This research focuses on developing a cleaner approach for the cascade production of nanocellulose, nanohemicellulose and nanolignin from Prosopis juliflora biomass. Via screening experiments, LA2/ChCl NADES was selected for selective hemicellulose solubilization in the first stage, and FA3/ChCl was selected for lignin solubilization in the second stage. This two-stage cascade process integrated with microwave gives a higher recovery yield (96.8 % cellulose, 92.43 % hemicellulose and 90.56 % lignin). Subsequently, recovered particles were converted into nanoparticles using intense ultrasonication. The produced nanocellulose, nanohemicellulose and nanolignin typically had a spherical structure with an average particle size of 87.4 ± 5.1 nm, 68.8 ± 2.1 nm, and 77.8 ± 2.6 nm. Nanoparticles produced by this study have many potential applications, especially in food, biomedical and packaging sectors. In addition, 80 % of LA2/ChCl NADES and 98 % of ethanol were recovered and reused. This approach of the holistic utilization of an invasive species rather than eliminating it paves a path towards environmental sustainability. Copyright © 2022 Elsevier Ltd. All rights reserved.
