펄프제지공업의 특성

자본집약적 산업 (capital intensive industry) 판매 제품의 이윤이 적음 (small profit margins) 새로운 기술을 공정에 적용하는데 소극적 (limit

experimentation, developments, and incorporation of new technologies into the mills)

다량의 공업용수를 사용함 (3rd ranks following the metals and chemical industry)

폐수 처리 시스템을 가동하여 폐수의 방출량을 줄이고 있음.
