Energy-efficient exhaust air treatment in mechanical-biological waste treatment plants
The “Energy-efficient exhaust air treatment (EnAB)” project, funded by the BMWi as part of the German government’s 6th Energy Research Program, was carried out in cooperation with RWTH Aachen University, the University of Stuttgart and the company MKW (Großefehn).
The aim of the project was to increase the energy efficiency of MBT by using alternative and innovative exhaust air treatment methods.
In EnAB, four project partners researched measures aimed at increasing energy efficiency and process efficiency in MBT plants. The objectives of EnAB were to be achieved on the one hand by using alternative exhaust air treatment plants and on the other hand by modifying the operating modes in the mechanical (MA) and biological (BA) treatment stages. In the project, large-scale test series were carried out in an existing MBT plant with an annual treatment capacity of approx. 60,000 Mg. In addition, partial exhaust air flows from the BA were treated in a pilot plant with a modified exhaust air management system.

Process combination for the treatment of exhaust air flows
The BMWi-funded ZIM project “Functionalized mineral composites as a dielectric barrier in the process combination of dielectrically impeded gas discharge, mineral adsorber and bioscrubber for the treatment of exhaust air streams (MiCoPlAST)” was carried out in cooperation with the University of Stuttgart, RWTH Aachen University and Richter Akustik & Design (Melle).
The aim of this research project was the production of functionalized composite panels as a dielectric barrier for a non-thermal plasma discharge (NTP) for the treatment of exhaust air streams containing VOCs.
Various parameters were investigated during development, such as a hydrophobic material property. Moisture in the exhaust air has emerged as a significant problem in previous projects and has led to discontinuous operation. This was to be prevented and remedied using new materials and surface treatments. Further options such as doping with catalytically effective materials should enable an increase in efficiency.

Thermal plasma systems for the treatment of odor-intensive exhaust air flows containing methane and VOCs
The research project “Treatment of odorous, methane- and VOC-containing exhaust air streams by a process combination of non-thermal plasma, mineral adsorber and scrubber stage – A combined Plasma-Adsorber-Scrubber System or Treatment of intensively smelling Crude gases (PlASTiC)”, funded by the BMBF as part of the KMU-innovativ: Ressourcen- und Energieeffizienz Schwerpunkt “Energieeffizienz / Klimaschutz” funding program, was carried out in cooperation with the University of Stuttgart and the companies DURTEC GmbH and Liutec – Labor für innovative Umwelttechnik.
The aim of this project was to develop and optimize a modular exhaust air purification process for the simultaneous reduction of emissions of VOCs (including methane), odorous substances and gaseous inorganic pollutants, such as those encountered in animal husbandry, sewage sludge drying or waste composting.

Development of a fine dust separator for wood firing systems
The DBU-funded research project “Development of an electrostatic precipitator for small-scale biomass combustion plants – 1st phase” was carried out in cooperation with the IFK at the University of Stuttgart.
The aim of the project was to develop a compact and reliable electrostatic precipitator for small biomass combustion plants.
The prototype of an electrostatic precipitator resulting from this project was the basis for the subsequent funding project “Investigation of the relationship between separation efficiency and particle properties in electrostatic precipitators for small biomass furnaces”.

Further development of a fine dust separator for wood firing systems
The DBU-funded research project “Investigations into the relationship between separation performance and particle properties in electrostatic precipitators for small biomass furnaces” was carried out in cooperation with the IFK at the University of Stuttgart. Extensive measurements were carried out with the prototype of the electro fine dust separator (EFA) on the test stand at the IFK.

KG (Großefehn), pbo Ingenieursgesellschaft mbH (Aachen) and STRABAG Umwelttechnik GmbH (Düsseldorf) and is a follow-up project to the previous EnAB and EnAB2 research projects.
In the joint project EKaBio, large-scale tests were carried out to optimize the operation of cascade plants with regard to material flow management, emission reduction and energy efficiency increase.
The exhaust air analyses have shown that the limit values of the TA-Luft are complied with. It was also shown that methane in particular was a major component of the total carbon content (TOC). In contrast to other C components, methane cannot be broken down in the biofilter. In addition, methane cannot be effectively removed from the exhaust air stream under economically justifiable conditions with the current state of the art.
