Reducing Waste Products
To contribute to the effective utilization of resources, Hitachi Construction Machinery Group is working to reduce the waste which accompanies business activity.We are proactively promoting the 3R’s (reduce, reuse, recycle) while putting a focus on production locations, the minimization or avoidance through the effective use of raw materials and resources taken from nature. We also aim to realize a circular economy while reducing waste (including hazardous waste) by using recycled materials, reusing and recycling products and parts.
In FY 2021, Hitachi Construction Machinery Group reduced amount of waste and valuables generated by 4% compared to the previous year.
We define waste under the Basel Convention as hazadous waste , and the amount generated in 2021 was 202 tons.

Total Range: Main Domestic and Overseas Production Bases for Consolidation
Zero Emissions Achievement Office
Manufacturing bases are working on a zero emission program. The zero emissions performance criterion for the Hitachi Construction Machinery Group is a maximum final disposal rate of 0.5% (landfill disposal levels/waste product generation levels) for the fiscal year.
The 4 production bases which reached the FY 2021 zero emissions target are following: Hitachi Construction Machinery Hitachinaka Works, Hitachinaka-Rinko Works, Banshu Works, Hitachi Construction Machinery Camino, and Tadakiko. And as oversea bases, Hefei Rijian Shearing Co.,Ltd., Tata Hitachi Construction Machinery Company Private Limited and BRADKEN INDIA PRIVATE LIMITED achieved zero emissions target.
Reuse and Recycling of Used Products
Promoting a Transition to IT-based Management of Waste
In the FY 2021, all Japan domestic production bases; 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 achieved 100% of the rate published in electronic manifest.
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.
