Reducing Industrial Waste

The main types of environmental burdens in our Group's business activities come from greenhouse gas CO2 emissions and the discharge of industrial waste and chemical substances, and we strive to reduce and manage them properly.
Based on the scope of ISO 14001 certification, we consider the Company's non-consolidated reduction of simple (landfill and incineration) waste generated in the manufacturing stage to be one of the main goals of environmental management activities, and have been working toward the goals of reducing simple waste volume per gross production to 0.1% or lower and reducing total waste per gross production to 3.5% or lower. We are promoting restraint in generating waste by improving yields in our production processes, as well as strictly separating generated waste into material recycling, thermal recycling, Refuse Plastic Fuel (RPF), raw cement material, etc. for conversion to effective use.
Since FY2023, we have been working on reducing the total waste per gross production volume by 0.1% annually toward the RIKEN TECHNOS CORPORATION's goal to limit the figure to 3.0% or lower by FY2030, and will continue to work toward this goal.
