Sony has experimented with different materials and technologies in the past, and continues to refine them.Product Packaging TechnologyThis strengthens environmental sustainability. At the Sony Music Group's Sustainability Day 2025 event held in Japan earlier on November 28th, the group further showcased its various environmental and social contribution activities. Among them, the most eye-catching for audiophiles and tech enthusiasts was a product made from recycled waste fiber products."Environmentally Considered Turntable" Prototype.
Discarded uniforms transformed into audio equipment, with a hardness comparable to MDF.
The prototype's base frame (Cabinet) is made from recycled fiber materials such as discarded employee uniforms and event banner strips, which are then compressed and molded into a sheet material. According to Sony representatives, this special sheet material has the same rigidity as MDF (medium-density fiberboard) commonly used in audio equipment.
The most unique feature is that the acoustic characteristics of the base change depending on the type and mixing ratio of the fibers used, which in turn affects the "timbre".
The prototype on display was modified from parts of Sony's "PS-HX500" turntable, which supports Hi-Res recording. The developers pointed out that this material produces a smoother sound compared to regular turntables, making it a better match for the characteristics of analog records.
Furthermore, its appearance design differs from the monotonous black commonly found in traditional recycled resin products. By directly retaining the original fiber color, the surface exhibits a unique texture and color, creating visual differentiation.
The "Rebloom" project recycles congratulatory flower baskets from concerts, extending the life of the flowers.
The event also showcased a previous project called "Rebloom Flower Project," which mainly involves recycling the large number of congratulatory flower baskets received at concerts or events and reprocessing them into dried flowers, potpourri, perfumes, or diffusers.
As of October this year, the project has recovered approximately 1300 kilograms of flowers and given them new life through workshops and the creation of merchandise. This project is not only being implemented within the Sony Group but is also beginning to expand to the performance activities of artists from other agencies.
By incorporating OBM materials, the plastic content of disc trays is reduced by 97%.
For physical optical disc media, Sony also showcased a high-precision disc tray made from its own "Original Blended Material".
This material is made from a blend of bamboo, sugarcane fiber, and recycled waste paper. The newly designed paper tray reduces plastic usage by 51% in the clamping part that holds the discs, and by up to 97% compared to traditional plastic trays, it reduces the use of petroleum-refined plastics, significantly reducing the environmental burden while the demand for physical media remains.
