Our vision

We commit to complying with regulations on environmental protection and labor safety, while also striving to research and apply new technologies to minimize the impact of production activities on the environment. We aim to contribute to the sustainable development of the community and society.With the increasing severity of global climate change, countries worldwide have recognized the importance of energy conservation, carbon reduction, and protecting the planet. Vietnam, as a developing country, has also joined this environmental consensus. In response to international environmental requirements, the Government of Vietnam passed strict environmental, fire safety, and commercial regulations on December 16, 2020. These regulations require factories that use polluting fuels to switch to clean energy fuels such as electricity, natural gas, and liquefied petroleum gas to promote pollution-free industries by July 1, 2021.
