Waste-to-energy

Waste-to-energy is a key technology for the treatment of municipal solid waste and unavoidable waste that cannot be recycled. The energy recovery process produces solid residues, namely fly ash and bottom ash, which can be used as secondary raw materials. Our research efforts focus on the following aspects:

• Processing and material recovery of fly and bottom ash: We are developing methods to process and recover these solid residues. In the case of fly ash, we focus on the removal of hazardous properties and the possibility of extracting salts and metals. In the case of bottom ash, we are developing efficient processes to recover valuable components, especially non-ferrous metals, and exploring the possibilities for its use in the construction industry;
• Utilization of process wastewater: We are investigating the possibility of utilizing process wastewater, for example in the production of gypsum. In this way, we contribute to the efficient use of residues from waste-to-energy technologies and minimize the negative impact on the environment.
