For Gerdau, one of the largest long steel producers in the world, Nathan conducted study to estimate the availability and use of ferrous scrap, a vital raw material for new steel production in three countries, i.e., Peru, Mexico and Argentina.

A time series of historical scrap volumes was developed along with econometric models to predict annual available ferrous scrap volumes, which Gerdau uses to take a decision on whether to extend its operations in the country.
