Utilization of Waste Materials Using the Müller–Kühne Process—A Life Cycle Inventory Study
Chemie Ingenieur Technik, EarlyView.This study presents a Life Cycle Inventory of the Müller–Kühne process (MKP), which converts gypsum waste into sulfuric acid and cement clinker. The MKP outperforms conventional cement production regarding material yield, though its specific energy demand is higher. Consequently, potentials for circular gypsum waste utilization are discussed.
