  • 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 ...

  • Impact of organic residues on soil microorganisms

    It is well known that organic residue amendments to soil give beneficial effects such as provision of plant nutrients, increased humus content and thereby increased water holding capacity, improved structure and increased cation exchange capacity. Organic wastes can be a valuable fertiliser in terms of phosphorous. Chemical precipitation in the sewage treatment plant makes sewage sludge rich in ...

  • Automotive Shredder Residue (ASR) - From Waste to Products

    The paper will explain WESA-SLF, a dry-mechanical process to treat ASR with the aim to achieve usable products, mainly organic materials, metals, and minerals. Detail information will be given about the first plant for processing 4 tons per hour ASR which had its start up end of 1999. The experience with the first months in operation as well as with the quality of the products and the influence ...

  • Diverting Food Residuals in Minnesota

  • 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 ...

  • Decomposition of major organic components during mechanical-biological pretreatment of residual municipal solid waste

    Landfilling of untreated municipal solid waste (MSW) generates environmentally hazardous gas and leachate emissions (El-Fadel et al., 1997). The aim of mechanical-biological waste pretreatment (MBP) is to anticipate this process in a controlled system and to avoid later emissions in the landfill (Leikam and Stegmann, 1997). Main source of these emissions is the microbial metabolism of the easily ...

  • Stabilisation and Acceptance Criteria of Residual Wastes - Technologies and their Achievements in Europe

    ABSTRACT The focus of the EU landfill directive is the reduction of biodegradable waste destined for landfill on a solely quantitative basis. Trials on the bio-mechanical treatment and its effect on the landfill behaviour show that the quality of the remaining organic fraction for landfilling should be considered because it is is more relevant than the quantity of biodegradable waste, in terms of ...

  • Energy Recovery from Residual Waste by Means of Anaerobic Digestion Technologies

    ABSTRACT Anaerobic digestion (AD) is a natural process, spontaneously taking place in natural surroundings, such as marshes,bogs, paddies, or in cesspits, landfills, and dedicated digesters, used for the conversion of organic waste into a rich gas. Typical AD substrates are: manure, sewage sludge, high BOD wastewater, and – more recently - the organic fraction of Municipal Solid Waste (MSW), ...

  • 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 ...

  • Impact of CO2 Emission Trading Schemes on Residual Waste Management

    ABSTRACT The EU-Emission trading scheme (ETS) in its current design hardly affects residual waste management directly: methane from landfill-sites is not included although it is one of the “Green-House-Gases” (GHG) of the Kyoto Protocol, CO2-emissions from waste incineration plants are generally exempted from the regulation of the directive and emissions from combustion of landfill-site gas can ...

  • Zeroing in on Organics

    The months of January and February are data gathering time for BioCycle’s annual State of Garbage In America survey. For many state solid waste, recycling and composting officials, the year doesn’t get off to the right start if they don’t see one of our questionnaires coming across their fax or email lines! The data gathered from these state offices has enabled BioCycle to track the nation’s ...

  • Treatment of organic wastes in malaysia . Problems and Prospects

    Solid waste is one of the biggest environmental problems in Malaysia (Hassan et al. 1995). The amount generated continues to increase in response to rapid increase in population and accelerated urbanisation and industrialization processes. Immediate and long-term strategies are required to ensure that the country’s rapid economic growth is not achieved at the expense of massive pollution ...

  • 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 ...

  • Time to address the air pollution control residue problem

    The incineration of municipal solid waste is gaining increasing importance in the UK, especially as the burning of waste can be used to generate energy, providing a more sustainable solution to our waste problem by diverting it from landfill sites. An issue with incineration is that some of our waste contains hazardous chemicals such as chlorine and lead which are volatilised during the process. ...

  • Composition and Contaminant Loads of Residual Household Waste Part III: Physico-Chemical Properties and Contaminant Concentrations

    Abstract. Physico-chemical properties of residual waste are key factors for disposal standards. Reliable input data for treatment plants (MSWI) need to consider the heterogeneity and variability of waste composition. This requires thoroughly designed sampling schemes, a consistent separation of bulk waste into uniform fractions, and adequate methods for sample preparation and analysis. The ...

  • Residual effect of agro–industrial wastes on soil properties and Zea mays (L.) nutrition

    The residual effect of agro–industrial wastes previously used for potato growing was investigated for soil characteristics and maize nutrition. The soil pH increased and organic matter decreased during maize growth. Nitrogen and K were generally low, but statistically higher almost in waste–applied soils. Soil phosphorus was greatest in the 'Only Wastes' and 'Min.P + Wastes NK' treatments. N, P, ...

  • Management of organic wastes by earthworms: dual benefit for environment and society

    In the present study, two earthworm species, Eisenia fetida and Eudrilus eugeniae were employed to degrade the vegetable wastes and agro-residues. Chemical analysis of the vermicomposts derived from vegetable wastes showed that the quantity of organic carbon was reduced from 42.1% to 31.19 and 30.19% by E. fetida and E. eugeniae, respectively. The level of nitrogen, phosphorus, potassium and ...

  • 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 ...
