HOLCIM X ELEMENTAL

Biography

Swiss building materials company Holcim and Chilean architectural firm Elemental, headed by Pritzker Prize winner Alejandro Aravena, unveiled a highly sustainable building prototype at the Venice Architecture Biennale 2025. At its core lies a zero-emission biochar concrete made from organic waste and mixed with recycled cement and aggregates to offer a low-carbon, high-performance solution for the construction industry. “This new technology for decarbonising materials allows us to respond quickly and with precision to the serious housing crisis that Latin American countries in particular are experiencing while also offering a very eco-friendly alternative”, Aravena explains.
