廃棄物の再資源化対策

抄録

According to the waste flow of manufacturing industry (cf. Chart-1), the discharge of “industrial waste” and that of “house hold waste” is 252, 660, 000t and 46, 470, 000t each, and the final (1987 fiscal year) disposal of industrial waste and household waste is 36, 350, 000 t and 16, 490, 000t each.
43.2% of “industrial waste” is recycled, and 42.4% of that is reduced by in-termediate treatment. So only 14.4% of total discharge is final disposal. On the other hand, 60.9% of “household waste” is reduced by intermediate treatment, and the rest is nearly final disposal.
Final disposal of waste is mostly depend on reclamation. Final disposal sites for reclamation are reserved and have good capacity in the whole country. But near large cities, securing them is difficult, for example in Tokyo area it is estimated that they will be full of household waste in 4.2 years and will be full of industrial waste in 0.8 years.
The ministry of international trade and industry financially aids the recycling test plant. MITI requires 1991 fiscal year budget of test plant as twice as that of 1990, moreover requires the budget for expenditure to make the new recycle products, expenditure to make the recycle system and the aid for the development of efficient technology of generation of electricity by waste.
