  • High solids anaerobic digestion of pfmsw using novel anaerobic reactors

    In the last decade efforts have been made to control anaerobic digestion of the putrescible fraction of municipal solid waste (PFMSW) in engineered reactors, than to allow for 'free' digestion in landfill sites. Such a process achieves enhanced treatment efficiency in significantly reduced retention times (from years down to days) and completes energy recovery from waste, without biogas emissions ...

  • Estimates of CO2 emissions reduction and potential power generation from biogas at Mare Chicose landfill

    In this study, the annual generation of Landfill Gas (LFG) and methane using the Scholl-Canyon model have been predicted for 1998-2030 for five scenarios of landfill management at the Mare Chicose landfill in Mauritius. Using the Approved Large-Scale Methodology AM003 and Approved Baseline Methodology AM0010 of the Approved Methodologies for CDM activities, the carbon dioxide (CO2) emissions ...

  • Biomethanation of solid wastes: analysis of case studies

    Management of the organic fraction of urban solid waste using anaerobic procedures will contribute to the reduction of greenhouse gas emissions, and using biogas, which is a carbon neutral energy, to generate electrical energy will eventually help in reducing the combustion of fossil fuel. Energy recovery in the form of biogas from Municipal Solid Waste (MSW) generated in three different ...

  • Analysis of greenhouse gas emissions from 10 biogas plants within the agricultural sector

    With the increasing number of biogas plants in Germany the necessity for an exact determination of the actual effect on the greenhouse gas emissions related to the energy production gains importance. Hitherto the life cycle assessments have been based on estimations of emissions of biogas plants. The lack of actual emission evaluations has been addressed within a project from which the selected ...

  • Anaerobic digestion as integrated part of a mechanical-biological Waste treatment process

    Anaerobic digestion as a means of stabilising residual municipal solid waste (RMSW) before landfilling was evaluated to study the stabilization of RMSW through mechanical-biological processes and evaluate the effect on landfills. The tests were at the site of WGV Recycling GmbH in Quarzbichl between September 1995 and March 1996. The trials, which were run with a single-phase anaerobic digester, ...

  • Nitrogen removal from digested manure in a simple one-stage process

    A process based on partial nitrification and recirculation into the anaerobic digester was studied to remove nitrogen from digested manure and thus reduce enhanced gaseous ammonia emissions due to on-farm biogas production. An anaerobic reactor representing an anaerobic manure digester was fed with a nitrite solution and digested manure liquor. Nitrite was efficiently removed from the influent ...

  • Development of a tool for improving the management of gaseous emissions in UASB-based sewage treatment plants

    This study aimed at developing a simple tool for improving the management of gaseous emissions in UASB-based sewage treatment plants (STPs), considering different scenarios for the management of sludge, biogas and gaseous emissions (especially sulfide and methane). For small STPs (<10,000 inhab.), simple alternatives for the use of biogas were considered (e.g. for excess sludge ...

  • Environmental and energetic benefits derived from the anaerobic digestion of agroindustrial wastes

    Agrifood industry plays a relevant role in the economic development of the autonomous community of Extremadura (Spain), and generates vast volumes of wastes featured by both high polluting potential and moisture content. The present work reports on a detailed analysis of biogas generation from the anaerobic digestion of industrial tomato residues and slaughterhouse wastes, in this way, yields ...

  • Technology choices in scaling up sanitation can significantly affect greenhouse gas emissions and the fertiliser gap in India

    Nearly 800 million people in India lack access to adequate sanitation. The choice of technology for addressing this need may have important sustainability implications. In this study, we used life cycle assessment to compare environmental impacts and nutrient recovery potentials of four different options for providing everyone in India with access to improved sanitation: (i) centralised ...

  • On-road tests show gas trucks up to 5 times worse for air pollution

    Trucks powered by liquified natural gas (LNG) pollute the air up to five times more than diesel trucks, according to on-road tests commissioned by the Netherlands government. The results fly in the face of truckmakers’ claims that gas trucks cut nitrogen oxide (NOx) emissions by more than 30%.[1] [2] Transport & Environment (T&E), which today publishes ...

  • Determination of greenhouse gas emission reductions from sewage sludge anaerobic digestion in China

    Sewage sludge is a considerable source of greenhouse gas (GHG) emission in the field of organic solid waste treatment and disposal. In this case study, total GHG emissions from sludge anaerobic digestion, including direct and indirect emissions as well as replaceable emission reduction due to biogas being reused instead of natural gas, were quantified respectively. The results indicated that ...

  • How big is the distributed energy opportunity for water and wastewater utilities?

    Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of ...

  • Role of Gas Analysis in the Future of Biogas

    Although subject to fierce debate over the last few decades, there is now a global scientific consensus that the earth’s climate is warming at an unsustainable rate. Data gathered by Berkeley Earth, the Japanese Meteorological Agency, the Met Office Hadley Centre, NASA, and the NOAA National Climactic Data Centre shows a consistent trend of long-term global rising temperatures. With precise ...
