  • Building Sustainable Sanitation Systems

    A low cost system of resource management such as composting toilets is helping to mitigate many of Haiti’s social and ecological challenges. The Caribbean Republic of Haiti — the poorest, most environmentally degraded country in the Western Hemisphere with a population of about 10 million — is a case study in forestry and soil fertility mismanagement. A colonial ...

  • Quantification of water extractable contaminants from food waste and biosolids blends at different stages of composting

    Rainfall runoff and leachate from windrows composting organic wastes carry nutrients and pathogens. Water extractability of contaminants in compost impacts the design of runoff treatment systems. This paper reports maximum water extractable nutrients, pathogens, and regulated metals from biosolids and food waste composts as measured from a snapshot sampling of windrows at different stages of ...

  • Minimizing Festival Trash

    The Whole Earth Festival at the University of California-Davis is a student-organized event that takes place annually in early May. The weekend attendance is approximately 30,000 people, with 16 food vendors and 100-plus craft booths. One major emphasis of the festival is environmental sustainability. To minimize waste generation, an integrated solid waste prevention strategy was conceptualized ...

  • Composting releases less air pollution than previously thought - study

    A new study funded by the California Integrated Waste Board (CIWMB) indicates that well-managed composting of green waste and food waste releases significantly less air pollution than previously thought. The study also demonstrates that a relatively inexpensive management technique - covering active compost piles with a layer of finished compost - may lower air emissions even further, by as ...

  • Compost Operators Forum · Modeling a Compost Facility

    GEORGIA leads the nation in poultry production, processing nearly 1.5 billion birds a year. A majority of the poultry operations are concentrated in north Georgia. With over 1.5 million tons of poultry litter produced on an annual basis, some of the resulting issues facing the poultry production industry include: Reduced land area on farms to apply increasing amounts of litter; Increasing buffer ...


  • Mechanical biological treatment trends

    Composting mixed municipal solid waste has a long tradition in Germany. In 1953, the first large-scale facilities in Baden-Baden and Blaubeuren started operating, followed later by plants in Heidelberg, Duisburg and other locations across the western part of Germany. Facilities were being opened to provide alternatives to landfilling MSW, and to produce compost for agricultural use. The quality ...

  • Small-Scale Biosolids Composting

    Cambridge, Ohio retrofitted a portion of its vacuum assisted drying beds into a covered composting facility, processing about 300 dry tons/year of biosolids and wood chips. Like many small communities in an agricultural area, the City of Cambridge, Ohio (pop. 14,000) managed biosolids generated by its 2.25 mgd Water Pollution Control Center (WPCC) via land application on farm fields. “Then ...

  • Solution Driven Organics Recycler

    Ag Choice hauls, depackages and produces animal feed and compost. Founders Jay and Jill Fischer embrace new opportunities, and then figure out how to maximize efficiencies and profitability. BioCycle first visited Ag Choice in 2007, two years after Jay and Jill Fischer started their organics collection and composting enterprise in Andover, New Jersey. At the time, composting was an ...

  • Operator Strategies : Sorting Out the Plastic

    BETTER BUGS Ideas and products in the Better Bugs category attempt to affect the biological components and biochemistry of processes by altering the mix of microorganisms or enzymes present. After all, biology is the foundation of many, if not most, organics recycling systems. Pyrophiles: The first example of Better Bugs involves pyrophilic organisms, bugs that can take the heat. This example is ...

  • Composting on Maui hits its stride

    THE Hawaiian island of Maui - a vacation destination for more than 2.2 million people each year - has a year-round growing season that yields a massive stream of green waste from nonstop cutting, trimming and pruning. For years, the resultant trimmings were simply landfilled along with the 500 tons/day of trash. One company, however, decided to turn that tide and has been aggressively taking in ...


  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

  • 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. ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

  • A Citizen`s Guide to Bioremediation

    What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...

  • Source Separated MSW Composting in the US

    MUNICIPAL solid waste composting projects are being launched based on residential separation of the compostable stream from recyclables and trash - quite widespread in Europe and increasingly in Canada. One trend - typically in cities and suburban communities - is to add source separated residential organics to existing yard trimmings collection programs. Composting facilities permitted to ...

  • MSW Composting in the United States

    Massachusetts became home to two new composting facilities that process MSW and biosolids. Nationally, the total number of operating plants is 19. Since the mid-1980s, BioCycle has been conducting an annual, nationwide survey of municipal solid waste (MSW) composting facilities. From the late 1980s into the early 1990s, when it was projected that landfill capacity would drop and tipping fees ...

  • Mixed MSW composting is steady as she goes

    Two new facilities came on line in 2006, while one ceased operation and a second is shifting to a new technology. Annual survey identifies a total of 14 plants. Part I STEADY-STATE may be the best phrase to describe the status of facilities composting mixed municipal solid waste in the United States. In fact, steady-state may be the best phrase to describe solid waste composting in general since ...

  • Wood, Yard Trimmings Recycler Grows by Heaps and Bounds

    GRIND-ALL has been in existence - in one form or another - since 1992. Originally owned by Paul Robins, and operated under the name East Coast Wood Recycling, the company, based in Mosely, Virginia near Richmond, was solely focused on selling wood products at the wholesale level. Three years later Robins joined forces with Robbie Urbine, whose expertise in retail sales allowed the company to open ...
