Compost Professionals Training

The Compost Professionals Training, modeled after WORC’s successful Compost Facility Operator Training (CFOT) will be a 3-day event designed for professionals interested in advancing their knowledge of compost science, technology, economics, regulations, and markets. We encourage those employed with local health jurisdictions, air agencies, public works departments, state agencies, conservation districts, compost facilities, and technical service providers to consider attending. This training will feature presentations from subject matter experts, facilitated group discussions, workshops, and compost facility tours.
