It's a win-win solution that has so far mostly failed because of the price: Cell-based meat could allow meat lovers to consume without moral, environmental, and climate concerns. There have been research projects on this since the 1970s, but commercialization has always failed due to production costs. Merck, the Darmstadt-based chemical and pharmaceutical company, now wants to change this and is seeking research cooperation with Darmstadt Technical University and Tufts University in the United States.

AMSilk is accelerating its growth: The world's first commercial supplier of high-tech biopolymers made from artificial silk has received further financing from its existing as well as additional investors. This means that the company, which is based in Martinsried near Munich, has access to an additional 29 million euros. The biotech specialist intends to use this money to "accelerate industrial scale-up and expand commercial operations to new markets."

Popcorn is a popular snack - but that's not all. The grains could also be a new resource for replacing conventional plastic or Styrofoam. A team led by Göttingen researcher Alireza Kharazipour has spent ten years taking a closer look at popcorn grains to find out whether they are suitable for the production of new sustainable products. As a result, a process has been developed with which 3D molded bodies for various packaging can be produced from a popcorn granulate.

Meat is not the problem, but the way it is produced - that is the credo of the German start-up Innocent Meat. The young company led by CEO Laura Gertenbach and CTO Patrick Nonnenmacher wants to drive the transformation from traditional livestock farming to a sustainable and efficient model via cell culture-based meat.

Outdoor textiles must be practical and functional: they should protect equally well against rain, wind and dirt. To meet these high demands, the textile industry has so far used so-called hydrophobing agents for impregnation. However, these usually consist of petroleum-based fluorine compounds, which have been proven to harm the environment and people. Rudolf GmbH, a company specializing in textile chemicals, now wants to launch a fluorine-free alternative made from renewable raw materials.

Hemp is one of the oldest crops in the world. Various parts and species of the plant are used to produce textile fibers, building materials, medicinal products, but also foodstuffs. The food industry relies primarily on the healthy ingredients of the hemp plant, which are rich in proteins, carbohydrates and fats, but also vitamins and minerals. Industrial hemp, on the other hand, is cultivated specifically for industrial use.
