Abstract

Asbestos or its applications have been used for long times and for various purposes in our life because of their merits, namely fire resistance, electric insulation and chemical resistance capacity etc. Despite of theses many merits, one of the problems of asbestos is shown toxicity according to its fiber type. So we need data to solve about this problem. In this paper, we study on the technical method of asbestos waste treatment and on the trends of asbestos researches and developments by the analysis of its patents and DWPI database materials. As a result, the asbestos-waste treatment data in the its related patents is used 267 cases to analyze. These data are divided into 86(32.5%) cases of solid waste disposal(B09B). 41(16.6%) cases of separation(B01D) and 27(10.2%) of lime, magnesia, slag, cement and their composites(C04B).

석면은 내화성, 전기에 대한 절연성 및 화학약품에 대한 저항성이 강하여 산업 전반에 걸쳐 다양한 용도로 우리의 생활 주변에서 흔히 사용되어 왔다. 그러나 석면은 석면섬유형태에 따라 독성을 보여주고 있다. 본 논문은 석면 폐기물의 처리 기술과 환경오염 문제해결을 위한 기술동향 정보를 제공할 목적으로 KISTI에서 운영하는 특허 검색시스템을 사용하여 DWPI Database에서 석면 폐기물 처리기술을 검색 및 분석을 하였다. 그 결과, 석면 폐기물 처리에 관련 특허 분석 대상은 267건 검색되었다. 이들 중 고형 폐기물 처리(B09B)분야에서 86건(32.5%), 분리(B01D)분야에서 44건(16.6%) 및 석회, 마그네시아, 슬래그, 시멘트 및 그 조성물(C04B)분야에서 27건(10.2%)을 보여 주었다.
