Established on 7 May 1945 by Mr.Suree Asdathorn, Thai Roong Ruang Sugar Group is Thailand ‘s first private sugar factory, commencing its early operation since post-World War second. At that time, Thailand had suffered a severe crisis of sugar shortage. So the government supported a policy to encourage private sector to establish the sugar cane factory. However, the cost to secure the production machinery was too high since it relied on overseas import. Mr. Suree Asdathorn or better known as “Thoukae Lin” who was then an expert on mechanics had applied his skills in mechanism of iron-lathing to produce and assemble various components of locally unavailable and costly sugar producing machines. His production did not rely on any imported machinery components, and this enabled continuous operations, which result in a great success.
