  • Biowaste collection in residential areas with dense population

    Because of legal regulations in Germany the biological treatment of organic residues is becoming more and more important. Following the regulations of the Waste Avoidance, Recycling and Disposal Act (KrW-/AbfG) and the TASi (Technical Data Sheet of Urban Wastes) biowaste has to be collected and treated separately. The waste management objective of the separate collection and biological treatment ...

  • 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 ...

  • Separating micropollutants from biowastes using anaerobic treatment facilities

    Recycling of municipal organic wastes from separate collection systems becomes more and more important in the Federal Republic of Germany. Experiences gathered during the last few years indicate that the recovery potential of waste and biosolids strongly depends on quality of the produced composts or their pollutant load. This means that only really low polluted composts will be competitive in ...

  • Effects of biowaste compost on vegetative growth, Yield and fruit quality of james grieve apples

    In Lower Austria 69 agricultural composting plants are in operation in addition to municipal and commercial composting plants. The agricultural composting plants process separately collected organic household waste as contractual partners for the neighbouring municipalities. The compost produced is used to a large extent on the agricultural fields of the plants' owners. In order to improve the ...

  • 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 ...

  • 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 ...

  • Source separation trends in the UK

    THE past 15 years have seen significant investment and development of the biowaste collection and treatment industry in the United Kingdom (UK), which has gone from virtually zero to an industry worth over £160 million (264.6 million USD). Driving this investment have been a number of regulatory and fiscal measures such as the first set of Landfill Directive targets due in 2010. Since 1999, the ...

  • Determination of sand content in digestate

    The biological treatment of separate collected waste becomes more and more important. The composting is still the dominant method of treating this waste, but the anaerobic alternative, the anaerobic digestion, plays an increasing part. In Germany already 15% of the whole capacity of biological treatment plants for separate collected biowaste are of anaerobic digestion (Kern, 1998), because of its ...

  • Integrated environmental biotechnology-oriented framework for solid waste management and control in Nigeria

    Several environmental problems arising from man's activity have to be solved in a cost-effective and an environmentally friendly approach. In this paper, a framework for an integrated management and control of solid waste in the south-east zone of Nigeria is presented. The major activities include collection and transportation of solid waste to designated areas, separation of reusable components ...

  • Status and trends for biomass use and consequences for waste management - the example of Germany

    While separate collection and treatment of organic waste in Germany had a magnitude of 100.000 Mg in 1985 it currently extends to 8.2 Mio. Mg of which about 50% each refers to biowaste and green waste respectively. However, a further potential of 8 million Mg of organic waste collected with other residual waste still exists. Rapidly increasing costs for the treatment of residual waste coupled ...

  • Rest or mixed waste sorting-digestion-separation for the recovery of recyclables and energy

    Source separate collection of biowaste has been implemented in many countries in Europe, especially in the German- speaking countries and the Benelux. By separating the biowaste fraction, a waste fraction called rest waste or grey waste is left over. This fraction is in most instances landfilled or incinerated. However, rest waste still contains a considerable amount of organics (up to 65%) which ...

  • Composting in flanders: the vlaco experience

    In Belgium, waste policy mainly belongs to the responsibility of the regional authorities. Therefore, apart from some European regulations, Flanders, Wallonia and Brussels have their own laws, rules and strategies with respect to waste management. These different situations are inevitably related to the political, socio-economic and natural conditions of these regions. In execution of the Waste ...

  • Environmental evaluation of systems for the recovery of biogenic wastes

    The recovery of waste materials is promoted by the German Waste Act 'Kreislaufwirtschafts- und Abfallgesetz'. It requires that among the recovery routes available for a specific waste category the priority has to be on those which are more environmentally compatible. As a restriction given by the law, only those recovery routes which are technically feasible and economically reasonable must be ...

  • A hot chance: exhaustive anaerobic digestion of “grey waste” under temperatures of pasteurization

    According to German laws municipal residual refuse MRR (biowaste, paper and glass are collected in separate bins) must be nearly mineralized before it will be deposited in a landfill, since this material can still contain 20 - 50 % biogenous organic matter leading to gaseous and liquid emissions. Especially the high-organic sieve fraction of MRR below 40 - 60 mm and with a thermal energy content ...

  • 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 ...

  • Dreyer & Bosse deliver renewable energy CHP project to Sofia in Bulgaria

    The Sofia council decided to invest in renewable energy to make use of the many tons of biowaste (vegetative material),  20,000 tons per annum, from the waste removal collections that take place daily in Sofia and surrounding area. To make this possible it was decided to go for wet fermentation where the substrate or raw material ferments and the biogas is collected. After three weeks the ...
