Wow, "However, pyrolysing the SCG at 350 °C led to a significant improvement in its material properties, which resulted in a 29.3% enhancement in the compressive strength of the composite concrete blended with coffee biochar." pyrolysing: make or become decomposed through heating to a high temperature. "one solution is to pyrolyze the waste" SCG:Spent Coffee Grounds Might have to give it try. (Need to read more than the abstract though.)
