The urgent need to replace fossil-based resources with sustainable alternatives calls for innovative strategies in biomass valorization. Among these, the efficient use of lignocellulosic biomass has proven particularly promising. Although a complete substitution of fossil fuels is unlikely, biomass can serve as a viable and renewable feedstock for a significant fraction of chemical production....
This study explores the upcycling of grinding swarf, a by-product of subtractive machining, into semi-finished cast products by recovering silicon carbide (SiC) and aluminum oxide (Al₂O₃) abrasives and using them as alloying additions. Two cold-work tool steels, X153CrMoV12 (1.2379) and 80CrV2 (1.2235), were modified, with emphasis on X153CrMoV12 due to its higher content of critical alloying...
Hypervalent iodine reagents offer powerful oxidative capabilities and have emerged as attractive, metal-free alternatives to traditional oxidation methods that often rely on toxic metals. However, their high-energy character can raise significant safety concerns, especially in traditional batch processes. In response to these challenges, we have developed a series of continuous flow...
Multi-criteria decision-making for product selection in construction is becoming increasingly important, as purely technical and economic evaluations can no longer capture the complex demands of sustainability. In particular, ecological and socio-cultural criteria exert a decisive influence on the life-cycle assessment (LCA) of building materials and are embedded in certification systems such...
