  • Field Testing Protocol For Compostable Packaging

    Compostable product disintegration trials conducted in British Columbia help lay groundwork for open source, field testing protocol. Compostable packaging holds great promise to aid in diverting food waste from landfill. However, even when certified compostable, the products disintegrate differently across facility types. A growing number of composting facilities see potential for ...

  • 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 ...

  • 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 ...

  • 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 Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • WASATCH Composting Facility

    Wasatch Integrated Waste Management District utilizes the Aerated Static Pile (ASP) Composting System designed by Managed Organic Recycling, Inc.  The system was installed to reduce odors that occured during the previously used open windrow composting method.  Phase one is currently under construction with completion estimated by Summer of 2013 and Phase two will commence with the ...

  • 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 ...

  • Composting In rural Alaska

    Gardeners, communities and commercial enterprises have proven that composting works in Alaska, especially given large quantities of fish waste and diminishing landfill capacity. ALASKA is two and a half times larger than the largest state in the lower 48 states. Over half of the entire state’s population lives within the municipality of Anchorage. Many Alaskan villages can only be reached ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak’s crews put materials through a Vermeer tub ...

  • Understanding Compost Tea

     Understanding Compost Tea COMPOST TEA describes many different preparations made using compost as a starting material and producing a liquid extract or in some cases a “liquid version” of the original compost. There are many home-designed pieces of equipment and some commercially available equipment made to produce compost tea. New ideas abound on how to fabricate the better tea-maker and ...

  • Composting Advances in Oregon and Washington

    Over the years, different forces have served as drivers to help grow the composting industry. For example, in the late 1980s and early 1990s, it was the perceived landfill crisis that led to state bans on disposal of yard trimmings. Composting also has benefitted from a push to meet recycling goals, which has prompted states and local governments to go beyond yard trimmings and into such ...

  • Effect of different forced aeration methods on Vertical temperature distribution and reaction rates During composting

    The application of forced aeration, namely in the upflow (blowing) or downflow (suction) mode has been increasing in modern composting processes. These aeration modes often create a sharp temperature gradient in the composting mass. Examples of widely varying temperatures at different layers of controlled and non-controlled aerated piles have been reported frequently (Fernandes et al., 1994; ...

  • 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 ...

  • Building Longevity into Composting Buildings

    There are a variety of corrosion resistant options for enclosed composting facilities, where the harsh environment shows no mercy to exposed metal surfaces. MOISTURE is no stranger in Canada's Maritime provinces, so when the Fundy Region Solid Waste Commission (FRSWC) in Saint John, New Bruns-wick embarked on a composting program, putting the operation indoors was a practical choice. The ...

  • 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 ...

  • Food Residuals Composting in the U.S.

    For many years, the public sector has been at the forefront of the developing composting industry. For example, when biosolids composting first got started, it was the sanitation departments of municipalities and local sanitary authorities pushing projects. With yard trimmings composting, municipalities and counties were the primary entities developing programs. Even the fledgling steps of solid ...
