  • Facilitating Food Waste Digestion

    Increasing volumes of commercial food waste, much of it contaminated or packaged, led digestion facility in South San Francisco to install a depackaging unit. South San Francisco Scavenger Company (SSFSC) and Blue Line Transfer, the facility that handles SSFSC’s recycling and disposal, started up its dry anaerobic digester (AD) in late 2014. Situated at Blue Line’s 11-acre site in ...

  • Addressing food waste through anaerobic digestion

    Food waste continues to be a problem worldwide, even with more and more attention being paid to reducing spoilage and to salvaging edible foods for redistribution or reuse. One approach to the problem is diverting inedible organic matter from landfills and treating it with anaerobic digestion, which has the side effect of capturing energy. The amount of food wasted worldwide was 2.3 billion ...

  • 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, ...

  • 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 ...

  • 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 ...

  • On-Site Food Waste Pretreatment

    Guide to equipment and systems for businesses, institutions and venues that manage food waste on-site. Businesses, institutions and venues that generate large volumes of food waste have an increasing number of options to manage this organics stream, starting with tools and knowledge to prevent and reduce what is generated in the first place, followed by donation of excess and prepared ...

  • 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 ...

  • Anaerobic Digest

    Washington, DC: NOSB Considers Digestate Use Petition The National Organic Standards Board (NOSB) of the U.S. Department of Agriculture (USDA) has agreed to consider a petition from Cenergy USA, the makers of Magic Dirt™, to allow use of digestate from anaerobic digestion plants in organic agriculture. Magic Dirt is made from digested dairy manure fibers. The soil amendment products ...

  • 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 ...

  • 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, ...

  • Case study - Waste food to energy

    BIONOVA-GLOSFUME PROCESS. A patented BIONOVA process which converts food waste into energy was awarded the 2010 Food Processing award. During 2010 Jamie Oliver identified the benefits from converting waste food to energy. This greatly reduces the cost of landfill with the benefit of minimising the cost of hot water for the kitchens. The Glosfume Biomass Filter offers ultra low ...

  • 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, ...

  • EU working to end food waste

    With food waste across Europe reaching almost 88 million tons each year, at a cost of 143 billion euros, legislators are keen to put an end to such losses and waste. The European Commission has launched the European Union Platform on Food Losses and Food Waste to tackle these issues; the first meeting was on November 29, 2016. Vytenis Andriukaitis, the Lithuanian commissioner for health and ...

  • 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 ...

  • 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 ...

  • Anaerobic treatment of food waste in pilot scale

    For this work, a pilot scale anaerobic digester was used to assess the treatability of food waste from a canteen. The digester was operated for 720 days, and its efficiency in removing organic matter and suspended solids as well as producing biogas were assessed. At the beginning of operation, the digester failed and alkalinity buffering was required until stabilization. A maximum chemical ...

  • Urban Food Waste generation: challenges and opportunities

    Greater economic activity and a wider economic gap between rural and urban areas is leading to accelerated urbanisation and the generation of 35% more Urban Food Waste (UFW) from 2007 to 2025. Besides landfilling, this paper examines the advantages of introducing onsite composting and anaerobic digestion for the environmental recycling of UFW and the lowering of handling cost. For Asia and ...
