  • Carbon offsets from organic waste conversion projects

    The Climate Act ion Reserve (the Reserve) has long had a protocol to give credit for the capture and destruction of methane emissions from organic waste in landfills, but they have now opened up the possibility of credits for projects that prevent that waste from entering landfills in the first place. In October 2009, the Reserve adopted the Organic Waste Digestion Project Protocol, covering both ...

  • Los Angeles County WRRF Embraces Codigestion

    Technology to produce food waste slurry key to project implementation - and helps generators comply with California organics recycling mandates. The Sanitation Districts’ JWPCP in Carson (CA) treats an average of 280 million gallons/day of wastewater. One of the two anaerobic digestion tanks above has been used for codigestion, with the second serving as the control. Photos ...

  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • Anaerobic co-digestion of municipal organic wastes and pre-treatment to enhance biogas production from waste

    Co-digestion and pre-treatment have been recognized as effective, low-cost and commercially viable approaches to reduce anaerobic digestion process limitations and improve biogas yields. In our previous batch-scale study, fat, oil, and grease (FOG) was investigated as a suitable potential co-substrate, and thermo-chemical pre-treatment (TCPT) at pH = 10 and 55 °C improved CH4 ...

  • Baseline Projections of Selected Waste Streams

    Abstract Waste represents an enormous loss of resources both in the form of materials and energy. Indeed, quantities of waste can be seen as an indicator of the material efficiency of society. Waste generation is increasing in the European Union, and amounted to about 3.5 tonnes of solid waste per person in 1995 (excluding agricultural waste) 1 Excessive quantities of waste result from: ...

  • Environmental analysis of management systems for organic waste

    Organic waste is generally easily degradable and has a high nutrient content. Thus the risk is large that the handling of such material will generate emissions that affect the environment. New systems have been introduced for managing organic waste fractions from households and industries. These systems are based on source separation and biological treatment, e.g. composting and anaerobic ...

  • 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 ...

  • Fuelling ultra light rail public transport from a Gloucestershire organic waste treatment plant: a feasibility analysis

    Many medium-sized towns and cities face separate problems of traffic congestion and increasing pressure to reduce waste sent to landfill. The intent of the study was to determine whether the utilisation of biohydrogen from organic waste, as a transport fuel, can provide a holistic solution for municipalities to meet renewable energy and waste reduction targets in medium-sized towns. The study ...

  • Remscheid pilot project: evaluation of a large scale trial of utilizing biodegradable waste bags for biowaste collection and treatment

    Separate collection of organic waste may be considered as an integral part of contemporary waste management schemes. In this function it became widely accepted in the last ten years. It pursues the idea of a recycling economy according to the European hierarchy of waste - prevent, reduce, recycle - and is aimed at closing nutrient cycles. Nevertheless, separate collection at source essentially ...

  • Database “organic and mineral residues”

    In the spirit of the material recycling concept in Germany (KrW-/AbfG, 1994), wastes are to be recycled as completely as possible, avoiding any impairment for mankind and the environment. In this connection, avoidance of material burdens by excessive nutrient and pollutant discharge is particularly important in the treatment, recycling and bringing into circulation of waste materials for re-use ...

  • Biochemenergy: a project to turn an urban wastes treatment plant into biorefinery for the production of energy, chemicals and consumer's products with friendly environmental impact

    Urban bio-wastes (UBW) contain soluble bio-organics (SBO) with excellent surfactant properties are proven or expected to perform as bio-based products for use in chemical and environmental technology, in agriculture and in animal husbandry as well as or better than commercial synthetic products. On these basis, UBW are proposed as renewable sources of a wide number of products with potential sale ...

  • Organic waste in circulation -co-operation between university, practice and society in Sweden

    A challenge for the future is to improve recirculation of organic waste, including its contents of nutrients, between urban and agricultural ecosystems. The main reason for developing recirculating systems is to conserve energy and nutrients. The aim is to enable production of high quality and quantity food and feed on a long-term basis, to develop safe and economically feasible systems, to ...

  • Environmental efficiency of composting versus anaerobic digestion of separately collected, organic waste

    Environmental policy in the Netherlands among others aims at closing material cycles and minimising the amount of waste requiring final disposal. In this policy the highest priority is given to the prevention of waste production followed by (in descending order of preference) reuse, incineration with energy recovery and sanitary landfilling. In the implementation of this solid waste policy also ...

  • Perspectives on organic waste recovery relative to composting and anaerobic digestion

    Generally speaking, organic waste renders its self suitable for recovery purposes owing to the nutrient elements it contains and the energy stored in the biochemical bonds of its constituent organic compounds. Both composting and anaerobic digestion (AD) have been used since a long time ago in reclaiming organic material. It seems that the first modern composting process was developed in 1920s in ...

  • Home composting of organic waste - part 2: effect of management practices

    Home composting (HC) can produce safe compost if properly managed, while reducing municipal disposal costs. This project investigated the sanitary and safety impact of HC management (with/without bulking agent, batch/weekly feeding, with/without regular mixing) using the Plastic (P) and Wood (W) bins, the Rotary Drum (RD) and the Ground Pile (GP) filled with equal wet volumes of food waste (FW) ...
