Epson and the Environment

Production

Epson has manufacturing sites and sales centers in all parts of the world making environmentally-conscious transportation an important consideration. Here we present examples of such environmentally-conscious transportation initiatives in which we introduced high cube containers1 and changed our shipping method.

Topic 1 : Improving Transport Efficiency with High Cube Containers

Currently, high cube containers account for about 70% of shipping containers in the marketplace. Hitherto, Epson has used the standard type of container for shipping products from its factories, but with the widespread adoption of high cube containers, we are gradually making the switch.
Since the inner dimensions of the containers are higher, palletizing products for standard containers resulted in wasted space amounting to about 10%. Optimizing the pallets for high cube containers reduces the number of containers required, contributing to reducing environmental impact by raising transportation efficiency.

Says Koyuru Naito of Epson's Logistics Planning Department who led the initiative, "All of our arrangements including the number of products shipped and the height of the pallet racks in our warehouses were optimized for pallet sizes to fit standard containers. In order to introduce high cube containers, it was necessary to ask for the cooperation of the warehouse managers at sales companies who receive the containers. We had to ask them to review the layout of their warehouses, optimize the method of stacking and so on. We had a very hard time adjusting the cost factors, but a shared awareness that this would reduce our environmental impact was a very important point in undertaking this activity."

For shipments from Southeast Asia, where many of Epson's finished products are manufactured, the switch to high cube containers for all areas of Europe was completed in fiscal 2011 and in fiscal 2015 for the U.S., Brazil and India.

Results of Switching Containers for Shipping to the U.S.

*We have calculated the reductions in CO2 emissions emitted when transporting containers by cargo ship, train and truck from our manufacturing affiliates in Southeast Asia, as a result of reducing the number of containers shipped to the U.S. by about 200. The unit indicator by the Japan Ship Technology Research Association is used for calculating emissions during sea transport.

Topic 2 : Reduced Environmental Impact by Changing Printhead Shipping

Previously, printheads for shipping to our printer manufacturing sites in Indonesia were gathered from our plants around Japan at Tohoku Epson in Yamagata Prefecture and transported by truck to Narita Airport for air transportation. By establishing a sea transportation pipeline from Sakata Port, which is located conveniently about 8 km from Tohoku Epson, we significantly reduced our costs and CO2 emissions.

*We calculated the CO2 emissions from shipping a 20-foot container from Tohoku Epson to Indonesia's capital, Jakarta. The unit indicator by the Japan Ship Technology Research Association is used for calculating emissions during sea transport.
