CSR Promotion Guidelines

Realization of a Carbon-Neutral Society
Proposal of raw materials effective for CO2 reduction measures

01Utilization of Hydrogen and Ammonia for Decarbonization
As various companies are working on hydrogen energy, which can reduce environmental impact and be utilized in times of disaster, Inoue is actively engaged in materials that enable the storage of hydrogen under special conditions, contributing to the construction of a low-carbon society.
  • We are working with our customers on research and development of gas turbines for hydrogen and ammonia power generation.
  • We provide metals used in "hydroelectric and geothermal power generation."
  • We are a comprehensive distributor of "Super Insulation" that can be used with hydrogen.
02Proposal of Materials for Extending the Lifespan of Plants
We propose optimal materials such as nickel alloys to solve the issue of rusting in iron, the main component of plants, thereby contributing to the extension of plant lifespan. By considering cost performance and usage conditions, we suggest using different base materials for each part, enabling effective cost reduction.
03For the Development and Promotion of Next-Generation Energy Generation
We propose optimal metal materials and processing methods.
Through processing services in collaboration with partner companies and metal materials, we support the development and promotion of next-generation energy generation and contribute to decarbonization.
04Supporting the Improvement and Enhancement of Industrial Infrastructure with Proposals for Stainless Steel Materials That Require No Painting and Have Low Corrosion
Through processing services in collaboration with partner companies and metal materials, we support the resolution of challenges in various industrial infrastructures and contribute to sustainable business operations.
05Providing Optimal Material Procurement Services to Manufacturing Startup Companies
With the aim of supporting the growth of outstanding manufacturing startups, Inoue offers materials that can be utilized to strengthen Japan’s technological capabilities and contribute to the development of an industrial structure that is competitive on a global scale.
06 Procurement of Products in Accordance with the "Hitachi Group Sustainable Procurement Guidelines"
Regarding material procurement, we follow the "Hitachi Group Sustainable Procurement Guidelines" established by our major business partner, Hitachi, Ltd. We strive to prioritize the purchase of environmentally friendly products, parts, and materials.
