Why It Matters
As a chemicals manufacturer, our business relies on energy, water and minerals.
This is why preventing environmental pollution is crucial, especially within the local communities where we operate. It’s why we aspire to grow responsibly by protecting biodiversity to mitigate any harm on local ecological systems.
Through environmental stewardship, we recognise the physical climate-related risks such as water availability which can directly impact our operations. Employing best practices in managing our environmental footprint will enable us to contribute to the relevant United Nations Sustainable Development Goals (SDGs) while complying with local regulatory requirements and recognised industry standards.
Our Approach
- We adhere to all applicable environmental regulations in the areas where we operate and remain guided by environmental standards which we subscribe to. Nearly all of our operations have attained ISO 14001:2015 certifications, reflecting our credibility, high standards and commitment to environmental management systems.
- We are also advancing towards digitalising our business operations to reduce the consumption of paper and waste generation.
- We continue to be guided by our Health, Safety and Environment (HSE) policy, as well as the PETRONAS Mandatory Control Framework and Technical Standards, which provide guidelines and best practices to achieve optimal management of our water, waste and air emissions.
- Going beyond compliance, we have adopted the Circular Economy approach to strengthen our environmental stewardship. This involves transforming waste generated from our facilities — including air emissions, discharges and hazardous/non-hazardous waste — into resources, or repurposing them to keep it out of landfills, which emit methane that’s harmful to the surrounding natural environment.
How We Provide Value
01
Water and Wastewater Management
- We strive for efficient water consumption and wastewater management throughout our processes at our facilities.
- We are governed by PETRONAS Technical Standards (PTS) on wastewater management, local regulatory standards and other relevant frameworks that provide guidance on conserving water resources.
- We closely monitor water availability in water-stressed regions. Water stress has been identified as a critical physical climate risk that might impact our operations and the surrounding community where we operate.

Waste Management
- We are guided by the PTS on hazardous waste management and established our Waste Minimisation Blueprint as an overall guide that promotes the 3R’s (Reduce, Reuse and Recycle) for hazardous waste.
- As a chemical company, we convert raw material and natural resources into products and solutions that help to enhance the quality of life and support the transition to a low-carbon economy.
- Our use of non-renewable raw materials, including precious metals and chemicals as a catalyst for certain processes, has the potential to increase waste generation and depletion of finite resources. However, this is mitigated via enhancing recycling practices within our operations..

Air Emissions
- We implemented an air emissions monitoring programme, where we monitor the emissions levels surrounding our facilities and in nearby communities, as we strive to minimise air pollution levels in line with the Malaysian Ambient Air Quality Standard.

Biodiversity
- We are guided by PETRONAS’ position on Nature and Biodiversity and the PETRONAS Technical Guideline on Biodiversity and Ecosystem Services (BES) Management, which specifies identification and mitigation measures.
Our focus is on activities aimed at conserving and rehabilitating ecosystems and habitats. - ecocare, our signature environmental conservation initiative launched in 2005, involves reforestation of the ecologically sensitive mangrove habitat along Sungai Kertih in Terengganu. Over the years, ecocare has evolved to include the ecoCare Environmental Education Centre (EEC), a resource centre that promotes awareness and understanding of environmental conservation among teachers, students and community.
