Waste Management

Efficient Use of Resources

Waste Management

We continually seek smart alternatives to reduce, reuse, and recover the waste we generate in our operations. To this end, we identify opportunities throughout the entire production process, develop innovative products, and seek new markets with the help of our R&D+i department and in collaboration with users, universities, and technology centers.

Final Destination of Waste

Serious goals and challenges

To recover 90% of waste by 2025 and 95% by 2030

Waste recovery rate (%)

Advances in Circularity

To achieve our recovery goals, we have developed short- and medium-term lines of work with four main areas of action.

Generation Reduction

The reuse of refractory bricks used in different steelmaking processes has made it possible to reduce their generation by more than 250,000 kg/year.

Improved processes for identifying and segregating waste from cleaning the scrap yard have allowed us to recover more than 2,000 tonnes of ferrous waste.

Increased Recovery

The search for recovery alternatives for the waste we generate has allowed us to reduce the waste sent to landfills by up to 8% in the last year.

We have disposed of 3,200 tonnes of black stainless steel slag.

Through operations to identify and segregate lime-rich waste streams, we have managed to recover more than 7,000 tonnes in the cement industry.

Byproduct Quality

The cooling and recovery processes for white and black stainless steel slag have been segregated, enabling the recovery of more than 3,000 tonnes.

Sidenor has approved an investment of over €12 million to improve the cooling and treatment processes for all its slag.

New Markets and Destinations

Thanks to all the efforts made to improve the quality of our byproducts in recent years, we have found new markets for:

  • 100% of the refractory material from tundishes that was intended for recovery in cement plants. It is currently recovered by manufacturing various eco-friendly refractory products.

  • Slag treatment with Harri Green will enable its recovery for higher value-added uses (bituminous mixtures and concrete).
