Polylactic Acid (PLA), Polycaprolactone (PCL), and Chitosan: the Biodegradable Transition in Medical Waste Management

open access: yesAdvanced Sustainable Systems, EarlyView.
The shift to biodegradable materials in healthcare promises reduced plastic pollution, but their production, adoption, and long‐term impacts remain complex. Integrating lifecycle insights with global policy coordination is essential for meaningful environmental gains. Abstract The COVID‐19 pandemic sharply increased medical waste, intensifying concerns

Techno‐Economic Analysis of Polylactic Acid from Corn Stover: Understanding Uncertainty and Variability via Artificial Intelligence Tools

open access: yesAdvanced Sustainable Systems, EarlyView.
This study analyses the uncertainty and variability existing in the economic performance of polylactic acid (PLA) production, via integrating techno‐economic analysis with process models and Monte Carlo simulation enabled by artificial intelligence. The results show that the minimum selling price varies from $2,107 to $3076/t PLA.

Bioenergy Potential of Europe's Perennial and Biennial Wildflowers: A Combustion Performance Benchmark

open access: yesAdvanced Sustainable Systems, EarlyView.
Eight wild plant species were investigated as co‐substrates for pellet combustion. A long‐term field trial examined dry matter yield and biochemical composition, influencing combustion properties. Results show suitable combustion properties, comparable to Sida, with higher ash melting temperatures than Miscanthus, due to elevated calcium and magnesium.

Elderly Liver Grafts are More Susceptible to Ischemia‐Reperfusion After Prolonged Cold Ischemia than Grafts from Young Donors—An Ex Vivo Liver Machine Perfusion Analysis in Sprague Dawley Rats

open access: yesAdvanced Therapeutics, EarlyView.
This study investigates how donor age and cold ischemia time influence liver perfusion parameters and injury markers. Older livers are more susceptible to longer ischemia times displaying more tissue damage, and higher expression of oxidative stress and apoptosis‐related proteins than livers with shorter ischemia times.
