We have carried out the demolition of an old residential building in Gabriel Aresti Street in Leioa (Bizkaia). The selective demolition of the structure has been carried out in two consecutive days, in coordination with the City Council of Leioa and the Transport Consortium of Bizkaia, as its location is near the metro line L1 Plentzia-Etxebarri. In addition, coordination with other sectorial administrations has been necessary.
The remains of concrete and ceramic material from the demolition have been transformed into recycled aggregate, which will be used for various purposes in the future urban regeneration of the area.
This demolition project has served on the one hand to characterize various samples of demolition material in the framework of the INCARAD project, framed within the Projects of Aid to Circular Eco-innovation promoted by IHOBE – Environmental Agency of the Basque Government, and also as a pilot demonstrator of the digital tool BIM4DW, a software tool that helps the technician in the preliminary study of a selective demolition project, within the ICEBERG project.
The construction ecosystem in the EU represents around 10% of the GDP in the Eurozone, employing 25 million people in 5 million companies. Buildings, on the other hand, are directly or indirectly responsible for 50% of the extraction and consumption of natural resources, and account for more than 30% of the EU’s annual waste. They also account for more than 40% of global energy consumption and are responsible for 36% of GHG emissions.
In order to develop and demonstrate new circular solutions along the entire value chain, the ICEBERG project was created to recover secondary raw materials for the construction sector from CDW in a more efficient way. ICEBERG aims to design, develop, demonstrate and validate advanced technologies for the production of high purity secondary materials through 6 case studies throughout Europe. In this project, led by Tecnalia, Viuda de Sainz is collaborating by providing its experience in the handling and treatment of CDW.
