organic waste compost technology Articles

  • Composting

    Introduction Composting is a controlled biological process by which organic contaminants (e.g., PAHs) are converted by microorganisms (under aerobic and anaerobic conditions) to innocuous, stabilized byproducts. Typically, thermophilic conditions (54 to 65 °C) must be maintained to properly compost soil contaminated with hazardous organic contaminants. The increased temperatures result from heat ...

  • In-Vessel Composting of Residential Organics

    In 1994, the Regional Municipality of Peel began work on a system for residential organic residuals collection and composting. Although Peel had been promoting backyard composting, greater diversion rates were sought. The public was surveyed to determine what level of cooperation could be expected for source separation and setting out of food, soiled paper products, yard trimmings, etc. “We knew ...

  • Bio-conversion of organic waste using composting technologies – a review

    Composting is nowadays evolving as a highly technical process for processing organic waste separately replacing landfilling along with municipal solid waste. Vegetable waste with high organic content can be composted to produce nutrient rich material that can work as soil conditioner instead of dumping in open landfills. Various studies reveal that due to high organic content of vegetable waste ...

  • Mixed waste composting trends

    It's been about 25 years since vendors started marketing systems to process mixed municipal solid waste via composting in the U.S. Today, there are 13 plants, most fulfilling their niche in the communities they serve - whether managing MSW in high tourism areas, or processing residual organics from materials recovery facilities. Table 1 provides summary data on the 13 facilities. While we did not ...

  • 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 ...

  • 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 ...

  • Composting Key to Meeting Landfill Organics Ban

    The Halifax Regional Municipality (HRM) in Nova Scotia took a giant leap in 1998 to reaching a 50 percent diversion goal by 2000. Between July and November, 1998, organics collection carts were distributed to almost 100,000 households in the region. In December, two new composting facilities designed to process those materials, as well as feedstocks from the commercial sector, opened their doors. ...

  • Waste composting as a component of ecological waste management in the Philippines

    Ecological waste management (EWM) is a system of analyzing solid waste concerns and coming up with solutions that would not pose any harm to the environment. This would imply the use of technologies that are environmentally sound such as waste segregation, waste reduction at source, composting and recycling. Furthermore, this system ought to comply with the vision of sustainable ...

  • Treating organic waste with Cambi® THP

    This paper describes how the Cambi Thermal Hydrolysis Process (THP) treats biodegradable organic waste and converts it to renewable energy and pathogen-free and bio-fertilizer. The interest for the process is expected to increase due to new environmental legislation as well as increasing demand for renewable energy. The implementation of the European Landfill Directive 1999/31EC and the Animal-by ...

  • Fluorescence characteristic changes of dissolved organic matter during municipal solid waste composting

    Dissolved organic matter (DOM) of municipal solid waste (MSW) consists of minerals, water, ash and humic substances, and is known to enhance plant growth. In this study, inoculating microbes (ZJ, MS) were used in municipal solid wastes composting, and composting implemented a industrialized technology. During composting, dissolved organic matter was extracted from the compost and purified. The ...

  • New technology for municipal scale compost operations

    There is a new facility located in Ontario, Canada that accepts construction and demolition waste (C&D) and 100,000 TPY of source separated organics (SSO) waste. The owners chose a new non-thermal plasma (NTP) system to control the odor in its 120,000 cubic feet of air per minute (CFM) air emissions. This NTP system is very compact, fits easily on a platform, is configured as a number of ...

  • Project proposal & documentation for solid waste management (SWM) & production of the organic compost from municipal and household waste in Mannar district – Sri Lanka

    1.1. Brief Description of Problem Statement The organic solid waste has to be produced from Mannar Town in about 12 M.T per day. The higher amount of inorganic fertilizer using in Mannar District and the demand of fertilizer also is high. Our production of organic fertilizer can replace the inorganic fertilizer and we believe the positive environmental impact is expected and may increase the ...


  • Use of vermicomposting biotechnology for recycling organic wastes in agriculture

    Recent trend of declining sustainability in agricultural production is appearing as a major threat to most of the Asian countries. To combat the situation, increasing importance is now being paid on incorporation of organic materials for rejuvenating the health condition and, hence, the productivity of these soils. Large scale availability of conventional organic manures being a big problem ...
