The 8 production bases which reached the FY 2020 zero emissions target are following: Hitachi Construction Machinery Tsuchiura Works,  Kasumigaura Works, Hitachinaka Works, Ryugasaki Works, Banshu Works, Hitachi Construction Machinery Tierra, Hitachi Construction Machinery Camino, and Tadakiko. And as oversea bases, Hefei Rijian Shearing Co.,Ltd., Tata Hitachi Construction Machinery Company Private Limited, Hitachi Construction Machinery (Europe) and P.T. Hitachi Construction Machinery Indonesia achieved zero emissions target.

Reuse and Recycling of Used Products

Promoting a Transition to IT-based Management of Waste

The Hitachi Construction Machinery Group is promoting a transition to IT-based control of waste products in our efforts to raise the compliance level benchmark and streamline the administrative work related to appropriate waste disposal. We are working on initiatives to raise the electronic manifest issuance rate.
The 10 locations that achieved 100% of the rate published in the FY 2020 electronic manifest are Hitachi Construction Machinery Group Tsuchiura Works, Kasumigaura Works, Ryugasaki Works, Hitachinaka Works, Hitachinaka-Rinko Works, Banshu Works, Hitachi Construction Machinery Tierra, Hitachi Construction Machinery Camino, Tadakiko, and Shin-Tohoku Metal.

Ongoing Initiatives

Most of our waste is valuable resources such as cutting boards. Aiming for 100% recycling of waste other than valuable resources is also  important from the perspective of environmental protection and the circular economy. At our company, we set the final disposal amount and landfill rate as important management indicators, and each base promotes thorough sorting and reuse with the aim of becoming a zero-emission factory.
