According to the royal initiative of His Majesty King Bhumibol Adulyadej the Great, His Majesty King Bhumibol bestowed royal property to build The First Royal Factory in 1972. It was responsible for processing agricultural products to assist farmers and raise the living standards of villagers in the Mae Ngon and Doi Ang Khang river basins. It served as a model in solving social, economic and environmental problems comprehensively and sustainably.
"Doi Kham", therefore, began to operate social enterprises in the form of “Social Entreprise” without expecting maximum profit, from the first day of the establishment of the First Royal Factory until now. It is consistently developing and extending benefits to safeguard stakeholders, both people and the environment. It also aims to enhance the area of The First Royal Factory at Fang, The Second Royal Factory at Mae Chan, The Third Royal Factory at Tao Ngoi, The Fourth Royal Factory at Lahan Sai and Doi Kham Food Products Company Limited. Through their website, Doi Kham aims to strengthen education, agricultural industry, environmental conservation and cultural traditions by being one of their platforms for gathering knowledge, learning and exchanging experiences continuously with those interested.
