Since February of 1995, WORC has raised compost facility operator technical knowledge and sound operating techniques, through the annual Compost Facility Operator Training. WORC also provided this curriculum to the US Composting Council – it’s the model all other US trainings are based on.

The training is 5 full days at the Washington State University Puyallup Research and Extension Center. The current curriculum consists of classroom training, hands on interactive sessions, field trips, and a written examination. Topics covered include:

  • Compost Use in Agriculture and Horticulture

  • Biology of the Compost Pile

  • Feedstocks

  • Feedstock Recovery and Preparation

  • Regulations

  • Odor Management and Response

  • Sampling and Testing

  • Compost Quality

  • Compost Facility Management
