Environmental Quality Control 


Industrial estate development is a business activity that can lead to environmental pollution, directly impacting the quality of the environment in the area and the health and well-being of stakeholders working in these industrial estates and neighboring communities. Insufficient management of environmental quality may result in stakeholders losing trust. This, in turn, could provoke opposition from the local community to future business expansions and potentially lead to the revocation of the Company’s business license.


The Company's efforts to manage and control environmental quality in large industrial estates facilitate the development of new products and services. By embracing modern and efficient innovation and technology, the Company ensures close monitoring of the environment. This enhances stakeholder trust in the Company's operations and satisfies customers who prioritize environmental concerns. Moreover, the Company can share its expertise in environmental management with the society and country where it operates.

Management Approach

The Company has conducted an assessment of the environmental risks and impacts associated with its operations throughout the supply chain. It has also monitored the activities of suppliers, contractors, and factories within both AMATA industrial estates that could potentially lead to adverse environmental effects. Based on this assessment, significant environmental issues affecting stakeholders include air pollution, industrial and solid waste, water pollution, factory noise, and odors. Consequently, the Company has prioritized the monitoring and control of these environmental impacts to meet or exceed legal requirements. This involves selecting appropriate and efficient technologies, complying with relevant laws governing business operations in industrial estates, adhering to measures outlined in the Environmental Impact Assessment (EIA) report, and following various environmental standards.

The Company collaborates with the Industrial Estate Authority of Thailand (IEAT) to supervise and monitor both AMATA's industrial estates, ensuring compliance with laws and regulations while minimizing negative impacts on society and the environment. It adheres to the measures outlined in the Environmental Impact Assessment (EIA) report to prevent, correct, and monitor environmental impacts within the industrial estates. These efforts aim to build community trust in environmental management and promote guidelines based on environmental governance principles. The results of these endeavors are as follows:

Implementation according to measures specified in the EIA report

1. Environmental Monitoring and Control Center: EMCC

The Company acknowledges the environmental impacts caused by factories located in AMATA Industrial Estates, which are beyond the Company's direct control. Therefore, the Company has established the Environmental Monitoring and Control Center (EMCC) since 2013 to continuous monitor environmental quality in both AMATA industrial estates aiming to ensure that environmental quality indicators such as air pollution and wastewater, meet legal standards. The EMCC integrates environmental quality data from both industrial estates, consisting of five systems, and displays real-time environmental quality data online 24/7, as shown in the diagram below.

1) The central industrial estate database system

serves as an information center, gathering environmental data from across the entire industrial estates and the factories operating within them. This includes data on water consumption, wastewater volume, wastewater quality, industrial waste volume, air quality, and more.

2) The monitoring and controlling system of the effluent quality

after being treated in the central wastewater treatment plant, monitors parameters such as BOD and COD values and is linked online to the EMCC. If the system indicates that the effluent quality exceeds the standards outlined in the notifications issued by the Ministry of Natural Resources and Environment regarding standards for wastewater quality from industrial plants, industrial estates, and industrial zones dated March 29, 2016, and the notification of the Ministry of Industry regarding industrial effluent standards B.E. 2560 dated May 30, 2017, the EMCC will notify the central wastewater control center to analyze, identify the causes, and implement immediate solutions.

3) Air Quality Monitoring Station (AQMS)

is a continuous air quality monitoring system covering the surrounding There are four AQMS stations located around AMATA City Chonburi Industrial Estate area covering community areas of U Ta Pao Temple, Mab Sam Kleow Temple, Panthong Ratchanupatham School, and Om Kaew Temple. Also, there are two AQMS stations in the surrounding area of AMATA City Rayong Industrial Estate covering community areas of Mapyangphon Health Promoting Hospital, and Pananikom Temple. The AQMS measures various air pollutants, including total suspended particulates (TSP), particulate matter up to 10 microns (PM10), particulate matter up to 2.5 microns (PM 2.5), sulfur dioxide (SO2), and nitrogen dioxide (NO2), as well as wind speed and direction. These measurements help analyze the trend of pollution spreading and identify the sources of air pollution. Moreover, the AQMS continuously monitors rainfall and temperature to accurately predict precipitation and assess the local climate for environmental management planning.

4) The monitoring and control system for air quality emitted from factory smokestacks

is in place. Even though the Company itself does not engage in activities directly emitting air pollutants, nor does it possess the authority to regulate factory emissions, it places significant emphasis on monitoring and controlling environmental quality by integrating the emission inventory of each factory and the Continuous Emission Monitoring System (CEMS) with the industrial estate's comprehensive air quality measurement database (Emission Inventory). This integrated approach aims to manage air quality within the industrial estate area (Emission Loading). If a factory's air emission quality exceeds the standards, the Environmental Monitoring and Control Center (EMCC) will promptly notify the factory to conduct inspections, report the causes, and implement immediate corrective measures and improvements.

5) The security and environmental surveillance provided by the Closed Circuit Television (CCTV) system

processes information used for safety planning, traffic management, and environmental monitoring within the AMATA industrial estates.

Continuous monitoring of environmental quality at the Environmental Monitoring and Control Center (EMCC) instills confidence in stakeholders that the Company prioritizes environmental impact management and diligently monitors environmental quality. This ensures that environmental issues within the AMATA industrial estates are promptly addressed and resolved. All environmental quality data in the AMATA industrial estates are linked to EMCC of the Industrial Estate Authority of Thailand.

In 2023, neither the Company nor the factories in both AMATA industrial estates violated any environmental laws or regulations. Environmental quality indicators, such as air quality and wastewater quality following treatment from the central wastewater treatment system, all met 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 every six months to the Office of National Resources and Environmental Policy Planning (ONEP), the Industrial Estate Authority of Thailand (IEAT), the Office of Environmental and Pollution Control 13 (Chonburi), and the Provincial Office of Natural Resources and Environment. The report discloses the performance after the implementation of preventive and corrective measures stated in the EIA Monitoring Report in both AMATA City Chonburi and AMATA City Rayong Industrial Estates. 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 2023, 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 feedback and suggestions on environmental-related operations in the industrial estate, the impacts from environmentally-related industrial activities, and issues or complaints related to the environment,

2) to acknowledge the results of the environmental quality monitoring within and outside the industrial estates, and

3) to help distribute accurate knowledge and understanding of environmental management and to foster 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 promoting knowledge and understanding of wastewater and waste management in the community to collectively address issues related to wastewater and waste. This can significantly impact the quality of surface water and community waste management. For instance, the Nong Mai Daeng community project serves as a sustainable model for wastewater and waste management. It is essential to expand such initiatives to other communities surrounding the AMATA City Chonburi Industrial Estate, such as the Khlong Tamru community, Don Hua Lo community, and others in the future.

  • Request for assistance in solving traffic problems, especially at the connecting areas between the industrial estate and the surrounding community, and improving 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 assistance in expanding the Farm to Factory project to surrounding communities on a larger scale. This will facilitate the distribution of local community products and goods to consumers within the industrial estate, while also promoting and supporting the project among factories within the estate. The expansion aims to enrich consumer markets among factory groups, providing additional market channels for factories to access community products through the Farm to Factory project. Whether through factory canteens or factory flea markets, this initiative will bolster the local economy in collaboration with industrial factories within the estate and CSR associations through the AMATA Chuan Shop project.

  • Request support and promotion for expanding the Eco School project to other schools surrounding the AMATA City Chonburi Industrial Estate. This initiative aims to bolster environmental conservation and safety knowledge among youth and community members, while also encouraging active participation in collaborative activities with factories through the Eco Community project of the Industrial Estate Authority of Thailand (IEAT). This collaboration aims to foster community involvement in environmental initiatives.

  • Request better management of the green areas serving as buffer zones adjacent to various communities by measuring, counting, and increasing the number of trees. This aims to mitigate environmental impacts that may affect the communities, such as issues related to unpleasant odors, airborne dust, and excessive noise.

  • Request AMATA City Chonburi Industrial Estate to enhance the utilization of clean energy from solar power systems in various activities within the industrial estate. This can begin with integrating solar energy into centralized public utilities across the estate, such as traffic lights, signals, and street lighting. The initiative can then be expanded to cover the extended areas of AMATA City Chonburi Industrial Estate. Additionally, providing knowledge and supporting community use of solar cells is essential for sustainable development.

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 potential environmental impacts by the factories, such as air pollution, odors, water pollution, and noise pollution, which may negatively affect the community.

  • Request for assistance in addressing traffic issues during rush hours by efficiently managing traffic flow and facilitating traffic management. This includes regulating vehicle speeds and coordinating with the police to establish a collaborative network for stricter traffic discipline.

  • Encourage the AMATA City Rayong Industrial Estate to enhance support for educational activities and offer scholarships to underprivileged children, particularly those in the surrounding communities of the industrial estate.
