Sony Corporation, Japan, is putting on the market its innovative inorganic flame retardant recycled plastics SORPLASTM (Sustainable Oriented Recycled Plastic). The material is up to 99% recycled polycarbonate from waste optical discs and optical sheets (light-diffusing films) from LCD screens, as well as post-consumer materials like used plastic water bottles. Fire safety is achieved using Sony’s proprietary sulphur-based flame retardant at <1% loading.
Sony has already been using SORPLAS in its own products (e.g. BRAVIA LCD TVs, Handycam camcorders). The material offers better technical performance than standard FR polycarbonates and environmental advantages including an 80% reduction in CO2 emissions compared to using virgin polycarbonate and multiple recycling potential, with no significant deterioration of mechanical properties after repeated repelletising.http://www.sony.net/SonyInfo/News/Press/201408/14-073E/index.html
