Positive and Negative Impacts

Impact of Issues over Time

Objectives/ Targets 

PTT has set a strategic goal to achieve zero* hazardous industrial waste disposal through landfilling, a target that the PTT Group has been working towards since 2015 and successfully achieved in 2020. Building on this success, the Group has expanded the target to eliminate the landfill disposal of non-hazardous industrial waste by 2023. 

In addition, PTT has established long-term objectives to enhance and support operations based on circular economy principles. This includes adopting the BS 8001:2017 standard within the PTT Group to manage waste across the entire value chain, with the following goals: 

The application level, or Maturity Level, is set to reach 3 by 2030. By this year, the PTT Group aims to manage at least 50% of its waste** in a circular manner. In 2024, the PTT Group has established operational guidelines to mitigate indirect greenhouse gas emissions (Scope 3) resulting from waste disposal activities in production processes, with a target of 0.67 tons of CO2 equivalent per ton of waste generated. 

To comprehensively measure the circular economy performance across the PTT Group’s operations, including activities related to production processes and products sold, PTT is currently exploring models to establish additional indicators. These indicators will provide a framework for monitoring waste management activities from production processes and sold products, and will further enhance the Group’s circular economy goals in the future. 

Waste Management Guidelines

PTT manages waste under its SSHE management by setting policies, long-term and annual goals. The Company continuously monitors, measures, and supervises operations to ensure compliance with relevant laws, standards, policies, targets, and procedures. The performance and effectiveness of these operations are reviewed quarterly, as part of the SSHE governance structure. Additionally, PTT reports to government agencies and ensures transparency by consistently disclosing relevant information to stakeholders. 

PTT is committed to managing both hazardous and non-hazardous waste through the application of the 5Rs principles: REDUCE (minimize usage to the necessary amount), REUSE (reuse materials), RECYCLE (process materials for reuse), RENEWABLE (utilize renewable resources), REFUSE (avoid using environmentally harmful substances). These principles are implemented to control, prevent, and reduce waste generation at the source. Furthermore, PTT integrates the circular economy principles, based on the BS8001:2017 standard, across its entire operation—from business development, product/service design, production process design, construction, operations, transportation, usage, and disposal. The focus is on reusing and recycling materials to optimize resource use, enhance efficiency, and minimize waste production. To ensure widespread understanding of waste management and circular economy principles throughout the organization, PTT offers training to employees on these topics. This initiative is aimed at reducing waste and improving waste management systems, covering all aspects such as business development, product design, construction, operations, transportation, utilization, and disposal. The ultimate goal is to promote the reuse and recycling of materials. 

Key Initiatives 

Adoption of Circular Economy Principles according to the BS8001:2017 Standard 

To enhance the implementation and performance measurement of circular economy practices, PTT, in collaboration with its subsidiaries, has set a target to elevate the application of circular economy principles within the organization to achieve Maturity Level 3 based on the British Standards Institution: Framework for Implementing the Principles of the Circular Economy in Organizations – Guide (BS 8001: 2017) by 2030. 

In 2024, PTT Public Company Limited, PTT Oil and Retail Business Public Company Limited, and Global Power Synergy Public Company Limited launched a pilot project to undergo an assessment based on the circular economy principles (Maturity Level) in an organizational context, conducted by an external third-party assessor, following the British Standards Institution: Framework for implementing the principles of the circular economy in organizations – Guide (BS 8001: 2017). The assessment results showed an average score of Level 2, which aligns with the Company’s internal goal of achieving circular economy operations (Maturity Level) at Level 2 by 2024. To ensure the organization meets its set objectives, the Group companies have developed plans to scale up and enhance operations, aiming to reach the target by 2030. 

Furthermore, the PTT Group has been exploring and analyzing opportunities to enhance the application of circular economy principles across its entire value chain. Each year, specific approaches are selected for study and joint implementation under the "Circular Economy Pilot Projects within PTT (Turning Potential Projects into Business Models)." Since 2022, PTT has been actively involved in studying, developing innovations, and executing several major circular economy initiatives, including: 

• Calcium Silicate Insulation Waste Upcycling: This initiative investigates how used calcium silicate insulation materials can be upcycled into value-added products, such as tables and chairs. These products are currently being used at PTT’s headquarters and at the Rayong Natural Gas Separation Plant. 

• Collaboration for Innovation in Upcycling Manufacturing Waste: This project aims to create returnable equipment using circular economy principles, promoting efficient resource use and minimizing environmental impact. A pilot program is focused on recycling plastic into prototype products, such as water and soda crates made from rPET and rHDPE pallets, as well as malt residue. This initiative involves Boon Rawd Brewery Co., Ltd., PTT and IRPC 

• Development of Wood Plastic Composite (WPC): In collaboration with PTT Oil and Retail Business and IRPC, PTT is developing Wood Plastic Composite (WPC) products by upcycling used lubricating oil cans. These materials are then used to produce furniture and interior decor for FIT Auto service centers. The project has been successfully expanded to cover 30 branches nationwide. 

• Rainwater Collection and Treatment for Cooling Tower Use: Since 2023, PTT has been developing an innovative Rainwater Treatment System designed to collect and treat rainwater for use in cooling towers, thereby reducing reliance on municipal water sources for office buildings. This system is currently being expanded into a business model, with plans to offer design services and products to external clients.

Setting Targets for Reducing Other Indirect Greenhouse Gas Emissions (Scope 3) to Support GHG Reduction and Circular Economy Initiatives 

Partnerships and Collaborations with External Organizations 

To promote the identification of opportunities for waste reuse in line with circular economy principles and contribute to national GHG reduction efforts in the waste sector, PTT, through the Innovation Institute, has developed an innovative prototype called "Pan Phui." This initiative focuses on breeding Black Soldier Flies (BSF) to manage organic waste in Thamanao, Lopburi Province, which serves as a pilot area for learning and scaling social business opportunities under the Creating Shared Value (CSV) model. This project aims to reduce organic waste by up to 300 kg per month and prevent the release of up to 55 kg of CO2 equivalent per month. The BSF larvae produced will be utilized as alternative protein for animal feed and as fertilizer to enhance agricultural productivity in the local community.
