  • Assessing Feasibility of Direct Drive Technology for Energy Recovery from Digester Biogas

    ABSTRACTThe Regional Municipality of Waterloo completed a study, with support from Environment Canada, to evaluate the feasibility of using direct drive technology to recover energy from digester biogas. The study identified that a 150 HP engine, operating at 54 % load, could be supported by the estimated gas production of 1560 m3/d with 63 % methane by volume. ...

  • The feasibility of trace element supplementation for stable operation of wheat stillage-fed biogas tank reactors

    The aim of this study was to investigate the effect of trace element supplementation on operation of wheat stillage-fed biogas tank reactors. The stillage used was a residue from bio-ethanol production, containing high levels of sulfate. In biogas production, high sulfate content has been associated with poor process stability in terms of low methane production and accumulation of process ...

  • Ethanol by-product raises biogas output

    In 2007, the City of Fergus Falls, Minnesota undertook a study to evaluate adding thick corn stillage to the anaerobic digesters at its wastewater treatment plant (WWTP). The goal was to determine the potential for codigesting syrup with biosolids to increase biogas production, while avoiding operational and regulatory problems. The Fergus Falls WWTP operates three digesters in series, two ...

  • High-strength wastes boost biogas production

    Water and wastewater treatment plants (WWTP) are significant consumers of energy. The U.S. Environmental Protection Agency estimates the industry uses the equivalent of 56 billion kilowatt hours (kWh) of electricity, representing three percent of the nation’s energy consumption, and is responsible for creating 45 million tons of greenhouse gas emissions each year. Energy intensive processes, such ...

  • Spatial diffusion of biogas technology in Switzerland: a GIS-based multi-agent simulation approach

    In this paper, we study the viability and spatial diffusion of agricultural biogas technology in Switzerland by means of a multi-agent simulation model. The simulation process displays the estimated dissemination of biogas technology in the different regions of Switzerland over the period from 2006 to 2025, taking the varying circumstances for biogas use in each region explicitly into account. ...

  • Biomethane enters the gas grid article for energy world

    The Carbon Plan, published in 2011, aims to reduce UK carbon emissions by a quarter from 1990 levels. With the current policies in place, the UK is on target to reduce emissions by over a third by 2020 and with the introduction of new technologies this should increase to an 80% reduction by 2050. However, currently around half the UK’s carbon emissions result from heat related processes and ...

  • Empowering Alberta: Pioneering spirit gives boost to province`s alternative energy projects

    While biofuels are getting plenty of attention these days, biorefining - the process of converting biomass into biofuels and bioproducts that may also produce energy - is evolving. It's now at a point where organizations such as Alberta Life Sciences Institute, Alberta Agricultural Research Institute and the Alberta Forestry Research Institute are focused on positioning the provinces as a global ...

  • The whey to renewable energy

    When Tom Wilson with the Pennsylvania State University Cooperative Extension set out to study the feasibility of a community-based anaerobic digester in Mercer County, he initially analyzed processing manure collected from area dairies and food wastes gathered from the local college, nearby prisons and industrial food processors. But the economics of transporting the materials just did not make ...
