InBiRa: Insect biorefinery turns food leftovers into new products

Insect larvae can convert food leftovers and waste into secondary raw materials for technical products and cosmetics. Researchers are looking to establish an insect biorefinery for this purpose at the Fraunhofer IGB in Stuttgart. The InBiRa project is financed with a total of 3.8 million euros in EU and Baden-Württemberg state funding.

Pharmaceutical products, medicine, proteins, and nutrients are usually produced on an industrial scale in a bioreactor. Although the technology is well established, more research is needed in order to be able to increase the production volumes. A visual inspection of the production is usually not possible because bioreactors are made of opaque steel.

Valuable materials of all kinds - produced automatically in living cells

In future, algae could be used to produce practically everything that still requires petroleum, including plastics, fuels, medicines and food. Algae are also climate savers par excellence, because they bind ten times more CO2 than terrestrial plants. Festo, a company based in Esslingen, Germany, has developed a high-tech bioreactor that can be used to automatically cultivate the small green biofactories - and that do so a hundred times more…

Carbon dioxide is one of the main drivers of climate change – which means that we need to reduce CO2 emissions in the future. Fraunhofer researchers are highlighting a possible way to lower these emissions: They use the greenhouse gas as a raw material, for instance to produce plastics. To do this, they first produce methanol and formic acid from CO2, which they convert via microorganisms into building blocks for polymers and the like.

Electronic devices are still made of lifeless materials. One day, however, “microbial cyborgs” might be used in fuel cells, biosensors, or bioreactors. Scientists of Karlsruhe Institute of Technology (KIT) have created the necessary prerequisite by developing a programmable, biohybrid system consisting of a nanocomposite and the Shewanella oneidensis bacterium that produces electrons.

For hundreds of millions of years plants have had the ability to harness carbon dioxide from the air using solar energy. The Max Planck research network MaxSynBio is on the trail of building artificial cells as sustainable green bioreactors. The research team led by Tobias Erb from the Institute for Terrestrial Microbiology in Marburg has now succeeded in developing a platform for the automated construction of cell-sized photosynthesis modules.

A vision: insect biorefineries as components of a sustainable bioeconomy

Eco-friendly and responsibly manufactured products are more in demand than ever before. Specific research is being carried out into materials and applications for a wide variety of uses. The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB is working with Hermetia Baruth GmbH on the vision of an insect biofactory that uses waste materials to produce a wide range of products such as biosurfactants, animal feed or foils.

A transparent and thermally stable polyamide – 100 percent biobased

The natural substance 3-carene is a component of turpentine oil, a waste stream of the production of cellulose from wood. Up to now, this by-product has been incinerated for the most part. Fraunhofer researchers are using new catalytic processes to convert 3-carene into building blocks for biobased plastics. The new polyamides are not only transparent, but also have a high thermal stability.

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.

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.

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.

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.

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.

IneraTec: greenhouse gases for the production of synthetic fuels

The founders of the company IneraTec are developing a chemical reactor that can produce synthetic fuels from a broad range of different gas sources. What is completely new is the size of the reactor: it is no bigger than a desk. The IneraTec founders have found a way to design a compact reactor that fits into a container and only needs be connected to a gas source. At present, the reactor is set up to use methane as a source gas, but it has the…
