Summary of the environmental and social initiatives implemented at the Ohtsu Plant.
1. Environmental Initiatives
|Use of highly efficient equipment at the Ohtsu Plant||
Reducing CO2 Emissions
Since fiscal year 2003, the Ohtsu Plant has made systematic progress on changing the hydraulic power units for processing machine to models which conserve more space and energy. For each unit replaced, CO2 emissions have decrease by three tons annually. Through September 30, 2009, eighty-six units had been replaced as part of an ongoing upgrade program. In addition, the plant installed inverter conversions for heating, ventilation, and air-conditioning and production equipment, and switched over to large-capacity motors and high-efficiency lighting fixtures.
