  • Sustainable cost reductions: biogas from liquid wastes - Case Study

    More and more dairies are now facing a problem: how to dispose of their liquid waste products. Spreading slurry is not a realistic option any more for the agricultural industry due to the problems of overfertilisation or hygiene. The challenge for dairies is that their liquid waste products generally have a very high organic load. Wastewater accumulates, typically, as a result of cleaning and ...

  • Sustainable cost reductions: biogas from liquid wastes

    Generate energy instead of consuming it: treating liquid wastes and wastewater on a communal basis to generate biogas is an interesting alternative to conventional wastewater treatment and disposal for dairies. This is becoming a serious consideration for the future for milk producers given the globally increasing challenges arising from wastewater regulations or CO2 guidelines. More and more ...

  • Fluidized bed drying system at Ara Region Bern AG, Berne, Switzerland - Case Study

    Fluidized bed drying system at ARA REGION BERN AG, Berne, Switzerland Already a leader in environmental sustainability, ara region bern ag (arabern) in Switzerland had an ambitious plan to produce renewable energy. Their plant has used digestion gas for heating processes in the wastewater treatment plant. But a new concept would take the plant’s energy efficiency and environmental ...

  • Increasing methane content in biogas and simultaneous value added product recovery using microbial electrosynthesis

    Electrosynthesis of multi-carbon compounds from the carbon dioxide present in biogas is a nascent approach towards purification of biogas. Microbial electrosynthesis (MES) cells, fabricated using different electrode materials, were operated using different electrolytes and mixed anaerobic culture as biocatalysts in the cathodic chamber under an applied cathode potential of −0.7 V vs standard ...

  • Basics Of Biogas Upgrading

    Several powerful incentives are driving biogas generators to consider upgrading their biogas to meet standards for pipeline injection and vehicle fuel markets. Producing renewable natural gas (RNG) can create opportunities to monetize lucrative RIN, or renewable identification number, credits under the federal Renewable Fuel Standard and generate carbon credits under state supported low carbon ...

  • Evaluation of the simultaneous biogas upgrading and treatment of centrates in a high-rate algal pond through C, N and P mass balances

    The simultaneous capture of CO2 from biogas and removal of carbon and nutrients from diluted centrates in a 180 L high-rate algal pond (HRAP) interconnected to a 2.5 L absorption column were evaluated using a C, N and P mass balance approach. The experimental set-up was operated indoors at 75 μE/m2·s for 24 h/d at 20 days of hydraulic retention time for 2 months of steady ...

  • Biogas cleaning / conditioning - A requirement for optimal functioning of CHP systems

    Biogas is obtained through the anaerobic decomposition (putrefaction) of organic matter. It contains methane (CH4) in varying proportions, ranging from 35% to 70%, a proportion which largely depends on production methods and the materials involved in the process. This methane concentration is what enables biogas to be used as fuel. The release of methane into the atmosphere contributes to an ...

  • The DMT Carborex® MS Small scale biogas upgrading plant

    Introduction As we are all aware, fossil fuels are depleting rapidly and the energy consumption is growing. Due to increasing fossil fuel prices other types of fuels become more interesting. Nowadays technology enables us to use renewable fuels in an economically profitable way. An easy technique to produce fuel is the digestion of green waste; sewage sludge, manure and agricultural ...

  • Portable biogas bottling plant: a practical approach for using biogas as transportation fuel in rural areas

    Biogas contains about 65% methane, 30-35% carbon dioxide, traces of hydrogen sulphide and moisture. It has been observed that diesel engines get severely damaged when operated on biogas for long duration. Presence of these corrosive gases make biogas unsuitable for transportation application. By removing CO2 and trace acidic gases like H2S and moisture, biogas can be converted into natural gas ...

  • Energy technologies for rural areas ? decentralised power generation through MARKAL modelling: a case study

    Due to shortage of power, extremely subsidised tariffs, poor financial recovery, long transmission lines, there exists a very poor demand-supply balance in the rural energy sectors of India. MARKAL bases analysis of a village-group in western India reveals that there is a potential of reducing the electricity demand by about 18% as compared to the business-as-usual case through adopting energy ...

  • From the biogas to vehicle fuel

    The biogas consists mainly of methane and carbon dioxide. Other components can be water and sulphur, mainlyhydrogen sulphide. To be able to use the biogas as vehicle fuel or to distribute it in natural gas grids the gas has to becleaned and upgraded. The biogas is upgraded by removing carbon dioxide to raise the calorific value and create a gaswith constant quality. One of the techniques to ...
