  • Evaluation of FTIR spectroscopy as a maturity index for herbicide-contaminated composts

    This paper analyses the use of Fourier Transform Infrared (FTIR) spectroscopy as a maturity index for herbicide-contaminated green wastes composts. Four in-vessel composting systems were set-up with Compost A constituting of uncontaminated grass clippings and Composts B, C and D contaminated with atrazine, 2,4-D and tordon 101 respectively. The physicochemical properties of the composts were ...

  • Odor issues at Mariposa MSW composting facility

    The Mariposa County MSW composting facility was built at the county landfill to remove some dry recyclables from the waste stream and to produce compost for daily cover. One key motivation was to increase the lifespan of the landfill and to postpone a costly long-haul. The facility was permitted, designed and built by a team of engineers and vendors. It began operation in the summer of 2006. ECS ...

  • Case Study - Composting food waste generated by 8,000 room resort in Cancun

    Food waste composted with the in vessel composter by XACT is solving the organic waste problem of an 8,000 room hotel in Cancun, Mexico.  The Cancun Palace Resort generates 2500 tons of organic waste per year, and wanted/needed to reduce their high waste haulage costs and landfill tipping fees.  In addition, the hotel management wanted to take meaningful action to reduce their GHG ...

  • Mariposa compost facility odor remediation update

    Staring in the winter of 2006 the staff at the Mariposa Compost Facility worked quickly to make process changes to bring odor issues under control. Here is the latest chapter in their story. Odor (incident) Logs In January 2007 the Local Environmental Agency (LEA) provided "odor logs" to the county residents that were troubled by the compost facility's odors. The odor logs were ...

  • 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 ...

  • Potential utilisation of pulp and paper mill biosolids in composting and plant production: a case study at St. Marys Papers Ltd. (Canada)

    The use of St Marys Paper biosolids as a soil additive or growth cover was investigated. Biosolids were mixed with a commercial potting media in five vol/vol ratios and employed in a greenhouse study. The biosolids were found to improve Pinus banksiana seedling growth, a 50% biosolids:50% ProMix mixture yielding the tallest plants and highest dry mass. To further biologically stabilise the ...

  • An assessment of the suitability of backyard produced compost as a potting soil

    Current scientific knowledge of compost is largely derived from research into commercially produced green compost. This has shown that such compost tends to have high pH, high conductivity, and potential for organic and/or mineral pollutants and therefore can be problematic for use in growing media at high inclusion rates. Little work has been undertaken at an amateur composting scale and it is ...

  • Tennessee composting facility makes full recovery

    After a fire in 2007 destroyed the plant, Sevier Solid Waste, Inc. has constructed a new and improved facility that reflects lessons learned from years of composting mixed waste and biosolids. THE small subset of the composting industry that uses rotary drum reactors (RDR) gets together for two days each year at an operating facility to share experiences with rotary drum in-vessel composting. In ...

  • Effects of bulking agents, load size or starter cultures in kitchen-waste composting

    Background :To prevent the interruption of the carbon cycle by the disposal of waste to landfills, organic kitchen waste requires proper treatment such as composting to reduce its uncontrolled degradation on disposal sites and subsequent greenhouse gases, odour emissions and nutrient losses. This study investigated the effects of bulking agent, newspaper and onion peels, composting waste load ...

  • What`s New - In-Vessel Composting

    IF YOU are considering some sort of enclosed vessel for composting food residuals, yard trimmings, biosolids, manure, animal mortalities or other waste streams, there is no shortage of options to consider. Domestic and international technology providers offer agitated and nonagitated enclosed systems, as well as rigid and nonrigid containment. Unlike some of the other equipment categories in ...

  • 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 ...

  • Ohio Takes Aim At Food Waste Composting

    WHILE RECYCLING of paper and yard trimmings have grown rapidly in Ohio in the last 30 years - now up to 50 percent for paper and 62 percent for green materials, the recovery rate for food residuals is at less than three percent of nearly 96 million tons generated annually. To turn things around, the Ohio EPA and its Solid Waste Management Division have teamed up to get the word out about ...

  • 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 ...

  • Mixed MSW composting in transition

    WITHOUT a doubt, composting the mixed municipal solid waste stream is a “niche” business. It is an MSW management option that seems to be viable in very specific situations. In some instances, these plants were built to service tourist destinations, often in somewhat rural areas where recycling is difficult and landfills are distant. In several other cases, public agencies built plants to extend ...

  • 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. ...

  • 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 ...

  • Straight From the Source : Operator Strategies to Maintain Screen Performance

    In early December, BioCycle editors e-mailed selected composting facility operators, asking them a series of questions about their screening operation. The minisurvey focused on strategies to maintain performance of screens used for preprocessing incoming feedstocks and/or for screening finished compost. Six operators responded: Adam Sherman, Intervale Compost Project in Burlington, Vermont; ...

  • 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 ...
