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.

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...
