Plastic pyrolysis has attracted considerable attention as a reliable and emerging technology for resource recycling as it can generate valuable by-products in the process.

A recent study reports that using a decentralized plastic pyrolysis model, combined with seasonal heating demand, profits can be increased, and the process is not likely to suffer a loss when compared to the conventional heating process. concentration program. This breakthrough was led by Professor Hankwon Lim in the School of Energy and Chemical Engineering at UNIST.

In this work, the team demonstrated for the first time a proof of concept, pilot-scale cogeneration system for biomass heating and plastic-derived pyrolysis oil production. The team further evaluated a disruptive technological-economic business model for decentralized plastic pyrolysis. They then compared it to a traditional centralized industrial system through top-tier supply chain optimization.

Their findings suggest that using a plastic In the pyrolysis model, combined with the seasonal heating demand, profits can increase and the process is not likely to lose while the centralized process can suffer. Furthermore, compared with concentrated pyrolysis, transportation costsand related CO2 emissions significantly reduced by 3–10 x and 1.4–7 x, respectively, according to the team.

Their findings were published in the August 2022 issue of Cleaner Production Magazine. This study was carried out in cooperation with researchers from Lahore University of Management Sciences in Pakistan.
