Efforts to curb the consumption of natural resources and reduce waste have acquired greater social urgency, reflecting wider economic activity and population growth.
By promoting resource efficiency in its products and manufacturing processes, Kawasaki takes great care to effectively utilize and recycle the planet’s finite resources.
Through ongoing initiatives in our business activities and efforts to promote their penetration in workplaces, we have maintained landfill disposal and recycling rates at our target levels.
10th Plan Target
Maintain ratio of direct-to-landfill waste to total waste generation at less than 1% (non-consolidated)
Realization of a Low-Carbon Society
Further enforce waste sorting and recycling
Improve Group-wide management
Precisely understand water uses and usage volumes
Confirm water resource risks
Reduction of Total Waste Generation
We are continuing activities to achieve our targets to reduce waste generated through our manufacturing processes per unit of net sales by using resources effectively, and to achieve zero waste disposed of in landfills through the promotion of recycling.
In fiscal 2019, by making changes to product packaging, we reduced waste and eliminated the need to sort cardboard and foam, facilitating recycling. Total waste generated and the landfill disposal rate (the ratio of waste disposed of in landfills to total waste generated) are shown in Figure 17. The landfill disposal rate was 0.2%, achieving the target of 1% or less.
Response to Japan’s Resource Circulation Strategy for Plastics
Kawasaki recycles and properly treats the waste plastics that it produces as industrial waste. In 2019, the Japanese government formulated a strategy for plastic use that includes the basic principles of “3Rs + Renewable.” Going forward, Kawasaki will consider how these principles apply to its businesses in areas other than waste management as it works to help solve social issues.
Promoting PCB Treatment
The disposal of PCB (polychlorinated biphenyl) waste is proceeding worldwide, in line with the Stockholm Convention, which includes stipulations on the proper treatment of PCBs. In Japan, disposal is undertaken in a systematic manner, mainly by the Japan Environmental Storage & Safety Corporation (JESCO), which was established by the Ministry of the Environment. The phased disposal period for high-concentration PCB waste is scheduled to end in 2022, and that for low-concentration PCB waste will end in 2027. We are undertaking the treatment of our PCBs, aiming for completion ahead of the national schedule. To achieve our disposal targets, we are steadily ceasing use of equipment that contains PCBs (low-concentration PCB waste), putting such items into storage, and working with treatment service providers.
Precisely Understanding Water Uses and Usage Volumes
To more effectively use water resources, Kawasaki is advancing efforts to precisely understand water usage at each of its plants.
Water consumption in fiscal 2019 came to 5,983,000 m3 (Figure 18). We are reexamining our uses of water, such as in production activities and boilers, as we explore ways to promote more efficient and effective water use. By rolling out these initiatives across the Group, we will reduce water-related risk.
