  • 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 ...

  • 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.

  • Composting Food Residuals on Campus

    Two professors at the University of Wisconsin-River Falls (UW-RF) have used their knowledge of organics recycling projects to implement a food residuals composting program on campus. “It just makes sense in the long run to divert these materials now and lay the groundwork for the future,” says Bob Butler of the Agricultural Engineering Department, who is working closely with Jerry Nolte, an ...

  • 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 ...

  • 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 ...

  • Composting infrastructure trends in the UK

    The European Union's Landfill Directive, which restricts landfilling of biodegradable waste, has made it necessary to develop alternative infrastructures to manage the organic fraction of the solid waste stream. In the United Kingdom, the Landfill Directive has created demand for composting facilities that take source separated organics (SSO), and for anaerobic digestion. Infrastructure also is ...

  • The pulse of the composting industry in Canada

    The Composting Council of Canada (CCC) reflects upon the passion, frustration and determination of its organics recovery advocates, who have made composting visions real. Collectively, these visions are now responsible for diverting about 4 million metric tons of organic residuals or 12 percent of Canada's annual waste stream from landfill - a gigantic leap since the early 1990s when 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 ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...
