About Us

A Square Power Trade Co., Ltd. is a Thailand registered company. It was established in 2012 by a group of young experts specializing in different areas including manufacturing, chemicals, agricultural, medical, health and IT business. Our belief is primarily based upon the fact that the business growth, the socio-economic development and the environmental sustainability are interrelated. Hence for us, the company is not only an instrument for generating profit, but it is also a vehicle for accomplishing the long-term development of the society as well as the conservation of the environment. From this belief, the Green Business concept was defined and developed taking economic, social and environmental dimensions into account and it has laid a strategic intent on what the company is striving for.
