  • Soil Flushing

    Introduction In situ soil flushing is the extraction of contaminants from the soil with water or other suitable aqueous solutions. Soil flushing is accomplished by passing the extraction fluid through in-place soils using an injection or infiltration process. Extraction fluids must be recovered from the underlying aquifer and, when possible, they are recycled. Cosolvent Enhancement Cosolvent ...

  • Reusing Recycled Tires: 5 Benefits of Recycled Rubber Retaining Blocks

    According to the Recycled Times, over 300 millions used truck and car tires are accumulated every year. At least 25% of those tires are being put into landfills, which means that every year in the U.S., 75 million tires are taking up space in a landfill when they could be reused for something better. To put this information into perspective, for every three people in the United States, there is ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • Compost integral in new website in building soil

    A website called “BuildingSoil” has been launched by the Washington Organic Recycling Council to help builders preserve healthy soil on building sites. It's the latest Soils for Salmon project which aims to change standard site development practices.

  • Connections: Understanding Urban Soil Lead

    There is no such thing as unleaded when talking about soils in urban areas. If a car had ever been driven near or paint had been applied to a home built on the soil prior to 1975, that soil will have measurable concentrations of lead. It can be detected in soils at the subparts per million range. Lead can cause developmental delays and reduced mental capacity. In short, lead is bad. But does a ...

  • Next frontier of organics recycling in California

    In California, we’re understandably proud of our tremendous success in recycling and reuse. Committed communities, enlightened businesses, and individual households have embraced the recycling ethic so vigorously that daily per person disposal has plunged from 8.4 pounds to 4.4 pounds. Such lofty achievement begs the question: What is the next frontier in recycling? The answer is simply ...

  • Wallboard goes green as firms recycle gypsum

    Gypsum wallboard — the ubiquitous material found in homes, offices and other buildings — is finding new life when recycled as a soil additive, especially for farm crops. Rather than seeing wallboard being dumped in landfills, companies such as Quality Soil Amendments (QSA) in California and Agri Marketing, Inc., in Pennsylvania have built successful businesses recycling drywall, then reselling ...

  • Impact of organic residues on soil microorganisms

    It is well known that organic residue amendments to soil give beneficial effects such as provision of plant nutrients, increased humus content and thereby increased water holding capacity, improved structure and increased cation exchange capacity. Organic wastes can be a valuable fertiliser in terms of phosphorous. Chemical precipitation in the sewage treatment plant makes sewage sludge rich in ...

  • Biosolids increase soil aggregation and protection of soil carbon five years after application on a crested wheatgrass pasture

    Biosolids application to rangelands and pastures recycles nutrients and organic matter back to soils. The effects of biosolids (20 and 60 dry Mg ha–1) and N+P fertilizer on soil aggregate stability, bulk density, aeration porosity, and total C and N of stable aggregates were evaluated 4 and 5 yr after surface application to a crested wheatgrass [Agropyron cristatum (L.) Gaertn.] pasture in the ...

  • Recycling asphalt shingles a boon for Minnesota C&D Recycler

    The Northeast Recycling Council estimates that more than 11 million tons of asphalt shingles are scrapped in the U.S. each year; 10 million from installation tear-offs and re-roofing jobs and another one million discarded as waste by asphalt shingle manufacturers. The U.S. Environmental Protection Agency estimates that shingle waste makes up 8 percent of the total building-related waste stream ...

  • Common Treatment Technologies for Inorganics in Soil, Sediment, and Sludge

    The most commonly used treatment technologies for inorganics in soil, sediment, and sludge include solidification/stabilization (S/S), excavation and off-site disposal, and acid extraction. These treatment technologies are described briefly below. Solidification processes produce monolithic blocks of waste with high structural integrity. The contaminants do not necessarily interact chemically ...
