BRAZIL - CONSUMPTION IN 2025 - NEXA RESOURCES
A significant share of global zinc consumption is linked to galvanization, which supports key sectors such as construction, infrastructure, mobility and energy, Rodrigo Cammarosano, head of investor relations and treasury at Nexa Resources said.
He highlighted that zinc also has growing applications in renewable energy generation, where galvanized structures play a relevant role.
He noted that zinc’s relevance comes from its ability to protect steel components and extend the durability of large-scale projects.
He said that solar and wind installations rely heavily on galvanized steel.
He also highlighted emerging uses of zinc in new metallic alloys and stationary energy-storage technologies.
Brazil’s zinc demand has been supported mainly by galvanization, with construction, infrastructure, energy and mobility remaining the core downstream sectors, according to Cammarosano.
“The consumption of galvanized steel in Brazil has been pressured by a more challenging macroeconomic environment, including higher interest rates,” he said, adding that rising imports of galvanized steel and finished goods containing galvanized components have also affected perceived domestic demand.
Even so, structural drivers linked to construction and infrastructure continue to play a central role.
Nexa’s operations and carbon-intensity efforts : Nexa operates an integrated zinc chain in Latin America, combining its mining operations with downstream smelting capacity to supply customers across the region. This structure gives the company visibility over both concentrate availability and refined metal demand.
“With our current level of integration around 50–55%, and the potential to reach 60–65% once Aripuanã is at full capacity and our life-extension project at Pasco is in place, we will be able to capture even more value from this structure, resulting in a more resilient model overall,” Cammarosano said.
He also referred to decarbonization efforts, highlighting a power mix that relies mainly on renewable energy sources.
The company has equity stakes in hydro and small hydropower plants and long-term renewable contracts for Cajamarquilla, Peru.
“Zinc produced at Cajamarquilla has a carbon intensity of around 0.78 tonnes of CO2 equivalent per tonne of zinc, compared with a global average of about 3.5 tonnes,” Cammarosano said.
“At Três Marias, the intensity is around 1.5 tonnes per tonne of zinc, which is less than half the global average, according to data from the International Zinc Association,” he added.
