  • Application of leachate pollution indices for assessment of leachate pollution potential of landfills (a case study of an unlined landfill with lime sludge and fly ash)

    Leachates from unlined landfills cause environmental degradation and health hazards due to resultant ground water pollution. Their pollution potential can be measured on a comparative scale using leachate pollution index (LPI). The selection of index involves 18 pollution parameters, their weightages and the sub–index values. The concentrations of pollutants are obtained from toxicity ...

  • What are the treatment options for landfill leachate?

    New contributor to Water/Waste Processing aims to answer readers’ most pressing questions It’s said the United States has 1,654 landfills, handling more than 250-million tons of trash each year. One Washington landfill covers a 2,545-acre area, has a 120-million-ton capacity and a 40-year expected trash-receiving life. The facility, the Republic ...

  • Comparison of phosphorus recovery from incineration and gasification sewage sludge ash

    Incineration of sewage sludge is a common practice in many western countries. Gasification is an attractive option because of its high energy efficiency and flexibility in the usage of the produced gas. However, they both unavoidably produce sewage sludge ashes, a material that is rich in phosphorus, but which is commonly landfilled or used in construction materials. With current uncertainty ...

  • Technical Note: An effective thermal technology for the detoxification of MSW fly ash

    Increasing public concern regarding potential health problems due to improper waste disposal practices and the introduction of landfill taxes have induced the practice of incineration. Presently, all UK incinerators have to meet very strict emission levels. The municipal solid waste (MSW) fly ash generated has to be managed very carefully as it is enriched with toxic organic micro pollutants and ...

  • 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 ...

  • Particle size distribution and dissolution properties of metals in cyclone fly ash

    The particles in the examined cyclone fly ash were all smaller than 0.25 mm. in diameter, and particles smaller than 0.075 mm. in diameter accounted for 88.4 % of the ash weight. This result indicates that cyclone fly ash consists of particles with a small diameter. The metals in the cyclone fly ash were enriched in small ...

  • Use of sewage sludge ash (SSA) in the production of cement and concrete - a review

    The use of recycled sewage sludge ash (SSA) in Portland cement and concrete has attracted a lot of global interest due the increase in sludge production and the limitation of land availability where it is used as a soil conditioner. These are in addition to rising environmental concerns. The major components of SSA are SiO2, CaO, ...

  • Case study - High volume fly ash in the Madera project

    Located on a fully wooded 44-acre site in Gainesville, Florida, directly adjacent to the University of Florida campus, Madera consists of 80 lots being developed by Green Trust, LLC, and built by three builders. In the spring of 2002, selected builders were invited to participate in a presentation and meeting with the Florida Energy Extension Service (FEES) which spearheaded the project for the ...

  • Installation of a grout curtain at a hazardous waste landfill

    Abstract: An existing inactive hazardous waste landfill located in Niagara Falls, New York was exhibiting migration of contaminants due to lateral groundwater flow in the underlying dolomitic limestone bedrock. It was determined that the installation of a vertical barrier to redirect the groundwater flow around the landfill would be the key element in the abatement design. Further review ...

  • Transformations of syngas derived from landfilled wastes using the Gasplasma process

    Abstract The Gasplasma advanced conversion technology is able to efficiently produce a clean syngas and an environmentally stable vitrified product from historically landfilled materials. The syngas is rich in hydrogen and carbon monoxide and possesses high calorific value, and low residual tar levels. While this syngas has traditionally been considered only as a fuel source for power ...

  • Turning a Liability into an Asset: A Landfill Gas-to-Energy Project Development Handbook

    Each person in the United States generates about 4.5 pounds of solid waste per day almost one ton per year. Most of this waste is deposited in municipal solid waste landfills. As this landfilled waste decomposes (a process that may take 30 years or more), it produces landfill gas. Landfill gas contributes to the formation of smog and poses an explosion hazard if uncontrolled. Furthermore, because ...


  • Are incineration and landfills the answer to save us from the recycling crisis?

    For plastic recycling, this year hasn’t exactly been one of the best – what is to blame? Oil. Shockingly, it actually costs more to recycle old plastic than it does to make new in many ways. Petroleum prices have fallen so low, as low as 70% below the level in June 2014. This may be great for some – however with it has fallen the cost of Virgin Plastic which is made from ...
