Sumitomo Chemical’s business began when gasses from the copper smelting process of the Besshi Copper Mine caused a pollution problem, and there was an urgent need for a solution. Sumitomo Chemical was founded to resolve this problem, which it did by extracting sulfur (sulfur dioxide gas) from copper ore to use as the raw material for sulfuric acid and fertilizer manufacturing in an effort to overcome an environmental problem while also improving agricultural productivity. This philosophy of resolving problems facing society through its business is in the DNA of the Sumitomo Chemical Group.
Sumitomo Chemical's Corporate Philosophy is based on Sumitomo's Business Principles and is composed of the Business Philosophy, which integrates the company's business principles, mission and values; Basic Principles for Promoting Sustainability, which integrates its concepts regarding and commitment to sustainability promotion; and the Sumitomo Chemical Charter for Business Conduct, which lays out the code of behavior serving as the basis for the Company's compliance system.
