Clinker based on calcium looped meals from the Cleanker Project.

The Cleanker (CLEAN clinKER production by Calcium Looping process) project, financed in the framework of Horizon 2020 EU funding program, has demonstrated the feasibility of the integrated CaL concept at industrial scale in a new demo system realised in the Buzzi Unicem cement plant in Vernasca (IT). The Calcium Looping (CaL) CO capture process exploits the reversible reaction of limestone calcination/carbonation (CaCO ↔ CaO + CO). The Cleanker pilot plant consists of the coupling of a carbonator and an oxyfuel calciner.
