Energy and Emissions

  • Our processes make intensive use of energy, mainly electricity and natural gas
  • We envisage the implementation of initiatives for efficient and sustainable consumption
  • We strive to reduce our operations’ environmental impacts and atmospheric emissions to minimize our footprint

As part of the indirect emissions reduction strategy, we endeavor to use energy efficiently, while continuing the transition to a cleaner energy portfolio.

Other atmospheric emissions

Metallurgical processes are the primary sources of direct emissions, especially lead and sulfur dioxide. We implement emission reduction systems and permanent, real-time monitoring to ensure emissions are kept below the limits established in current regulations.
