  • Pyrolysis of low-density polyethylene using synthetic catalysts produced from fly ash

    Catalytic pyrolysis of low-density polyethylene (LDPE) was investigated using various fly ash-derived silica–alumina catalysts (FSAs). FSAs were prepared by a simple activation method that basically includes NaOH treatment of fly ash by a fusion method, followed by an aging process. A series of LDPE pyrolysis experiments was conducted and the catalytic performance of FSAs was assessed in terms of ...

  • Assessment of Trace‐Element Impacts on Agricultural Use of Water from the Dan River following the Eden Coal Ash Release

    Catastrophic events require rapid, scientifically sound decision‐making to mitigate impacts on human welfareandthe environment. The objective of this study was to analyze potential impacts of coal‐ash‐derived trace elements on agriculture following a 35,000‐tonne release of coal ash into the Dan River at the Duke Energy Steam Station in Eden, NC. We performed scenario calculations to assess ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • `Evaluation of Strategies for Mercury MACT Compliance,` presented at the Coal-Gen 2004 conference

    Introduction On December 15,2003, the United States Environmental Protection Agency (U.S. EPA) proposed a rule with two alternatives to permanently reduce mercury (Hg) emissions from power plants. Under one alternative, which is the focus of this paper, the utilities would install controls known as Maximum Achievable Control Technologies (MACT) under section 112 of the Clean Air Act (CAA). ...

  • Pathogen destruction and solids decomposition in composting latrines: study of fundamental mechanisms and user operation in rural Panama

    The relationship between temperature, high pH, desiccation, decomposition, pathogen destruction, and user operation in active double vault urine diverting (DVUD) composting latrines located in the Bocas del Toro region of Panama was assessed. Latrine samples were analyzed for temperature, pH, % moisture, carbon-to-nitrogen (C/N) ratio, and presence of specific pathogens. Surveys and visual ...

  • Measurement of Trace metals in Ambient air case study

    Trace metals are found at low concentration in the ambient environment and are associated with adverse health effects. The gold standard metal measurement is Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES); however, sample preparation is laborious and expensive. The Xact 625 metals monitor uses non-destructive X-ray fluorescence technology. A built-in sample collection system ...

  • Estonia eager to teach world about oil shale

    AUVERE, Estonia (AP) — Home to the creators of Skype and the first country to use online voting, Estonia relishes its image as a technological pioneer. But the tiny East European country's most far-reaching economic achievement could come from how it has learned to squeeze oil from a rock. About 200 feet (60 meters) below ground in northeastern Estonia, very close to the Russian border, ...
