Environmental Quality Control 


Industrial estate development is a business that causes environmental pollution, which can directly affect the quality of the environment in the area and the health and quality of life of stakeholders working in industrial estates and communities around them. Inadequate environmental quality management may cause the stakeholders to lose trust; the local community may oppose future business expansion, and the Company’s business license may be revoked. 


The efforts to manage and control the environmental quality in large industrial estates enable the Company to develop new products and services by adopting modern and efficient innovation and technology to ensure that the environment will be closely monitored, thereby increasing stakeholder trust in the Company’s operation and the satisfaction of those customers who place importance on such matters. Additionally, the Company can contribute its knowledge of environmental management to the society and the country in which it is operating.

Management Approach

The Company has assessed environmental risks and impacts arising from its operations throughout the supply chain and monitored the suppliers’ and contractors’ operations, as well as the operations of the factories in both AMATA industrial estates, that may cause negative environmental impacts. According to the assessment, environmental pollution that had a significant impact on stakeholders includes air pollution, industrial and solid waste, water pollution, factory noise, and odor. As a result, the Company concentrated on environmental impacts monitoring and control to be within the criteria required by law or better by choosing appropriate and efficient technology and adhering to the laws related to business operations in industrial estates, measures specified in the EIA report, and various environmental standards. 

The Company, in collaboration with the Industrial Estate Authority of Thailand (IEAT), supervises and monitors both AMATA's industrial estates to ensure compliance with laws and regulations, and minimize negative impacts on society and the environment. The Company follows the measures specified in the EIA report to prevent, correct, and monitor environmental impact in the industrial estates, building community trust in environmental management, and promoting guidelines based on environmental governance principles. The results of these efforts are as follows: 

Implementation according to measures specified in the EIA report

1. Environmental Monitoring and Control Center: EMCC

The Environmental Monitoring and Control Center (EMCC) was established in 2013 and has been operating to continuously monitor the environmental quality in both AMATA industrial estates. The Environmental Monitoring and Control Center is made up of 5 systems and displays the online real-time environmental quality data from both industrial estates on a 24-hour basis, as shown in the diagram below. 

1) The central industrial estate database system

is working as an information center by collecting environmental data from the entire industrial estates and the factories operating in the industrial estates, such as water consumption, wastewater volume, wastewater quality, industrial waste volume and air quality, etc.

2) The monitoring and controlling system
of the effluent quality after being treated in the central wastewater treatment plant monitors BOD values and online linked to EMCC. If the BOD online shows that the effluent quality exceeds the standards as specified in the Notification of the Ministry of Natural Resources and Environment regarding standards for wastewater quality from industrial plants, industrial estates and industrial zones dated 29 March 2016 and the Notification of Ministry of Industry regarding Industrial Effluent Standards B.E. 2560 dated 30 May 2017, the EMCC will notify the central wastewater control center to analyze, identify the causes and solve the problems immediately.
3) The Air Quality Monitoring Station (AQMS) is an air quality monitoring system.

There are four AQMS at the AMATA City Chonburi Industrial Estate area covering the surrounding community areas of U Tapao Temple, Mab Sam Kleow Temple, Panthong Ratchanupatham School and Omkaew Temple. There are two AQMS at AMATA City Rayong Industrial Estate covering the surrounding community areas of Health Promotion Hospital, Tumbon Mabyangporn and Pananikom Temple. The AQMSs measure air pollutants which are the total suspended particulates (TSP), particulate matter up to 10 microns (PM10), particulate matter up to 2.5 microns (PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), and wind speed/ wind direction. The AQMSs also measure wind speed and direction to analyze the trend of pollution spreading and the source of any air pollution. The AQMSs also continuously measure the rainfall and temperature to precisely predict the precipitation and lowest-highest temperature in the area to assess the local climate for environmental management planning. 

4) The monitoring and controlling system of air quality emitted from factory smokestacks.

This online system monitors and controls environmental quality by linking the emission inventory of each factory and Continuous Emission Monitoring System (CEMS) to I-EA-T’s EMCC. If the factory is found that its air emission quality exceeds the standards, the EMCC will notify the factory to inspect, report the causes, and immediately make corrections and improvement. 

5) The security and environmental surveillance by Close Circuit Television (CCTV) system
to process information used for safety planning, traffic management and environmental monitoring within the AMATA industrial estates.

Continuous monitoring of environmental quality at EMCC instills confidence in stakeholders that the Company places importance
on environmental impact management and earnestly monitors environmental quality, so that the environmental problems in the AMATA industrial estates will be promptly responded to and resolved. All environmental quality data in AMATA industrial estates is linked to the Environmental Monitoring and Control Center (EMCC) of the Industrial Estate Authority of Thailand.

In 2022, the Company and factories in both AMATA industrial estates had no environmental laws or regulations in violation, and the measured environmental quality indicators, such as air quality and wastewater quality after treatment from the central wastewater treatment system, were all within the legal standards.

2. Disclosure of the actions and performance according to Preventive & Corrective Measures for Environmental Impacts (EIA Monitoring Report)

The Company discloses its actions and performance according to the environmental impact preventive and corrective measures in the Environmental Impact Assessment (EIA) Monitoring Report, which is submitted to the Office of National Resources and Environmental Policy Planning (ONEP), the Industrial Estate Authority of Thailand (IEAT), Office of Environmental and Pollution Control 13 (Chonburi), and the Provincial Office of Natural Resources and Environment every six months. The report discloses the performance after the implementation of preventive and corrective measures stated in the EIA Monitoring Report in both AMATA City Chonburi Industrial Estate and Rayong. The Company also presents the EIA Monitoring reports every six months to the Environmental Quality Audit Committee of both industrial estates, which consists of the Industrial Estate Authority of Thailand (IEAT), AMATA environmental officers, local government representatives, local community representatives, and representatives from the factories in AMATA Industrial Estate.  

In 2022, the Company presented the results of the EIA Monitoring Report to the Environmental Quality Audit Committee of both industrial estates in four meetings with the objective of allowing the committee; 1) to provide opinions and suggestions on the operations related to the environment of industrial estates and the impacts of industrial estates on the environment, 2) to acknowledge the results of the environmental quality monitoring within and outside the industrial estates, and 3) to help distribute correct knowledge and understanding of environmental management and to build community trust in industrial estate management.  The Environmental Quality Audit Committee of both industrial estates did not have any suggestions concerning the environmental impact caused by the Company’s operations. However, there were some suggestions for the Company to increase the efficiency of the operations management of both industrial estates: 

Suggestions from the
Environmental Quality Audit Committees

AMATA City Chonburi

  • Request for knowledge and understanding about wastewater treatment to the people in the communities to jointly mitigate community wastewater problems that may affect the quality of surface water. For example, the Nong Mai Daeng Community Pilot Project, which focuses on sustainable wastewater and community waste management, should be expanded to other communities around the AMATA industrial estate, such as the Klong Tamru community and other communities in the future. 

  • Request for assistance in solving traffic problems, especially at the connecting areas between the industrial estate and the surrounding community, to improve traffic flow efficiency. Increase the number of security personnel to facilitate convenience during rush hours, and police officers, especially at the connecting points between the industrial estate and the community, schools, etc. Also, propose the use of an application to monitor incidents that occur within the industrial estate, in conjunction with CCTV, especially regarding traffic and accidents, to promote the development of the industrial city in terms of Smart Safety. Additionally, expand the outcomes of the Safety Road project of AMATA Industrial Estate to other industrial estates.

  • Request AMATA to expand the Farm to Factory project to other communities so that their local products can reach buyers or consumers in the factories, to help support and promote this project to factories in the industrial estates in order to expand new markets and marketing channels through factory kitchens or factory markets. This will help drive the local community's economy by support from the factories in the industrial estate. 

  • Request AMATA to help support and expand the Eco School project to other schools near the industrial estates. This will provide knowledge and understanding on environmental protection and safety to the youth and the community, as well as encourage their participation with the factories through the Eco Community project of the Industrial Estate Authority of Thailand (IEAT). 

  • Request for healthcare service expansion at Vibharam Amata Nakorn Hospital to provide comprehensive treatment coverage to social security health service recipients. Currently, those who use social security health benefits have to wait a long time to receive medical treatment at the hospital. 

AMATA City Rayong

  • Request for training activities to educate operators in the industrial estates, particularly foreign operators, on environmental laws and safety measures for business operations within the industrial estate. This is to minimize the possibility of causing environmental problems from the factory, such as air pollution, odors, water pollution, and noise pollution, which may negatively affect the community.
  • Request for a solution to traffic problems during rush hour, opening up the connecting areas between the industrial estate and the community to enhance efficient traffic flow and facilitate traffic for the community, and networking with the police to strictly enforce traffic discipline.

  • Request for support and assistance for people infected with COVID-19, especially in educational and community areas surrounding the industrial estate.  

Implementation according to the government policy

1. Eco-Industrial Town Development

The Company has collaborated with the Industrial Estate Authority of Thailand (IEAT) in developing AMATA industrial estates as Eco-industrial Towns according to government policy.

The guidelines for a development plan are in line with the development framework laid out by the IEAT, which consists of 5 dimensions and 22 aspects. The five dimensions, which are physical, economic, environmental, social, and management, are related to the Company’s stakeholders: local communities, customers, employees, factory employees, and local government authorities. There are three levels of eco-industrial town development, namely Eco-Champion, Eco-Excellence, and Eco-World Class. The Company has targeted upgrading its two AMATA industrial estates to achieve Eco-World Class levels in 2025.
