  • Green sewage plant could be powered by its own waste gas

    Engineers in the US are using rocket-thruster technology to create a self-powered sewage treatment process that also reduces greenhouse gas emissions.  Using microbes to break down sewage produces nitrous oxide and methane, which contribute to climate change. Now a team at Stanford University in Califronia hopes to increase production of these gases so the methane can be used as fuel and the ...

  • Jubilee bonfire beacon, but no explosion, thanks to methane leak check

    Villagers in Brightwell Baldwin in Oxfordshire celebrated the Queen's Diamond Jubilee in style, lighting a hilltop bonfire as one of the nationwide chain of 4000 beacons being lit simultaneously. But the organiser had a background in the gas industry, so he was nervous about lighting a fire above an old landfill site. Leigh Greenham, who has been involved in the gas detection business for many ...

  • Hey, Doc! Sewage, Beer and Food Scraps Can Power Chevrolet’s Bi-fuel Impala

    Trash to fuel, the stuff of the 1980s sci-fi comedy movie trilogy “Back to the Future,” is now a reality. The 2015 Bi-fuel Chevrolet Impala – not a tricked-out DeLorean – really can run on leftovers, table scraps and, oh, yeah, grains from brewing beer. Cleveland-based quasar energy group uses organic waste to produce a renewable energy source known as biogas, which ...

  • African river study fills gap in carbon emissions tally

    African rivers emit a vast amount of greenhouse gases, a major paper on this understudied topic reveals. As rivers carry organic matter from the land to the oceans, bacteria turn it into greenhouse gases. While previous analyses had quantified emissions of these gases from rivers in Brazil, Europe and North America, the study in the journal Nature ...

  • IFAT CHINA 2008 – Exploiting the energy potential of landfill gas

    No. 06/e March 2008 IFAT CHINA 2008 – Exploiting the energy potential of landfill gas The gases arising in decomposition processes in landfill sites contribute to the greenhouse effect and also present a substantial health hazard. On the other hand they are often rich in methane and therefore a potential energy source. In China there is still considerable potential for generating electricity and ...

  • Compost and climate change: a novel mitigation strategy?

    Native soils are thought to take up more of the greenhouse gas methane than land used for farming. This study shows that, while agriculture can exert an adverse impact on soil methane uptake, the application of soil conditioners like compost may compensate for loss of the methane sink function. The researchers propose new land management strategies based on this finding. Agriculture has become ...

  • Ameresco executes historic renewable energy contract

    San Antonio Water System’s (SAWS) Board of Trustees has approved a truly innovative contract with Ameresco, Inc. (Ameresco), which will take Biogas, a byproduct of the anaerobic digestion process from biosolids, containing 60 percent methane, and use it as a green energy source. Eighty percent of the city’s biosolids – the solids remaining after liquid waste is removed – are used to generate ...

  • Fact sheet on Biogas - An important renewable energy source

    “Biogas” is a gas produced by anaerobic fermentation of different forms of organic matter and is composed mainly of methane (CH4) and carbon dioxide (CO2). Typical feedstocks for biogas production are manure and sewage, residues of crop production (i.e., straw), the organic fraction of the waste from households and industry, as well as energy crops including maize and grass silage. ...

  • Biogas from byproducts gives the most environmental benefit

    Biogas made from byproducts is the vehicle fuel that offers the most environmental benefit. That’s the conclusion of research done by the Faculty of Engineering at Lund University, Sweden. “In the worst case the climate effect is reduced by 60 percent compared with diesel and petrol fuels,” says researcher Pål Börjesson. The results of the study were presented at a ...
