Waste Technology
All model systems for waste management in modern industrialised countries are dominated by the two aspects of management of material flow and closed-loop recycling.
The implementation of such systems requires the introduction of technologies that contribute towards the material- and energy-efficient production of goods. Once products have reached the end of their useful life, waste processing plants that provide for optimal waste reclamation are required to ensure that the waste material be recycled or used for energy recovery. For example, biogas obtained from organic waste, processed under anaerobic conditions, can be used to make industrial plants and even residential estates self-sufficient in energy.

Negative skin friction due to settlement of domestic waste was recognized to be the cause of damages of shafts in a landfill. The usual methods of statical calculation turned out to be improper within landfills. A settlement compensating gravel haunched shaft-structure based on the telescope principle was developed. The working order of the system was demonstrated until a landfill height of approximate 70 m. The telescopic effect worked as planned. The radial deformation and soilpressure overpassed the previsions without endangering the stability. Measures to be taken in order to reduce the negative skin friction are proposed (further information in German). Expand

During the vulcanisation of india-rubber to make high-quality rubber products, various filler materials, cross-linking agents and auxiliary materials are used. For the first time, a new measuring process based upon the relationship between the degree of mixing and electrical conductivity allows the purposeful control and regulation of the mixing process, thereby resulting in a substantial reduction in the number of defective batches. Further information is set out in the German language brochure.
