초록

1990년대에 들어서면서 폐플라스틱을 화학적으로 재활용하여 환경문제나 경제적 문제를 해결해보려는 노력이 증대되었고, 이 추세에 따라 폐 PET를 화학적으로 재활용하여 원료화하려는 시도가 활발해졌다. 본 연구에서는 PET 폐자원의 화학원료화 및 고부가 활용기술에 대한 특허와 논문을 분석하였다. 분석범위는 1974년에서 2013년까지의 미국, 유럽연합, 일본, 한국의 등록/공개된 특허와 SCI 논문으로 제한하였다. 특허와 논문은 키워드를 사용하여 수집하였으며, 기술의 정의에 의해 필터링 하였다. 특허와 논문의 동향은 연도, 국가, 기업, 기술 등에 따라 분석하여 고찰하였다.

Since 1990s, efforts to recycle the waste plastics by chemical methods have increased. And in accordance with this trend, attempts have become active to use the waste PET as raw materials of chemical industries. In this article, the patents and papers for development of commercial technology for feedstock recycling and high end products from PET wastes were collected and analyzed. The open patents of USA (US), European Union (EP), Japan (JP), and Korea (KR) and SCI journals from 1974 to 2013 were investigated. The patents and papers were collected using key-words and filtered by the definition of the technology. The patents and papers were analyzed by the years, countries, companies, and technologies and the technical trends were discussed in this paper.
