Ⅰ. Introduction
1. Background of the Study
o To transition toward a circular economy, enhancing resource efficiency and circularity is crucial. Recycled materials play a key role in reducing the consumption of natural resources and establishing a circular loop by connecting upstream and downstream industries.
ㅇ While past policies on resource circulation have focused on the post-management of waste that was already generated, future policies should emphasize reducing resource consumption from the product design stage and increasing material circularity to strengthen more sustainable product policies.
ㅇ To achieve this, it is necessary to monitor and manage the environmental impact throughout the product lifecycle. Particularly, efforts are required to evaluate the sustainability of suppliers across industry supply chains and to secure low-carbon materials and recycled materials.

o It is projected that the market for recycled materials will expand as a means to address issues such as global climate crisis response and carbon neutrality.
ㅇ An analysis suggests that increasing the proportion of recycled and bio-based plastics to 30% within the EU by 2030 could reduce CO2 emissions by 37 million tons and cut fossil fuel-based plastic production by 13 million tons.

o Major countries including the EU, the US, and Japan are promoting the use of recycled materials to achieve goals of carbon neutrality and the establishment of a circular economy.
ㅇ Recently, discussions are underway to recognize pyrolysis-produced recycled oil (used as recycled naphtha to substitute petroleum-base
