As pressure for new infrastructure and development grows, it is inevitable that building projects will encounter some of the c20,000 closed former solid waste landfills in the UK, many of which will have accepted municipal solid wastes (MSW). Construction on or across these sites brings a special set of geohazards associated with the potential for large and difficult to predict settlements, gas...

Portugal, with 210,422 tonnes of glass recycled in 2011, did not attain the target for glass (227,060 tonnes), and this happened probably due to three factors: the reuse of this material since glass is a durable material, non-declaration of glass received by MRF (Material Recovery Facilities) and nondeposition in the specific stream. In 2011 were produced in Portugal, 5.159 million tonnes of Mu...

The U.S. Environmental Protection Agency (EPA) and International Fuel Cells Corporation conducted a test to verify the performance of a landfill gas treatment unit and a phosphoric acid fuel cell system. The complete system removes contaminants from landfill gas and produces electricity for on-site use or connection to an electric grid. The verification test was the first use of fuel cell techn...

A solid waste management crisis exists in many parts of the US as a result of the inability to site new landfills to replace the consumed capacity of existing landfills. Municipal solid waste (MSW) landfills can, and usually do, have a significant adverse impact on the individuals who own property in, reside in, or otherwise use, areas near the landfill. This leads those who stand to be adverse...

The rate of methane production in municipal landfills is influenced by a large number of processes. The relevance of these various interacting processes can be evaluated on the basis of a mechanistic model. The aim of this research is to evaluate the relevance of environmental conditions (pH, temperature, moist content) on the methane production rate in municipal landfills. This evaluation is b...
