‘Reusing materials is one of the most direct ways to reduce carbon emissions,’ says Josse Popma, cofounder of Popma ter Steege Architecten (PTSA). But, as material transparency becomes paramount, perhaps the question is not only whether materials are being reused, but also where they come from. Interestingly, many architecture practices such as PTSA are now taking a hyperlocal approach to material reuse by ‘mining’ materials from the sites they’re working on. Rather than collecting salvaged materials from distant sources, they’re reusing what’s right in front of them, reducing waste while minimizing transport emissions, and fostering a deeper connection among designers, craftspeople and the existing environment. While there are clear benefits to this site-specific approach, there are also challenges, such as increased project risk and potential management issues. So, should architects…
