Circular resource
Overview and business progress
The environmental business is a project aimed at pursuing sustainability by using waste resources generated in the process of industrial activities, including daily life waste, as fuel for the cement manufacturing process to conserve resources and use recycled resources. To this end, we have continuously invested in facilities to increase the use of waste tires and synthetic resins, and in recent years, the use of recycled resources has been made through efforts to establish infrastructure for environmental projects such as waste heat recovery power generation, energy storage (ESS), and combustion facility renovation. We are leading the paradigm shift toward a circular economy.
