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.

Burger

Containing protein, vitamins and minerals

The world population is growing and resources are becoming scarce. An important contribution to food security could be breeding insects instead of cattle, pigs and poultry. Insects are rich in protein, vitamins, minerals and unsaturated fatty acids. Insects also consume significantly less resources than their four-legged counterparts.

Engine cover

Castor oil protects the engine

Components in the engine compartment of a car must be able to withstand extreme heat loads of over 200 degrees Celsius. Daimler uses biopolyamide engine covers for the Mercedes A-Class. While conventional plastic is produced from crude oil, the cover consists largely of castor oil. The oil is extracted from the seeds of the castor oil plant Ricinus communis, which belongs to the spurge family.
