Sustainability and ASI at CBA

Why ASI?

ASI (Aluminum Stewardship Initiative) stems from the joint commitment of aluminum value chain’s stakeholders to broaden the industry’s stake towards a more sustainable society.

The ASI Certification Program assesses all stages of the aluminum value chain, from bauxite mining to the manufacturing of final products, with the aim of accrediting those companies that produce aluminum in a socially and environmentally responsible fashion.

The entity then assesses the company's management principles around three pillars of Governance, Environmental and Social issues.

  • Under the Governance pillar, the assessment covers business integrity, corporate policies, transparency and process/product management;

  • Within the Environment pillar, matters such as greenhouse gas emissions, environmental emissions, effluents and waste, water management and biodiversity are assessed.

  • In the Social pillar, aspects of human rights, labor relations and occupational health and safety are considered.

The journey to earn the ASI certification began in 2017, when we joined the institution.
In 2018, a comprehensive in-house assessment of our management and production system was carried out, aligning our practices with those of ASI.

Right in our first audit, we earned the Performance Standard certification showing high standing of readiness tackling the ASI guidelines.

Sustainability at CBA

Our sustainability strategy builds on four megatrends that will influence companies over the next few years and pose significant business challenges for decades to come. They are: the Planet under pressure, hyper transparency in relations, a diversified energy matrix and change in the production pattern.

From these megatrends, #ourCBA has set out eight strategic themes for achieving the long-term goals of our operations, which we have converted into initiatives and milestones with a resolution deadline set for until 2025.

Thus, seeking an operation that matches with such commitment, we have put solutions in place that are a substantial move in ensuring that are our processes in it are sustainable. Here are some of them:

  • Dry disposal via press filter installation at the aluminum waste dam, a project that will eliminate the disposal of sludge waste, extend the reservoir life and allow recovering and reusing water and raw materials stemmed from the bauxite refining process;

  • The Green Soderberg project that is aimed to drop air emissions and water consumption for gas treatment, making our aluminum even more competitive environment-wise;

  • Sustainable Mining - Since 2008, we have devised a model of soil rehabilitation and biodiversity preservation. Jointly with universities, we have kicked off new practices to better fit the environmental rehabilitation processes of mined areas, and enable them to reintegrate into the region's landscape under conditions that are even better than those prior to mining.
