Waste Reduction

Concept and Performance

Idemitsu Group works on reducing environmental impact by reducing the volume of industrial waste generation and by promoting the reuse of raw materials and the utilization of recycled raw materials from the perspective of the effective use of resources.
Major wastes generated by our businesses include waste catalysts used in refining processes at refineries, sludge from tank cleaning, and sludge from wastewater treatment facilities. On the other hand, we reduce the volume of these wastes and make them harmless through intermediate treatment such as incineration, dehydration and dissolution, and promote their reuse as raw material for cement, continuing "zero emissions" to reduce the final disposal volume of wastes to 1% or less.

  • * The final disposal rate at Idemitsu increased significantly since FY2017. This was mainly due to the disposal of materials generated by the removal of the oil refining equipment (suspended in March 2014) and others in Tokuyama Complex. The disposal is scheduled to be completed by FY2020.
