France: Holcim France has announced its successful industrial-scale production of the world's first 100% recycled clinker. The La Tribune newspaper has reported that the company's Altkirch, Alsace, cement plant produced the clinker. Holcim France chief executive officer Francois Petry said that the plant's team collaborated with researchers at the Holcim Innovation Center to develop a recipe that incorporated multiple waste streams, including mineral wastes and wood ash. The producer says that most of the waste materials were locally sourced.
