                     The first-ever coffee concrete sidewalk is now being put to the test

     We regularly report on potentially industry-changing developments in the materials space, but it’s not often that we see them put to practical use. RMIT has partnered with a local Victorian government council, the Macedon Ranges Shire Council, to lay organic waste-enhanced concrete sidewalks (or 'footpaths' as they're called Down Under) in a world-first trial. Two types of concretes – one made with coffee biochar and one with wood chip biochar – were laid alongside standard concrete, which will act as a control.
    “We’re taking those experiments and putting them in ground and in the field today, we’re going to have people walking across the concrete that includes these products, and RMIT is going to be coming back and doing testing to see how they stand up,” said Shane Walden, the Council’s Director of Assets and Operations. “This not only helps improve the knowledge level of our contractors and our staff, but it also has lots of other benefits and benefits that are important to our community. This includes helping the environment, acting sustainably and, most importantly, reducing waste to landfill and having a circular economy.”
“We are currently working in the supply chain sector so that we can make this product 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,” said Rajeev Roychand, from RMIT’s School of Engineering. “Every biochar produced from a different organic material comes with varying composition, in addition to the difference in carbon content, particle size and absorbency, that can boost the performance of concrete in a range of ways.”
