  • Estimating national landfill methane emissions

    This paper estimates national methane emissions from solid waste disposal sites in Panama over the time period 1990–2020 using both the 2006 Intergovernmental Panel on Climate Change (IPCC) Waste Model spreadsheet and the default emissions estimate approach presented in the 1996 IPCC Good Practice Guidelines. The IPCC Waste Model has the ability to calculate emissions from a variety of solid ...

  • Utilisation of landfill gas for the generation of energy

    The gases in landfill sites that develop during degradation processes, largely contribute to the greenhouse effect and additionally harbour considerable safety and health hazards. However, they are also often rich in methane and therefore a potential energy carrier. In many countries much of this potential for the generation of electricity and heat from landfill gas still exists. Furthermore, ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Major Considerations in Landfill Closure

    Preparing for the closure and long-term care of a municipal solid waste landfill (MSWLF) can be an inordinate undertaking. Whether public or private, all landfills eventually reach the end of their active lifecycle. Before closure, a landfill must meet a series of criteria as determined by Subtitle D of the Resource Conservation and Recovery Act (RCRA). Following closure, those same regulations ...

  • Reduction in greenhouse gas emissions from sewage sludge aerobic compost in China

    Sewage sludge is an important contributor to greenhouse gas (GHG) emissions and the carbon budget of organic solid waste treatment and disposal. In this case study, total GHG emissions from an auto-control sludge compost system, including direct and indirect emissions and replaceable reduction due to sludge compost being reused as fertilizer, were quantified. The results indicated that no ...

  • Update on Federal Air and GHG Regulations Affecting Landfills

    EPA’s recent regulatory changes are expected to alter the way landfills are regulated for the foreseeable future with a potential to add additional compliance costs for the industry.  The air quality and greenhouse gas (GHG) regulatory framework at the federal level is currently in a state of flux with respect to landfills. The landfill industry awaits the issuance of a revised ...

  • Methane emission estimates using chamber and tracer release experiments for a municipal waste water treatment plant

    This study presents two methods for estimating methane emissions from a waste water treatment plant (WWTP) along with results from a measurement campaign at a WWTP in Valence, France. These methods, chamber measurements and tracer release, rely on Fourier transform infrared spectroscopy and cavity ring-down spectroscopy instruments. We show that the tracer release method is suitable for ...

  • How to define additionality in relation to greenhouse gas (GHG) reductions

    Companies that have facilities which use refrigeration and air-conditioning systems or heating, ventilation and air conditioning systems have to measure changes which are imposed upon them due to greenhouse gas emissions. Additionality is a measure which compares the level of emissions prior to implementation with the levels after a greenhouse gas reduction project has been introduced. ...

  • Bioenergy and greenhouse gases

    Branches, stalks, and manure are waste no longer; bioenergy is part of the solution to reducing greenhouse-gas emissions. A study released by the Green Power Institute, the Renewable Energy Program of the Pacific Institute, reports that converting forest residues, agricultural and urban biomass waste, and gases from manure and landfills into energy helps reduce our greenhouse-gas emissions and ...

  • Recycling, waste-to-energy to play an important part in reducing CO2

    More recycling and waste-to-energy programmes will reduce net greenhouse gas emissions. This is the conclusion of three recently published studies. A new briefing released by the European Environment Agency (EEA) states that: “Increased recovery of waste and diverting waste away from landfill play a key role in tackling the environmental impacts of increasing waste volumes. As recycling and ...

  • Carbon offsets from organic waste conversion projects

    The Climate Act ion Reserve (the Reserve) has long had a protocol to give credit for the capture and destruction of methane emissions from organic waste in landfills, but they have now opened up the possibility of credits for projects that prevent that waste from entering landfills in the first place. In October 2009, the Reserve adopted the Organic Waste Digestion Project Protocol, covering both ...

  • Recycling and Waste-to-Energy in combination for sustainable waste management

    More recycling and Waste-to-Energy (WtE) will reduce net Green House Gas emissions. This is the conclusion of several studies: The European Environment Agency states1:“Increased recovery of waste and diverting waste away from landfill play a key role in tackling the environmental impacts of increasing waste volumes. As recycling and incineration with energy recovery are increasingly used, ...

  • The Role of Eucalyptus Globulus Forest and Products in Carbon Sequestration

    Abstract This study is a contribution to the ongoing debate about the selection of the approach for carbon accounting in wood products to be used, in the future, in the national greenhouse gas inventories under the UNFCCC (United Nations Framework Convention on Climate Change). Two accounting approaches are used in this analysis: the stock-change approach and the atmospheric-flow approach. ...

  • Composting releases less air pollution than previously thought - study

    A new study funded by the California Integrated Waste Board (CIWMB) indicates that well-managed composting of green waste and food waste releases significantly less air pollution than previously thought. The study also demonstrates that a relatively inexpensive management technique - covering active compost piles with a layer of finished compost - may lower air emissions even further, by as ...

  • Composting - Best bang for MSW management buck

    For many years, life cycle analyses of end-of-life management practices have been available for all of the basic recyclables as well as organics. The life cycle data, usually derived by the US Environmental Protection Agency's Waste Reduction Model (WARM), represents the net greenhouse gas impact of recycling, landfilling or incinerating a variety of material streams. The model calculates ...
