Ⅰ. Introduction
1. Background of research
o Chemical recycling such as pyrolysis is attracting attention as a means to deal with 1) the rapid increase in plastic waste due to the shift to the non-face-to-face lifestyle during the COVID-19 and an increase in delivery, and 2) large amounts of greenhouse gases emitted during the processes of production, consumption and disposal of petroleum-based plastics.
- Pyrolysis of waste plastics is a technology to obtain oil by chemically decomposing plastics in an oxygen-free atmosphere (about 600℃ or lower). It can treat waste plastics such as mixed vinyl that are difficult to mechanically recycle, secure petroleum substitutes, and reduce greenhouse gas emissions compared to incineration, simultaneously.
o Pyrolysis of waste plastics is regarded as a major means to reduce the source of waste plastics and achieve carbon neutrality by 2050.

- (2021.10) “2050 Carbon Neutrality Scenarios” and the “2030 NDC target”
- (2021.12) “K-Circular Economy Implementation Plan for Carbon Neutrality”
o The new government’s policy tasks include the ‘transition to pyrolysis’, and research is needed to timely suggest policy directions in terms of the circular economy to realize carbon neutrality.
