organic waste composting 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 ...

  • Rotary drum composting of different organic waste mixtures

    The effects of three different mixtures of organic waste on composting in a rotary drum were examined by measuring changes in physico-chemical and biological parameters. It was observed that the time courses of the three mixtures: run A (grass cuttings, vegetable waste and food waste), run B (cattle manure, vegetable waste and sawdust) and run C (cattle manure, food waste, vegetable waste, paper ...

  • Mixed organic waste composting using rotary drum composter

    A combination of vegetable waste, cattle manure and saw dust was utilised for high rate composting in a household rotary drum composter. It was found that temperature remained above 55?C for a period of two days, Faecal Coliforms and Faecal Streptococci decrease from 7.5 ? 108 to 5 ? 102 and 1.5 ? 107 to 5 ? 103 bacteria/g, respectively. Negligible VFAs production indicated full aerobic ...

  • Home composting of organic waste - part 1: effect of home composter design

    Worldwide, health and environmental considerations encourage landfill diversion of the organic fraction (OW) of municipal solid wastes, through alternative such as home composting. Of poor sanitation, and trace element and toxic hydrocarbon content (PAH) documentation, this study compared against a laboratory composter (LR), the performance (temperature regime and compost quality) of four 300 to ...

  • Composting Process and Organic Fertilizers Production

    Illustrated explanation of two broad stages that are usually applied in most composting facility. First, composting process that convert raw compost into mature compost. Second, organic fertilizers production that convert mature compost into granulated fertilizers. Feedstock for composting stage can be farm and animal husbandry wastes, biomass from plants, and biodegradables that have been sorted ...

  • 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 ...

  • 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 ...

  • Composting of selected organic wastes from peri-urban areas of Harare, Zimbabwe

    the composting process of peri-urban household wastes, changes that occur during composting, and the properties of the composting products that are of importance for use as soil amendments were studied. Seven different composting mixtures were made in large piles consisting of fallen tree leaves and fresh vegetable leaves mixed with grass or maize straw (0%, 10%, 30% and 50% w/w), wastes common ...

  • Application of household compost bin for diversion of organic wastes in small communities of Thailand

    Natural ventilated and aerated composting units were developed for household, fresh market and restaurant wastes. Household wastes required 8-10 weeks of composting period. The final compost product contained N : P : K content higher than organic compost standard. In aerated unit, the composting period was 30-40 days. Economical analysis suggested Benefit-Cost (B/C) ratio and Economical Internal ...

  • Home composting of organic waste - part 2: effect of management practices

    Home composting (HC) can produce safe compost if properly managed, while reducing municipal disposal costs. This project investigated the sanitary and safety impact of HC management (with/without bulking agent, batch/weekly feeding, with/without regular mixing) using the Plastic (P) and Wood (W) bins, the Rotary Drum (RD) and the Ground Pile (GP) filled with equal wet volumes of food waste (FW) ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Effects of C/N ratio on mixed organic waste composting in a rotary drum composter

    Effects of Carbon to Nitrogen (C/N) ratio on the rotary drum composting of organic waste were examined by measuring changes in various parameters. It was observed that time courses of four C/N ratios: 16, 22, 30 and 38 were different. Initial C/N ratio 22 produced high-quality compost (total nitrogen-2.1%, total phosphorus-4.3 g/kg) within 20 days. While in case of C/N 16, compost yields 1.8% ...
