  • Windrow co-composting of shredded office paper and Broiler Litter

    The co-composting of shredded waste office paper with Broiler Litter (BL) in windrows was analysed in this study. Two compost mixes were monitored for five weeks; Mix 1 comprised 322kg BL, 117 kg shredded paper and 310L water and Mix 2 consisted of 112 kg BL, 265 kg shredded paper and 290 L water. The initial wet moisture content, initial porosity and initial wet bulk density for Mix 1 were ...

  • The relevance of moisture control in organic municipal Solid waste windrow composting process

    The valorisation of the Municipal Solid Waste composting fraction assumes importance in management strategies of the MSW and constitutes a way of producing an organic material such as humus to improve the soil aeration, the water holding capacity and valuable product when used as soil amendment because it is a source of nutrients (N, P, K) and useful for recovery of poor and degraded soils. It is ...

  • Open-air windrows for winter disposal of frozen cattle mortalities: effects of ambient temperature and mortality layering

    After imposition of fees for disposal of cattle carcasses by the rendering industry, on-farm methods of mortality disposal are being investigated. Three open-air mortality compost windrows were constructed in January (JAN) and February (FEB) of 2004 in the cold, semiarid climate of southern Alberta, Canada. Windrow A included a base of barley straw a minimum of 46 cm thick, a layer of cattle ...

  • Environmental Risk Assessment of compost prepared from salvinia, egeria densa, and alligator weed

    Approximately 70,000 m3 of salvinia (Salvinia molesta) was removed from the Hawkesbury-Nepean River, New South Wales (NSW), Australia, during 2004. This study assessed the risks associated with applying compost prepared from aquatic weeds (AWC) to land, namely, survival and spread of aquatic and terrestrial weeds, eutrophication of waterways, accumulation of heavy metals and phytotoxicity. 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 ...

  • Historical perspective: Screens & air classifiers

    SCREENING equipment for the composting industry has become widely available, with a variety of options — including trommels, star screens, air classifiers and disc screens — to fit specific applications. But early on, in the 1960s and 1970s, screens were often homemade or adapted from other industries. Charles Melhoff, founder of Wildcat Manufacturing Co., says that although they began making ...

  • Rake In Greater Capacity And Higher Hay Quality

    It’s been said that the steel-toothed dump rake was first introduced in the 1860s. Of course, the process back then was to rake hay into piles, which were then pitched onto a wagon for transport to a haystack or the barn loft. To make windrows for the balers that came later, the operator simply spaced the “dumps” equally so they lined up in the field. The irony is that until ...

  • Selected antimicrobial resistance during composting of manure from cattle administered sub-therapeutic antimicrobials

    Received for publication December 10, 2007. Composting is being increasingly employed for the recycling of nutrients in manure from the livestock industry. However, composting manure from animals fed antimicrobials has not been well characterized. In this study, compost windrows were prepared using manure collected from cattle (Bos Taurus L.) fed tylosin (TY), chlortetracycline-sulphamethazine ...

  • Development of time-temperature probes for tracking pathogen inactivation during composting

    Pathogen inactivation is expected to occur in compost if temperatures over 55°C (131°F) are maintained for at least 3 days, or 15 days in windrows. However, a literature review revealed pathogen survival in a significant number of processes appearing to meet the prescribed time-temperature criteria. It was hypothesized that pathogen survival may be due to the existence of undetected temperature ...

  • Pragmatic farm composters forge new path to resource recovery

    AG CHOICE is an on-farm composting operation located in the scenic countryside of Andover, New Jersey. On the drive to tour their site, it was astounding just how much of New Jersey, our most densely populated state, is still rural. Jay and Jill Fischer operate the two-year-old facility, which is one of a kind in New Jersey. Jay also owns and operates a sawmill in the area, and it was while ...
