Laws & Regulations

National Laws and Regulation

Although Thailand has conducted several efforts to manage plastic waste, most remain voluntary actions with limited legal measures (Wichai‑utcha and Chavalparit, 2019). However, several legal frameworks listed below support the effort:

  1. Enhancement and Conservation of National Environmental Quality Act B.E. 2535 (1992)  is the fundamental environmental law that governs the planning for environmental management, monitoring environmental quality, and establishing the system for environmental impact assessment (Siriratpiriya, 2014)[1]. Section 23(1) of the Act cites grants to a government agency or local administration for investment in and operation of a central waste disposal facility, including the acquisition and procurement of land, materials, equipment, instruments, tools, and appliances necessary for the operation and maintenance of such facility. Section 80 requires waste disposal facility owners or possessors to submit a report summarising the functioning results of the facility.

  2. Public Health Act B.E. 2535 (1992) provides local governments with the power and duty to prescribe rules, procedures, and measures to manage and maintain the collection, transportation, and disposal of sewage and solid waste with provisions of the ministerial regulation (Section 20). Section 7 states that local governments may issue or amend local provisions and prescribe details of operation in their localities.

  3. Factory Act, B.E. 2535 (1992) regulates the establishment, operation, and control of factories in Thailand to prevent and mitigate environmental pollution and health impacts arising from industrial activities. With respect to plastic waste management, the Act governs the handling, treatment, recycling, and disposal of plastic waste generated from industrial processes. It empowers the Department of Industrial Works to set standards and requirements for waste storage, transportation, treatment, and disposal, including plastic and hazardous industrial waste. The Act also requires factories to implement appropriate pollution control measures and comply with environmental and safety regulations, thereby supporting the reduction of plastic waste impacts on the environment and public health.

  4. Act on the Maintenance of the Cleanliness and Orderliness of the Country B.E. 2535 (1992) regulates the prohibition on waste littering, including cars littering on roads (Section 13), places where grass or trees grow (Section 26), and littering on waterways and other public spaces (Section 31–33). As amended on 16 January 2017, the Act outlines the authority of local administration organisations to collect and manage waste under supervision of the provinces and the Ministry of Interior.

  5. National Health Act B.E. 2550 (2007), especially Section 5, cites the right of every individual to live in a healthy environment and the duty to cooperate with state agencies (including national, provincial, and local governments) to create such an environment.

  6. Constitution of the Kingdom of Thailand B.E. 2560 (2017), especially Section 58 declares that the State shall undertake an environmental quality and health assessment and shall arrange a public hearing in advance in order to let them consider before the actual implementation or granting of permission as provided by the law.

  7. Notification of the Ministry of Public Health No. 435 on prescribing quality or standard of and label for plastic packaging under the Food Act, B.E. 2522 (1979) set the quality and standard in plastic food packaging by increasing the efficiency of consumer safety protection and promoting the sustainable use of plastics according to the concept of circular economy.

  8. Notification of the Pollution Control Department B.E. 2565 (2022) on the characteristics of plastic scrap suitable for recycling defines the characteristics of plastic scrap suitable for recycling. This promotes circular economy and may be used as a guideline for plastic waste segregation by individuals, households, junkshops, and local government organisations.

  9. Draft Sustainable Packaging Management Act is a draft act that establishes an Extended Producer Responsibility (EPR) framework in Thailand. It was proposed by the Thai Ministry of Natural Resources and Environment in March 2024 and is currently under development as of 2026. The Act is expected to be submitted for enactment within the timeframe of the National Solid Waste Management Plan (2022–2027). Key aspects in the draft act include:

    -EPR Obligation: Producers must ensure the recovery and recycling of packaging waste, delegating responsibility to certified Producer Responsibility Organisations (PROs).

    -Single-Use Packaging Bans: The Act would allow the formation of a committee to ban certain single-use packaging across Thailand.

    -Timeline and Implementation: A 3-year timeline is set for developing EPR infrastructure, including a digital registration system, aligning with Thailand’s Action Plan on Plastic Waste Management (2023-2027).
