Offensive Odor Regulation and the Technologies Used to Clear the Target at Local Pulp Mills in Japan

Abstract

37 kraft pulp mills are operating in Japan. The offensive odor emission has been under control of the law since 1972. As local governments can modify the national law, and specify their own limit values for odor emission, depending on their local requirement, a survey was made to know the limit value and the technologies used to clear the target at each mill. The survey covers all kraft pulp mills.
