Energy-efficient cascade use of biogenic waste taking into account new requirements for waste air treatment and compost quality

The aim of the EKaBio joint research project is to modify the process management of bioprocessing plants using cascade utilisation in such a way that maximum energy efficiency is achieved while at the same time complying with future exhaust air standards. To this end, process parameters of the treatment chain are to be systematically varied and the energy yield in the anaerobic process maximised.

The basis of our research work will be large-scale investigations, which we will carry out in a plant in the district of Aurich with original biowaste. Among other things, a biowaste treatment plant with cascade utilisation is located at the site. In order not to endanger its regular operation, the batch tests are also being carried out in the neighbouring mechanical-biological treatment plant for residual waste. The continuous rotting tests, which are decisive for energy consumption, are mainly carried out in the cascade plant.
