Thailand urges factory operators to tackle PM2.5 air pollution

Department of Industrial Works (DIW), Ministry of Industry of Thailand published a document titled “Request for a strict implementation of production planning and control of air pollutants emissions from business operations” dated 8 November 2021. After the rainy season, from November to February of the next year, Thailand is commonly in the critical situation of dust (PM 2.5) nationwide. The 24-hours average concentration frequently exceeds the standard, which can cause a health risk. The document was prepared to request cooperation from industries to combat and reduce air pollution in the Kingdom.


In the notification, DIW requests factory entrepreneurs to carry out the following:

  1. Production planning and supervision of business operations to control air pollution within the standard, always maintain an efficient air pollution treatment system, and strictly comply with the Factory Act B.E. 2535 (1992), especially the requirements regarding environmental personnel of the factory, and reporting of the air pollution emission results (Ror Wor.) via electronic systems of DIW.
  2. Supervise boilers or boilers that use liquid as a heat medium to be effective and complete combustion, as well as implement safety and environmental measures.
  3. In the case of the existing continuous emission monitoring system (CEMS), send information to the Industrial Environment Monitoring Center of DIW.
  4. Provide information to DIW according to the industrial pollution emission report form as in attachment 2 or via Google form by 19th November 2021.
