“…Dilute acids at range 0.1-10% at high temperatures from100 to 250°C are more economical and environmentally friendly but require longer processing times. One major challenge of acid pretreatment is the formation of inhibitory compounds like furfurals and phenolic acids, which hinder subsequent enzymatic hydrolysis and fermentation [42]. Chemical and biological detoxification methods are employed to mitigate this issue.…”

Despite concerns about diminishing fossil fuels and the imperative for renewable alternatives, lignin, Earth’s most abundant aromatic biopolymer, remains largely underutilized. This chapter explores the immense potential of lignin biorefinery to address energy demands, promote economic growth, and adhere to sustainable development principles. However, intricate structure, harsh odor, and toxicity hinder its valorization. To address these issues, examining emerging biochemical strategies, including thermochemical and enzymatic depolymerization and physical techniques, have emerged as promising avenues for converting lignin into valuable biofuels and chemical compounds. By highlighting innovative approaches and technologies, it emphasizes the pivotal role of lignin in driving biorefineries toward low-emission processes, yielding a diverse spectrum of bio-products. This chapter aims to contribute to the ongoing discourse on sustainable and eco-friendly biorefinery practices of lignin valorization.

“…Since different types of systems can be separated, researchers have studied various kinds of strategies over the years, and the separation process is not a type of process that applies to all kinds of systems; therefore, all of these strategies are efficient in different ways for different kinds of systems [8]. These methods use innovative techniques to provide a more effective way of recovering desired materials without the constraints that are encountered using conventional ways [9].…”

This study modelled and optimised an autoclave-assisted acid pre-treatment of waste sugarcane molasses for the recovery of reducing sugar. Afterwards, the efficiency of removing 5-hydroxymethylfurfural (5-HMF), furfural, and metallic ion inhibitors from the pre-treated hydrolysate was evaluated using a nano-based adsorbent towards bioproduct production. A high coefficient of determination (R2 = 0.98) and a maximum reducing sugar concentration of 98.14 g/L were achieved under optimised conditions of 20% (w/v) substrate loading, 0.75% (v/v) sulphuric acid concentration, and 5 min autoclave duration. Furthermore, the application of nano-adsorbent (Fe3O4 nanoparticle (0.2% (w/v)) led to a reduction in 5-HMF and furfural concentrations by 29.05% and 53.53%, respectively. Additionally, the concentrations of metal ion contents (Ca, Mg, Na, and S) were reduced by 4.97%, 7.59%, 15.04%, and 7.63%, respectively. Remarkably, surface modification of Fe3O4 nanoparticle using poly (ethylene glycol) (PEG), tri sodium citrate (TSC), chitosan-coated and k-carrageenan (k-C) enhanced the removal of metal ion contents up to 42.74-fold. The potential of the optimised pre-treated and detoxified molasses for citric acid (4.04 g/L) and bioethanol production (47.93 g/L) was achieved. The high efficiencies in reducing sugar recovery, inhibitor removal, and bioproduct production demonstrate the potential of a sustainable, cost-effective, and eco-friendly molasses biorefinery concept.
