sewage methane gas emissions News

  • 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 ...

  • Cambi converts Beijing’s sewage sludge to clean energy and organic fertiliser

    Norwegian Prime Minister Erna Solberg opened last Friday in Beijing a new biogas plant, which uses Cambi’s thermal hydrolysis process at the XiaoHongMen wastewater treatment plant. Cambi is building five large plants in Beijing, producing energy from the sewage sludge from more than 20 million people in an environmentally sustainable, yet profitable way. Cambi’s ...

  • Cities launch global alliance to lower carbon emissions

    More than 2,000 cities have banded together in what the UN calls the largest effort by cities so far to curb their greenhouse gas emissions. The goal of the Compact of Mayors is to reduce greenhouse gas emissions by 454 million tonnes a year by 2020 — equivalent to the carbon dioxide emissions from 130 coal power plants — ...

  • 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 ...

  • WELTEC Optimises Wastewater Plants

    In the future, the anaerobic fermentation and utilisation of sludge from wastewater plants will play an increasingly important role. To ensure an economically and ecologically sustainable solution, more and more municipalities decide to optimise the energy potential of their sewage plants. For a plant dimension of 20,000 to 30,000 PE (population equivalent), biogas plant manufacturer WELTEC ...

  • WELTEC BIOPOWER Upgrades Municipal Wastewater Treatment Plant in Bavaria

    The increasing restriction of the agricultural use of sewage sludge is associated with mounting pressure on municipalities and sewage treatment providers. Moreover, the high power needs drive up the expenses of wastewater treatment plants. Thus, more and more sewage treatment plants decide to employ energy-saving sludge stabilisation in an anaerobic reactor and utilisation of the digestion gas ...

  • OFT recommendations will help anaerobic digestion

    ADBA Chairman and Lib Dem peer Lord Redesdale has welcomed the publication today [Thursday] of the OFT’s Market Study into Organic Waste. The Market Study was prompted by the water regulator Ofwat, to explore what barriers exist to competition in the treatment of sewage sludge, and the involvement of Water and Sewage Companies in the treatment of other organic waste. ADBA has been ...

  • Shrinking New York City`s carbon footprint

    St. Mary's Recreation Center in the Bronx was the first indoor recreation facility to open in New York City in 1951. Now the aging building is about to receive energy-saving retrofits to fix outdated heating and cooling systems, insufficient ventilation, and windows and doors that leak heat in the winter and cooled air in the summer. The New York City Parks Department facility is just one of the ...

  • Often-overlooked yet potent pollutant nitrous oxide poses Ozone and climate risks, UN warns

    Emissions of nitrous oxide (N2O), an often-overlooked yet potent gas, could nearly double by 2050 and thus potentially undermine gains in the ozone layer recovery and exacerbate climate change. Drawing Down N2O to Protect Climate and the Ozone Layer, a new report by the UN Environment Programme (UNEP), warns that nitrous oxide is now the most important ozone-depleting emission and the third most ...

  • Major advance made in generating electricity from wastewater

    Engineers at Oregon State University have made a breakthrough in the performance of microbial fuel cells that can produce electricity directly from wastewater, opening the door to a future in which waste treatment plants not only will power themselves, but will sell excess electricity. The new technology developed at OSU can now produce 10 to 50 more times the electricity, per volume, than most ...
