On 1st May, 2020 the joint research project EKaBio - Energy-efficient cascade use of biogenic waste under consideration of new requirements for exhaust air treatment and compost quality started.
The aim of the EKaBio project is to modify the process control of bio-waste treatment plants with cascade utilisation in such a way that maximum energy efficiency is achieved while complying with future standards for exhaust air treatment. This goal is to be achieved by systematically varying process parameters of the treatment chain while maximising energy yield in the anaerobic process. The basis will be large-scale technical investigations at a plant in the district of Aurich. The site includes a bio-waste treatment plant with cascade utilisation and a mechanical-biological waste treatment plant for residual waste. In order not to endanger the regular operation of the bio-waste treatment plant, the batch tests are first carried out in the neighbouring mechanical-biological treatment plant. Subsequently, the continuous composting tests, which are decisive for the energy consumption, take place in the cascade plant.
The RWTH Aachen University represented by the Department of Processing and Recycling (I.A.R.) coordinates the joint project. Further project partners are, the University of Stuttgart, represented by the Institute for Sanitary Engineering, Waterquality and Solid Waste Management (ISWA), STRABAG Umwelttechnik GmbH, MKW - Materialkreislauf- und Kompostwirtschaft GmbH & Co. KG and PlasmaAir AG. The project is scheduled to run for three years.
The German Federal Ministry of Economics and Energy (BMWi) fund the project under the program Energy-saving industrial processes - material efficiency, disposal and recycling technology under the funding code 03EN2033A-F. The promoter is Forschungszentrum Jülich GmbH. The authors are responsible for the content of the publication.
