Reducing Industrial Waste

The Mitsui Chemicals Group aims to minimizing industrial waste at domestic production sites and overseas affiliates, aiming for an average final disposal (landfill) rate for industrial waste of 1% or less.
The Group was again successful at minimizing industrial waste at all domestic production sites including domestic affiliated companies in fiscal 2016 and has continued to minimize industrial waste for six consecutive years since fiscal 2011.
With an average landfill rate for final industrial waste at our overseas affiliates of approximately 0.4%, we have now maintained a rate of 1% or less for eight 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.
