Caring for the Planet Press Metal Aluminium Holdings Berhad SECTION 5 • DELIVERING SUSTAINABLE VALUE FOR OUR STAKEHOLDERS 158 A comprehensive approach to waste management has been embedded across operations, focusing on reduction, reuse, recycling, and recovery initiatives. These efforts are designed to optimise resource efficiency, minimise environmental impact, and align with regulatory requirements. Recovering Aluminium By-Products The integration of recovery processes within aluminium production is essential to minimising environmental impacts associated with aluminium by-products. Valuable materials from aluminium and carbon dross, such as aluminium and electrolytes, can be efficiently reclaimed and reused. By recovering by-products, we are able to significantly reduce waste and mitigate the risk of harmful substances entering the environment while conserving natural resources through reduced reliance on virgin materials. The Aluminium Dross Recovery Unit is assigned to oversee the internal recovery of aluminium dross at cast houses, ensuring an efficient process where aluminium is reclaimed and remelted into new products. The residual materials generated are securely packaged and transported to licensed aluminium recyclers for further recovery process. In FYE2024, dross recovery capabilities were enhanced through the installation of a dross stirrer machine at PMS and the upgraded Iron Dross Treatment Plant and Carbon Dust Recovery System at PMBtu. These advancements further strengthened resource recovery efforts and reduced environmental impact. Furthermore, the internal carbon dross recovery process facilitated the reclamation of electrolytes for reuse in the electrolysis process, leading to a reduction in hazardous waste, particularly carbon powder. Repurposing Spent Pot Lining As part of ongoing safety enhancements and efforts to improve operational efficiency, electrolysis cells are maintained periodically. This process generates SPL, a hazardous waste that contains sodium, fluoride and other heavy metals, which — if not properly managed — can pose environmental risks. The facilities’ EHS department oversees the secure handling and storage of SPL to mitigate potential environmental impact. In line with efforts to reduce landfill dependency, Press Metal has established a strategic collaboration with cement manufacturers to repurpose SPL as an alternative raw material in cement production — converting a hazardous waste stream into a viable industrial input. Efforts are underway to explore alternative management methods that optimise the utilisation and disposal of SPL, reinforcing a commitment to sustainable waste management practices within the industry. Coaction for Full Recovery Plant Expanding on our commitment to the 4R approach, collaboration continued with a licensed waste recovery company to enhance the full recovery plant in Bintulu, Sarawak. This facility plays an important role in recovering aluminium dross and scrap, significantly reducing landfill waste and optimising resource efficiency. Ongoing initiatives focus on refining recovery processes, integrating advanced technologies and identifying circular solutions to maximise material reutilisation. These efforts support long-term sustainability objectives while reinforcing responsible resource management across operations. Zero-Waste Factory In 2024, PMI was acknowledged as a pioneer in Foshan’s “Zero-Waste City Cells” initiative and conferred the designation of a “Zero-Waste Factory”. The recognition reflects PMI’s implementation of circular waste management practices, including the reprocessing of production waste into usable materials, thereby reducing overall waste generation. This initiative aligns with Foshan’s broader objective of establishing itself as a leading Zero-Waste City. Implementing E-Waste Recycling In collaboration with ERTH, Malaysia’s largest authorised e-waste collector, Press Metal promotes responsible electronic waste disposal through targeted recycling programmes. In supporting proper e-waste management, collection boxes had been strategically placed at the corporate headquarters in Setia Alam, Selangor. Additionally, other entities within the Group also had established dedicated collection points for specific e-waste items, such as used batteries, further expanding our responsible electronic waste disposal initiative. These initiatives provided employees and the public with a convenient and responsible solution for e-waste disposal, reducing environmental impact. In FYE2024, the e-waste recycling programme successfully diverted 460 kg of discarded electrical items from disposal, including small household appliances, laptops, smartphones, CPUs, monitors, and keyboards.
