Abstract
Introduction. Aceros Industriales S.A. is a company founded in 1977 and works on transforming
in cold ferrous and non-ferrous materials (tefilation). They used, from the beginning of
the company, the chemical stripping process, due to the fact that in that time it was the only
technology available. Methodology. In 2005 Aceros Industriales S.A. makes the decision of getting a world level
concerning its technology, by changing its productive system and acquiring equipments for shot
blasting and decalamination of brushes, thus eliminating the chemical stripping.
Results. By the mechanical stripping process, a decrease of environmental damage was achieved
(diminishing in DQO and mud generation, among others), a better performance of the
industrial process, the incorporation of industrial incomes diminished, maintenance and operation
of the shot blasting and decalamination units got easier and a saving rate of 86 million of
Colombian Pesos was achieved.
Conclusion. This situation showed us that cleaner production opportunities are very important
for the metal processing industries.
