  • Composting dairy solids with the ac composter

    In October, ECS began conducting trials at California State University Fresno to explore using the new patent pending AC Composter system to manage dairy manure solids and comply with air-quality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF's research dairy. This research is being conducted with funds from a USDA Small Business Innovative Research ...

  • A cost-effective method for controlling compost air emissions

    In October 2007, ECS began conducting trials at California State University Fresno (CSUF) to explore using the new patent pending AC Composter (ACC) covered aerated static pile system to manage dairy manure solids and comply with airquality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF research dairy. This research is being conducted under a Phase I ...

  • Air space in composting research: A literature review

    Free air space (FAS), as a representation of the available air filled voids in a composting matrix, is considered an important parameter to define optimum substrate conditions for gas transfer. However, this parameter has been determined, interpreted, and employed in several ways by researchers. On this basis, the objective of this paper is to review the previous work related to the application ...

  • A study on Air Filled Porosity evolution in sludge composting

    Air Filled Porosity (AFP) is a key parameter in the composting process, conditioning oxygen availability and heat accumulation. Air pycnometry is considered the most adequate methodology for AFP determination. This technique requires withdrawing a sample of material from the composting mass for AFP measurement, which may alter its physical characteristics. A novel strategy that permits to measure ...

  • 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 ...

  • 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 ...

  • Municipal composting - Case Study

    Application TEG Environmental are world leaders in rapid composting, and as part of a major programme to cut the amount of municipal waste going to landfill, they are installing new state of the art “in-vessel” composting facilities in Rochdale and Bredbury. These will be capable of handling 180,000 tonnes of green and food waste each year, and are scheduled to come on stream ...

  • Composting in flanders: the vlaco experience

    Currently, the Flanders waste policy is based on the so-called ‘ladder of Lansink’. Six aerobic composting and one anaerobic digestion plant are operational for the treatment of biowaste. Some new composting plants are foreseen for 1999 and/or 2000. Composting retention time varies from 10 to 15 weeks. Green waste is treated in 15 open air composting plants. With respect to the use of compost ...

  • 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 ...

  • 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 ...

  • In-Vessel Composting of Residential Organics

    In 1994, the Regional Municipality of Peel began work on a system for residential organic residuals collection and composting. Although Peel had been promoting backyard composting, greater diversion rates were sought. The public was surveyed to determine what level of cooperation could be expected for source separation and setting out of food, soiled paper products, yard trimmings, etc. “We knew ...

  • Odourless composting in Brussels

    Located in the small city of Vorst, which is part of the greater Brussels area, Brussels Compost was faced with the problem of being surrounded by residential areas. The outside composting process produced quite an odour, and as a result of the complaints from the surrounding neighbourhood, renewal of their operating permit was uncertain. Relocation was not an option so Brussels Compost decided ...


  • 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 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 ...

  • Devontalk - Composting in schools in Devon

    Do you know what London's 02 Arena and Okehampton College have in common? It's something called Big Hanna, a huge shiny composter that turns all their food waste into compost. Big Hanna arrived in Okehampton last year and immediately made her presence felt because someone had to look after her and feed her regularly. That someone is Okehampton-born and bred Gary Drew, who went to the college ...
