Coffee concrete hopes to create sustainable building material out of ‘organic waste’

RMIT’s Dr Rajeev Roychand explains the world’s first coffee concrete footpath has been laid in Australia marking a significant milestone in the quest for sustainable construction practices. “We started this research about two years ago because we are focusing on the large amount of organic waste that ends up in landfills, which is about 6.78 million tons per year and is responsible for about three per cent of Australian greenhouse gas emissions,” Dr Roychand told Sky News Australia. “This discussion started with a cup of coffee, and there where we decided why not start with coffee itself.”
