Thermal energy accumulation by hydrolysis treatment of the heavy fraction of waste plastics containing PVC by dehydrochlorination for its material and energy recovery

Provider: Technologická agentura České republiky
Programme: THÉTA 2 - 2. veřejná soutěž
Implementation period: 01.07.25 - 31.12.28
Workplace: Fakulta chemicko-technologická - Oddělení chemického inženýrství
Investigator: Weidlich Tomáš
Team member: Kašparová Jana | Svobodová Markéta | Jašúrek Bohumil | Hidalgo Herrador José Miguel
Description:
The main result of the project is the research of a technology for the use and accumulation of waste low-potential heat to dehydrochlorinate waste PVC unsuitable for recycling. The output of the proposed technology is a valuable material unsaturated dechlorinated polymer that can be used for further raw material, material or energy recovery. This will lead to a reduction in landfilling of PVC, which is completely unsuitable for energy purposes due to the high concentration of bound chlorine, and thus improve environmental sustainability. A by-product of the technology is a harmless brine (for hydroxide production based on circular economy principles).
