By mixing the 100 percent recycled cement with recycled water, recycled rebar and other recycled components, 100 percent recycled concrete is scheduled for delivery in the 3Q22. According to Edelio Bermejo, Head of Holcim's Innovation Centre, this breakthrough shows what is possible when you combine Holcim's unique expertise in recycling with its leadership in cement production. Developing 100 percent recycled clinker is taking us one step further in our quest to drive circular construction to decarbonise the built environment." Producing clinker from 100 percent recycled material involved a combination of sourcing the right waste streams and designing the best physical layout to re-engineer clinker production. The breakthrough trial in Altkirch used alternative raw materials, ranging from wood ash to waste from mineral processing, largely from local sources.
