  • Contained Composting Systems Rewiew

    Having gained success in recycling yard trimmings, composters and recycling coordinators are reaching deeper into the organic residuals pile to capture other feedstocks. In particular, their sights are set on source separated food materials, from institutions (e.g. schools, hospitals), grocery stores and produce markets, food processors and commercial food service facilities (e.g. restaurants). A ...

  • 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: ...

  • Mariposa compost facility odor remediation update

    Staring in the winter of 2006 the staff at the Mariposa Compost Facility worked quickly to make process changes to bring odor issues under control. Here is the latest chapter in their story. Odor (incident) Logs In January 2007 the Local Environmental Agency (LEA) provided "odor logs" to the county residents that were troubled by the compost facility's odors. The odor logs were ...

  • 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 ...

  • 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 ...

  • South Kern Compost manufacturing facility case study

    The Challenge Seated approximately 30 miles southwest of Bakersfield, California, the South Kern Compost Manufacturing Facility (SKCMF) was commissioned in 2006 to alleviate concerns about long-term viability of land application of Class B biosolids in Southern California, and address air quality issues of previous traditional composting processes. The Solution ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Troubleshooting the Compost Pile

    While composting is a biological process, we as composters must provide the microorganisms that do the work with the conditions they need to do their job. If there is a problem with the system, then look at it from the point of view of the microbe. What does that microbe need to function, and why isn’t it functioning correctly? Microorganisms need a source of energy organic feedstocks to feed on ...

  • 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. ...

  • Fires at Composting Facilities: Causes and Conditions

    The subject of fires at composting facilities is a bad news/good news situation. The bad news is that fires are more common than we realize. Ask a group of facility operators if they have had to deal with a fire, and the majority will quietly admit they have. The good news is that we don’t realize that fires are fairly common at composting facilities. Most are neither frequent nor destructive ...
