  • Government decides not to increase incinerator bottom ash tax

    The Treasury is dropping its proposals to increase the rate of landfill tax paid on incinerator bottom ash. Last year (April 2009), the Treasury launched a consultation entitled Modernising Landfill Tax Legislation and proposed to tax incinerator bottom ash at the higher rate for active waste, which is currently £48 per tonne, as opposed to the lower rate for inactive waste which is currently ...

  • Recovering and recycling phosphorus from incinerated waste

    Phosphorus can be extracted in viable quantities from fly ash, a by-product created when municipal solid waste is burnt in incinerators, according to research conducted in Sweden. Sufficient phosphorus could be recovered from the country’s incinerators to meet 30% of the Swedish annual demand for mineral fertilisers, say the researchers. A substantial amount of municipal solid waste (MSW) ...

  • Soaring demand for metals calls for rethink of recycling practices, says international resource panel

    The growth in demand for metals, which could see needs rise by almost ten times current levels, calls for a rethink of recycling practices in order to address negative environmental impacts, according to two reports released today by the UNEP-hosted International Resource Panel. Launched during a high-level dialogue on Resource Efficiency and Sustainable Management of Metals in Berlin, ...

  • New incineration-waste clean-up method brings resource and carbon benefits

    Ash from waste incineration can be made safer simply by mixing it with rice husks, water and other forms of waste ash at temperatures under 100 °C, according to new research. Once dried, the end product not only locks away toxic metals lead and zinc, but also stores carbon. Furthermore, it can be used in the polymer industry to lower costs, improve polymer properties and reduce the use of ...

  • The Greening of Civil Infrastructure

    Across many industries, manufacturers turn out the countless products we rely on in our daily lives. These processes also create something else: waste — lots of it. According to the U.S. Environmental Protection Agency, industrial facilities in the United States generate 7.6 billion tons of nonhazardous waste annually.1 To help keep this waste from ending up in landfills, many leading ...

  • EPA Cuts Mercury and Hydrocarbon Emissions for New Portland Cement Production

      The U.S. Environmental Protection Agency announced new emission limits for cement kilns that will help cut annual emissions of mercury and hydrocarbons. These limits will help protect public health from mercury and total hydrocarbon emissions from portland cement kilns, through amendments to an air toxics standard issued on Dec. 8, 2006. The amendments set mercury and hydrocarbon emission ...

  • Milestone project demonstrates innovative mercury emissions reduction technology

    An innovative technology that could potentially help some coal-based power generation facilities comply with anticipated new mercury emissions standards was successfully demonstrated in a recently concluded milestone project at a Michigan power plant. Under a cooperative agreement with the U.S. Department of Energy’s (DOE’s) National Energy Technology Laboratory (NETL), WE Energies demonstrated ...

  • EU exporting more waste, including hazardous waste

    Waste is increasingly moving across EU borders, for recovery or disposal. This is true for waste shipments between EU countries, and also transfers of waste outside the EU, according to a new assessment from the European Environment Agency (EEA). Increasingly stringent and harmonised waste policies in the EU have led countries to transport more waste material elsewhere, for example if ...

  • Waste-to-Energy - A burning issue for tomorrow`s cities

    Long considered a costly problem, municipal solid waste is now emerging as an important revenue-generating feedstock for waste-to-energy systems. As municipalities look to improve energy efficiency and reduce greenhouse gas emissions as part of their sustainability planning initiatives, new and innovative methods for burning wastes to generate heat and power are emerging. And while, at first ...
