AMATA Industrial Estates in Thailand host over 1,356 industrial factories and tenants, employing over 300,000 workers, and generating massive amounts of waste and industrial waste annually. If the factories fail to comply with laws on solid waste and industrial waste management, they could cause negative impacts on the health of waste workers, the environment, and nearby communities in both the short and long term. Additionally, it could potentially affect the Company's ability to obtain future expansion licenses.
Efficient waste management and creating additional value from waste through circular economy principles offer a business opportunity for the Company to develop new products and services that lower its costs, increase revenue, build stakeholder confidence, be recognized by the local community, and also support the reduction of greenhouse gas emissions from landfills.
The Company places strong emphasis on waste management throughout the entire business value chain—from waste generation to final disposal. Accordingly, it has established a “Waste Management Policy” to minimize environmental impacts from operations within the industrial estates. This is achieved through proper waste management practices that comply with legal requirements, environmental standards, and scientific principles. The Company also promotes recycling and reuse among factories within the estates and encourages the use of modern innovations and technologies to reduce the generation of solid and industrial waste. The Company is responsible for managing only solid waste and non-hazardous industrial waste on behalf of customers operating within the industrial estates. The management of hazardous waste remains the responsibility of individual factories, in accordance with the Industrial Estate Authority of Thailand Act B.E. 2522 (1979), the Factory Act B.E. 2535 (1992), and the Public Health Act B.E. 2535 (1992).

The Company has assigned its subsidiary, AMATA Facility Services Company Limited (AFS), to oversee the waste management of factories in both industrial estates in Thailand in accordance with relevant laws under the Industrial Estate Authority of Thailand Act B.E. 2522 (1979), the Factory Act B.E. 2535 (1992), and the Public Health Act B.E. 2535 (1992). The Company’s solid waste management service is now used by 609 factories in AMATA City Chonburi Industrial Estate, and 310 factories in AMATA City Rayong Industrial Estate, representing 71.90 % and 60.90 % of total tenants and factory operators in each industrial estate respectively which increase from 2023.
In 2024, the Company generated a total of 34,432.20 tons of waste from its operations at AMATA City Chonburi Industrial Estate, AMATA City Rayong Industrial Estate, and its Bangkok office. This total comprises 23,061.76 tons of waste from AMATA City Chonburi Industrial Estate, 11,365.24 tons from AMATA City Rayong Industrial Estate, and 5.20 tons from the Bangkok office. The waste generated this year was entirely non-hazardous, including solid waste from Company operations, solid waste from the Company’s utility systems, and solid waste from factories that use the Company’s waste management services.
The Company employs various waste management strategies to ensure efficient and appropriate handling based on waste type. The approach aligns with its policy of maximizing resource efficiency while minimizing environmental impact. In 2024, all generated waste was managed through the following methods: 20.8% was reused, 6.1% was recycled, 46.7% was incinerated for energy recovery (waste-to-energy), and 26.4% was disposed of via landfill.
The Company recognizes the impact of landfill waste disposal, which generates greenhouse gases that are a major cause of climate change. As a result, the Company has set a bold target of achieving Zero Waste to Landfill each year. This ambition is guided by a comprehensive approach that focuses on reducing resource consumption, minimizing waste generation from the outset, enhancing waste segregation efficiency, and embracing the principles of a circular economy to ensure the maximum reuse of resources.
In addition, the Company places great emphasis on engaging its stakeholders in waste management efforts. By promoting responsible resource use and maximizing resource efficiency in line with circular economy principles, the Company encourages both internal and external stakeholders to collaborate in the proper disposal of waste and to increase the reuse or recycling of waste within their respective operations.
The total amount of solid waste generated in both industrial estates is 27,646 tons, categorized as follows: solid waste from factories utilizing the Company’s waste management services at AMATA City Chonburi Industrial Estate, amounting to 18,084.90 tons; at AMATA City Rayong Industrial Estate, amounting to 7,887.86 tons; and solid waste from the Company’s operations in the common areas, including tree branches and wood debris from pruning, totaling 1,673.24 tons. Of this, 932.86 tons of solid waste from the common areas at AMATA City Chonburi Industrial Estate was managed by the Company, while 740.38 tons of solid waste from the common areas at AMATA City Rayong Industrial Estate was managed by the Company’s contractors.

Solid waste from factories using the Company’s waste management services is separated by contractors at the waste separation plant within the AMATA Industrial Estate. The waste is sorted according to the principles of the 3Rs (Reduce, Reuse, Recycle) and then disposed of through various methods by contractors who are qualified and licensed to manage solid and industrial waste in compliance with the law. Additionally, the Company implements waste management strategies from the source, providing guidance to factories using the Company’s waste disposal services on proper waste separation and classification before sending it to the waste separation plant. This ensures that the waste entering the sorting process is of high quality and can be utilized in the production of Refuse-derived Fuel (RDF) or recycled materials, with the goal of minimizing the amount of waste that cannot be repurposed and must be sent to landfill disposal, ideally reducing it to zero.
Since 2011, the Company has continuously worked to reduce the amount of waste sent to landfills at the AMATA City Chonburi Industrial Estate, in alignment with its policies and goals. To achieve this, the Company has focused on enhancing waste management practices, shifting from landfill disposal to sorting recyclable waste and producing alternative fuels in the form of Refuse-derived Fuel (RDF), which is then used as fuel for co-incineration in cement plants.
Remark; the information of downstream waste management is calculated based on the actual waste sent to waste processors.
In 2024, the Company successfully separated 11.56% of recyclable waste and 88.44% of waste suitable for Refuse-Derived Fuel (RDF) production from the total solid waste processed at its waste separation plant in AMATA City Chonburi Industrial Estate. Through these efforts, the Company achieved a remarkable milestone—reducing landfill disposal to 0% of the total solid waste managed at the facility.
Through the implementation of the Zero Waste to Landfill approach, the Company successfully reduced waste management costs by 2.4 million baht in 2024. Furthermore, 80% of factory operators utilizing the Company's waste management services expressed satisfaction and confidence in its practices, ensuring that no waste was illegally disposed of. Additionally, neighboring communities of AMATA City Chonburi Industrial Estate have shown increased trust in the estate’s waste management system, reinforcing its commitment to responsible and sustainable waste disposal. Building on the success of implementing the Zero Waste to Landfill approach, the Company is currently conducting a feasibility study to expand the initiative to AMATA City Rayong Industrial Estate.
The majority of waste generated from the operations within the industrial area’s core processes consists of sludge, which results from the water production system and the biological wastewater treatment system at both AMATA Industrial Estates. This sludge is classified as non-hazardous waste. In 2024, the Company generated a total of 6,781 tons of sludge, with 4,044 tons from the AMATA City Chonburi Industrial Estate and 2,737 tons from the AMATA City Rayong Industrial Estate. The Company conducted an analysis of the sludge quality using 12 different tests, using the Total Threshold Limit Concentration (TTLC) and Soluble Threshold Limit Concentrations (STLC) methods. The results indicated that the toxicity levels of the sludge were below the standards set by the Ministry of Industry's Notification on the Management of Waste and Used Materials, B.E. 2566. As a result, the Company has fully reused 100% of the sludge within the industrial estates, utilizing it for landfilling and as soil for tree planting.
The Company encourages all employees to participate in reducing waste and garbage in the office by creating communication campaigns to promote understanding and awareness of proper waste management. Additionally, it has implemented the "All Save, All Win" project through various activities as follows:
Employees are provided with waste management guidelines and best practices via the Line application across all office locations—Bangkok, Chonburi, and Rayong—ensuring accessibility and efficiency in communication. Additionally, quarterly employee meetings incorporate waste management awareness discussions to reinforce proper segregation, disposal, and recycling measures.
Promoting the reduction of paper usage in offices to minimize waste generation in all Company offices and promoting wastepaper recycling, the Company cooperated with SCG Packaging Public Company Limited to develop the "The "Old for New" Paper Recycling Initiative aims to reduce resource consumption and waste generation by collecting used paper from Company offices for recycling and repurposing. This initiative contributes to natural resource conservation, waste minimization, and environmental impact reduction. In 2024, a total of 1,087 kilograms of used paper was recycled through this program.
Food waste reduction from the point of generation. Employees participate in pre-selecting lunch menus to reduce food waste at the source and minimize food leftovers. Additionally, food and beverages are provided in environmentally friendly packaging made from 100% recycled PET (rPET) plastic pellets at break rooms, in accordance with the Chief Executive Officer’s policy. In 2024, the Company (Bangkok office) generated 2.50 tons of food waste, according to calculations based on the Food Waste Index Report 2024.
