Abstract

납으로 오염된 오물과 건전지 케이싱은 유리화된 슬래그와 연소가능한 가스를 형성하기 위해서 이들을 열분해시키는 플라즈마 아아크로를 사용하여 교정된다. 휘발된 납(다른 중금속들)과 함께 연소가능한 가스가 종래의 정련로로 전달되어 주연료로서 사용된다. 소가능한 가스내로 기수공발되는 휘발된 납은 정련로와 연관된 회복 및 환경보호/제어장비로 운반된다. 한편으로, 납 오염된 오물은 플라즈마 아아크에 의해서 비독성(독성 리칭 절차(Toxicity Characteristic Leaching Procedure)에 따름)의 유리화된 슬래그로 전환되는데, 유리화된 슬래그는 분쇄되어, 시판용 재료(즉, 도로 포장재, 아스팔트 충진재 등)로서 사용되거나, 또는 환경에 위협을 끼치지 않는 쓰레기 매립지로 간단히 운반된다.
