Goldmine “biomass” – carbonauts convert biomass into high-value platform products

Biomass can be carbonised and converted into certified carbon using a technology called “carbotwin”, which enables simultaneous production of energy. The carbon is thus stored in the end products and does not enter the atmosphere as CO2. Carbonauten, a start-up company from the Baden-Württemberg town of Giengen, shows that the process is not only environmentally friendly, but also economically viable.

Over the next four years the European UNRAVEL project will demonstrate a sustainable and economically feasible biorefinery for the conversion of second generation biomass into fuels, chemicals and building materials. In their efforts the partnership from six European countries are supported by the Bio Based Industries Joint Undertaking (BBI JU) which funds the UNRAVEL project with 3.6 million Euros.

Power-to-X technologies and renewables

Storage solutions will be very much in demand as renewables account for a growing share of electricity in the grid. One option – converting fluctuating green electricity into chemical energy carriers or raw materials – looks particularly promising. Scientists at the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) want to put power-to-X processes into action with a two-pronged strategy.

Using ultrapure lignin from the lignocellulosic biorefinery at the Fraunhofer Center for Chemical-Biotechnological Processes CBP in Leuna, researchers at the Technical University of Hamburg-Harburg (TU HH) have produced lignin-containing aerogels and processed high-porosity insulating boards with excellent insulation properties. The lignin was recovered from beech residual wood at the Fraunhofer CBP using the Organosolv process.

LIGNOSIT - using lignin in value-added products

The environmental footprint of petroleum-based plastic products does not look good. Alternatives for plastic production involving renewable raw materials are now being sought. Wood is experiencing a renaissance. Prof. Dr. Marie-Pierre Laborie, who holds the Chair of Forest Biomaterials at the University of Freiburg, and her team are researching the potential use of lignin, the natural glue in wood.

Back to the future? From wood to coal to a sustainable bioeconomy

The historic transition from wood to hard coal was successfully made in the 19th century. We are now on our way to a sustainable bioeconomy. Research carried out by the Faculty of the Environment and Natural Resources at the University of Freiburg reveals what history can teach us about the transition to a more sustainable, biobased economy.

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…

From biomass to diesel

Using the power of microbes: biochemists from Leipzig and Tübingen use the combined power of microbes and electrolysis to produce fuels from organic material. This new process uses electricity from renewable resources to produce diesel from organic waste and green cuttings, amongst other things, and can therefore also be used for storing wind and solar energy.

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.

The bioeconomy – buzzword or future concept?

The use of wood and other renewable raw materials for the production of industrial goods presents opportunities and risks. Is the shift from petroleum to wood possible and how can such a shift be best achieved? A research project at the University of Freiburg combines forestry know-how with political science methodology in order to sound out the bioeconomy.

Indicators that enable more effective biomass utilisation in Baden-Württemberg

Action plans prove all the more resilient for being well supported by facts and figures and based on thorough ethical thinking. This equally applies to the utilisation of biomass. Researchers involved in an interdisciplinary research project at the Universities of Stuttgart and Tübingen have therefore developed indicators to help improve the utilisation of biomass in the future. The findings are based on investigations of the utilisation pathways…

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…
