  • 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 ...

  • 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, ...

  • 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 ...

  • Blending of would-be landfill turns out greener cement-based products

    The vision of a greener future for the construction industry motivates Andrew Dennis, an architect here who founded a company dedicated to producing environmentally friendly cement-based products. Instead of the heavy aggregates found in standard concrete, the materials made by GigaCrete Inc. include non silica based sands and byproducts of coal combustion, fly-ash and bottom-ash and recycled ...

  • AutoPumps Manage Landfill Leachate to Keep Methane Flowing - Case Study

    Green Bay adds Gas-to-Energy Facility to 30-year-old Landfil Brown County East Landfill in Green Bay, Wisconsin recently completed a feasibility study that determined it would be economically sound to convert methane gas into electrical energy by electric generators to the site. Two new Cat 3516A+ engines are projected to come on line in December of this year, housed in a new 30 x 100 ...

  • 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 ...

  • Recycling Vs. Landfills and Incinerators – Do Benefits of One Outweigh the Other?

    Believing the 2011 survey results of the U.S Environmental Protection Agency (EPA), the American nationals generate more than 240 million tons of waste every year. Often referred to as Municipal Solid Waste, this waste originates from households, schools, hospitals, and business establishments. This trash material often finds its place in the wasteland, where it is either recycled, trapped in a ...

  • Column studies aiming at identification of suitable filter materials for pollutant removal from landfill leachate

    Landfill leachate contains a complex mixture of inorganic and organic pollutants, which need to be removed before they pollute the environment. Different filter media (peat mixed with either carbon-containing ash, polyurethane waste, or wood pellets) were investigated with respect to their possibility to simultaneously and at low initial concentrations remove metals, polar and non-polar organic ...

  • Application of radiomagnetiotelluric method case study

    Investigations of the landfill of industrial wastes by the RMT method The test site is the landfill of the coal ashes from power plants. The landfill was closed about 5 years ago. Material of the landfill is represented by powder-like particles and granules with the cross sizes from several millimeters up to the first centimeters. Wastes fill in a V-shaped valley of a stream (Fig. 1). The ...

  • Heavy metals in wet scrubber residue from a medium–sized (32 MW) municipal district heating plant incinerating wood and peat in a fluidised bed boiler

    Due to the low total concentrations of heavy metals and extractable compounds, it is recommended that the wet scrubber residue be used as a construction agent instead of being disposed of in landfills. According to five–stage sequential extraction, the highest concentrations of most of the heavy metals occurred in the residual fraction (i.e., HF + HNO3 + HCl), which means that ...

  • The use of thermal plasma technology for treating air pollution control residues

    Energy from waste (EFW) is an exciting industry to be in right now in the UK. As pointed out by Euston Ling and Dr. Adam Read's article "The Shifting Landscape for Renewable Energy in the UK" {Waste Advantage Magazine, June 2011), the EFW capacity in the UK is set to grow strongly in the next 10 years, with some commentators predicting a three-fold increase in EFW capacity from the current 4 ...
