  • 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 ...

  • Anaerobic co-digestion of sewage sludge and primary clarifier skimmings for increased biogas production

    The objective of the study was to identify the impact of co-digesting clarifier skimmings on the overall methane generation from the treatment plant and additional energy value of the increased methane production. Biogas production from co-digesting clarifier skimmings and sewage sludge in pilot-scale fed-batch mesophilic anaerobic digesters has been evaluated. The digester was fed with ...

  • Biogas in Asia

    The development of biogas production and monitoring has had many twists and turns, from its early days in Germany to the heady days of support through the Clean Development Mechanism (CDM).   The fall in the price of carbon credits, which rewarded reduction in emissions of methane (CH4) - a potent greenhouse gas - and use of methane from waste as renewable energy, has hit Asia ...

  • 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 ...

  • Potential biogas production from sludges and msw in Uruguay

    Sewage treatment Montevideo's sewage is disposed into the sea by means of an outfall. Nevertheless as there are a lot of cities that are not on seashore, and most of these cities are discharging their effluents into rivers without proper treatment, a more strict sewage treatment must be done in order to achieve the discharge standards. For the 1,780,000 inhabitants the current sewage coverage is ...

  • Increased biogas production in a wastewater treatment plant by anaerobic co-digestion of fruit and vegetable waste and sewer sludge – A full scale study

    Anaerobic digestion is a well established technology for the reduction of organic matter and stabilization of wastewater. Biogas, a mixture of methane and carbon dioxide, is produced as a useful by-product of the process. Current solid waste management at the city of Prince George is focused on disposal of waste and not on energy recovery. Co-digestion of fresh fruit and vegetable waste with ...

  • Energy from biogas

    From an ecological and economical perspective, biogas is an important source of energy. The fossil resources are limited, and they impose a high burden on the environment. A resourceconserving alternative made from biomass poses a different scenario. The raw material is renewable, and conversion only releases as much CO2 as was previously contained by the source material. With the technological ...

  • Utilization of poultry, cow and kitchen wastes for biogas production: a comparative analysis

    During the past two decades, developing countries and particularly Nigeria has witnessed increased level of waste generation due to population explosion, increased agricultural activities, and the growth of industries. Consequently, there is intense scrutiny of possible alternative of solid waste utilization through biogas production using organic residues, which includes poultry droppings, ...

  • Stimulation of the hydrolytic stage for biogas production from cattle manure in an electrochemical bioreactor

    Electrical current in the hydrolytic phase of the biogas process might affect biogas yield. In this study, four 1,150 mL single membrane-less chamber electrochemical bioreactors, containing two parallel titanium plates were connected to the electrical source with voltages of 0, −0.5, −1 and −1.5 V, respectively. Reactor 1 with 0 V was considered as a control reactor. The trend of biogas ...

  • The use of microalgae and their culture medium for biogas production in an integrated cycle

    Vinasse is a residue produced in large quantities as a sub-product of ethanol production. Anaerobic digestion of vinasse can yield large amounts of biogas, but often difficulties arise in maintaining stable operation, due to the acidity of the material (which has a pH between 3.5 and 5) and a strong tendency to further acidification. Anaerobically digested vinasse can be used as part of a ...

  • Going Further with Food: The Rise of Channelling Food Waste for Biogas Production

    Almost 50% of the total amount of food thrown away in the UK comes from our homes, representing over seven million tonnes of food and drink wasted from British households annually. Wasting this food costs the average household £470 a year. In fact, if we all stop wasting food that could have been eaten, the benefit to the planet would be the equivalent of taking 1 in 4 cars off the road ...

  • Easy payback from biogas monitoring

    There is a strong business case for biogas monitoring and CHP protection. A fixed biogas analyser may cost some £6-10,000 and monitor gas every few minutes day and night. By comparison it can save its own cost many times over by protecting CHP engines from expensive unplanned downtime, biogas engine ...
