Efficacy of Energy Saving Project in Niigata Mill, Hokuetsu Kishu Paper Co., Ltd.

Abstract

Recent years, the global warming is the one of the biggest issue for us. Especially, reducing carbon dioxide emissions which are well known as a greenhouse gas is our main concern. Because of these movements, we need to expedite both the reducing fossil fuel consumption and the saving other energy consumptions at the same time. In order to approach these issues, we have started the energy saving program at Niigata mill since 1980’ s and these works have brought great success. However, after we installed the new paper making machine PM 9 and converted the other related processes such as the pulping, the bleaching and the chemical recovery facilities, the energy consumption surged and that cost put pressure on our profit.
In this report, we introduce the energy saving program at the Niigata mill and give the detail of our achievements after we installed and converted the new processes.
