The Reinosa Steel Plant’s goal is to maximize our resource value while minimizing our environmental impact. This allows our operations, economy, community, and environment to thrive as we succeed. To achieve energy & recycling goals, the Reinosa Steel Plant:


  • Operates a state-of-the-art smoke extraction and purification system to reduce CO2 emissions and capture dust and particles generated during steel manufacturing; this filtered material is kept out of landfills and recycled as a raw material byproduct used by the zinc recovery industry
  • Reduces CO2 production by reducing emissions in heat-treatment processes


  • Maintains separate circuits of direct cooling water (dirty) from indirect (clean) and uses semi-closed cooling circuits to recycle 100% of all process water
  • Ensures all discharged water receives proper treatment for optimization and purification before it is released into the environment


  • Uses scrap as principle raw material to reduce energy required for production and CO2 emissions; each year the Reinosa Steel Plant recycles more than 100,000 tons of iron scrap
  • Scrap items no longer needed by the community are transformed into new commercial steel products; this recycles industrial waste and results in overall landfill waste reduction
  • Recycles reclaimed molding sand from the casting process to avoid waste and consuming natural resources
  • Uses steel-slag recycling in industrial raw materials
  • Recycles operational scale in partnership with the cement industry, as washing machine weights, and in internal recycling in the fusion process
  • Recycles refractory material in partnership with the mineral industry
  • Continuously and actively identifies all waste recycling opportunities in our steel production processes


  • Implemented an Energy Management System (in accordance to ISO 50.001:2011) to ensure ongoing, continuous improvement of energy performance; this includes establishing and reviewing measurable objectives in energy performance and incorporating energy efficiency as part of our best practices
  • Controls acoustic and atmospheric emissions, discharges, production, and storage of hazardous materials
  • Develops research partnerships with regional universities and Cantabrian industries to advance energy and recycling operations and opportunities
  • Optimizes operations such as renewal of hardening pit: these new systems resulted in reduction in the energy consumption in the plant in direct (process equipment) as well as indirect (related to reprocessing reduction due to hardening defects) consumption; thus, annual heat savings of 701,389.67 kWh NG could be achieved, as well as annual electricity savings of 4,271 kWh.
