Lignocellulosic biomass which is mainly composed of cellulose, hemicellulose, and lignin, is an abundant and renewable resource of biomass with great potential for producing valuable biomaterials. However, its complex structure and the inefficiencies of traditional processing methods present challenges in its sustainable conversion. Recent advances in nanotechnology have introduced new avenues to transform lignocellulosic biomass into useful products such as nanomaterials, biofuels, nanocellulose, biochar, and nanofertilizers. For instance, nanocellulose derived from lignocellulosic feedstocks exhibits tensile strength exceeding that of steel at comparable densities, while biochar production has shown to sequester up to 50% of the initial carbon content of biomass, enhancing soil fertility. These innovations improve biomass processing efficiency and offer more sustainable alternatives. This review explores the latest techniques for converting lignocellulosic biomass into novel biomaterials, their applications in various sectors such as agriculture, energy, and environmental management. Quantitative analysis from the reviewed literature reveals that incorporating metal oxide nanoparticles, such as Fe3O4, can enhance enzymatic hydrolysis rates by up to 40%, and biofuel yields can be increased by approximately 30% when nanotechnological interventions are applied during fermentation processes. Moreover, different challenges involved in scaling these technologies for industrial use have also been discussed. Sustainable utilization of lignocellulosic biomass can contribute to the development of a circular economy, reducing waste and dependence on fossil fuels while supporting global sustainability efforts.
