Recycling and better listening experience

Increasing the use of recycled plastic is part of our environmental plan to achieve a zero environmental footprint. We're introducing a new recycled plastic that will contribute to the further use of recycled material in audio products by helping to deliver high-quality sound.

Meeting the challenges of sound

Sony uses recycled plastics in a growing variety of product categories. The premise of this is our mission to provide a moving experience for our users. The high expectations that our users have toward the performance of audio products encouraged us to create a new high-performance recycled plastic for audio. 

Passionate about technology and the spread of recycled plastic

Sony's engineers were pursuing both sound quality and environmental awareness when developing this material. Watch an interview with those involved, and discover what factors resulted in this innovation.

Improving sound quality while using 65% recycled materials

Among the recycled plastics that we use, one offers a recycled material usage rate of 65%. Based on this, this new recycled plastic maintains that high rate while helping to improve sound performance by testing new combinations and ratios of additives.

Ensured impact resistance

For products where various usage situations are expected, sufficient impact resistance is a necessity. The new recycled plastic material delivers resistance comparable to virgin plastic.

Trustworthy material, first and foremost

By limiting the recycled material for our new recycled plastic to specific pre-consumer items, we ensured a stable supply, productivity and quality for the new recycled plastic, which is capable of delivering superior audio performance.
