    Hydro announced that the company will invest R$5 million (USD 1.2 million/NOK 10.7 million) up to 2022 to study the reuse of bauxite residues, which takes place at Alunorte alumina refinery. The partnership between Alunorte and Senai Institute of Innovation in Mineral technologies (ISI-TM) could significantly reduce deposits of bauxite residues.

    The analyses will be performed in Senai's laboratories.

    Raphael Costa, director of technology in the Bauxite & Alumina business area said: "We wish to make Alunorte, the world's largest refinery outside of China, a global reference for reuse of bauxite residues, inspiring the entire segment of aluminium."

    "Products made from bauxite residue can contribute to reducing the consumption of non-renewable raw materials, reducing greenhouse gas emissions and preserving biodiversity."

    The agreement will evaluate the possibility of extracting iron from the bauxite residues for use in the steel industry, and how it can also be used for conditioning and soil pH control in agribusiness.

    "We have reinforced our commitment to the operational stability of the plant, with the pursuit of better environmental and social practices through continuous investment in technology, innovation and projects that provide sustainable development for our region. This agreement is another step in this direction," said Carlos Neves, Chief Operational Officer of Bauxite & Alumina.

    The partnership ranges from the physical, chemical and mineralogical characterization of bauxite residue to the elaboration of conceptual plan and executive project for the implementation of a pilot plant in the company, Hydro said.

    Adriano Lucheta, director of the Senai Institute for Innovation in Mineral Technologies said: "Through investment in innovation, we can apply the concepts of circular economics in mining and Alunorte is being the pioneer in Brazil. We are confident that it will also be a motivator for other extractive industries to enter into this new context."

    Globally, it is estimated that only 3% of the 150 million tonnes of residue produced annually are recycled. The aim of the agreement is to contribute to the global sustainability goal of the 25% reuse sector.
