  • ECS compost aeration floors - the foundation of aerated compost system design

    Inventive minds have come up with an amazing number of variations to channel air through a floor and into, or out of, a compost pile. Designs that have been based on sound engineering calculations and experience have generally worked. However, since all aeration floors are constrained by physics and Murphy, the floors that were less rigorously designed have not faired well. The characteristics by ...

  • 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 ...

  • How many days does it take to ferment organic fertilizer

    Most domestic organic fertilizer products can only be composted and fermented for 7-10 days, and such products can only reach the harmless standard. The fermentation process of high quality organic compost usually takes 45-60 days. This is because in the early stage of heating and high temperature of the organic ...

  • A new Technology for Composting: Suction Aeration for Opening Composting Works

    Cost-efficient solution for smell emission reduction The enormous waste quantities that are produced day by day are one of the most difficult problems for the economy as such, for cities and communities and for private households. Storage capacities for waste are scarce everywhere. Therefore solutions of all kinds that reduce waste quantities or recycle waste materials to be reused in the ...

  • Leaf composting in cold climates: a theoretical and an experimental evaluation

    There are many factors influencing the process of composting organic waste. This paper provides an experimental and theoretical evaluation of the leaf composting process to elucidate the importance of these various factors during composting of leaves. The analysis is performed specifically for the environmental conditions encountered in cold climates. Theoretical models are developed to evaluate ...

  • Influence of environmental parameters on the composting kinetic of lignocellulosic residues

    The kinetic of the thermophilic composting process of trimming residues was studied under several parameters [moisture (40-70%), aeration (0.2-0.6 l air/kg min) and particle size (1-5 cm)] in order to determine the best composting conditions to ensure an optimum composting design. Under those conditions, suitable temperature evolutions have been found for all the reactors. The kinetic model ...

  • The influence of aeration system, temperature and compost origin on the phytotoxicity of compost tea

    Numerous studies have evaluated compost teas’ capacity to suppress plant disease, but no study has been made of possible compost tea phytotoxicity. In this study, 24 assays were carried out on compost tea produced from three different composts: one produced from bovine manure (M) and two others made from municipal solid waste but differing in the degree of stability (stable: MSW I and unstable: ...

  • Compost Dried Primary Sludge – A Renewable Energy Source?

    Abstract Napier is a city of almost 60,000 population on the east coast of the North Island, New Zealand. Napier City Council planned to upgrade its Awatoto Wastewater Milliscreening (0.75mm aperture) plant to advanced primary treatment (APT) and ultraviolet disinfection to improve the quality of discharge to the ocean through the existing 1600m long outfall into Hawke Bay. The APT plant ...

  • Cocomposting at Pearl Harbor

    Cocomposting at Pearl Harbor When the Hawaii Department of Health tightened its restrictions on landfilling biosolids by requiring the lining of sludge drying beds, the U.S. Navy Public Works Center (PWC) at Pearl Harbor decided to look for a less expensive alternative to landfilling. Biosolids composting became the Navy’s answer. A pilot project was started in July, 1997, and the full-scale ...

  • Calculating capacity at composting sites

    The addition of new composting facilities or expansion of capacity at existing ones is becoming more and more difficult as feasible sites are taken out of circulation. This has created interest in maximizing the unit production of compost at composting sites so that they perform as efficiently as possible. The need is especially acute if physical expansion is not possible, but increases in ...
