Industrial estate development is a business that can directly cause negative environmental impact if operating without good management. The Company, therefore, places importance on the environmental impact management as it is one of the Company’s material topics.


Inefficient management of negative environmental impact directly affect the quality of ecosystem and the quality of life of people working in the industrial estates and living in surrounding communities. This will destroy trust of all stakeholders and lead to losing social license to operate for future expansion. In the worst case, the Company’ business licenses can be revoked.


The efforts to manage and control the environmental quality in large industrial estates enables 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 the level of stakeholder trust in the Company’s operation and the satisfaction of those customers who place importance on such matter. Additionally, the Company can contribute the knowledge of the environmental management to the society and the country in which it is operating.
The Company has assessed the risks and impacts from business activities throughout the supply chain and keeps overseeing the activities of factory operators in both AMATA Industrial Estates that may cause a negative impact on the Company's stakeholders. The environmental risk assessment shows that the concerned environmental impacts are air pollution, waste, and water pollution. Therefore, the Company focuses on good and efficient pollution management by using appropriate technologies and strictly complying with the laws prescribed under the Environmental Laws related to business operations in the industrial estates, measures from EIA report, and environmental standards

Implementation according to measures specified in the EIA report

The Company, in collaboration with the Industrial Estate Authority of Thailand (IEAT), oversees and monitors both AMATA’s industrial estates to ensure that their operations and policies comply with the laws, rules and regulations and minimize negative impacts on society and the environment. The Company adhere to the measures specified in the EIA report regarding the prevention, correction, and monitoring of environmental impact in the industrial estates to build community trust in the industrial estate’s environmental management and to promote environmental management guidelines of the industrial estates based on environmental governance principles. The measures are as follows:

1. Environmental Monitoring and Control Center: EMCC

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. (Disclosure 305-7)
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. (Disclosure 305-7)
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.

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

The Company discloses the environmental 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), Industrial Estate Authority of Thailand (IEAT), Regional Environment Office 13 (Chonburi), and Provincial Offices of Natural Resources and Environment every 6 months.  The report discloses the performance after the implementation of preventive and corrective measures stated in the Environmental Impact Assessment report in both AMATA City Chonburi and Rayong Industrial Estate.  The Company also presents the EIA Monitoring reports every 6 months to the Environmental Quality Audit Committee of both industrial estates, which consists of the Industrial Estate Authority of Thailand (I-EA-T), AMATA environmental officers, local government representatives, local community representatives, and representatives from manufacturing operators in AMATA Industrial Estate, for their acknowledgement.

In 2021 the Company had presented the results of the EIA Monitoring Report to the Environmental Quality Audit Committee of both industrial estates in four meetings with an objective to allow the Committee 1. to provide opinions and suggestions on the environmental management of the industrial estate, environmental impacts caused by the industrial estate and complaints concerning 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 the 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 environmental impact caused by the Company’s operation.  However, there were some suggestions for the Company to increase the efficiency in the operation management of both industrial estates:

Suggestions from the
Environmental Quality Audit Committees

AMATA City Chonburi

  • Request for knowledge and understanding in the wastewater treatment to people in the communities to jointly help mitigate community wastewater problem which may affect the quality of surface water.  For instance, Nong Mai Daeng Community Pilot Project regarding sustainable wastewater and refuse management should be expanded to other communities around AMATA industrial estates.

  • Request for the traffic problem solving especially at the connecting areas between industrial estate and community to enhance the efficient traffic draining.  The committee also suggests an application be used to monitor incidents occurred within the industrial estate, traffic and accidents in particular, in conjunction with CCTV as Smart Safety industrial city.
