Delivering Sustainable Value For Our Stakeholders Delivering Sustainable Value For Our Stakeholders Press Metal Aluminium Holdings Berhad 142 143 Integrated Annual Report 2023 Caring for the Planet Typically, water employed for cooling is recycled within our closed-loop water system. Any wastewater generated undergoes treatment via a water treatment system to meet discharge quality standards set by relevant regulatory bodies before being discharged into the environment. Each year, we conduct water risk assessments, utilising tools such as the WWF Water Risk Filter and the World Resource Institute Aqueduct Water Risk Atlas, to pinpoint potential water risks within our operational areas. While we do not have any operations in water-stressed regions, our commitment to safeguarding water resources remains resolute. To this end, we continuously strive for optimal water usage efficiency across all our operations.

Implementing Water Conservation Practices We have implemented rainwater harvesting systems for irrigation and cleaning purposes, thereby reducing our dependence on municipal water sources. Additionally, we have installed flowmeters at strategic points to monitor daily water withdrawal and detect any abnormal water consumption. As part of routine maintenance, we maintain the cooling towers regularly for optimal operations and perform necessary upgrades to our wastewater treatment facilities to enhance recycling and efficiency rates. Optimising Water Consumption The initiation of the Water Balance Project enables us to conduct comprehensive monitoring on consumption as well as abnormalities due to water leakages. Additionally, we optimise water consumption at PMI and PMIT for firefighting and production needs through a surveillance programme. Water employed for treating aluminium products at the anodising tanks will be channeled to wastewater treatment facilities prior to being discharged. As part of water stewardship efforts, we reuse water from plate cooling at anodising tanks and rechannel the overflow water from anodising tanks into rinsing tanks, for reuse in the treatment process. Additionally, we utilise greywater for polymer dilution, cleaning filters and floors, further enhancing our water stewardship efforts. Improving Our Wastewater Treatment Plant Our wastewater treatment facilities at our extrusion facilities are designed to treat industrial effluents, particularly those generated from anodising process. To further enhance our wastewater treatment, modifications and improvements were made at the PMBA Wastewater Treatment Plant (“WWTP”) to boost efficiency and effectiveness, including the addition of an equalisation tank, automation of the reaction tank, changing of circular clarifier, and upgrading of the filter press to better process the wastewater. Our team is constantly researching ways to improve the dewatering process by testing various filter cloths for efficient filtration process and ultimately, enhance the performance of filter press system in reducing the water content of the sludge cake. Caring for the Planet WATER AND EFFLUENTS GRI 3-3, GRI 303-1, GRI 303-2, GRI 303-3, GRI 303-4, GRI 303-5 M12 WHY IT MATTERS Water is a shared and crucial resource that is vital for the communities where we operate. Despite its renewable nature, many regions face water scarcity due to factors like climate change, poor water resource management and contamination. This highlights the need for responsible water management practices by businesses, including continuous monitoring of water usage and implementing strategies to increase efficiency. In doing so, we can positively impact local communities, mitigate operational disruptions and lower costs. UN SDGs Capitals MC OUR APPROACH Recognising that water is a shared resource, we have proactively embraced responsible water resource management practices across our operations. This commitment involves implementing effective strategies for monitoring water withdrawal, consumption and discharge. Our commitment is outlined in our Sustainability Policy, Environmental Policy and Environmental Mission Statement, all accessible at: https://www.pressmetal.com/investor-relations/corporate-governance.php. Press Metal has set water withdrawal intensity targets where we aim to achieve 5% and 10% reductions by 2023 and 2030, respectively, from year 2016 baseline*. Water operations at our various entities are administered by their respective water departments. Additionally, our China operations have established a Water and Energy Conservation Working Group to oversee their water management efforts. Guided by our commitment to responsible water consumption, we strive to preserve the quality of surrounding water bodies at the locations where we operate. To achieve this, we have adopted a Water Management Plan in managing our water impact: * 2016 baseline: 3.1m3/ tonne of aluminium • Minimising freshwater consumption through maximised water reuse • Applying the 3R (Reduce, Reuse and Recycle) approach to conserve water • Minimising freshwater consumption through water recycling efforts • Maintaining zero (0) contamination of surface water, groundwater and other water resources • Monitoring our performance against water reduction targets • Adhering to national, regional and local regulations for water quality Our Water Management Plan guides effective water utilisation through established action plans, encompassing facility enhancements, process optimisations, monitoring, inspections and educational initiatives throughout our manufacturing facilities to optimise water efficiency and identify areas for improvement. Monitoring and Assessing Water Withdrawal, Usage and Discharge Maintaining a vigilant approach to our water supply and consumption is important. Our water primarily originates from municipal potable sources, with no direct extraction from natural water bodies like rivers, oceans, surface water or wells, excluding rainwater harvesting. Water is mainly used for domestic and cooling purposes within our midstream facilities and treatment of aluminium profiles in downstream facilities. NC
