Objectives/Goals 

PTT has strategically set objectives to eliminate the disposal of hazardous waste from industries via landfilling to zero*. This initiative has been collaboratively pursued by the PTT Group since 2015, culminating in its achievement by 2020. Subsequently, the scope has been broadened to include the elimination of non-hazardous waste from industries via landfilling by 2023.

Furthermore, long-term goals related to enhancing and supporting operations in alignment with the circular economy, including the adoption of the BS 8001:2017 standard within the PTT Group to manage waste throughout the value chain, have been outlined as follows:

• Attain a Maturity Level of 3 by 2030.
• Ensure that at least 50% of the waste managed** by the PTT Group is recycled by 2030.
• Establish operational framework in 2024 for PTT Group to avoid Scope 3 emissions from waste disposal activities, aiming to achieve a reduction of 0.67 tons of carbon dioxide equivalent per ton of total waste generated.

Waste Management Guidelines

PTT implements waste management strategies under the SSHE Management System by establishing comprehensive policies, long-term and annual objectives and targets.  We meticulously monitor and supervise operations to ensure compliance with legal requirements, industry standards, best practices, corporate policies, and internal procedures. This includes regular assessments of effectiveness and outcomes within the SSHE governance structure, reviewed quarterly. Moreover, we prepare detailed reports for regulatory bodies and maintain transparent, ongoing communication with stakeholders.

PTT’s commitment to waste management encompasses both hazardous and non-hazardous waste, guided by the principles of the 5Rs: REDUCE, REUSE, RECYCLE, RENEWABLE, and REFUSE. By adhering to these principles, we aim to control, prevent, and minimize waste generation at its source. Additionally, we integrate Circular Economy principles in line with the BS8001:2017 standard across all operational phases, from business development and product design to production processes, construction, operations, transportation, utilization, and disposal. Our focus on reuse and recycling ensures efficient resource utilization and reduces waste generation.

Key Initiatives 

Implementation of Circular Economy principles according to the BS8001:2017 standard

PTT is committed to advancing the application of Circular Economy principles within the organization to achieve the Maturity Level of 3 referenced by the British Standards Institution: Framework for implementing the principles of the circular economy in organizations – Guide (BS 8001:2017) by 2030.

Furthermore, the PTT Group continuously evaluates guidelines and opportunities for operational enhancements to promote Circular Economy practices across the value chain. Annually, selected guidelines are studied and collaboratively implemented under the "Turning potential project to Business Model" initiative. In 2023, PTT undertook studies, developed innovations, and executed Circular Economy projects, totaling 2 projects, which included:

1. Calcium Silicate Insulation Waste Upcycling: Researching the utilization of post-service Calcium Silicate insulation to produce value-added items like desks and chairs. Presently, these products are installed and utilized at PTT's headquarters and natural gas separation plants in Rayong.
2. Collaborative Development of Advanced Materials from Manufacturing Waste: Creating reusable equipment from manufacturing process waste, aligned with Circular Economy principles, to optimize resource usage responsibly and minimize environmental impact. Advancing this initiative, we recycled plastic crates and soda bottles made from rPET and rHDPE pallets from rHDPE and molasses residue, in partnership with Boon Rawd Brewery Co., Ltd., PTT Public Company Limited, and IRPC Public Company Limited.

Exploring PTT Group's Waste Database to Advance Zero Waste Objectives

PTT has meticulously analyzed trends and compiled data regarding the management of both hazardous and non-hazardous waste stemming from industrial activities within the PTT Group. The aim is twofold: to evaluate enhancement strategies for waste disposal methodologies and to uncover business prospects through recycling and waste management initiatives. Practical workshops and knowledge-sharing sessions are regularly organized within the PTT Group. These include discussions on innovative processes like the extraction of valuable metals using accelerant chemicals to generate colored ceramic powder, aligning with principles of the circular economy. This dissemination of knowledge serves as a guiding light for PTT Group members to implement similar practices within their respective organizations. Furthermore, for waste necessitating disposal, PTT ensures strict adherence to established standards and regulations.

Management of Non-hazardous Waste 

PTT places a paramount emphasis on waste segregation procedures across all operational sites. Adequate waste receptacles are provided for segregating diverse waste categories, encompassing organic, general, and recyclable waste. Additionally, concerted efforts are undertaken to educate and heighten awareness among employees to curtail waste generation. These educational endeavors are conducted through various platforms such as websites, printed materials, and nationwide awareness campaigns . In 2023, particular attention was directed towards segregating health masks, considered infectious waste, to mitigate the spread of COVID-19 among employees in the workplace. PTT actively participated in the "No Waste" initiative, a collaborative endeavor between the Securities and Exchange Commission (SEC) and the Thailand Responsible Business Network (TRBN). This initiative is geared towards optimizing waste management practices, augmenting reuse rates, and minimizing waste destined for landfills.

Management Waste Derived from Product Usage within PTT Group

The PTT Group is steadfast in its commitment to maximizing the repurposing of plastic waste. Through a collaboration between PTT and PTT Oil and Retail Business Public Company Limited, a "Memorandum of Understanding for the Development of Plastic Waste Recycling Using Amazon Café in Pilot Projects" was signed. Spearheaded by research and development efforts, a prototype machine utilizing QR code technology was devised for collecting plastic cups from Amazon cafes. These cups are subsequently transformed into Tumbler Upcycling glasses. The prototype machine was installed at the Energy Complex headquarters. In 2021, more than 544 PET plastic cups were collected, resulting in the production of over 90 Tumbler Upcycling glasses. This initiative led to a significant reduction in plastic waste by over 8.7 kilograms, translating to a decrease of 8.97 kilograms in carbon dioxide emissions.

Research and Development of Upcycled Products: Transforming Insulation Waste into Circular Economy Products 

The Environmental Taskforce (E-TF) within the PTT Group collaborates to investigate strategies for repurposing waste to bolster circular economy endeavors, aiming to diminish waste volume while uncovering business prospects through effective management and recycling practices. In 2023, the team delved into the methodology of upcycling post-service Calcium Silicate insulation waste, transforming it into functional items like tables, chairs, and plant pots. These upcycled products were subsequently installed and integrated into the facilities of PTT's offices.

Establishing Targets to Reduce Scope 3 Greenhouse Gas Emissions in Support of Circular Economy Initiatives

PTT Group's Assessment of Scope 3 Greenhouse Gas Emissions and Circular Economy Initiatives. PTT Group has evaluated the significance of its activities and reported data on the intensity of other indirect greenhouse gas emissions (Scope 3), including: Transportation and distribution of raw materials, Transportation and distribution of finished products, Waste disposal from the production process, Business travel. PTT Group recognizes these areas as challenges and opportunities to drive greenhouse gas reductions and support a circular economy. The group aims to maximize the reuse of waste. In 2024, PTT Group will begin implementing a framework to avoid other indirect greenhouse gas emissions (Scope 3) (GHG Avoidance) from waste disposal activities. The target is to achieve 0.67 tons of carbon dioxide equivalent per ton of total waste generated.

Collaborative Partnerships with External Entities

The PTT Group has joined forces with the Synphaet Medical Hospital Group to initiate the "We Love the World and the World Loves Us" project. This collaborative endeavor focuses on creating designated collection points for used plastic medicine pouches sourced from hospitals within the Synphaet Medical Hospital Group, located at four strategic locations.
