From reducing emissions and transitioning to renewable energy sources to improving waste management practices, these are some of the initiatives that reflect Tenaris’s commitment to creating a cleaner, safer, and more sustainable future.
RomaniaTenarisSilcotub just launched its first 20 MW solar park in Călărași, that will provide 8% of the electricity consumption of the site. Generation would be equivalent to powering about 10,000 homes every year.
This is a big step towards using more renewable energy and making Tenaris’s steel production process more sustainable.

ArgentinaTenaris is making big strides in its energy transition with the construction of its second wind farm in Olavarría, Argentina. La Rinconada Wind Farm will have 21 turbines and, once complete, will generate 448 GWh of renewable energy annually: enough to provide 30% of the electricity consumption of the site. Together with the Buena Ventura Wind Farm, Tenaris’s first wind farm already in operation since 2023, they are both significantly reducing TenarisSiderca’s emissions and contributing to the achievement of Tenaris’s global reduction target.

The Canadian team has installed a new $1.2 million scraper at its Sault Ste. Marie plant to improve water treatment in the hot rolling mill. This is part of a $5 million investment plan to modernize the facility’s water management system. Second phase is already implemented allowing for better water management both for the operations on site and for the environment.
USATenarisKoppel installed a new $85 million baghouse for enhanced fumes treatment at its steel mill in Koppel, Pennsylvania. This system is part of a broader investment plan in the plant, to improve both environmental performance and production capacity.

ItalyTo reduce emissions from the expander rolling mill, TenarisDalmine is investing USD 5M in a new technology installing an electrostatic precipitator and filter. Set to begin operation this year, the new plant will contribute to better environmental performance supporting the facility's ongoing sustainability efforts.
ChinaTenarisQingdao’s first photovoltaic rooftop power generation system is operating with a capacity above 1 megawatt. The installation, which also includes energy storage, started operating in October 2023 and cuts emissions by around 1,000 tons per year—the equivalent of taking more than 200 cars off the road—while helping reduce energy costs at the plant.
ColombiaAs part of its decarbonization strategy, TenarisTuboCaribe has replaced a natural gas furnace with an electric induction coil on its Upsetting Line. The upgrade is expected to cut CO₂ emissions by 2,000 to 3,000 tons per year: roughly the amount 100,000 trees absorb annually. The switch also boosts energy efficiency and has lowered temperatures by 10°C in key areas of the line, creating a safer, more comfortable workspace for employees.

IndonesiaTenarisSPIJ has replaced its manual varnishing process with a new automated line that uses water-based coatings. This change significantly cuts emissions minimizing pollutants related to the varnishing process, while also reducing waste generated. It’s a more sustainable, safer solution: better for both people and the planet.
BrazilAt TenarisConfab, industrial waste is carefully sorted to maximize recycling and recovery, and today more than 90% of total generation is recycled and reused. In one year alone, over 8500 tons of different materials were sent to recycling or reuse including: hazardous waste treated replacing fossil fuels in cement production, wood, paper, etc. Non-recyclable waste is minimized and sent to landfill only as a last resort, but there are still opportunities to continue improving and to support circular economy while significantly reducing the environmental footprint of operations.

Saudi ArabiaAt TenarisSSP, a long-standing issue with coolant overflow from chip containers, especially during heavy rain, has been resolved through a coordinated effort across multiple teams. The solution includes minimizing residual coolant, civil works for secondary containment, and a special rainy-season protocol to prevent spills. The improvements help reduce environmental risk and ensure safer, more efficient operations.
MexicoTenaris is advancing its scrap management strategy in Veracruz, Mexico, with a $21 million investment over the 2023–2025 period and the paving of 60,000 m².
The goal: to maximize the use of scrap in steel production, continue improving charge to thousand, reduce reliance on mineral pig iron, and lower carbon intensity. The initiative also includes testing alternative raw materials with a smaller environmental footprint, such as bio pig iron.
