  • Bio-fuels- Anaerobic digestion

    Anaerobic digestion is a series of processes in which micro organisms break down biodegradable material in the absence of oxygen. It is widely used to treat wastewater sludges and organic (agricultural) wastes.  As part of an integrated waste management system, anaerobic digestion reduces the emission of gas into the atmosphere. Anaerobic digestion is a renewable energy source because the ...

  • Financing an anaerobic digester

    LENDERS are generally well disposed to projects that diversify revenues while lowering costs and mitigating risks. Add a ready source of equity and you are well on the way toward financing a project that is a win-win proposition for the lender and the project developer. Such is the case with the anaerobic digester project at Geerlings Hillside Farm (GHF). The Geerlings's 8,000-head hog farm is ...

  • 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. ...

  • Anaerobic Digestion Of Compostable Bags

    Dry anaerobic digestion facility in Luxembourg successfully treats mixed yard and food waste collected in compostable plastic bags. Preprocessing, anaerobic digestion and composting operations are enclosed at the Syndicat Minett-Kompost facility. While the value of compostable plastic bags to increase participation in residential source separated organics (SSO) programs is well-recognized, much ...

  • Latest Progress in Anaerobic Digestion

    Compared to countries like Germany and Denmark, the United States and Canada have a long way to go in creating the fundamental policy incentives and regulatory mandates that will encourage market development for anaerobic digestion (AD). Someone recently asked me how many years it would take to deploy AD systems on farms in North America that are large enough to economically use them. Given ...

  • Anaerobic Digestion Reduces Microplastics in Sludge

    Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and personal care products, including toothpaste, cosmetics, and beauty scrubs. They also include fragments from the breakdown of anything in our ...

  • Energy Recovery from Residual Waste by Means of Anaerobic Digestion Technologies

    ABSTRACT Anaerobic digestion (AD) is a natural process, spontaneously taking place in natural surroundings, such as marshes,bogs, paddies, or in cesspits, landfills, and dedicated digesters, used for the conversion of organic waste into a rich gas. Typical AD substrates are: manure, sewage sludge, high BOD wastewater, and – more recently - the organic fraction of Municipal Solid Waste (MSW), ...

  • 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 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 ...

  • 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 ...

  • 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 at Dairy Farms

    The need to upgrade dairy waste management practices to overcome pollution problems is leading more farmers to seek solutions with anaerobic digestion technology. Two recent examples of this trend are underway at California sites. The Cal Poly Dairy is located adjacent to the California Polytechnic State University campus in San Luis Obispo. The dairy milks 180 cows with a total population of ...

  • High solids anaerobic digestion of pfmsw using novel anaerobic reactors

    In the last decade efforts have been made to control anaerobic digestion of the putrescible fraction of municipal solid waste (PFMSW) in engineered reactors, than to allow for 'free' digestion in landfill sites. Such a process achieves enhanced treatment efficiency in significantly reduced retention times (from years down to days) and completes energy recovery from waste, without biogas emissions ...
