contaminated soil composting Articles

  • 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 ...

  • Composting of petroleum contaminated soil case study

    Soils contaminated with hydrocarbons are generated during oil and gas production. Remediation by land treatment is a popular, inexpensive option however, in cold climates temperature limits the time available for treatment each year. Companies would prefer an economical, low maintenance treatment alternative which could operate throughout the year in cold climates. Environmental BioTechnologies, ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation.

  • 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 ...

  • 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 ...

  • Effects of biowaste compost amendment on soil microbial biomass and specific carbon turnover in agricultural soils

    The importance of biowaste compost as organic fertilisers has become more emergent in the last years due to the increased production of compost produced from biowaste. The utilisation of organic fertilisers in agriculture improves the physical, chemical and microbial properties of soils (Allievi et al., 1993; Senesi, 1989). Amendment of compost affects several soil properties positively like e.g. ...
