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

Abstract Anaerobic digestion can be an alternative method for treating wastewater from second‐generation biorefineries while simultaneously producing biogas. However, the feasibility of the process and key operational parameters by which wastewater produced in lignocellulosic biorefineries affects reactor performance remain poorly understood.

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 ...

Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...
