Our twin objectives are to deliver exceptional products, and minimize their environmental impact, in line with our Road to Zero environmental goals. We developed recycled flame-retardant plastic SORPLAS to achieve these objectives.
SORPLAS is made from used water bottles and waste optical discs collected from factories and markets, and a proprietary flame retardant. It’s used in a variety of Sony and external products. SORPLAS won’t degrade too much even after being recycled several times, so in the future, it’s expected that SORPLAS will be recovered and reused in new products.
Crushed waste optical discs from disc manufacturer Sony Music Solutions Inc. are one of the ingredients of SORPLAS, used for the rear covers of Sony’s BRAVIA™ TVs.
Sony’s recycled plastic SORPLAS is safe, reliable, and its performance in products matches that of virgin plastics.
Recycled plastic used in electronics is typically only around 30% recycled content. Our ground-breaking sulphur-based flame retardant produces consistently high-performance plastic even when using up to 99% recycled content.
 Recycled content 99%  Flame retardants, other additives 1%
 Typical flame-retardant recycled polycarbonate plastic
 Recycled content 30%  Petroleum-based virgin plastic 55%  Flame retardants, other additives 15%
CO2 emissions from production of SORPLAS can be reduced by approximately 72% compared to flame-retardant virgin plastic production used in the same application.

In the various products that add colour to our lives, durability and aesthetics also matter. As well as providing solid durability, SORPLAS has a good surface appearance, and can maintain its quality over long periods of use.
SORPLAS achieves high recycled content while also providing durability due to its lower flame retardant content, and a beautiful non-fading exterior finish for BRAVIA TVs.
We have developed a special grade of resin suitable for TV rear covers which exhibits excellent strength and design, overcoming a challenge for recycled plastics. We’ve also done it while using an industry-leading recycled material ratio.
Since smartphones are used in a variety of environments, they must be both robust and durable.
Prioritizing high strength and durability, even compared to virgin plastic, has allowed SORPLAS to be adopted for major internal parts.

SORPLAS was born from research that began about 20 years ago, based on a strong desire to convert waste plastic from business sites into a resource with high added value. First, we had to make practical a proprietary flame retardant that shows high flame retardancy in polycarbonate resin with extremely small amounts. SORPLAS blends that flame retardant and various additives with recycled materials such as used water bottles and waste optical discs from factories and markets, to create a flame-retardant recycled plastic with beautiful luster and high durability while achieving up to 99% recycled content. SORPLAS with a wide variety of resin properties has already been put to practical use, but going forward we will continue development to expand the range of applications and contribute further to the environment.
