  • Building Farm And Food Scrap Digesters

    In the past several weeks, we received invitations to two ribbon cuttings for newly installed farm-based digesters — one at a dairy farm in western Massachusetts and another at a swine operation in North Carolina. We also received a press release from the University of California, Davis, about its new food scraps digester on campus. And then there were a few new projects that we had been ...

  • Two-phase anaerobic co-digestion of food waste and sewage sludge

    The feasibility and performance of food waste and sewage sludge co-digestion were investigated to gain insight into their resource utilization. In this study, two-phase anaerobic digestion (TPAD) was operated under a total solids mixing ratio of 1:1 and different sludge retention times (SRTs). Results show that an acidogenic reactor with a 5-day SRT obtained the highest acidification efficiency, ...

  • Climate change impacts of food waste diversion to anaerobic digesters

    Treating food waste (FW) by anaerobic digestion to recover biogas and biofertiliser is a fantastic opportunity. The biogas is renewable, base-load, non-fossil energy. Using the digestate on land as biofertiliser completes nutrient cycles and conserves soil organic matter. The Part-503 rules protect health and the environment. Existing sludge digesters can be ‘turbo-charged’ by retrofitting ...

  • What’s next for food waste?

    With the target to halve edible food waste by 2020 drawing ever closer, a growing number of food manufacturers and retailers are improving their waste prevention strategies. But when ‘waste’ is inevitable, what then? Paul Featherstone, group director of SugaRich, investigates the extent to which such organisations are saying ‘no’ to landfill, before considering what ...

  • Anaerobic Co-Digestion of a Single Source Oily Waste and High Strength Pet Food Wastewater: A Study of Failure and Revival of a Full Scale Digester

    ABSTRACTThis paper focuses on the revival of a formerly failed digester of 1800 m3 volume. The most obvious cause of failure was identified to be due to capping caused by foam and scum, as result of attempting to treat oil rich, high strength wastewater. The revival was affected by implementing co-digestion in a 3-step remedial procedure. Though in the typical sense, codigestion involves separate ...

  • Digester Developers Target Mixed Organic Waste Streams

     emerging group of commercial companies see a viable business opportunity in North America around building, owning and operating larger scale anaerobic digestion (AD) facilities to process mixed organic waste streams.
