Resumo

The urgency of positive action in the fight against climate change and for more sustainable production has led Vallourec to renew its energy matrix by bringing in renewable charcoal waste for use in its pellet plant in Brazil. As part of an initiative supported by UN through UNDP and the Sustainable Steelmaking Project, Vallourec was a global pioneer in using charcoal as the main fuel in its iron ore pellet heat treatment furnaces. This paper reports and updates information on Vallourec's initiative, which successfully reduced emissions from iron ore pellet production at the Jeceaba-MG pellet plant in Brazil by 23,894 metric tons of CO2e during the UNDP monitoring period (2018-2019) and by more than 200,000 metric tons of CO2e overall, considering the start of implementation in January 2017 through the end of 2021. The improvement also brought a significant reduction in operating costs, resulting in a payback of the total investment in only 18 months.
