초록

최근 탄소 중립 이슈와 함께 가장 많은 조명을 받고 있는 환경 문제로는 폐플라스틱 처리 문제가 있다. 폐플라스틱의 재활용 기술 중에서도 고온의 조건에서 유기물을 전환하여 원료 및 에너지로 재활용하는 열화학적 재활용 기술은 그동안 폐플라스틱에 주로 이용되어 왔던 물질재활용의 한계를 넘어선 기술로 평가 받고 있다. 열화학적 재활용 기술은 폐플라스틱을 원래 플라스틱의 원료로 재순환할 수 있는 순환경제의 핵심 기술로 부각되고 있으며 후속공정 및 최종 생산품의 활용 방법에 따라서 원료(Chemical recycling) 및 에너지(Waste to energy)로 재활용이 가능한 장점을 가지고 국내 뿐 아니라 세계적으로 주목을 받고 있다. 본 논문에서는 열화학적 재활용의 대표적인 세가지 기술인 연소, 가스화, 열분해에 대하여 살펴보고 최근 주요 기술 동향을 제시하고자 한다.

One of the foremost environmental challenges, alongside the contemporary focus on achieving carbon neutrality, pertains to the pervasive issue of plastic waste. Thermochemical recycling technology, operating under high-temperature conditions to covert organic matter and recycle it into raw materials and energy, represents a transformative approach surpassing the conventional bounds of material recycling predominantly applied in plastic waste management. The thermochemical recycling paradigm is emerging as a pivotal technology within the circular economy, capable of transforming waste plastics into raw materials for producing original plastics. Its significance extends beyond national borders, garnering global attention due to its versatility as a chemical or energy recycling method, contingent upon the subsequent processes and final products. This study aims to scrutinize three quintessential thermochemical recycling technologies: combustion, gasification, and pyrolysis. Furthermore, the study discusses the recent major technology trends of these technologies.
