Preventing Global Warming
Insulation cover for drying-furnace

Global warming prevention requires a reduction not only in CO2-producing energy consumption, but also in emissions of other greenhouse gases.
Alps Electric has established a target to reduce CO2 emissions per unit of output in fiscal 2010 by 15% of fiscal 2004 levels. To achieve this, we have replaced some production equipment with energy saving models, and conduct regular “energy patrols,” which also heighten awareness about saving energy. We had aimed to discontinue using PFCs and HFCs (*A) in the production process by the end of fiscal 2010, but had already achieved this objective by June 2006.
(*A) PFC/HFC: Perfluorocarbon (PFC): This
chemical is used in the etching process for semiconductors and
other purposes. Although the quantity of PFC used is small, its
greenhouse effect is very potent.
Hydrofluorocarbon (HFC): An alternative to chlorofluorocarbon.

We discontinued generating our own power which was inefficient, and began to buy power. We expect to reduce energy-related CO2 emissions by 3,000 tons a year. In addition, we eliminated the use of PFCs in the production process by switching to water solvents.

We conduct “energy patrols” on non-operating days every second month. During these patrols, we examine whether any equipment still consumes power whilst not in operation or in standby mode. We also check for any air leakages that may be wasting power. These patrols aim to eliminate waste and to raise awareness about energy saving.

We use insulation covers for drying-furnaces in order to reduce heat emissions, therefore reducing the load on the air-conditioning system. In fiscal 2006, we used insulation covers on a limited number of drying-furnaces on a trial basis, but now plan to use covers for the other drying-furnaces too.
