Reducing Emissions of Substances that Impact the Environment

Recognition of Issues and Basic Approach

Mankind has taken significant strides forward thanks to technological progress. Its immense contribution includes dramatically lower mortality rates and higher standards of living. On the other hand, the negative aspects that have accompanied this progress cannot be ignored. It has increased pollutants and greenhouse gas emissions, causing environmental problems. In response, the Mitsubishi Chemical Holdings Group has endeavored to conduct corporate activities in consideration of the environment while contributing to technological development through its businesses.

Main Activities

Reducing Emissions of Substances that Impact the Environment From Business Activities

The Mitsubishi Chemical Holdings Group has identified substances that impact the environment in connection with its business activities. These are greenhouse gases (GHG), which contribute to global warming; nitrogen oxides (NOx) and sulfur oxides (SOx); particulates; volatile organic compounds (VOCs); and nitrogen in discharged water. The Group has been conducting activities to reduce these emissions based on emissions-reduction targets.

Disclosing Environmental Information

Mindful of the importance of verifying and reporting on corporate activities from a global perspective in disclosure related to the environment, the Mitsubishi Chemical Holdings Group has disclosed information in the KAITEKI Report and on its corporate website. The Group will further enhance the reliability of its disclosure by steadily extending it to include more organizations covered, increase disclosure elements, and heighten their precision.

Targets and Results

Target Reduce environmental impact by 30% from fiscal 2005 levels (Target: fiscal 2015)
Result Fiscal 2013 33% reduction (From fiscal 2005 levels)

Among substances that are recognized as having an environmental impact, Mitsubishi Chemical Holdings Group targets the following six substances: GHG (Greenhouse Gases), NOx (Nitrogen Oxides), SOx (Sulfur Oxide), particulates, VOC (Volatile Organic Compounds) and total nitrogen in discharged water. The Company quantifies to what extent these substances have impacts on the environment by using an index based on an environmental impact assessment methodology.

Mitsubishi Plastics, Inc.: Entry into the engine exhaust NOx gas catalyst market with an SCR catalyst using the high-performance zeolite AQSOA

Under the increasingly stringent automotive and truck exhaust regulations anticipated in Western countries and Japan, Selective Catalytic Reduction (SCR) systems are attracting interest for their ability to reduce and convert the nitrogen oxides (NOx) contained in exhaust gas into nitrogen and water with the aid of Diesel Exhaust Fluid (DEF) or AdBlue. Mitsubishi Plastics, Inc. has been pushing ahead with research and development into zeolite catalysts (SCR catalysts) for the SCR system using the original high-performance zeolite* AQSOA. These development efforts resulted in a success, realizing an SCR catalyst that delivers superior catalytic performance across a wide range of temperature including low temperature ranges around 200℃. The SCR catalyst also achieves high durability even under a high-temperature environment that is essential for SCR catalysts, along with outstanding cost effectiveness. Mitsubishi Plastics, Inc. is currently working to establish global production and supply systems for the high-performance zeolite AQSOA for use in SCR catalysts.
