Pleasant aromas from biogas

Butyric acid is an important source of fruity aromas. It accumulates as an intermediary product during biogas production, from where it can be siphoned off and used for producing flavours. A new collaborative project aims to explore the technological and bioeconomic potential of extracting butyric acid from biogas plants.

75 percent decline in insects in parts of Germany

A recent study on the disappearance of insects is making headlines: it found that the insect biomass has declined by more than 75% in certain areas in Germany that were monitored by the study over a period of 27 years. The authors believe that the dramatic decline in insect biomass is down to industrial agriculture, which is therefore in conflict with certain bioeconomic principles: the sustainable cultivation of biomass and the safeguarding of…

Biomass from algae and the wholesale market – a promising replacement for fossil raw materials

Funding renewable energies is one of the EU’s key objectives. Biomass such as algae and organic waste are particularly promising because they are not in competition with food production. Scientists at the Fraunhofer IGB in Stuttgart ferment biomass from wholesale market waste and algae. They use a cascade process to obtain valuable materials and the biogas methane. Their aim is to close material cycles and achieve high efficiency and flexibility…

Microalgae – resource-saving raw materials for the food and feed sectors

Coal, petrol and natural gas are our energy sources and the basis for the food, pharmaceutical and chemical industries. However, the supply of fossil fuels is gradually running out. The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart has turned to microalgae in the search for alternative sources of energy. Initial pilot projects in which a variety of different methods based on state-of-the-art technologies were…

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…

Efficient production of fuel from biogenic residues

Natural gas is a more climate friendly fuel than raw materials such as coal and petroleum. Nevertheless it is also a fossil fuel that generates anthropogenic CO2 emissions. In a collaborative project at the Karlsruhe Institute of Technology, scientists and engineers are concentrating on finding out how biogenic residues and waste materials such as wood, sewage sludge and biomass mixtures can be turned into alternative gaseous fuels.

Forests as providers of ecosystem services – the facets and consequences of logging

One billion people worldwide rely on forests as living spaces. Illegal and legal deforestation endangers people’s livelihoods as well as social and economic structures. It also has a detrimental effect on the global climate. Prof. Dr. Daniela Kleinschmit, Professor for Forest and Environmental Policy at the University of Freiburg, discusses the causes and consequences of deforestation. She is co-editor of an international report on illegal…

Lignin – a natural resource with huge potential

Petroleum is the lifeblood of the chemical industry. It is the raw material for basic chemicals and is used to produce a tremendous wealth of products. Growing demand and dwindling resources mean that the chemical industry is increasingly focusing on renewable resources. Lignin is a wood component that is proving to be a particularly promising resource. It is currently almost exclusively used for generating energy, although it could also be used…

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.

Research focuses on lignin as an alternative to fossil resources

Along with cellulose, lignin is one of the most common organic compounds on earth. Researchers from the Fraunhofer Institute for Chemical Technology ICT are working on optimising the yield of aromatic platform chemicals using innovative sustainable processes for the extraction and fractionation of lignin. The ultimate goal is to provide an alternative to petroleum in the pharmaceutical, plastics and food industries.

Agroforestry for sustainable agriculture

Agroforestry systems can provide effective protection against soil erosion caused by wind and water. They can also contribute to stabilising and improving the yield of annual plants. In addition, strips in fields planted with shrubs and trees form living spaces and areas to which plants and animals can retreat. In the AUFWERTEN innovation group, the Fraunhofer Institute for Industrial Engineering IAO is working with other German research…

How Germany’s renewable energy supply targets can be achieved

In 2015, almost a third of Germany's electricity came from wind, sun and biomass. We need to continue reducing CO2 emissions to become even less dependent on fossil fuels such as coal and petroleum, and thus make electricity generation even more climate friendly. Baden-Württemberg has set an ambitious target for the shift in direction from nuclear and fossil fuels to renewable energy sources: reducing current energy consumption by 50% and…

Biological waste: biomass with huge potential

The efficient recycling of biowaste makes an enormous contribution to the bioeconomy and climate protection. Researchers in the Department of Waste Management and Emissions headed up by Prof. Dr.-Ing. Martin Kranert at the Institute for Sanitary Engineering, Water Quality and Solid Waste Management (ISWA) at the University of Stuttgart, are exploring the optimisation potential of biowaste recovery.

Plants as models for self-repairing materials

It’s a great idea: everyday products that can repair themselves. Although it’s still a pipedream, the foundations are already being laid in a series of investigations being carried out by Dr. Olga Speck from the University of Freiburg. Dr. Speck is a botanist who is studying wound-healing reactions in plants to try and find mechanisms that can be used as models for developing materials with “self-healing powers”.

Living plant construction: the vivification of architecture

Trees do not just provide timber, they can also be harnessed for construction without the need to cut them down. The term Baubotanik, Living Plant Construction in English, refers to combining modern materials with tree shaping. It shows how a new kind of architecture allows trees to continue growing when joined to temporary steel structures. It uses new design techniques, is climate friendly and of practical use.

Nanofur for cleaning up accidental oil spills in water

Accidental oil spills such as those following oil disasters need to be cleaned up as quickly as possible. Researchers from the KIT in Karlsruhe have now developed an environmentally friendly process that can eliminate oil spills effectively. Nanofur is a material that imitates the fine hairs of aquatic ferns and is capable of absorbing large amounts of oil within a relatively short time.

Natural genetic engineering

New plant breeding technologies, and the CRISPR/Cas technique in particular, are making headlines. For the first time in the history of agriculture, these technologies enable the quick and, in particular, precise modification of DNA at a predetermined locus. However, these methods provide authorities with an unexpected headache: are genome-edited plants genetically modified organisms or not?
