A sound choice for the environment

Engineering audio for future generations

Sony's audio products are engineered for exceptional sound, and with the environment in mind.
Under our Green Management 2025 targets, we aim to reduce virgin plastic consumption in all our product and packaging designs.

Recycled materials in products

Serious about sound and the environment

Sony Home Audio products such as soundbars and speakers utilise recycled plastics to reduce the amount of virgin plastic used.
The choice of material affects sound quality in particular, so we have spent years developing a unique recycled plastic that is both environmentally conscious and conducive to creating high-quality audio products.

Developing recycled plastic

Our recycled plastic is recovered from discs and water cooler bottles.
The reclaimed plastic is removed of any films or coatings, and then used as a base material. Aiming for uncompromising audio quality, we tested a wide variety of combinations to determine the best possible solution for audio products.

Reducing virgin plastic use in soundbars

Our new soundbar utilises recycled plastic for various components. As a result, it uses approximately 45% less virgin plastic than the previous model.

Towards a future with more recycled plastic

We use recycled plastic in the exteriors and interiors of a variety of our audio products. We plan to continue researching and developing new ways of utilising recycled plastics, to deliver products that offer top-notch sound while supporting environmental efforts.

Environmentally conscious packaging

We are working to reduce the amount of plastic used in packaging by utilising recycled paper materials such as for cushioning and inserts, and by using paper-based handles.

Reduction of virgin plastic in new soundbar cartons

The packaging carton for our new soundbar uses 65% less virgin plastic than the previous model. We also reduced the amount of printing, resulting in a 65% reduction in the amount of ink used. The aim is for packaging that is both environmentally conscious, durable and beautifully designed without compromising functionality.

We have been working on the use of recycled plastics in home audio since around 2010. While improving their performance to a level that matches that of virgin plastics, we worked on design aspects, and made these recycled plastics usable in actual products. In 2016 we developed a recycled plastic, used for internal components in our products, which also takes sound quality into account.

 However, further expansion of the use of recycled plastics required that we expand the scope of their application. The material that we have newly developed on this occasion is flame-retardant. During the development process, we pursued the idea of how closely we could approach the sound quality of the materials we used previously. By examining many configurations, repeatedly prototyping and testing strength, we were able to create a material that satisfied the sound quality and physical requirements of the product.
