Waste Management

Why is this Important?

Waste Management is a crucial issue in the power sector, as improper handling of waste can lead to potential impacts on environment and safety of surrounding communities. Systematic waste management helps reduce the risks related to the environment, contamination, operational challenges, and compliance with relevant regulations. Without appropriate controls, this may affect long-term stakeholder trust.

EGCO Group strengthens its waste management approach by applying the Circular Economy concept as an operational framework to maximize resource efficiency and reduce waste throughout the entire operational process. In addition, EGCO Group adopts advanced technologies and innovations to enhance waste management efficiency, material reuse, and related cost control, together with mitigating risks associated with resource scarcity and environmental impacts. This approach supports sustainable business operations and creates shared value for the organization, communities, and society.

EGCO Group follows the 3Rs Waste Management Principle, namely Reduce, Reuse, and Recycle, to minimize the amount of hazardous and non-hazardous wastes generated from the organization’s operations to a minimum. Wastes are managed systematically through segregation, collection, transportation, and disposal, supplemented by waste audits to identify opportunities for improving waste performance, such as record examinations, facility walk-throughs, and waste sorting. Data are collected and reported through the waste management data collection system. Waste data, including waste diversion from landfills, is verified by a third party and certified by an independent, accredited body as part of ISO 14001. (For third-party verification, please see the independent assurance opinion statement for GRI 306-4 Waste diverted and GRI 306-5 Waste directed to disposal.) To reflect this practice, PAJU ES has achieved “Zero Waste to Landfill (ZWTL)" with silver grade, certified by the global certification company, UL Solutions. Additionally, a review of waste management approaches and auditing of waste treatment and disposal contractors has been conducted on a regular basis to ensure that all operational processes comply with relevant regulations and requirements.

3Rs Principle of Waste Management

Reducing current usage or optimizing the number of materials used means minimizing the amount of waste generation, e.g.,

Reduce paper usage by transitioning to an E-Document system and online approval workflows
Encourage employees to bring personal containers or reusable cups as alternatives to single-use plastic cups and bottles, reducing plastic waste within power plants
Control the requisition of office supplies and consumables in proportion to workload requirements
Repurpose materials or spare parts from maintenance works that remain in usable condition for CSR projects or social activities, reducing new material procurement, minimizing operational waste, and promoting optimal resource utilization in line with the Circular Economy concept

Action plans to reduce waste generation are continuously developed and implemented, focusing on optimizing resource usage and minimizing waste at every stage of operations.

Reusing is the most efficient way to utilize resources by using items multiple times. Some materials may be reused several times e.g.

Sort single-sided paper for reuse in internal printing or temporary documents
Redistribute unused but serviceable materials or equipment to other departments within the organization

Recycling involves sorting waste into different categories that can be reused and reintroduced into the production process, helping reduce the amount of waste sent to landfills. The integration of recycling programs supports EGCO Group’s goal of minimizing environmental impacts.

EGCO Group has implemented various waste management and environmental initiatives across its operations. One notable project is the EGCO Ecosystem, which has been expanded to 13 power plants and the Khanom Learning Center. EGCO Group has also supported the proper disposal of electronic waste. In the future, EGCO Group aims to increase recycling rates and improve the separation of orphan waste to be used as fuel for energy production. Additionally, EGCO Group implements the “Leaf Fertilizer” project, which recycles organic waste into fertilizer for planting, as well as the “Electronic Waste and Seedling” project to create green spaces in Bangkok.

These initiatives promote proper waste sorting and disposal, with the goal of raising environmental awareness among employees. To further support these efforts, training on waste reduction is provided to all employees, equipping them with the necessary skills and knowledge to identify and implement effective waste management practices.

Furthermore, EGCO Group has implemented a comprehensive approach to managing fly ash from its power plants, emphasizing innovation and R&D on recycling to minimize environmental impact. EGCO Group collaborates with Pozzolanic Philippines Inc. (PPI) to reuse fly ash generated at their facilities as raw material for cement and other construction materials. This integration of recycling programs ensures that the waste from own operations sent to landfill is dramatically reduced. Moreover, the process not only helps in reducing the amount of fly ash produced but also significantly cuts down on landfill-related greenhouse gas emissions.

At the Khanom Power Plant, a significant initiative is the composting project, which converts organic waste like leaves and grass into compost. This project helps reduce the reliance on chemical fertilizers and promotes a more sustainable approach to waste management.

EGCO Group has also been recognized for its effort in waste management at national and regional levels with awards such as the "Low Carbon Business: Waste Management Award" from the "Vibhavadi Road Zero Waste" project and the "Asia Responsible Enterprise Awards" in the Green Leadership category from Enterprise Asia. These awards reinforce the EGCO Group's commitment to reducing environmental impact and promoting sustainability.

These initiatives reflect EGCO Group's commitment to adhering to the 3Rs principle (Reduce, Reuse, Recycle) and showcase their proactive approach in minimizing waste and enhancing sustainability across their operations and communities.
