Mitsubishi Materials is advancing initiatives to reduce GHG emissions from a wide range of perspectives, including new R&D and management of company-owned forests. Here, we will introduce efforts to reduce GHG emissions.

In our Metals business, which accounts for approximately 60% of domestic power consumption within Mitsubishi Materials Group, there are plans to switch all purchased electricity to renewable sources by the fiscal year ending March 2029. Additionally, we have installed solar power generation facilities at Akashi Plant (Hyogo Prefecture) and Ecomanagement Co., Ltd Myoho Mine Office (Wakayama Prefecture) through on-site services (PPA model) and are using the electricity generated for our business activities.

Mitsubishi Materials is advancing research and development on carbon recycling processes. In experiments conducted in 2018, we successfully decomposed CO2 and recovered fine carbon nanomaterials. These carbon nano- materials hold promise for various applications such as tire reinforcement materials and battery materials. Moving forward, we will continue to create innova- tive processes that enable the reuse of CO2.

Developing environmentally friendly products and technologies is also one of our strengths. The “Mitsubishi Process” for continuous copper smelting, a world-renowned technology, is a pollution-free system that prevents the emission of sulfur dioxide gas. Additionally, our recycled metal brand, “REMINE,” a first of its kind in Japan, offers non-ferrous metal products with higher reliability, achieved through calculations of recycled material content in compliance with international standards and verification by third-party organizations. Starting from January 2024, we have begun selling the first batch of REMINE products, including Refined Tin with 100% recycled material content and Refined Lead with over 99.6% recycled material content.

Mitsubishi Materials owns 14,000 hectares of Materials’ Forests in Japan, and timber production and afforestation are carried out while conserving biodiversity. Forests play an important role in environmental conservation through carbon fixation and other mechanisms. Among them, our Teine Forest (Hokkaido) has been recognized for its adoption of a work system with low environmental impact on forest management and has received certification as a Natural Symbiosis Site by the Ministry of the Environment.
