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 2022, Hitachi Construction Machinery Group reduced amount of waste and valuables generated by 4.4% compared to the previous year.
We define waste under the Basel Convention as hazadous waste , the amount generated was 202 tons in FY2021 and 165 tons in FY2022 .

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 3 production bases in Japan reached the FY 2022 zero emissions target;
Hitachi Construction Machinery Kasumigaura Works, Banshu Works, Hitachi Construction Machinery Camino. And as oversea bases, Hefei Rijian Shearing Co.,Ltd., Hitachi Construction Machinery Indonesia, Hitachi Construction Machinery Europe and BRADKEN INDIA PRIVATE LIMITED achieved zero emissions target.
Reuse and Recycling of Used Products
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 recycling rate as important management indicator, and each base promotes thorough sorting and reuse with the aim of becoming a zero-emission factory.
