  • Investigation of benefit of using coal wastes in cement production

    Waste disposal in coal preparation plants leads to serious environmental problems. These wastes usually contain about 20% carbon, and the composition of the remaining ash is similar to clay. Addition of these wastes to cement clinker raw material utilises carbon as a source of energy. In this investigation, the effect of addition of these waste materials to the raw materials used in cement ...

  • Studies on coal flotation in flotation column using statistical technique

    Flotation of Indian high ash coking coal fines to obtain clean coal has been reported earlier by many authors. Here an attempt has been made to systematically analyse factors influencing the flotation process using statistical design of experiments technique. Studies carried out in a 100 mm diameter column using factorial design to establish weightage of factors such as feed rate, air rate and ...

  • The use of tetragnathid spiders as bioindicators of metal exposure at a coal ash spill site

    On December 22, 2008 a dike containing coal fly ash from the Tennessee Valley Authority Kingston Fossil Plant failed and resulted in the largest coal ash spill in U.S. history. This study was designed to determine sediment metal concentrations at multiple site locations and to determine if site‐specific bioaccumulation of metals existed in tetragnathid spiders. Selenium and nickel were the ...

  • Innovative fracture-resistant construction material from C&D waste aggregate, fly ash and recycled plastics

    A laboratory investigation was conducted to evaluate the fracture behaviour of an alternative pavement foundation material containing cement stabilised reclaimed crushed aggregate, Class C fly ash and waste-plastic strip (high density polyethylene or HDPE) reinforcement. The primary objective of using strip reinforcement was to improve the tensile strength, crack resistance and toughness ...

  • An economic feasibility model for ash use in flowable fill with integration of logistics and contaminant leaching factors

    Encasement of utility cables and pipes in flowable fill monoliths formed in trenches requires the use of materials that satisfy both strength and contaminant leachability limits. Coal combustion ash is often readily available for use in flowable fill construction. The use of ash in desirably large quantities, calls for the determination and selection of the maximum ash mix fraction that meets ...

  • Variation in riparian consumer diet composition and differential bioaccumulation by prey influence the risk of exposure to elements from a recently remediated fly ash spill

    Emerging aquatic insects play a key role in transporting aquatic nutrients and contaminants to riparian consumers. However, little is known about how within and between year variation in the diet or patterns of element bioaccumulation in emerging insect taxa may influence the risk of exposure to wildlife. During two breeding seasons, we examined the composition of the diet of tree swallows ...

  • Selenium bioaccumulation in fish exposed to coal ash at the Tennessee Valley Authority Kingston spill site

    In December 2008, 4.1 million m3 of coal ash were released into the Emory and Clinch Rivers by the Tennessee Valley Authority (TVA) Kingston Fossil Plant. Coal ash contains several contaminants, including the bioaccumulative metalloid selenium (Se). Because Se is predominantly accumulated in aquatic organisms through dietary, rather than aqueous exposure, tissue‐based toxicity thresholds for ...

  • Case study - High volume fly ash for the 2 Folsom project

    High Volume Fly Ash (HVFA) concrete was successfully used as the cornerstone of this project’s sustainability program. HVFA concrete was aggressively pursued because of its environmental benefits. When fly ash is used in place of cement, energy and landfill space is conserved and greenhouse gas emissions are reduced. During this HVFA project, roughly 2,800 tons of CO2 emissions were ...

  • Converting waste into valuable resources with the Gasplasma process

    Abstract This paper reports on a novel process development to convert waste into renewable energy using gasification. Advanced Plasma Power (APP) has developed an advanced thermal conversion technology, (Gasplasma ), capable of treating a wide range of organic and inorganic wastes. In the two-stage thermal process, the fluidised bed gasifier (FBG) converts the waste to a crude syngas ...

  • Case study - Fly ash for California’s Olivenhain dam

    The Olivenhain Dam will be the first roller compacted concrete (RCC) gravity dam in California and the tallest in North America. At 308 feet tall and 2,552 feet long, the dam used almost 1.5 million cubic yards of RCC and over 152,000 tons of fly ash. As the centerpiece of the San Diego County Water Authority (SDCWA) Emergency Storage Project, the dam is designed to survive a major earthquake and ...

  • Case study - Fort Mandan visitor services center

    The North Dakota Lewis & Clark Bicentennial Foundation has created a unique facility for one of the most vital sites on the Lewis & Clark Trail. The new visitor services center at Fort Mandan stands as a showcase for coal combustion products, while at the same time educating visitors about the journey of Lewis & Clark in North Dakota. Three major parts of the North Dakota: economy, ...

  • Legal lookout: competing coal ash proposals

    Depending upon comments the EPA gathers, industry may have to or not have to close out their coal ash containment ponds within five years. On May 4, 2010, EPA issued its long-awaited proposal to manage coal ash – the byproduct of burning coal to generate power. The agency proposed two quite different approaches for regulating coal ash, somewhat to the consternation of critics, who had hoped ...

  • How can we use Biomass as an energy source?

    Any Country which has Agriculture or Forestry waste available has big scope to use biomass as an energy source. We can use Biomass as fuel in its loose form but we can also bind them in solid fuel for more energy consumption.
