Epson and the Environment


Example: Slashing Acetone Use

Epson's Suwa Minami Plant, which produces liquid crystal display panels, uses acetone, a volatile organic compound, in the washing process (to keep contaminants out liquid crystals are injected into the panel). Members of the "Sukkiri Circle" kaizen team looked for ways to reduce acetone use. Rather than sticking to conventional ways, they rethought the washing process and materials used, vastly increasing quality and reducing the number of washing cycles. As a result, the plant was able to use just one-tenth the amount of acetone it did in FY2011. With 90% less waste liquid and containers for it after using the acetone, this has helped greatly reduce our environmental footprint.
