  • 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 ...

    Contracting for turnkey AD provider Monsal, Kirk Environmental constructed the anaerobic digester tank on the plant capable of processing up to 30,000 tonnes of food waste every year. Kirk Environmental constructed the 4000m3 Glass Coated Steel Digestion Tank complete with glass coated Roof. The plant is the largest food waste digestion facility in the East Anglian region and is the first for ...

  • 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 ...


  • Evaluating Food Digestion Effluent For Landscape Use

    Over the last year, Loyola Marymount University (LMU) has installed and studied a food waste diversion technology that converts raw food waste into a liquid effluent that is disposed through the sewer system. As an urban university located in West Los Angeles, California, LMU faces two major barriers with respect to composting food waste: on-campus space constraints and long distances to off-site ...

  • 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 Digest

    Wilsonville, Oregon: Food Scraps Digester Proposed An anaerobic digester with capacity to process 50,000 to 70,000 tons/year of commercial food waste is being proposed in Wilsonville by Sustainable Organics Recycling Technology (SORT) Bioenergy. Wilsonville is in the Portland metro area. Currently, a portion of commercial food scraps from the metro area are hauled to the ...

  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • 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 ...

  • Zero food waste – possibility or pipedream?

    Many people would argue that the UK’s target to halve edible food waste by 2020 is difficult to achieve. Perhaps even more would deem the country’s ultimate zero food waste to landfill vision, simply a pipedream. But what factors contribute to food waste in the UK and to what extent is progress being made? Paul Featherstone, group director of specialist surplus food recycler SugaRich, ...

  • 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. In some instances, the projects being proposed and constructed only include anaerobic digester operations. In others, there is a combination of digestion with back-end ...

  • Waste treatment Wernsing Anaerobic Digestion Plant (Germany)

    Wernsing biogas plant Addrup The Wernsing biogas plant was one of the first biogas weser-ems plants to treat waste from food industry since its commission in 2001. Up to 200 tonnes of white cabbage and potatoes waste are used as main input material per day. In addition to the biogas plant, the facilities owned by the Wernsing group include a waste water treatment plant to treat the sewage ...

  • Renewable energy from food wastes

    Food waste is an untapped energy source that mostly ends up rotting in landfills, thereby releasing greenhouse gases into the atmosphere. Food waste is difficult to treat or recycle since it contains high levels of sodium salt and moisture, and is mixed with other waste during collection. Major generators of food wastes include hotels, restaurants, supermarkets, residential blocks, cafeterias, ...

  • Fate of pathogen indicators in a domestic blend of food waste and wastewater through a two-stage anaerobic digestion system

    Anaerobic digestion is a viable on-site treatment technology for rich organic waste streams such as food waste and blackwater. In contrast to large-scale municipal wastewater treatment plants which are typically located away from the community, the effluent from any type of on-site system is a potential pathogenic hazard because of the intimacy of the system to the community. The native ...

  • Examination of food waste co-digestion to manage the peak in energy demand at wastewater treatment plants

    Many digesters in Germany are not operated at full capacity; this offers the opportunity for co-digestion. Within this research the potentials and limits of a flexible and adapted sludge treatment are examined with a focus on the digestion process with added food waste as co-substrate. In parallel, energy data from a municipal wastewater treatment plant (WWTP) are analysed and lab-scale ...
