Research on product characterization of waste plastic pyrolysis plant process

Globally, the concentration of greenhouse gases in the atmosphere is increasing due to the rapid development of industry and COVID—19. In response, developed countries have established greenhouse gas reduction targets and basic plans as a long—term strategy for carbon neutrality, and South Korea has also promoted various policies. In particular, the Ministry of Environment of South Korea has expanded the recycling subsidy unit price and subsidy allocation ratio to focus on plastic materials and chemical recycling to expand high-value recycling, and has reorganized facility classification and prepared recycling standards by shifting from landfill and incineration to pyrolysis. Currently, most pyrolysis technologies in South Korea are batch-type facilities, and operating conditions and post-treatment processes vary by company. Therefore, this study aims to identify the characteristics of waste inputs to existing pyrolysis facilities and the characteristics of products according to the post—treatment process.
