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.
