One pot green process for facile fractionation of sorghum biomass to lignin, cellulose and hemicellulose nanoparticles using deep eutectic solvent.

Complete valorization of lignocellulosic biomass is crucial for bio-based biorefineries to fulfil the circular bioeconomy concept. However, the existence of lignin carbohydrate complexes (LCC) in biomass hinders the simultaneous fractionation of biomass components, such as lignin, hemicellulose and cellulose, for subsequent biorefining processes. This study explores for the first time a novel approach tailored for the deconstruction of sorghum biomass components through efficient breakdown of LCC.

Biomass-derived nanoparticles reinforced chitosan films: as high barrier active packaging for extending the shelf life of highly perishable food.

Unlabelled: This study emphasizes the potential of biomass-derived nanoparticles such as nanocellulose (NC), nanohemicellulose (NHC), and nanolignin (NL) as reinforcements in chitosan (C) films to produce a higher barrier active packaging film. The incorporation of NC, NHC, and NL (1.5%) significantly improves the mechanical, water, and UV barrier properties of the chitosan film ( < 0.

Cleaner approach for the cascade production of nanocellulose, nanohemicellulose and nanolignin from Prosopis juliflora.

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.

A neoteric approach for the complete valorization of Typha angustifolia leaf biomass: A drive towards environmental sustainability.

Exploring new biomass resources and developing a sustainable process for holistic utilization has become crucial due to the high demand for bio-based chemicals as alternatives to petrochemicals. Herein, we describe a novel approach to valorize the Typha angustifolia leaves, underutilized biomass into cellulose, hemicellulose and lignin nanoparticles. The process was framed in a sequence to isolate hemicellulose in the first step due to its highly reactive nature and then separate cellulose and lignin.

Energy efficient process for valorization of corn cob as a source for nanocrystalline cellulose and hemicellulose production.

Synthesis of nanoparticle from biopolymers present in agricultural waste residue is significant as they are eco-friendly and serve as alternative to unrenewable petroleum resources. This research focuses on utilizing Corn cob, a lignocellulosic biomass for the simultaneous production of cellulose and hemicellulose using an energy efficient method. A sequential process of microwave irradiation and ultrasound technique is carried out to obtain cellulose and hemicellulose at a faster rate.

Optimization of electrocoagulation process to treat grey wastewater in batch mode using response surface methodology.

Background: Discharge of grey wastewater into the ecological system causes the negative impact effect on receiving water bodies.

Methods: In this present study, electrocoagulation process (EC) was investigated to treat grey wastewater under different operating conditions such as initial pH (4-8), current density (10-30 mA/cm2), electrode distance (4-6 cm) and electrolysis time (5-25 min) by using stainless steel (SS) anode in batch mode. Four factors with five levels Box-Behnken response surface design (BBD) was employed to optimize and investigate the effect of process variables on the responses such as total solids (TS), chemical oxygen demand (COD) and fecal coliform (FC) removal.

Model development and process optimization for solvent extraction of polyphenols from red grapes using Box-Behnken design.

The objective of the present study is to find out the optimum extraction conditions for extraction of polyphenols from red grapes using Box-Behnken design. Red grapes polyphenols were extracted using acid-ethanol solvent at various extraction temperature (40-60°C), extraction time (20-100 min) and different solid-liquid ratio (1:5-1:15 g:ml). The effect (main and interactive) of extraction conditions on total anthocyanin, phenolic and flavonoid content were studied using Box-Behnken design (three factors at three levels).
