    wusoa GmbH: What shall we do with manure? Liquid manure for decentralized small-scale biogas plants.

    Biogas has become an alternative and sustainable energy resource. In 2013, the 7,850 biogas plants in Germany – including 858 in Baden-Württemberg – produced enough biogas to cover around seven percent of Germany’s total electricity needs. Martin Falger, managing director of wusoa GmbH in Stuttgart, explained in an interview with Sanja Fessl (BIOPRO) why he believes that small-scale biogas plants have a promising future. They expand the biogas…

    New technologies for using biogas as a balancing energy

    The microorganisms in biogas plants do a great job biologically converting CO₂ and hydrogen, which are primary fermentation products, into methane. Biomethane has a great future as an energy source. Scientists at the University of Hohenheim are investigating new ways to produce and use biomethane.

    Biogas and sustainability

    The German Renewable Energy Sources Act (EEG) has led to a considerable increase in the use of biogas in Germany. However, increasing biogas production must make ecological sense and not generate conflict with the sustainability objectives of environmental conservation schemes. There must therefore be a careful consideration of the overall conditions. An analysis of the ecological impact of the generation and use of biogas in Germany taking into…

    Flexible biogas plant operation – new concepts for stabilising bioenergy provision

    The lack of flexibility with regard to peak demand for electricity – both for consumers and producers – is a well-known problem as far as the production of electricity from renewable resources is concerned. Biogas plants present a particular challenge due to the complex and relatively slow microbial processes involved. A research project called FLEXIZUCKER at the Universities of Ulm and Göttingen aims to make biogas production more flexible and…

    Making money with waste – biogas

    At a time when energy crops are competing with food crops for agricultural land, the company n-bio GmbH is doing something positive by turning what is considered waste into bioenergy. This not only reduces waste disposal costs, but also protects the environment. The technically highly sophisticated waste fermentation plants manufactured by n-bio GmbH automatically remove packaging residues and are also able to cope with pralines. The company’s…

    Bioenergy villages: biogas sets the tone

    In 2011 Baden-Württemberg was home to around 37 bioenergy villages and several others are under construction or in the planning phase. Bioenergy villages produce all of their electricity and energy for heating locally from renewable resources such as maize and wood electricity is mainly generated from biogas.

    University of Stuttgart participates in EU project: Parameters that help advance biogas technologies in Europe

    There is a binding EU-wide target to source 20 per cent of each country’s energy needs, as stipulated in the Kyoto Protocol, from renewable sources by 2020. The production of biogas is one promising key technology that could lead to this target being reached. But which technologies, measures and conditions are needed to advance biogas technology in Europe? The EU research project SEBE (Sustainable and Innovative European Biogas Environment) is…

    The International Biogas and Bioenergy Competence Centre (IBBK) and its role in Baden-Württemberg’s bioeconomy

    The number of biogas plants in Germany has increased almost tenfold since the start of the new millennium1. IBBK Fachgruppe Biogas GmbH, founded in 2000, has helped shape this development through training, consulting services and projects. Since 2015, the company has also been working on behalf of the Baden-Württemberg government to advise operators of existing and planned biogas facilities.

    How efficient and climate-friendly is biogas production?

    Biogas plants have become a familiar sight in Baden-Württemberg's rural areas. It might therefore be expected that broad experience exists in the comprehensive evaluation of this type of energy generation from renewable resources or organic materials. However, scientists draw a very differentiated picture. It is difficult to make any generalisations, although the analysis of individual facets can provide further help.

    Pure biogas in three steps: University of Hohenheim develops new type of biogas plant

    Higher methane level, shorter process times, more flexible products: researchers from the University of Hohenheim are planning to establish a three-tier pilot plant over the next three years that is able to produce all this. In the long term, this will contribute to a reduction in the energy required to produce biogas relative to the energy currently required to produce natural gas and it will also enable biogas to be supplied via existing gas…

    In addition to sunlight water and wind biogas is a regenerative source of energy that contributes to saving fossil resources. Germany is home to around 7100 biogas plants including 796 as of 2011 in Baden-Württemberg. In 2010 these facilities produced 11 per cent of the electricity generated from renewables in Germany. Energy-rich methane is the major constituent of biogas and is produced when organic compounds are broken down by bacteria in the…

    Ecologists can drive forward biogas research too

    The biologist Prof. Dr. Marian Kazda from Ulm has worked on biogas research for many years. However, he occupies a particular niche in that he approaches the topic from the point of view of a problem-oriented ecologist. The 55-year-old is head of the Institute of Systematic Botany and Ecology at the University of Ulm and his specific field of research is plant ecology. It was his work on wetlands that first got him interested in biogas research.

    Algae are frugal organisms. They require only light, water, minerals and carbon dioxide to be able to produce biomass. These properties will now be exploited economically in a two-year research project. Dr. Stefan Sebök from the University of Hamburg plans to study the holistic utilisation of degradation products of a biogas plant in Wallerstädten by linking them to land-based algae cultivation.
