Positive and Negative Impacts

In carrying out PTT’s operational activities in all functional areas, including office buildings as well as operating areas located in different regions across the country, waste generation from operational activities will inevitably more or less likely pose harmful impacts to the environment, community and the surrounding due to different types of waste excretion. PTT places utmost importance on waste control, prevention, and reduction at its origin source, of both hazardous and non-hazardous waste, based on the 5Rs principle. The principles are as follows: REDUCE with conscious consumption or use as necessary, REUSE, RECYCLE, RENEWABLE, and REFUSE to use environmentally unfriendly substances, as well as applying the principles of the CIRCULAR ECONOMY, which is one of the “BCG economic models” or Bio-Circular-Green Economy Model, to extend the complete waste management following the country’s policy. It helps elevate the production process’s efficiency while reducing the company’s waste treatment and disposal costs, reducing environmental and communal impacts while allowing for a healthier quality of life for citizens in the long run.

PTT recognizes that comprehensive and efficient waste management is a collective responsibility that all related sectors in the country must partake in systematically. Therefore, PTT is ready to spearhead mechanisms to help drive continuous development and elevation of management standards.

Objectives/Goals

PTT has set strategic targets to reduce the volume of the hazardous industrial waste landfill to zero to enable the decreasing trend since 2015, which the mark has achieved in 2020. Nonetheless, PTT has set long-term targets for the year 2030 to enhance the application of circular economy principles following BS8001:2017 to PTT Group to manage waste throughout the value chain as follows:

• Elevate Maturity Levels to 3 by 2030
• Amount of waste** managed in circulation of PTT Group shall not be less than 50% by 2030

Management Approach^{GRI 306-2 (2020)}

PTT regulates waste following the SSHE Management System approach by establishing rules, setting long-term and annual goals, and monitors and measures under corporate laws, standards, guidelines, policies, plans, and operational processes. According to the SSHE governance structure, its efficiency and effectiveness are reviewed quarterly. Reports are prepared for government agencies and disclose information to stakeholders with transparency and continuity.

PTT focuses on the management of waste encompassing hazardous and non-hazardous waste based on the 5Rs principle, following Reduce with conscious consumption or use as necessary, Reuse, Recycle, Renewable and Refuse, the rejection of environmentally unfriendly substances to best management, fully prevent and reduce waste at its source. In addition, PTT’s integration of its circular economy principles according to BS8001:2017 adaptation into its operational business development, product, service, production design, construction, transportation operations, application, and decommissioning of carcass disposal in full circle with importance placed upon recycling to ensure efficient resource utilization and minimal waste production.

Projects/ Key Initiatives

Application of Circular Economy Principles in Accordance to BS8001:2017^{GRI 306-3 (2020), GRI 306-4 (2020), GRI306-5 (2020)}

To achieve Maturity Level 3 following the British Standards Institution: Framework for implementing the principles of the circular economy in organizations Guide (BS8001: 2017), PTT Group has studied and examined regulations because of its objective to apply circular economy principles to its business operations.

To better align with principles, PTT Group has studied and analyzed operational approaches and opportunities to enhance the application of circular economy principles throughout the value chain. Each year, approaches will be selected for research and co-implemented under the “Turning potential project into a business model.” In 2022, PTT, in conjunction with PTT Oil and Retail Business Public Company Limited, has conducted three research, monitoring and implementation of the circular economy projects as follows:

1. Approximately 1,527 used lubricant cans (509.2 kilograms of recycled plastic pellets) were used to produce 760 traffic cones to replace those at PTT fuel stations.
2. Approximately 16,740 used lubricant cans (5,580 kilograms of recycled plastic pellets) were used to produce wood substitutes as furniture for 9 Fit Auto store branches.
3. Collaborated with PTT group external partners to recycle lubricants to be produced as alternative fuels with a total accumulation of 700,000 liters of up cycled fuel.

Study of PTT Group's Waste Database to Support Zero Waste Goals 

PTT has used data on hazardous and non-hazardous waste management from PTT Group’s industries to analyze trends and create a database of waste management methods. These are to evaluate the improvement of the disposal method and business opportunities from recycling and waste management, including organizing workshops and exchanging knowledge within the PTT Group, such as a workshop of precious metal extraction with catalysts to produce ceramic pigments creating value according to the principles of the circular economy, for instance. Sharing such knowledge can be a later guideline for PTT Group to adapt within their companies. For waste that needs to be disposed of, PTT has managed to dispose of waste under the standards and laws specified.

Non-hazardous Waste Management

PTT prioritizes the waste separation process in workplace environments and has designated waste separation bins, such as organic, general, and recycling bins, amongst work areas. Moreover, PTT seeks to communicate information through several channels, including its website and newspaper publications, focusing on increasing employee awareness and comprehension about waste reduction, including garbage classification. The following marketing activities have been planned in every operating region across the nation. To avoid COVID-19 from propagating amongst employees in 2020, PTT Group treats face mask separation and disposal as being of utmost concern. Moreover, PTT Group has undertaken the “Vibhavadi Zero Waste” program, which runs by the Office of The Securities and Exchange Commission in conjunction with the Thailand Responsible Business Network (TRBN). The initiative encourages private businesses along Vibhavadi Road to work together to establish efficient trash management strategies, boost recycling rates, and decrease waste discharge.

Management of Waste Generated from PTT Group’s Product Consumption

Some of PTT Group’s main products are petroleum, natural gas, and petrochemicals like plastic. The Group has committed to collecting as much plastic waste as possible for recycling. As a result, PTT and PTTOR have signed a Memorandum of understanding for developing a recycling method for plastic waste from Café Amazon that will be used in its pilot project. The initiative calls for research and analysis to create a prototype container for café Amazon’s plastic trash employing QR code technology, which enables the separation of plastic cups to simplify waste collection for the tumbler up-cycling process. These trash cans, which were placed in the offices of the Energy Complex Building, allowed for the collection of more than 923 PET plastic cups in 2021. This volume can be used to recycle up to 153 tumblers while reducing 18 kilos of plastic waste, which equates to 19 kilograms fewer emissions of greenhouse gases (CO2eq).

Partnership and Cooperation with Related Stakeholders

PTT Group and Synphaet Hospital Group partnered to establish four stations for the collection of used plastic medicine packets from the hospitals within the Synphaet group as part of the campaign "We love the world, the world loves us" project to up-cycle plastic pill bags into a higher value product in substitution for disposal.
