Background
The AZA Colina steel plant is a project of AZA Acero Sostenible, a Chilean company originally founded as Metalúrgicas AZA in 1953.[1] AZA began producing steel from scrap at its original plant in Renca, Chile in the 1960s.[1]
In 1992, AZA was acquired by Brazilian steelmaker Gerdau, and in 1999 the company inaugurated its Colina steel plant, with an initial production capacity of 360,000 tpa (tonnes per annum).[1]
In June 2018, Gerdau sold its entire stake in AZA to a consortium formed by four Chilean investors: Ingeniería e Inversiones Limitada, Inversiones Reyosan SpA, Los Andes S.A. de Inversiones, and Matco Cables SpA.[2][3]
The AZA plant currently has an annual production capacity of 520,000 tonnes of crude steel.[4] Billets produced in Colina are transformed into long steel products including bars, wire rod and profiles at Colina's rolling mill and at AZA's original plant in Renca.[4][5] The Colina and Renca rolling mills have steel processing capacities of 370,000 and 100,000 tpa, respectively.[4]
AZA promotes itself as a "green steel" producer, based on its commitment to the SBT (Science Based Targets) initiative for lowering greenhouse gas emissions, the company's recent successes in reducing CO2 emissions to less than 0.5 tonnes for every tonne of steel produced, and the certification of its energy management system under the ISO 50001 standard.[4]
