Resource management and the integration of circular economy principles are key pillars of METLEN's sustainable development strategy. With the aim of rationalising the use of natural resources and minimising its environmental footprint, emphasis is placed on the production of recycled aluminium, which is at the heart of the circular economy. At the same time, METLEN participates in research projects for the exploitation of bauxite residues for the extraction of rare earths. further strengthening its resource-efficient initiatives. In addition, the Company's waste management is based on best practices, promoting the recycling and reuse of materials, with the ultimate goal of gradually transitioning to a circular production model that contributes to sustainable development. According to the 2025 Double Essentiality Assessment, significant impacts related to the above challenge are:

METLEN has established a comprehensive governance framework for the management of sustainability issues, which is integrated into the Company's core decision-making and oversight processes. The role of the Management is clearly defined and ensures continuous supervision and strategic guidance on sustainability issues.
In particular, the Sustainable Development Committee, as a committee of the Board of Directors, is responsible for monitoring the implementation of the sustainable development strategy, approving relevant policies and monitoring the Company's ESG performance. The Committee meets regularly and cooperates with the Directorate-General for Corporate Governance and Sustainable Development, which plays a crucial role in coordinating all sustainability issues within the Company. The governance of sustainability issues is supported by specially defined organisational structures, which include teams and sustainability officers in each Business Sector and a key subsidiary. ESG thematic pillar managers work with central and local management teams, ensuring coordination, monitoring progress and providing technical guidance, with the aim of systematically integrating the principles of sustainable development across the Company's range of activities.
At the same time, METLEN applies a systematic due diligence approach to manage actual and potential significant sustainability impacts, risks and opportunities. This approach is based on the international guidelines for responsible business conduct and includes: identification and impact assessment processes, setting targets, action plans, monitoring mechanisms, taking corrective actions, consulting stakeholders and promoting value chain partnerships.
Through these mechanisms, METLEN ensures that sustainability issues are integrated into its business strategy and day-to-day operation, enhancing long-term value creation for all stakeholders.

METLEN integrates the principles of circular economy and efficient resource use into its sustainable development strategy, aiming to reduce its environmental footprint and optimise the utilisation of raw materials and secondary materials.
The Group implements procedures for the identification and assessment of impacts, risks and opportunities related to resource use and circular economy through:
At the same time, METLEN implements policies that promote the recycling and reuse of materials, advancing circular economy solutions across critical material flows and enhancing the use of secondary raw materials within the production process.
The Group utilises environmental performance indicators (KPIs), waste utilisation indicators and recycling rates to monitor the effectiveness of relevant actions, while also assessing opportunities related to:

METLEN implements actions that support the transition towards a more circular and resource-efficient production model, with a focus on waste reduction, the utilisation of secondary materials and the enhancement of recycling practices. The Group promotes the use of recycled aluminium and secondary raw materials within the production process, while investing in the development of new circular metallurgy activities and the recovery of valuable materials.
In this context, METLEN operates the EPALME plant for the recycling of aluminium scrap and the production of secondary aluminium, while also developing a new recycling facility for copper and zinc waste and participating in research projects for the recovery of valuable raw materials from bauxite residues.
In 2025, secondary aluminium production reached 56,751 tonnes, recording an increase compared to 2024, as part of the target to produce 100,000 tonnes by 2030.
At the same time, 94.3% of the materials used for the production of secondary aluminium originated from recycled aluminium scrap, while more than 58,000 tonnes of recycled materials were used overall in the production process.
In addition, the Group recovered and utilised more than 176,000 tonnes of non-hazardous waste through recycling and recovery processes, while approximately 73.6 thousand tonnes of bauxite residues and bauxite steriles were supplied to cement industries and other industrial applications as alternative raw materials, further supporting the implementation of circular economy practices.
