Reducing Industrial Waste
The main types of environmental load in the RIKEN TECHNOS 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 targets of reducing the ratio of simple waste to total production to 0.1% or less and reducing the ratio of total waste to total production to 3.3% or less. 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, raw cement material, and such for conversion to effective use.
Our target is to limit the ratio of total waste to total production to 3.0% or less by FY2030, and we have set progressive reduction targets each year and are working on steady reduction. We will continue to implement initiatives toward achieving our target.

Reduction of Industrial Waste and Promotion of Recycling
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.
