韓国・中国における農業廃プラの回収・処理とリサイクル

抄録

Funatsu studied the collection and disposal systems and activities of waste agricultural plastics (WAP) in Japan, Korea and China, presenting several important views. This study re-examined the conditions in these countries and further identified these views as well as new issues. First of all, while the public corporation (ENVICO), which collaborated with local governments, set up many WAP collection points in rural areas, most farmers discharged wastes not at the designated points but rather around their fields. Second, farmers in China leave most low quality WAP around their fields due to lack of collection systems; higher quality WAP is collected by private collectors. Third, differing from Japan, one big reason that WAP are treated as resources in Korea and China is that the farmers, as resource possessors, need not to take responsibility for their proper disposal. Fourth, although Funatsu prescribed that all operations should be dealt with positive pricing, in fact, only high quality firms used positive pricing. ENVICO must give incentives which come from tax and levy to the farmers for WAP collection. Fifth, Korea pursues domestic recycling of all quantity of WAP as the resources introducing material and thermal recycling, although Funatsu described this as oriented toward exports. This also differs from Japan, where reclamation, incineration and recycling are conducted. Sixth, before considering the connected East Asian system as Funatsu described, there are many problems to solve in China alone.
