Statistical Survey on Industrial Wastes and its Utilization in Pulp and Paper Mills in Japan

摘要

Japan Paper Association surveys statistics on industrial wastes disposed from pulp and paper mills every year by sending a questionnaire to each mills. The result in the 2000 survey is as follows. 1. The coverage is 88.4%, based on the paper production volume. It is the highest figure in these several years. 2. The total industrial waste generated, that is the sum of industrial waste reused and industrial waste finally disposed, increased 6% in B.D. weight compared to that in the 1999 survey. It is due to paper production increase of 10% in 2000. 3. The waste rate is 81%. The waste finally disposed reduced 11% in B.D. weight compared to that in the 1999 survey. 4. When compared to the 1989 survey, following improvements are remarked. (1) The unit industrial waste generation is 22% less than that in 1989. (2) THe water contennt of the industrial waste generated is reduced to 30% from 50% in 1989. (3) The unit waste finally disposed is 80% less than that in 1989. 5. The guideline by Japan Paper Association for waste reduction is that the waste finally disposed in 2010 should be reduced to 450 thousand tons (as it is) from 2537 thousand tons in 1990. It is 612 thousand tons in 2000.
