Each kinds of the leather process wastes which is occurred in the leather making process is almost more than 50% on the basis of the raw hide. The emitted process wastes are important oil and fars and prorein resources because they are composed of animal oil and fats and fìbrous protein. But most of them are incinεrate or filled up simply as the indusuial wastes without applying to recycling into the other use. Thus the ptoblems of environmental pollution are becoming more crirical and the processing cost of the leather process wastes (40,OOO~ 60,OOO won) is a heavy burden on the production cost. Because the organic wastes such as f1eshing scrap, pelt scrap are high fetid, irs unlawful abandonment without being processed properly causes the occurrence of secondary pollution byan offensive odor and leakage of waste water. Thus we made the re-resource experiments in order to resolve this problems. The principal comems of this srudy are to process the collecred leather wasre scrape through separate the oil and far ingrediems with varlous properη by processing various chemicals and enzymes on rhe next effecror. The re-resource application of separated oil and fat ingrediems produced chemical for leather applicable ro manufacturing process of leather through chemical transformation process(sulphation reaction, sulphitation reaction etc.) of oil and fats. 피혁 제조 공정에서 발생되는 각종 피혁 가공 폐기물의 발생율은 원료피 기준 거의 50% 이상이며 배출되는 피혁 가공 폐기물들은 50% 이상의 수분을 함유한 동물성 유지 및 섬유상 단백질로 구성되어 있어 귀중한 유지 및 단백질 자원임에도 불구하고 다른 용도로의 재활용 적용 없이 대부분 산업 폐기물로 소각하거나 단순 매립 처리하고 있다. 이로 인해 이 들 피혁 가공 폐기물에 의한 환경오염 문제가 날로 심각해져 가고 있는 실정 이며 피혁 가공폐기물에 대한 과다한 처리비용(4만원 ~6만원/Ton)으로 생산 원가 측면에 서도 큰 부담이 되고 있다. 더욱이 Fleshing scrap, Pelt scrap과 같은 유기성 폐기물의 경우는 부패성이 높아 적절하게 처리되지 않고 불법투기될 경우에 발생하는 악취, 오수 누출 등에 의한 2차 오염이 발생됨으로 이러한 문제점을 해결하고자 재자원화 실험을 실시하여 유지 및 단백질의 재회수 기술 개발과 이를 이용한 재 자원화 기술 개발로 피혁 처리용 약품을 제조하였다.
