Examples of fuels produced from biomass are biomethane, renewable natural gas (RNG), biogenic hydrogen, biokerosene, biomethanol, bioethanol and higher alcohols. However, in future, care must be taken to avoid the well-documented conflict between crops used for food and those used for fuel production. The bioeconomy strategy therefore calls for only using the biomass that cannot be used for producing food. Microalgae, biowaste and residual materials have huge potential in this area.

    In order to achieve the sought-after shift towards sustainable regenerative energy supply, researchers around the world are focusing on the conversion of solar energy into hydrogen and carbon compounds using artificial chemical systems. They aim to achieve much more efficient photosynthesis than plants have. Other scenarios foresee improving the energy balance of photosynthesis by modifying the photosynthesis system.

    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.

    Grass flowers and small bushes are constant features along roadsides they are mowed at regular intervals and either dumped left where they are or less frequently composted. Cuttings like these could contribute to solving the global energy problem and even generate money. However communities that are aiming to turn green waste from roadsides riversides or sports grounds into biogas and hence a renewable source of energy are confronted with…

    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…

    Professor Bernhard Schink from the University of Konstanz has been focused on different aspects of the interaction of fermenting bacteria and methanogenic archaea for more than 25 years. Archaea have the unique ability to produce methane at the threshold of viability. The biologists research group is seeking to obtain insights into how prokaryotes such as those found in Lake Constance sediments are able to survive under anaerobic conditions.…

    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…

    In view of the changing climate and the finiteness of fossil resources, research into renewable energies is gaining in importance. One of the things that researchers have been looking into for quite some time is different possibilities to use organic wastewater compounds as sustainable energy sources. Carsten Meyer from the University of Stuttgart works on the generation of alternative energy sources. Together with his team of researchers, Meyer…

    Microorganisms and sensitive cells that are grown in bioreactors need a well-regulated environment and a food supply in order to do what they are supposed to do: grow and produce biomass and metabolites. Many fermenters are equipped with sensors that continuously measure critical bioprocess parameters, including temperature, pH value and oxygen. Online glucose and ethanol sensors are not yet used in regulated bioreactors, even though they would…
