DescriptionA company within the Campezo Group dedicated to the valorisation of black steel slag in Gipuzkoa. It processes this steelmaking by-product to obtain steel slag aggregate suitable for pavements, road layers and concretes, replacing natural quarry aggregate and preventing the slag from ending up in landfill. It is an example of circular economy between the Basque steel industry and the construction sector. Specific environmental documentation for the aggregate is pending verification.
