In 1998, Tecnaro GmbH was set up in Pfinztal as a spin-off from the Frauenhofer Institute for Chemical Technology (ICT) with the aim of bringing a new kind of medium to market. Since its foundation, it has been developing, producing and selling premium thermoplastic materials made from liquid wood. Together with Helmut Nägele, Jürgen Pfitzer has been managing the company in Ilsfeld-Auenstein, Baden-Württemberg, since 1998.

Nappies of renewable raw materials that are completely biodegradable: That is the aim that Dominik Franck is pursuing with his 'Fairwindel' company. 'Inspired' by his daughter's mountain of nappies, the chemist has developed a new type of nappy partly consisting of potato starch and maize. The 'Fairwindel' company, managed by Franck together with his wife in Mühlenbeck near Berlin, was commended in 2015 as a sustainability startup.

Insects as food present many advantages. That is something that Max Krämer, founder of Bugfoundation, is convinced about. What the geographer once encountered and learned to appreciate on his trips to Asia will soon be winning converts here. The young entrepreneur from Osnabrück plans to make European fast food healthier and more sustainable by means of the first 'insect burger'.

Simply dispose of cups, toys or shoes by throwing them onto the compost heap: That is what Thorsten Perl had in mind when developing his new 3D printer material. Together with his business partner Brian Cotty and their BioInspirations start-up based in the German city Eberswalde, the inventor of this sustainable printing filament is gaining enthusiasts for 'WillowFlex', and not just amongst 3D printer fans.

Researchers first presented the CRISPR-Cas genomic scissors in 2012 in the journal Science. In the meantime, the molecular precision tool has revolutionised the field of molecular biology. Holger Puchta from the KIT is one of the first researchers to use these genomic scissors to make targeted modifications to the genetic material of plants. In the interview, he explains how so-called genome editing works, and why the agricultural crops that result from this technology are indistinguishable from natural plants.

A visit to the toy fair in Nuremberg with all of its disposable plastic toys inspired the CEO of wijld GmbH Timo Beelow to create sustainable alternatives to these disposable products. The Wuppertal-based start-up successfully managed to create t-shirts that are made of the renewable resource wood (“WoodShirts”) and that are easily recyclable.

On their quest for ways to save water during farming, researchers are focussing more and more on sewage treatment plants. Within the cooperation project “HypoWave” Frankfurt-based researchers headed by the agricultural expert Martina Winker aim to develop a new method in order to use municipal sewage water more effectively for farming plants. Therefore, they are focussing on hydroponics.

Although peptides are already often used in cosmetics or the pharmaceutical industry, their unused potential is even greater. Their expensive and complex production however, has limited their application possibilities thus far. The Düsseldorf start up Numaferm has developed a new tool to remedy the situation. CEO Philipp Bürling is convinced the new Numaferm technology that was developed by his business partner Christian Schwarz will significantly reduce the production costs of peptides.

Plant diseases and pests are a plague for farmers and hobby gardeners all around the world. With her ‘Plantix’ app, Simone Strey from Hanover-based start-up PEAT is now offering a novel form of support for self-help. From the photos provided by users, the software not only identifies pest infestation and nutrient deficiency in plants, but also provides advice on how to deal with disease or parasites. The geobotanist Strey and her team were honoured with the ‘Innovation Award 2017’ at this year's CeBit, the world’s biggest digital fair.
