“Both reports confirm our previous statements that there was no overflow from the bauxite residue deposit areas, as well as no indication or evidence of contamination to nearby local communities from Alunorte as a result of the heavy rainfall in February,” says President and CEO, Svein Richard Brandtzæg.

“We have initiated several measures to further enhance Alunorte’s operational standards, including water treatment capacity, emergency preparedness plans and maintenance. We will also strengthen community engagement to ensure that we contribute to sustainable development in Barcarena in line with Hydro’s CSR Strategy,” he says.

Following the unusually heavy rainfall in February, an internal task force and Brazilian environmental consultancy SGW Services have performed reviews of Alunorte. The reviews include the operation of the bauxite residue deposits, water and effluent systems, and potential impact on the external environment.

Main findings from the internal task force and SGW Services are the following:

  • No overflows from Alunorte’s bauxite residue deposit areas
  • No indication or evidence that Alunorte has contaminated local communities of Barcarena
  • No indication or evidence of any significant or lasting environmental impact to nearby rivers
  • Improvement proposals in the following areas:
    • Water management and treatment capacity
    • Preventive maintenance and upgrades
    • Emergency preparedness plans and training

Alunorte has already implemented or initiated a comprehensive list of short, medium and long-term actions, including the following measures:

  • Short-term improvements of the water management systems and treatment capacity, maintenance systems, as well as emergency preparedness plans and training
  • Investment of NOK 500 million (approx. BRL 200 million) in the refinery water treatment system, increasing treatment capacity by 50 percent and basin capacity in water treatment plant by 150 percent
  • Project to review and consider further strengthening of Alunorte’s water treatment system as a proactive response to possible future climate and weather changes
  • Development of sustainable closure concept for DRS 1
  • Update of emergency procedures, including review of the communication practices for local communities during and following emergencies. This will also include training for the communities nearby Alunorte
  • Third-party environmental study on quality of air, water, springs, soil and forest
  • Strengthening of local and central environmental resources and competence
  • Toxicological study to evaluate health conditions of people in the communities nearby Alunorte

Further, Hydro will implement additional measures to position Alunorte as the benchmark alumina refinery in the global aluminium industry:

Technical and environmental measures

  • Maintenance and equipment upgrade, including measures to address improvement potential identified in the reports
  • Increase number of water sampling wells at and around Alunorte’s premises for improved monitoring of the environment
  • Further strengthening of collection, testing, analysis and monitoring of environmental and health data, including water quality

Social measures

Hydro is in dialogue with relevant stakeholders, including the Government of Pará, to strengthen community engagement, contributing to sustainable growth in Barcarena.

In parallel, to support broad collaboration for social change in Barcarena, Alunorte will commit around NOK 250 million (BRL 100 million) in local community investments through a new initiative, the Sustainable Barcarena Initiative:

  • Separate legal entity, with its own organization, staff and mandate, financed by but independent to Alunorte
  • The initiative will provide capacity building, establish a public platform for data monitoring and evaluation, develop social and environmental projects
  • Alunorte will act in partnership with communities, academia, authorities, unions and relevant organizations

In addition to the Sustainable Barcarena Initiative, Alunorte has committed to maintain access to clean water in Burajuba, Bom Futuro, and Vila Nova. In the short-term, the company is providing medical assistance and water distribution to 1,800 families in local communities. Alunorte is also engaging with the communities to develop and implement short-term social projects.

“Our clear ambition is to make Alunorte the benchmark in our industry, ensuring sustainable operations and social change in the communities around us,” Brandtzæg says.

Alunorte is the world’s largest alumina refinery, with around 2,000 direct employees and an annual nameplate capacity of 6.3 million tonnes. Hydro owns 92.1 percent of Alunorte.
