Hitachi Construction Machinery


Raw Material Procurement

In order to continue to lower environmental impact across the supply chain, we have been advancing green procurement through a policy of putting the priority on raising supplies through companies that are proactive in promoting environmental initiatives.

As most of the company’s products are based in construction machinery, and are made of metals such as iron etc., HCM is focusing its efforts to make more effective use of these limited resources.
In the course of processing metal materials, HCM aims to reduce its level of defects in casting, and in turn is working to reduce the amount of raw materials used overall. In addition, HCM continues to improve the durability of its products across many aspects, such as increasing the rigidity of the front structure of hydraulic excavators, and further promoting the more effective uses of raw materials.

Total weight of raw materials for the past 3 years are ; 253,000t in 2017 and 318,000t in 2018 and 115,700t in 2019.
Bradken has been included in the results since FY 2018.
