The History of Siam Tree Development
Siam Tree Development Co. Ltd. is founded on 1990 with an objective to research and develop wood barks, purchase, process, and distribute high-quality wood chips to the international market, to be manufactured into high quality paper pulps. Later, we discovered the significance that the soil contributes in growing a healthy tree so we expand our business to cover products that increases soil quality such as: organic fertilizers, soil conditioners, nursery materials etc. We aim to create a satisfactory standard for our products, by manufacturing high quality products for the future paper pulp industry. We also seek to expand our client base to cover the entire agricultural households, the largest demographic in Thailand. We aspire to be the force that nurtures agriculture in Thailand, for the agricultural industry to flourish with a sustainable growth.
