Sigma adopts a biomass-derived polycarbonate resin as part of its commitment to more sustainable manufacturing

Sigma Corporation (CEO: Kazuto Yamaki) is advancing its commitment to sustainability by switching from a conventional petroleum-based resin to a biomass-derived alternative for the production of its proprietary material, Thermally Stable Composite (TSC). This shift significantly reduces the environmental impact of Sigma's manufacturing processes.

Effective immediately, the transition to a biomass-derived polycarbonate resin applies to all products incorporating TSC, including the Sigma 24-70mm F2.8 DG DN II | Art. These products will begin shipping in the first half of the Japanese fiscal year 2025. As a result of this change, approximately 40% of all plastic components produced at Sigma's sole manufacturing facility in Aizu, Japan, will utilize this sustainable material.

TSC is Sigma's proprietary composite material and is designed to combine high strength with outstanding thermal stability. Its excellent compatibility with metal components helps ensure high-precision engineering, superb optical performance, enhanced durability, and significant weight reduction.

By adopting a biomass-derived polycarbonate resin, Sigma is able to maintain the exceptional performance characteristics of TSC while taking meaningful steps to significantly lower its greenhouse gas emissions and reduce its overall environmental footprint.

This change reflects Sigma's wider commitment to sustainability, with ongoing investments in environmentally responsible facilities, equipment, and technologies.
