Sustainable Development Goals


Opportunities and ChallengesGRI 306-1(2020)

Thailand has established the “BCG economic model” or Bio-Circular-Green Economy Model as a “national agenda” to direct Thailand towards the goal of becoming a high-income country while fulfilling Sustainable Development Goals (SDGs) in 2021. This model emphasizes the consumption of resources for maximum benefit, cost-effectiveness, waste amount reduction to less than or equal to zero, raw materials utilization from natural sources in addition to environmental friendliness for target industry groups. The mentioned industry groups, which comprise of 4 main sectors, encompass the energy industry, materials and biochemical industries, and industries related to the business operations of PTT and the PTT Group. Therefore, the implementation of this model as a facet of business strategy adjustments aims to promote development and increase distribution proportion of biobased products extracted from raw materials of natural origin and environmentally friendly products. Through integrating circular economy principles into business operations, further reduction of resource utilization and waste amount reduction is systematically enabled. 

Factors including urban expansion, population increase, and changes in consumer behavior also changing lifestyles and working from home due to COVID-19 have resulted in solid waste surges in 2020 to 25.37 million tons. 24% of this waste is improperly disposed of and consequentially causes degradation of living things and natural resources, with instances of wildlife and marine animal death from ingesting the solid waste, soil and groundwater contamination from waste water, as well as issues about unpleasant odours and destruction of scenery from improper waste disposal. In addition to solid waste, industrial waste has increased due to the industrial sector growth and thus may cause toxic residues and contamination in the environment, if not disposed of properly.  With the initiation of the governmental 20-year master plan to formulate preventions and solutions for pollution arising from waste and hazardous waste (2018-2037), industrial waste and solid waste must be properly disposed of by 2020 and 2026, respectively. Among the measures instituted within this master plan is the focus on prevention and reduction of pollution from waste and thus, operators are expected to utilize resources cost-effectively and produce minimal pollution.

PTT is fully aware that waste management is not the role and responsibility of any particular authority, but the duty of everybody in the country. Therefore, PTT emphasizes on developing its operation procedure to reduce waste from upstream to downstream operations; this includes the application of the upcycling process to make the most of resources,  under circular economy principles. 

Management ApproachGRI 306-2 (2020)

PTT manages waste following the SSHE Management System approach, determines policies, and long-term and annual goals in addition to monitoring and measuring in line with corporate laws, standards, guidelines, policies, goals and business processes. There is a quarter review on its efficiency and effectiveness according to the SSHE governance structure. This approach enables the review of efficiency and effectiveness according to the specified regulatory structure while preparing reports to government agencies and disclosing information to stakeholders in a transparent and continuous manner. 

From PTT’s target to reduce the volume of hazardous industrial waste landfilled to zero, PTT Group has been working to enable the decreasing trend since 2015, aspiring to operate per circular economy principle. PTT’s primary waste management includes recycling and extending of product’s lifespan through constant research and studies on innovation of management approaches as well as the adoption of new technology per international standards. The current goal for zero waste disposal by landfill has been extended to non-hazardous industrial waste by 2022. The PTT Group treats waste management in every activity of the value chain as of great importance; this includes management of waste generated from upstream petroleum & gas operations, from the downstream petrochemical operation, waste at on-site operations and waste from consumption of PTT Group’s product


Excluding industrial waste from the following cases;
1. Department of Industrial Works (DIW) or the state agency incharge does not allow waste disposal by other methods.
2. Industrial waste that is unable to be recycled due to a lack of supporting technology in the country
Somehow, the management is to comply with the criteria for DIW’s Zero Waste to Landfill Achievement Award.

PTT has analyzed flagship companies’ industrial waste management data and developed a database on waste management approaches assess changing approaches in waste treatment. The company has also organized seminars for knowledge-sharing within PTT Group, such as the extraction of valuable metal with catalysts to produce a ceramic color powder. The approach yields value according to circular economy principles. Knowledge sharing serves as an approach for PTT Group to deploy and apply as appropriate with respective own companies. In this regard, PTT has managed generated waste disposals for relevant waste according to the standards and laws set forth.

Waste generated from upstream petroleum & gas operations

PTT operates the petroleum exploration and production business and supplies this raw material to other businesses under PTT Group. Waste generated during the process of petroleum exploration and production and drilling cutting waste is  properly disposed per legal requirements and international standards. In addition, the company has been carrying out a study on upcycling drilling cutting waste for alternative construction materials , in accordance with circular economy principles. The mentioned process is currently undergoing research development.

Non-hazardous waste 

PTT emphasizes the waste separation process in office settings and therefore has prepared waste separation bins, including organic bins, general bins, recycling bins, etc. Furthermore, PTT disseminates knowledge with an emphasis on raising awareness and comprehension among employees regarding waste reduction, including waste sorting, through a variety of channels both via the website and the publication The aforementioned campaign activities have been organized in all operating areas throughout the country. In 2020, PTT Group treats facial mask separation and disposal as of great importance in order to prevent COVID-19 from spreading among staff. Furthermore, PTT Group has joined the ‘Vibhavadi Zero Waste’ campaign, organized by the Office of The Securities and Exchange Commission in collaboration with Thailand Responsible Business Network (TRBN). The campaign aims at private companies situated along Vibhavadi road to join hands in developing effective waste management, increasing recycling rates and reducing waste disposal.

Waste generated from PTT Group’s product consumption

PTT Group’s core products include petroleum, natural gas and petrochemicals such as plastic. The Group is determined to take as much plastic waste for recycling so that PTT and PTTOR have signed in an MOU for developing the recycling process of plastic waste from Café Amazon for reuse in its pilot project. The program requires research and studies to develop a prototype container for café Amazon’s plastic litters by applying QR code technology that enable the separation of plastic cups to facilitate waste collection for the Tumbler Upcycling process. In 2021, these waste containers installed at offices in Energy Complex Building enabled the collection of over 3,250 PET plastic cups. This amount can upcycle up to 601 Tumblers whereas 51.1 kilograms of plastic waste can be reduced which is equivalent to a reduction of 52.7 kilograms carbon dioxide equivalent (CO2eq) of greenhouse gas emission.
