The article quotes them describing a range of biochar souce materials: > “Our research team has gained extensive experience in developing highly optimised biochars from different organic wastes, including wood biochar, food-waste biochar, agricultural waste biochar, and municipal solid-waste biochar, for concrete applications,” But it doesn't actually say anything about coffee biochar in comparison to any other biochar. Is this a setup to be a research mill where we'll get the same press release every month but next with sugarcane bagasse biochar, corn cob biochar, grain chaff biochar etc etc? Or is it possible to develop some general understanding of "irrespective of source, biochar with grain sizes in x range, and y percentage of carbon and z percentage minerals used in proportion w in concrete yields a product with compressive strength ~f(w, x, y, z)"
