Drinking straw
Into the stomach instead of the garbage
Every year, billions of plastic tubes end up in the garbage. But there is an alternative: the Eatapple straw consists of specially treated apple residue. In the initial phase of the company, the drinking straw was produced with the help of a converted pasta machine at the Karlsruhe Institute of Technology. Production now takes place at the German Institute of Food Technology - where it is possible to produce between 10,000 and 100,000 drinking straws per day.
Deruster
Counteracting rust
The brown coating is formed when iron oxidizes. Rust is not only unattractive, it also causes damage because it continues to decompose the metal. Conventional rust solvents contain acids as an effective component, usually phosphoric or hydrochloric acid. These reverse the process and stop the formation of rust. Acids, however, are dangerous to handle and pollute the environment.
Understanding and protecting the groundwater ecosystem
We drink from it, water the fields with it, or use it as a coolant or solvent: groundwater. This vast reservoir of water under our feet is essential for human and animal life, but for the majority of the time we take it entirely for granted. For groundwater ecologist Christian Griebler, this invisible water is far more than just a commodity. “The groundwater is so clean only because of the biology that it contains, which ultimately has a purifying function.
T-Shirt
Ecological and sustainable
The start-up wijld uses wood as an alternative to polyester fibres, but also to cotton. If one compares the manufacturing process of a conventional cotton T-shirt with a wooden shirt, 1000 litres of water and more than 600 g CO2 are saved by using the wooden yarn. The wooden shirt is also very comfortable to wear. It is surprisingly soft and pleasant on the skin, also breathable, tearproof and antibacterial.
Decking boards
Non-slip and splinter-free
Blader of grass consists of about 50 percent cellulose, a highly resilient material. The cellulose from the blades of grass is broken down in a biorefinery. For this purpose, the blades of grass are washed in a warm water bath. The grass is cleaned of dirt and stones and the heat also loosens sugar, proteins and amino acids from the stalks. After drying, the blades of grass are fused with recycled plastic.
Farming in the digital age
The profession of farming has a long tradition in Robert Hagemann’s family. Without the German reunification, however, it is unlikely that the native of Lower Saxony would have followed in the footsteps of his grandfather and father. In 1990, the family of the then 15-year-old Robert Hagemann moved to the region of Prignitz, where they established an agricultural business in Groß Pankow, far from his old home. “My father had always dreamed of having his own large company.
Running shoes
Ideal properties
As synthetic materials are much easier to care for than leather and also resistant to moisture, they are increasingly being used as uppers for running shoes. adidas uses a very special material in its new "Futurecraft Biofabric Shoe". The upper of the shoe is made entirely of artificial spider silk. Spider silk is extremely robust. The threads are thinner than a hair, yet more tear-resistant than steel, more elastic than rubber and also ultra-light.
Diapers
An average of 6000 diapers per child
Although every full diaper contains valuable nutrients, they are currently incinerated with household waste in huge quantities. Each child goes through about 6000 diapers before it is completely toilet trained at the age of about two and a half years. The most important elements of a conventional diaper are made of petroleum-based materials. These are outer shell of the diaper as well as the superabsorber (SAP), which absorbs and stores the liquid released.
