Decisive polices

"The user's consciousness is very important. Let alone equipment investment, management and supervision of energy consumption can save considerable amount of costs", Mr Nguyen Quoc Toan, Head of the company's electrical department stresses.

With that thought, the first thing the company implements for energy saving is formulating regulations and policies to encourage workers to save and use electricity efficiently. Accordingly, every day at each production workshop the company is disseminating information about saving energy.
