  • Microorganisms purify ground water

    Press release / 1.9.1998

    Pilot plant

    Chlorocarbons are often found as contamintations in ground water and soil. A new two-stage biological process uses microorganisms to degrade these hazardous compounds and purify the ground water.

  • Surfactants under control by Tensioline

    Press release / 1.6.1998

    Tensioline

    At the Fraunhofer IGB an apparatus has been developed for the automatic on-line controlling of surfactants concentration in industrial process and cleaning baths or in surface waters.

  • Bipolar memebrane

    Germany was the first country to enact a recycling (the so-called "closed loop economy") law in 1996: Instead of disposing waste it ensures the recycling or reprocessing of waste materials with the aim of saving natural resources. Fraunhofer IGB has developed a process for combined waste water purification and acid recycling. This not only protects the environment but also reduces costs.

  • Quality feed from sprouted seeds

    Press release / 2.3.1998

    Bioreactor

    Grain and sprouts have the potential to improve the quality of animal feedstuffs they contain all of the essential nutrients and minerals in a digestible form. A new germination procedure will enable sprouts to be produced on a large scale under controlled conditions.

  • Fixed-bed circulation reactor

    Fixed-bed reactors with immobilized biomass are applied increasingly in waste water purification. However, they have one disadvantage: Their flow channels block easily. Now, at Fraunhofer IGB a bioreactor has been developed, whose fixed-bed particles are circulated from time to time. This allows continuous, trouble-free operation.

  • More energy, less waste

    Press release / 15.9.1997

    A new method for disposing of organic waste offers some clear advantages: compostable materials and sewage sludge can be used as a source of energy. At the same time, the volume of waste is reduced by over 50%.

  • Hollow fiber

    Fraunhofer researchers have developed a component which regulates the humidity in air conditioning systems, removes carbon dioxide from the air, and purifies the water which condenses – it will even produce drinking water. And the device is hardly larger than a can of lemonade.

  • Stroma cells

    Exhaustive testing is required for cosmetics and medicines before they can be released on the market. An artificial cornea provides a valuable alternative to subjecting live rabbits to the Draize test.

  • How new blood vessels are formed

    Press release / 1.4.1997

    Angiotropin

    Tiny blood capillaries transport blood to almost every cell in the body. Fraunhofer scientists have now identified a factor that encourages the formation of new blood vessels. This opens up new perspectives in the treatment of circulatory disorders.
