Organic Waste Material Treatment

Tech ID: 27429 / UC Case 2006-240-0


A researcher at the University of California, Davis has developed a method for treating organic waste materials.

Full Description

A researcher at the University of California, Davis has developed a multi-stage process and system for treating organic waste materials. This process produces a high-quality compost derived from food waste and other organic materials while avoiding the environmental problems of traditional composting methods such as emissions of odors, volatile organic compounds and other noxious gases. The combination of anaerobic hydrolysis, anaerobic digestion, and aerobic composting yields biogas as fuel and a stable organic material usable as a soil amendment.


  • Anaerobic digestion and composting
  • Waste streams having organic content


  • Uses low-cost hydrolysis vessels
  • Inexpensively and rapidly breaks down the organic waste
  • Reduction of emissions of noxious gases and volatile organic compounds
  • Lower energy requirements associated with the composting process
  • Can be used with a wide range of organic waste materials (agricultural wastes, biosolids sludge, cannery wastes, green and wood wastes, manures, municipal solid waste (MSW)
  • Allow scale-up to meet various waste treatment requirements
