Grey biotechnology - characterisation and modelling of environmentally relevant processes


Grey biotechnology or environmental biotechnology deals primarily with waste water, waste and exhaust air problems. The most varied of analytical and modelling methods are employed for this purpose. Risk assessments of target objects can be carried out using experimentally generated data combined with mathematical models.

One such project carried out here at the Institute tests the gas generation rate of waste previously processed using mechanical and biological methods. In this project, information on complex biological and chemical processes within a landfill body is obtained on a laboratory scale using various sizes of reactor.

Another project supported by International Research Training Group 802 focuses on the testing of contaminated ground water in the Braunschweig area. Conclusions regarding the degradation potential of harmless substances in the soil should be drawn on the basis of field measurements.
  • Investigation of waste previously processed using mechanical-biological techniques on a laboratory scale
  • Simulation of the gas formation in landfill waste using artificial neuronal networks
  • Investigation and modelling of a contaminated aquifer on a field scale
  • Validation and evaluation of ground water model uncertainty within the scope of a risk assessment
