Technology:
Sharp established a technology to recycle high-performance resin polycarbonate ABS
resin used in flat-screen TVs. Because prolonged use deteriorates polycarbonate
ABS resin, it cannot easily be recycled for home electric appliances. The
company developed an additive to recover the deterioration in collaboration
with Kansai Recycle Systems in Hirakata city, Osaka Prefecture. This additive allows
used polycarbonate ABS to recover almost the same product characteristics as
new one, and the cost to recycle polycarbonate ABS with this additive is
expected to be the same as the cost to use new one.

Polycarbonate
ABS accounts for more than 50% of all resins used in flat-screen TVs. Although it
is a major material characterized by impact resistance and flame resistance, it
is currently recycled for only sundries because of the difficulty of recycling.
Sharp plans to use recycled polycarbonate ABS for new flat-screen TVs, but only 3
million flat-screen TVs are being recovered annually at present, a well below the break-even
point for recycling. Accordingly, recycled polycarbonate ABS will presumably be applied to
new flat-screen TVs beginning in 2018. In the initial stage, it will be used
for in-car air-purifiers.
