Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

Bioeconomy, sustainability, and digital technologies in Haematococcus lacustris biomass and astaxanthin production: advances and outlook

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris, its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attractive for pharmaceutical and ...

Design of azine antioxidants for sustainable biodiesel: integrating structural characterization and molecular modeling

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The growing global demand for sustainable energy solutions has intensified the search for renewable alternatives to fossil fuels, with biodiesel emerging as a promising candidate due to its biodegradability and lower emissions. However, its large‐scale application is limited by low oxidative stability, which compromises storage and performance.
