organic waste mechanical treatment Articles

  • Mechanical biological treatment trends

    Composting mixed municipal solid waste has a long tradition in Germany. In 1953, the first large-scale facilities in Baden-Baden and Blaubeuren started operating, followed later by plants in Heidelberg, Duisburg and other locations across the western part of Germany. Facilities were being opened to provide alternatives to landfilling MSW, and to produce compost for agricultural use. The quality ...

  • Anaerobic digestion as integrated part of a mechanical-biological Waste treatment process

    Anaerobic digestion as a means of stabilising residual municipal solid waste (RMSW) before landfilling was evaluated to study the stabilization of RMSW through mechanical-biological processes and evaluate the effect on landfills. The tests were at the site of WGV Recycling GmbH in Quarzbichl between September 1995 and March 1996. The trials, which were run with a single-phase anaerobic digester, ...

  • Mechanical Biological Treatment (MBT): The new kid on the UK waste management block

    Waste management in the United Kingdom (UK) has undergone a revolution in the past 20 years. In 1990, the UK landfilled more than 90 percent of its municipal solid waste (MSW), incinerated about 8 percent and recycled the remaining 2 percent. It had one the highest landfill rates in Western Europe and one of the lowest recycling rates, reflecting the UK’s mining traditions and aggregates ...

  • Alternative stabilisation options of mechanically sorted organic fraction from municipal solid waste prior to landfill disposal

    In order to foresee the measures of the Directive 1999/31/EC, waste management policies are focused on the reduction of organic matter landfill disposal, through the recovering of the organic waste stream or the pre-treatment of residual wastes before landfilling. This paper discusses the advantages and disadvantages of possible stabilisation treatments of the mechanically sorted organic fraction ...

  • Influence of the comminution of organic waste on their biodegradability

    Organic solids are present in very large quantities as products or waste from agriculture, food industry, household and many other fields. The disposal of organic waste can be realised using biological processes like anaerobic digestion or aerobic composting. The anaerobic digestion has advantages in comparison to composting such as a better handling of wet waste, the production of useful ...

  • Life cycle assessment of the mechanical biological pretreatment of residual wastes

    In Germany the handling of wastes is regulated by the 'Kreislaufwirtschaftsgesetz (i.e. Closed Cycle Economy and Waste Act) which gives priority to waste avoidance. Waste that cannot be avoided has to be recycled or reused as long as it is environmentally favourable. The residual wastes have to be pre-treated before landfill to reduce the negative effects of the landfill as production of landfill ...

  • The fate and behaviour of organic micropollutants during wastewater treatment processes: a review

    The fate and behaviour of selected insecticides, herbicides, and polychlorinated biphenyls during primary sedimentation and secondary biological treatment of waste water are evaluated. The physico-chemical properties (chemical structure, aqueous solubility, octanol/water partition coefficient and Henry's Law constant) of these compounds which dictate the extent and mechanism of their removal ...

  • 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 ...

  • Halogenated Volatile Organic Compounds

    Sites where halogenated VOCs may be found include burn pits, chemical manufacturing plants or disposal areas, contaminated marine sediments, disposal wells and leach fields, electroplating/metal finishing shops, firefighting training areas, hangars/aircraft maintenance areas, landfills and burial pits, leaking collection and system sanitary lines, leaking storage tanks, radioactive/mixed waste ...

  • Case study - Deodorization at waste water treatment plants

    The presence of microorganisms in wastewater causes a decrease in dissolved oxygen levels due consumption by the organisms’ metabolic processes. The more microorganisms there are, the greater the biological demand for oxygen. When this demand exceeds that which can be provided by the exchange of air, an anaerobic process begins, thus creating a reducing environment that favours the ...

  • The state of composting and biological waste treatment in the UK

    In 2005/06 3.4 million tonnes of source segregated waste was composted, an increase of 28% on the previous year. 85% was municipal waste, with just over half of this collected at civic amenity sites Less than one per cent of municipal waste was kitchen waste collected at the kerbside 65% of waste composted was composted at dedicated composting / biological treatment sites, with 10% on farm and ...

  • Behaviour of Bulk and Trace Organics in a Full Scale Membrane Bioreactor for Landfill Leachate Treatment

    ABSTRACTLandfill leachates are generally highly pollutant wastewaters which have percolated through a deposit of solid waste. In many states it is now required to collect and treat landfill leachates to avoid contamination of surface and groundwater bodies. A state of the art technology for landfill leachate treatment uses membrane bioreactor technology prior to potential polishing with dense ...

  • Bioremediation of Nitrochlorobenzene, Nitroaniline, Chloroaniline, and Other Organics in Groundwater.

    ABSTRACT: The uppermost aquifer beneath a chemical plant contains residual concentrations of o-nitrochlorobenzene from a tank car spill, as well as other plant-related organic compounds of concern (COC), including 2-nitroaniline and o-chloroaniline. The aquifer consists of low permeability clays and silts, and produces only a few gallons of groundwater per day from a shallow ...

  • The Right Forces · Producing Power from Recycled Organics

    FOR the more than 200 persons attending the BioCycle “Renewable Energy from Organics Recycling” Conference held October 29-31 in Des Moines, Iowa, there was a sense they were part of “a profound revolution that is developing in our entire energy system.” The sessions revealed how timing, commercial systems, our nation’s priorities and research knowledge have coalesced. Recovery of biomass — ...


  • Composting of municipal waste in Poland

    Composting constitute an important element of the integrated systems of municipal waste management, which is being developed these days. In such systems, the process is employed mainly in the treatment of selectively collected biologically degradable moist waste coming from kitchens, gardening and municipal green places. The biological treatment of mixed municipal waste, however, is employed ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Management of Hazardous Wastes

    ' Management of hazardous waste is a growing concern in many countries. The long-term impacts and costs of improper disposal can be very high and the emphasis must be on prevention. A comprehensive management system should include (i) policies, institutions and effective regulations and (ii) adequate and acceptable disposal facilities (either public or private). This note outlines the key ...
