Organic waste can't be added directly to concrete because it would decompose over time and weaken the building material. To overcome this challenge, researchers developed a technique to make concrete 30% stronger using coffee biochar made with a low-energy process without oxygen.
Freshly brewed coffee concrete may be coming to a street near you after RMIT University and Macedon Shire Ranges Council's world-first trial.
Several other upcoming infrastructure projects around Victoria, Australia, will also turn spent coffee grounds into biochar and transform this waste into a valuable resource for the construction industry. To overcome this challenge, the team has developed a technique to make concrete 30% stronger by using coffee biochar made with a low-energy process without oxygen at 350 degrees Celsius, to give the drink-additive a “double shot” at life and reduce waste going to landfill. “We are currently working in the supply chain sector so that we can make this research into a mainstream product for commercial applications, and we’re not only looking into coffee – we're expanding this into all forms of different organic waste,” Roychand said.
