  • 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 ...

  • The biowaste-programme of the german environ-mental foundation - Results, conclusion and perspectives

    The biowaste programme of the German Environmental Foundation was started in 1995. Since its beginning 55 projects were supported with more than 32 Mio DM (ca. 16 Mio EURO) focussing the following sectors: i) development and application of new compost-based products; ii) reduction of pollutants and higher effective pre-sorting of extraneous materials; iii) innovative technologies of biowaste ...

  • 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 ...

  • European Experiences With the Treatment and Digestion of Bio-Organic Waste

    In the area of waste management environmental awareness has essentially increased and according technologies got more and more accepted in Europe within more than ten years now. During all the time BTA has gathered experiences by developing and realising flexible concepts for biowaste treatment plants of different design and capacities for the treatment of various waste streams: full scale plants ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Composting in flanders: the vlaco experience

    Currently, the Flanders waste policy is based on the so-called ‘ladder of Lansink’. Six aerobic composting and one anaerobic digestion plant are operational for the treatment of biowaste. Some new composting plants are foreseen for 1999 and/or 2000. Composting retention time varies from 10 to 15 weeks. Green waste is treated in 15 open air composting plants. With respect to the use of compost ...

  • Reasonable waste digestion plants

    During the last years it became quite clear that in the area of utilisation of organic waste the anaerobic digestion has developed a leading position. This is not only based on its well known advantages:- abhigh rate degradation of organics- abcontained process- ablow emissions- abhigh yield of CO2-neutral produced biogas and high quality compost as its productsbut also on the fact that customers ...

  • Digester gas - Stornoway Scotland - case study

    Scottish Island to be the first to utilise Anaerobic Digestion in waste treatment Comhairle nan Eilean Siar Stornoway, Isle of Lewis, Scotland “We were convinced by ENER-G’s ability to install a system that met with our requirements for a facility that is an innovative combination of waste treatments and includes the UK’s first dry Anaerobic Digestion facility” ...

  • 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 ...
