Biorefinery: new paths to build our tomorrow

Sustainability is in vogue. And it’s not a question of wanting to be sustainable, but having to be: as the latest report from the Intergovernmental Panel on Climate Change shows, protecting the climate and the environment calls for swift action. Biorefineries that use renewable raw materials and recycle industrial raw materials are playing an important role in the bioeconomy concepts of many countries - including the state of Baden-Württemberg.

The HUEHOCO GROUP Holding GmbH & Co. KG, a family-owned company from Wuppertal, North Rhine-Westphalia, has acquired a 5 percent stake in carbonauten GmbH.

His new project is aimed at using the CRISPR/Cas method to freely combine genes in crops, thus making Gregor Mendel’s dream come true.

Rising sea levels due to climate change and artificial irrigation cause soil salinity to increase. This has a negative impact on agriculture, including viticulture. The plants die, yields decrease. Researchers of Karlsruhe Institute of Technology (KIT) have therefore studied a wild grapevine of higher salt tolerance. Their goal is to identify the genetic factors that make the grapevine resilient.

Phosphorus recovery from sewage sludge - 21/10/2020

Bacteria help to recycle phosphorus

Biotechnology for the bioeconomy: in something known as the P-bac process, sulphur bacteria extract phosphorus from sewage sludge ash. Phosphorus is one of the key building blocks of life and an essential nutrient for plant growth. When there is not enough phosphorus in the soil, farmers apply it via organic or mineral fertilisers.

Textiles can be coated with the biopolymer chitosan and thus made water-repellent by binding hydrophobic molecules. The good thing is that this can also replace toxic and petroleum-based substances that are currently used for textile finishing. In the last few years Fraunhofer IGB and partners have developed technology to provide fibers with the desired properties using biotechnological processes and chitosan.

Bacteria produce bioplastics: resource-saving and very environmentally friendly

Using living cells as mini-factories to produce plastic from nothing more than water, sunlight and carbon dioxide; plastic that is also 100 percent degradable – it sounds far-fetched but it actually works: researchers at the University of Tübingen have genetically engineered cyanobacteria so that they fill their cells to the brim with polyhydroxybutyrate. The researchers are now turning the idea into reality with the development of pilot plants.

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.
