  • 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 ...

  • Compost based products: history, recent activities, chances

    The amount of compost originating from source separated organic household waste collection in Germany is still increasing. At the end of the year 1997, app. 3.0 to 3.5 millions Mg fresh matter of non-mature and mature compost were produced in 515 composting plants with an input of respectively more than 1.000 Mg organic waste per year in Germany. According to Mellen (1998) an estimated 27% of 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 ...

  • 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 ...

  • 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 ...

  • Food composting infrastructure

    From 1995 to 2000, BioCycle published an annual national survey of food waste composting projects in the United States. Since then, we have continued to track food waste composting activity, and in 2007 launched www.findacomposter.com, a publicly searchable data base that lists many sites in the U.S. that receive municipal, commercial, institutional and industrial food waste ...

  • 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 ...

  • 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 ...

  • State Of Composting In The U.S.

    The benefits of composting are well documented. Compost is a valuable soil conditioner. It adds needed organic matter, sequesters carbon, improves plant growth, conserves water, reduces reliance on chemical pesticides and fertilizers, and helps prevent nutrient runoff and erosion. Composting also reduces the volume of materials that might otherwise be disposed in landfills or trash incinerators, ...

  • 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 ...
