Now they have stepped up a notch further and touched upon one more waste byproduct, coffee waste, that can become a valuable resource used as a part of a circular economy. To make concrete, it’s necessary to mix sand and … Continue reading How Australia’s RMIT University Plans to Turn 75 Million Kilograms of Coffee Waste into Durable Concrete
