With recent development of the petrochemical industry, plastic product
s have made our society more convenient. However, the disposal of thes
e convenience products has become a serious threat to the environment.
Therefore, research on recycling plastic wastes is necessary now more
than ever. This paper is a basic study of recycling technology for AB
S (acrylonitile-butadienestyrene) resin. We tried to show the changes
in its mechanical, thermal, theological, and optical properties during
the recycling process.
