폴리에스터 폐자원의 화학 원료화 기술
Feedstock Recycling Technology from Polyester Wastes

초록
PET는 자연 미생물에 의해서는 완전히 분해되지 않고, 산업의 발달과 소비 증가에 따른 PET의 광범위한 사용과 보급에 의한 많은 PET 폐기물의 발생은 심각한 환경문제를 야기한다. 이를 처리하기 위한 매립 및 소각은 소중한 화학자원의 경제적 손실이기도 하다. 이러한 환경 및 경제적 문제들을 다룰 수 있는 PET의 재활용 및 재 처리에 관한 다양한 방법들을 제시하였다. 그 중 폴리에스터 폐자원의 화학원료화가 매력적인 방법으로 각광받고 있다. 화학 원료화는 화학반응을 통해 고분자 PET 사슬을 분해시키고, 그 후 분리 정제과정을 통해 단량체와 같은 원료 화합물을 만드는 것이다. 이 원료 화합물로부터 새로운 폴리에스터를 재합성할 수 있기 때문에 폐 PET의 처리에 좋은 대안이라 할 수 있다.
Wide spread application and non-biodegradability of the poly(ethylene terephthalate) generate a huge amount of waste and disposal, posing serious environmental problems. Disposal of the PET wastes also can be thought as an economic loss of valuable chemical resources. We present various ways of feedstock recycling of PET waste to deal with environmental and economic problems. Feedstock recycling is one of promising technologies. It is based on the concept of depolymerizing the condensation polymer such as PET through solvolytic chain cleavage into low molecular products which can be purified and reused as raw materials for the production of high quality chemical products.
