Waste Management
We are committed to reducing our waste through our continued focus on improving operational eco-efficiencies and higher resource utilization. We ensure that strong compliance standards are in place to manage the waste at our sites according to regulatory requirements. This includes proper waste inventory by name, type, code (as required by law), storage location, method of offsite transportation, treatment and disposal, quantity of waste generated, and waste stored onsite and disposed of both onsite and offsite. We also ensure that our waste is disposed through sustainable and qualified vendors who reuse, recover or recycle. We manage our waste responsibly, strive to exceed regulatory requirements, and record the quantity of waste generated, stored onsite, and disposed of onsite and offsite. In addition, we carry out site audits of key vendors to ensure that their waste management standards are in-line with approved local regulations in addition to our sustainable practices.

Note:
- Intensities are calculated based on overall production including inter-company sales.
- 2020 and 2021 environmental data has been restated using a more stringent definition and methodology.
- 2020 baseline was adjusted for an alignment.
Indorama Polyester Industries (Rayong) has been continuously implementing a zero waste to landfill program since 2021. One of the methods we use to manage waste is by sending production waste, including off-grade products from the fiber production process such as polymer waste, POY waste, and fiber waste, to legally certified companies. These companies will use the waste as raw materials for further fiber production. In 2023, we sent 2,247,738 kgs of production waste to these companies, accounting for 68.8% of all non-hazardous waste generated. This initiative significantly reduces waste to landfill and helps the site achieve its goal of a 99.20% diversion rate per year.
In 2023, Indorama Ventures Mobility Scottsboro launched a project to improve the quality of Nylon 66 yarn products, specifically focusing on SDW (Spinning, Drawing, Winding) A Grade. This initiative involved optimizing process profile settings (including extruder temperature and draw field settings), reducing downtime caused by breakouts, and addressing equipment issues. Consequently, productivity will increase from 81.7% to 88.6%, resulting in cost savings of approximately $755,000 per year. This initiative will not only enhance overall operational efficiency but also significantly reduce production waste, such as C-grade products, leading to a more efficient use of resources.
In 2024, Petform (Thailand) Limited - Lopburi implemented a project to reduce hazardous w a s t e g e n e r a t e d d u r i n g m a c h i n e r y maintenance. The project involved revising maintenance plans and procedures to prevent hydraulic oil leaks and reduce the use of rags, which become contaminated materials that require disposal. Additionally, training sessions were conducted to educate employees on operational methods and waste management, raising awareness about waste reduction and improving operational practices. As a result of these activities, it is expected that contaminated rag waste will be reduced by 22%, and the amount of oil sent for disposal will decrease by 34%, compared to the waste generated during machinery maintenance in 2023.

Indorama Synthetics (India) has successfully implemented an automatic chemical dosing system for two of their cooling towers. This represents a significant advancement in automation and digitization, and offers numerous advantages over manual dosing. The automated system ensures that the desired level of chemicals is consistently maintained in the system, preventing both corrosion and scaling caused by underfeeding, in addition to chemical waste due to overfeeding.
Performance Fibers (China)
Indorama Ventures fully supports China’s policy of reducing emissions and increasing energy efficiency while promoting technological progress. This is also integral in achieving our sustainability goals which are aligned with our vision: To be a world-class sustainable chemical company making great products for society.
Our Performance Fibers subsidiary in China focused on improving resource efficiency and reducing chemical waste. The chemical waste produced from tire cords consists of a complex structure, does not biodegrade easily and carries high treatment costs. the division initiated a project to reduce chemical consumption in its production process.
