Common Treatment Train for Explosives
In general, no single technology can remediate an entire site. Several treatment technologies are usually combined at a single site to form what is known as a treatment train. A system diagram of a common treatment train for explosives is illustrated below. Explosive contaminated soil is first excavated from the site and transported to a windrow composting site. During windrow composting, ...

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 ...

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 ...

Chemical and physical properties of rice straw waste and hospital sewage sludge in turned windrow aeration system
In this paper, we present the main goal of optimum quality ratio of co-composting with rice straw waste and hospital sewage sludge. The experiments were designed by varying the initial C/N ratio and moisture content in the range of 25-45 and 30-70% w/w., respectively. The results clearly showed that the losses of Kjeldahl-N increased when the amounts of sludge in the mixtures were increased. The ...

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 ...

Occupational hygiene at a drum composting plant in Hyvinkää, Finland
Refuse disposal and treatment must be safe for employees. Organic dust of waste origin, perhaps containing microbes, may be harmful to health. Microbes, especially fungi but also thermophilic Actinomycetes bacteria, may cause allergy and asthma (Terho et al. 1993; Madigan et al. 1997). Usually fungi cause hypersensitivity (Madigan et al. 1997) and the most common syndrome is allergic rhinitis ...

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 ...
