Industrial Waste

The Mitsui Chemicals Group aims to minimize industrial waste at domestic production sites and overseas affiliates, aiming to minimize the landfill disposal rate for industrial waste at 1% or less.
The Group was again successful at minimizing industrial waste at all domestic production sites including domestic affiliated companies in fiscal 2017 and has continued to minimize industrial waste for seven consecutive years since fiscal 2011.
With a landfill disposal rate for industrial waste at our overseas affiliates of approximately 0.3%, we have now maintained a rate of 1% or less for nine straight years since fiscal 2009. In spite of the numerous challenges that we need to overcome to promote minimization at our overseas sites, including waste treatment regulations and industrial structures varying from one country to another, we are nonetheless committed to reducing and recycling waste at all of our companies in order to conserve resources. We will continue to work as a group to reduce final landfill waste.
