  • Of biodegradable, compostable, paper plates and marketing

    What if I told you there was no such thing as a biodegradable product? Would it bring to mind images of products you have seen at the local store that are promoted as biodegradable? Would you think I was swimming out of the mainstream? Well according to the FTC, in many cases, it just may be true if you are being marketed a biodegradable product and the seller doesn’t qualify that claim. On June ...

  • 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 ...

  • 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 ...


  • Compost curing reduces suppression of plant diseases

    Prolonged curing of compost reduces risks of phytotoxicity but may also have an undesirable effect on suppressiveness against soil-borne diseases. In a previous study, this effect was demonstrated for a compost produced from a mixture of yard waste and biosolids, against Sclerotium rolfsii. The aim of the present study was to demonstrate that similar effects of prolonged curing may be exhibited ...

  • Potential pollutants from farm, food and yard waste composts at differing ages: Part I. physical and chemical properties

    There is little information about the changes in physical and chemical properties of compost as a function of compost feedstocks and age of the compost mixture. As a consequence of this gap, the potential of compost to serve as a pollutant source relative to compost age (from initial mixing of raw feedstocks to mature compost) and feedstocks (i.e. % of food, manure, bedding, leaves, etc.) during ...

  • Effect of covering composting piles with mature compost on ammonia emission and microbial community structure of composting process

    Received for publication February 14, 2008. To control ammonia (NH3) volatilization from the dairy cattle (Bos taurus) manure composting process, a compost pile was covered with mature compost and the gas emissions evaluated using the dynamic chamber system. The peak of NH3 volatilization observed immediately after piling up of the compost was reduced from 196 to 62 mg/m3 by covering the compost ...

  • Pilot project cuts odor, cost for humanure compost

    Utah Valley Daily Herald Article on the benifits on using micro-pore membrane compost covers when composting highly odorus material.  In February of 2009 Utah Valley's North Sewer Distirict conducted a pilot study to determine the effectivness of mirco-pore membrane compost covers in reducing odors from biosolids (sewage sludge) composting.  Odor testing was conducted over a term of one ...

  • Compost/landclearing firm keeps pace with St. Louis area growth

    While many metropolitan areas in the country's midsection are experiencing something of a population exodus, with people either seeking new economic opportunities or just the benefit of warmer climes, St. Louis and its surrounding areas have instead seen a resurgence of growth. Today, St. Louis County boasts a population that is one-fifth of the state's overall total, a health care industry that ...


  • Design and performance of a simulated feedstock for composting experiments

    This paper reviews the composition and performance of simulated feedstock mixtures previously employed in composting research, and presents a new simulated feedstock.

  • Extractability, plant yield and toxicity thresholds for boron in compost

    Boron (B) is a trace element essential to crop growth in small soil concentrations (0.2-1.5ppm), yet may produce plant toxicity symptoms readily as the amount in the soil solution increases over 2ppm. Boron is present in significant amounts in recycled materials such as municipal solid waste (MSW) and coal fly ash, and therefore composts containing these ingredients may potentially exceed ...
