Abstract
Japanese modern waste management started for the purpose of keeping “public health” extended the role to “environmental conservation” and “proper treatment”, corresponding to the economic growth. Establishment of a “sound material-cycle society” becomes the target of waste management to solve the global environment problem and to build “sustainable society.” “Reduce, Reuse and Recycle” are major contents of the policy for sound material-cycle society, but 3Rs should involve not only waste management but also resources conservation. The information of 3R should be fed back to design and usage of products.
