Solid-State Food-Waste Biogas Technology

Compact Food Waste Biogas Plant

Anaerobic digestion, or bio-methanation, of food waste is a recommended sustainable method for treating food waste. Conventional biogas plants have inherent limitations, including large footprints, freshwater consumption, low biogas yield, and foul-smelling discharge slurry that can lead to vector breeding. A novel solid-state bio-methanation system for food waste has been developed as an improved alternative to existing biogas plants, particularly suitable for corporations and municipal areas. This innovative technology addresses the limitations of conventional systems while providing an efficient solution for food waste management. The solid-state bio-methanation system offers numerous advantages, making it a promising option for various food waste-generating establishments.

  • Advantages :
    • Compact and Versatile Design: The system features a compact size, scalability to accommodate more food waste, and potential portability even for large units, making it suitable for diverse settings.
    • Efficient Resource Management: This technology eliminates freshwater consumption, can process any type of food waste, and produces less slurry output that is highly stable and usable as manure
    • Enhanced Biogas Production: The system yields more biogas with higher methane content, approximately 200 liters per kilogram of food waste, surpassing conventional biogas plant performance.
    • Environmental and Health Benefits: By eliminating vector problems and reducing odor issues, the solid-state bio-methanation system contributes to improved sanitation and public health in waste management areas.
  • Commerical Status : Already Commercialised
  • Technology Readiness Level : Technology Integrated Industrial Application : Hotels, canteens, and large catering
  • Research Area :
  • Description :The newly developed anaerobic digester offers a complete solution system for biodegradable household wastes. It converts household and other inorganic waste from hotels, canteens, and large catering areas into compost manure and generates methane-rich biogas from biomass wastes at the source of generation.
