Mitr Phol

Mitr Phol sugar business was established as a small family business in Ban Pong district, Ratchaburi province, producing and trading condensed syrup to sugar mills in 1946. In 1956, the company began to produce its own sugar. In 1983, Mitr Phu Kieo Sugar Mill was constructed in Phu Khiao district, Chaiyaphum province, with a sugarcane processing capacity of 27,000 tonnes per day. In 1990, Mitr Phol Sugar Mill in Suphan Buri province was established with a processing capacity of 45,500 tonnes per day. The company expanded its business internationally in 1993 to Guangxi province, China with four mills. Mitr Phol owns seven sugar mills in Guangxi and with an annual capacity of approximately 10 million tonnes of cane, or approximately 1.3 million tonnes of sugar per year. In 1994, Mitr Phol Sugar Mill (Suphanburi province) was the first mill in Thailand certified by ISO 9002 and has been recognized with a National Certificate of Excellence and Global Standards. In 1995, Mitr Phol took over a sugar company in Phu Wiang district, Khon Kaen province and named it Mitr Phol Phu Wiang Sugar Mill. In 1997, Mitr Phol constructed a sugar mill in Hai Tung County, China. Later in the same year, Mitr Kalasin Sugar Mill was established, in Kuchinarai district, Kalasin province, with a processing capacity of 23,000 tonnes per day. In 2006, Mitr Phol broadened its production to Savannakhet province, Laos and established Mitr Lao Sugar Co., Ltd. to develop sugarcane farming with advanced production technology to export to the European Union. Mitr Phol further expanded its investments to Queensland, Australia.

In 2020, the company was filed a class action lawsuit due to alleged violent eviction allegations in Cambodia in 2008–09, the first transboundary lawsuit of its kind in Southeast Asia.

Following the legal proceedings initiated in 2018 by the plaintiff against Mitr Phol, after the court mediation process, both parties were afforded the opportunity to present their perspectives, thereby enhancing mutual understanding and facilitating a more comprehensive recognition of each other’s viewpoints.

In February 2025, Mitr Phol reached a landmark settlement with the families and agreed to pay a "substantial, though undisclosed" sum to their communities. This was paid in May of that year. The case has now been dismissed.
