Germany: Scientists at the University of Kassel in Hessen have launched a study into the use of ash from waste incinerators in precast concrete production. The Hessische Allgemeine newspaper has reported that a waste-to-energy plant in Kassel will provide the ash for concrete production in partnership with local companies Kimm Baustoffe and Gebäudeke Baustoff-Recycling. The study aims to produce pre-cast concrete elements containing at least 30% ash, beginning with paving slabs and noise barriers.

Project leader David Laner said that ash has the potential to help lower concrete’s carbon footprint. He said “So far, it has been put to lesser-value uses; we make a product out of it - upcycling instead of downcycling.”
