Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a "double shot" at life and reduce waste going to landfills. [...]
Published in the Journal of Cleaner Production, the study by RMIT engineers is the first to prove that waste coffee grounds can be used to improve concrete.
— Science Daily
The study found that three different coffee ground samples each increased their concrete pour’s compressive strengths by up to 30% once their organic compounds were broken down through pyrolysis. The discovery could go a long way in combatting issues such as food waste and the carbon impact of... View full entry
Engineers at RMIT University have developed a method to use disposable personal protective equipment (PPE) to make concrete stronger, providing an innovative way to significantly reduce pandemic-generated waste. [...]
Joint lead author, Dr Rajeev Roychand, said there was real potential for construction industries around the world to play a significant role in transforming this waste into a valuable resource.
— Science Daily
According to the RMIT researchers, an incredible 54,000 tons of PPE waste has been produced daily since the start of the pandemic. "With a circular economy approach, we could keep that waste out of landfill while squeezing the full value out of these materials to create better products &mdash... View full entry
