Australian engineers have developed a method to enhance concrete strength by nearly 30% using biochar made from spent coffee grounds. This innovative approach, involving a low-energy pyrolysis process, not only strengthens concrete but also offers environmental benefits by reducing the need for natural sand in construction. The technique, still in early stages, could significantly decrease organic waste in landfills while preserving natural resources. This advancement in recycling coffee waste into construction materials marks a significant step towards sustainable construction practices.
