated static piles (CASP), and on to integrating multiple types of feedstocks.

The use of compost generates healthy soils, adding nutrients for plant growth as well as improving water retention and quality, says OCWR. The solid waste department’s compost is created from green waste collected from residential homes and businesses.
