  • 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 ...

  • 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 ...

  • 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 ...

  • Evaluating the potential of an electronic nose for detecting the onset of anaerobic conditions during composting

    Most bad odours in composting plants are formed under anaerobic conditions and often they could be avoided if detected early enough. In this project an electronic nose was used to evaluate the odours produced during a composting process at bench scale. The electronic nose consists of an array of electronic chemical sensors with partial specificity and an appropriate pattern recognition system ...

  • 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 ...

  • 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 ...

  • Anaerobic procedures (fermentation)

    Anaerobic technology is particularly well suited for the utilisation of organic industrial refuse with a high water content as well as for the organic part of bio-waste. A crucial factor for the increasing acceptance of anaerobic waste treatment is the fact that - in contrast to composting - the energy (digested gas) which is released during fermentation can be collected and used and enables ...

  • Plastics Separation In Compost

    Operators say their number one contamination problem is plastic small, large and in-between - in the compost feedstock and thus in the end product. New study and equipment offer some excellent solutions. An air separation unit from Hawker Corp. is attached to the outfeed conveyor of a screen. Plastic is collected in a tube sock (inset) attached to the fan assembly. PRESSURE in Europe to increase ...

  • Effect of temperature on composting residual Organic Fraction of Municipal Solid Waste (OFMSW) after anaerobic digestion

    Aerobic composting is generally considered as a necessary post-treatment for residual solids after anaerobic digestion. This study aimed to determine the effects of temperature on biodegradation, microbial population density in composting residual OFMSW after anaerobic digestion. Four composting runs at different set temperatures were conducted. The rate of ...

  • Effects of the anaerobic biowaste treatment processes Management on the digestate quality (residues from Digestion/compost, process water/wastewater)

    Regarding the municipally-collected biowaste amount in Germany, a quantity of 90 - 100 kg/ per annum per citizen is registered (Gallenkemper and Doedens, 1994). That results in an annual biowaste amount of 6.3 to 7 million tons in the Federal Republic of Germany (FRG), whereby also sewage sludges and biogenic, industrial wastes are added. According to Hochrein (1994) about 3 million tons of ...

  • Perspectives of composting and anaerobic digestion technologies for the treatment of organic fraction of municipal solid waste in Europe and Asia

    The development and implementation level of composting and anaerobic digestion technologies for municipal biowaste management in Europe and Asia are different in many aspects. The progress of these technologies generally depends on the lifestyle, waste generation rate, waste characteristics, awareness level, acceptability, market value and other economic factors. In Europe, regulatory directives ...

  • Voluntary compost quality assurance based on the new Austrian compost decree

    The Austrian national waste management plan has to consider a total of 3.7 million MG of communal and commercial organic and other 28 million MG of organic by-products and residues from f. e. waste water treatment, the agricultural sector, wood processing, as well as mineral residues, can be used as co-feedstock or additives for bioprocessing. According to sustainable waste management strategies ...

  • Growing the Composting and Organics Recycling Industry

    ORGANICS RECYCLING is a resource management system with a goal to utilize residuals to their greatest extent. For farmers, gardeners and landscapers, it means creating a compost product that economically and efficiently builds organic matter into soils and grows flourishing crops. For economic developers and ...

  • Odor Control Advances at Composting Facility

    The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...

  • A new Technology for Composting: Suction Aeration for Opening Composting Works

    Cost-efficient solution for smell emission reduction The enormous waste quantities that are produced day by day are one of the most difficult problems for the economy as such, for cities and communities and for private households. Storage capacities for waste are scarce everywhere. Therefore solutions of all kinds that reduce waste quantities or recycle waste materials to be reused in the ...

  • Temperature–dependent polylactic acid (PLA) anaerobic biodegradability

    Polylactic acid (PLA) biodegradability is mostly claimed according to PLA biodegradation behaviour under aerobic composting conditions. However, waste materials containing PLA are frequently disposed of in municipal landfills, which are operated anaerobically. PLA anaerobic sludge digestion results are acquired to elucidate effects of the degrading temperature on PLA biodegradation. When the ...
