  • Startup of Anaerobic Mesophilic Digesters

    Many operators have started up mesophilic digesters, but everyone has differing stories and experiences. This paper is a combination of the startup of several mesophilic anaerobic digesters, with very low seeding to fully seeded conditions. Upper Occoquan Sewage Authority (UOSA) operates the Millard H. Robbins Water Reclamation Plant. UOSA started three anaerobic digesters between August 2000 and ...

  • Anaerobic Digestion—What Are the Economics?

    Although solid waste AD facilities are just starting to emerge, haulers and their customers may see some benefits if the development trend continues. A Pro Forma Model objective can be constructed for strategic planning of an anaerobic digestion facility. Anaerobic digestion (AD) of food wastes in the U.S. is a developing market that is poised for continued growth in many regions. ...

  • Anaerobic digestion in the United Kingdom

    Anaerobic digestion (AD) has been used to treat sewage sludge by the United Kingdom’s (UK) water industry for over 100 years. More recent years have seen a revolution as AD has swiftly expanded into agricultural feedstocks and food waste. Data from the Waste Resource and Action Programme (WRAP) shows that in the past year alone, there has been a 46 percent growth in the size of the sector. ...

  • CH#1138 - Anaerobic Digesters

    Waste Type: Fats, oils and grease (FOG) in Anaerobic Digesters Problem: FOG waste poses a challenge for most municipal wastewater collection systems and treatment plants. Although fats, oils and grease will biodegrade in an anaerobic digester, high concentrations will tend to 'mat' on the sludge surface, lowering digestion efficiency. This Midwestern municipal facility was no different. The 1.5 ...

  • Anaerobic digestion of aliphatic polyesters

    Anaerobic processes for the treatment of plastic materials waste represent versatile and effective approach in environmental protection and solid waste management. In this work, anaerobic biodegradability of model aliphatic polyesters, poly(L-lactic acid) (PLA), and poly(ɛ-caprolactone) (PCL), in the form of powder and melt-pressed films with varying molar mass, was studied. Biogas production ...

  • Advances in Thermophilic Anaerobic Digestion

    ABSTRACTSignificant advances have been made in the knowledge base and practical options for improving thermophilic anaerobic digestion over the past 10 to 15 years. Today, more options exist that promise to enhance the degree of stabilization achieved and finished product quality in new and retrofitted existing processes. In parallel, the body of knowledge regarding pathogen inactivation in these ...

  • Golf and a Small Anaerobic Digester

    Golf course associations and golf clubs around the world are looking at ways to improve the sport’s environmental criteria.  Sustainable developments and low carbon footprint operations are the name of the game.  As golf courses use fertiliser for the courses, power for the maintenance machinery, and power for the golf carts, there are many areas where sustainability of the sport ...

  • Managing Compostable Bags At Anaerobic Digestion Plants

    The highest and best use for treating residential food waste is through source separation, sending organics first to anaerobic digestion (to capture energy), followed by aerobic composting (to return nutrients to the soil). Sending food waste to anaerobic digestion (AD) facilities requires appropriate tools and planning for capturing high volumes of material with low contamination. Compostable ...

  • 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 ...

  • Evaluation of anaerobic digestate as a substrate for vermicomposting

    Vermicomposting is an established process to convert organic wastes into vermicastings suitable for plant growth. This research investigated the vermicomposting of anaerobic digestate with four different ratios of sawdust as a bulking material, for 75 days. The optimum proportion of anaerobic digestate to sawdust was identified as 70:30 based on worm growth and reproduction. Vermicomposting ...

  • Anaerobic digestion in Sweden - status and experiences

    The implementation of biogas technology has in general increased in Sweden over the last 4-5 years. The main reason for this development is the effort to replace landfilling of nutrient-rich, wet organic waste with sustainable alternatives. In accordance with the EU directive on landfilling, a tax on putting organic waste into landfills will be introduced the 1st of January 2000, together with a ...
