Methodology

We base our research on a combination of laboratory and pilot-scale experiments, mass and energy balances, process modeling, and advanced analytics. We utilize pyrolysis, catalytic pyrolysis including cracking and dry reforming, combustion tests in a rotary kiln, anaerobic digestion, membrane separation, and catalytic hydrogenation in our research on waste management and its further utilization.

  • Consulting services in the field of thermochemical processes and chemical technologies.
  • Mass and energy balances of industrial processes and process optimization in industrial practice.
  • Determination of thermal-technical parameters necessary for evaluating the fuel and energy potential of various materials.
  • Determination of the chemical composition not only of fuels and waste materials (waste plastics, waste biomass), but also of products associated with the investigated processes in the chemical and petrochemical industry (process and pyrolysis gases, synthesis gas, organic liquids and tars, deposits from equipment, etc.).
  • Comprehensive characterization of carbonaceous materials from pyrolysis and gasification processes, including the assessment of their ecotoxicity (in cooperation with the Water Treatment and Analysis research group).
  • Research focused on increasing the efficiency of anaerobic methane production in both wet and dry processing methods and on the optimization of the mass and energy balances of industrial processes. This includes a detailed analysis of biomass, biodegradable waste, and biogas, which allows for precise characterization and evaluation of the efficiency of individual processes.
  • Consulting on the optimization of feedstock pretreatment and the modeling of process conditions (e.g., loading, retention time, mixing intensity) for anaerobic digestion. Evaluation of the effect of adding additives (e.g., trace elements, buffers, enzymes, or microorganisms) on the course of anaerobic or aerobic processes.
  • Evaluation of aerobic biomass degradation processes in the form of composting, at both the experimental and pilot-scale levels.

Results and Applications

The group's research supports the safe and efficient use of waste as a source of energy, chemical raw materials, and materials. The results find application in the chemical recycling of plastics, energy recovery from waste, reduction of emissions from combustion processes, production of synthesis gas, biochar, and carbonaceous materials, optimization of biogas technologies, and material utilization of solid residues. They thus contribute to the more efficient use of secondary raw materials and the development of the circular economy.
