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

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1656-1676, April 2026.
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 ...

Climatic Stress Versus Anthropogenic Degradation: An Ecohydrological Perspective on the Drivers of Net Primary Productivity in a Seasonally Dry Tropical Forest

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Water‐limited ecosystems play a fundamental role in the global carbon cycle, yet they have been increasingly affected by pressures from aridification and land‐use and land‐cover change. The Caatinga, the largest seasonally dry tropical forest in South America, exhibits strong ecohydrological coupling resulting from centuries of adaptation, in ...

Bio‐Inspired Cascade Photocatalysis on Fe Single‐Atom Carbon Nitride Upcycles Plastic Wastes for Effective Acetic Acid Production

open access: yesAdvanced Energy Materials, Volume 16, Issue 9, 4 March 2026.
This work demonstrates a novel cascade photocatalysis concept using Fe single‐atom catalysts (Fe@C3N4 SAC) to directly upcycle plastics (PET, PP, PE, PVC) into valuable acetic acid at ambient conditions. Inspired by microbial degradation, the bifunctional cascade photocatalyst combines Fenton‐like oxidation and CO2 photoreduction, as validated by ...
