Abstract
This article shows an overview of the technologies available from materials science as a means of achieving the ultimate goal of creating a Circular Economy. This concept holds almost the same meaning as that of The 3Rs (Reduce, Reuse and Recycle) in Japan and the order of priority is also the similar. Eco-design must be promoted within this and all of the various other technologies need to be very diverse. There must be a framework for the technologies being used and the present states of recycling for raw materials, which are highly mass-produced like plastics, steel and iron, aluminum, other non-ferrous metals and glasses.
A production process for the preparation of compounds containing recycled plastics is needed for plastics recycling. Pre-treatment technologies are desired to get the same performance as primary resource production. Physical separation processes are important for aluminum alloys and glass in particular because they are very difficult materials to harness in the melting process. Development of evaluation technologies for environmental impacts is also crucial.
