Thailand, one of the leading industrialized countries in Southeast Asia, has been tackling with various environmental pollution issues emerging along with economic growth. Emissions from industrial facilities and exhaust gas from mobile sources has been causing air pollution in large cities and industrial parks. Chao Phraya River, canals and waterways in urban areas has been deteriorated due to urbanization and economic activities. Social interests on management of increasing wastes, including municipal wastes, industrial wastes, waste electrical and electronic equipments, infectious wastes, as well as noise and odor issues has been risen.

Although many projects have been reopened lately, this Map Ta Phut pollution issue once again highlighted the importance and risks of environmental management in Thailand.
