Sony Builds Global Renewable Plastics Chain

Sony and 13 chemical and materials companies have established what they describe as the world’s first global supply chain dedicated to renewable plastics for high-performance audio-visual products, spanning 14 companies across five countries and regions.

The network includes Mitsubishi Corporation, ADEKA Corporation, CHIMEI Corporation, ENEOS Corporation, Formosa Chemicals & Fibre Corporation, Hanwha Impact Corporation, Idemitsu Kosan Co., Ltd., Mitsui Chemicals, Inc., Neste Corporation, Qingdao Haier New Material Development Co., Ltd., SK Geo Centric Co., Ltd., Toray Industries, Inc. and Toray Advanced Materials Korea Inc. Renewable plastics produced through the supply chain are slated for use in Sony products to be launched worldwide.

The initiative maps the full value chain from feedstock to finished goods. Neste Corporation produces renewable naphtha, followed by renewable styrene monomer from Idemitsu Kosan and renewable polystyrene resin from Formosa Chemicals & Fibre. SK Geo Centric and ENEOS produce renewable para-xylene, which is converted into renewable terephthalic acid by Hanwha Impact and renewable PET resin by Toray Advanced Materials Korea. Mitsui Chemicals manufactures renewable bisphenol-A, CHIMEI produces renewable polycarbonate resin, ADEKA supplies renewable flame retardants and Qingdao Haier New Material Development manufactures renewable PC/ABS resin before molding and final product design and manufacturing by Sony.

High-performance electronics rely on multiple engineered plastics with strict flame resistance and optical requirements. Sony said recycled plastics cannot fully replace virgin fossil-based materials in such applications, limiting efforts to reduce fossil inputs.

To address this, the companies redesigned the supply chain around biomass-derived feedstocks using a mass balance approach, allowing renewable content to be tracked across production stages while maintaining properties equivalent to virgin plastics. Defining the supply chain also enables participants to track and document greenhouse gas emissions data in a verifiable manner and use the data to support carbon reduction strategies.

The collaboration forms part of the “Creating NEW from reNEWable materials” project jointly launched by Sony and Mitsubishi Corporation, which aims to eliminate virgin fossil-based plastics in Sony products over time. “We chose this method because it does not change the quality of the product. What changes is the feedstock of the materials we use. This fundamentally changes how products are made, which is why the entire supply chain must work together,” said Hisaoki Ohba, Sustainability Representative, Sony. 

Sony and its partners said they will continue promoting renewable plastics in high-performance products as regulators and investors increase scrutiny of Scope 3 emissions and lifecycle disclosures. The mass balance model allows renewable feedstocks to be integrated into existing manufacturing infrastructure, potentially supporting broader adoption across electronics and other industrial sectors.
