Weeds are a problem for many farms. In conventional farming, heavy equipment and pesticides are used to try to kill the unwanted plants or keep them in check. In organic farming, no chemicals are used. Here, the weed problem is solved mechanically or thermally. But even this method is not ideal: it is often expensive and can also disturb soil organisms and promote erosion. Researchers at the University of Rostock have now taken a closer look at weed vegetation in Mecklenburg-Vorpommern (MV) in a large-scale field trial. Eleven organic farms from MV were involved.

Fruit pits from plums, cherries, peaches or apricots usually end up in the trash. In fruit processing, over 500 million kilos of pits are thrown away every year in Europe alone. For Austrian start-up Kern Tec GmbH, this is a source of raw materials for new foods. The potential of this upcycling idea has also convinced the system service provider BayWa. Through its investment arm, BayWa Venture GmbH, the Munich-based company is now joining the food tech start-up as a partner and investor.

Building a bridge to the future - the project participants in the EU research project "Smart Circular Bridge" have taken this literally. To address the sustainability deficit of many established building materials, the experts have developed a walkway and bike path bridge made of a biocomposite material. The University of Stuttgart is also involved in this project.

Microalgae can produce many valuable substances, from dyes to omega-3 fatty acids or proteins, and are therefore a source of hope for the bioeconomy. They are not only used by manufacturers of food, animal feed and cosmetics. Microalgae are also becoming increasingly important for the production of biofuel and new plastics. The cultivation of these aquatic plants could also open up new business areas in agriculture.

Overfishing of the oceans is a global problem. According to the environmental protection organization WWF, 33% of commercial fish stocks are affected. In Europe, the situation is even more dramatic: In the Mediterranean and Black Seas, as much as 62.2% of stocks are considered overfished. Meanwhile, however, demand for fish continues to rise. Food tech startup Bluu Seafood wants to rebalance overfished seas with alternatives made from cultured fish cells.

Fluorine is a small atom with a big effect: For decades, the pharmaceutical industry has been using it to improve active medical ingredients. For example, fluorine can improve the binding of an active ingredient to its target molecule, increase the availability of the active ingredient to the body, or change the residence time of the active ingredient in the body. Until now, incorporating fluorine usually required complex chemical syntheses.

Almost every third startup founded in Germany in 2021 can be considered "green". This is the conclusion of the 4th Green Startup Monitor from the Startup Association and the Borderstep Institute. At 29%, the share of all startups is thus roughly at the previous year's level of 30%.

Medicine has always relied on the healing powers of nature. Plant-based active ingredients are therefore a sought-after raw material for both the pharmaceutical and cosmetics industries. However, their extraction from medicinal plants such as thyme and chamomile is subject to natural fluctuations, so that the active ingredient content varies. In addition, climate change and barren soils further reduce the concentrations of the ingredients, thus lowering the quality of conventionally extracted essential oil.

Flying powered by food scraps - that's how you could describe the vision of a team of researchers from the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS). Together with several partner institutions, the experts have developed a plant that can produce synthetic fuels and biogenic waxes from biogas. The raw material for this is biological waste.
