摘要

Nanomaterials based on lignocellulosic biomass and agricultural residues are renewable sources that provide a green solution for wastewater treatment, aligning with the goals of the circular economy and decarbonization. These high surface area-based materials possess tunable surface chemistry, are biodegradable, and enable effective pollutant removal. The quantitative data in this meta-analysis is a summation of support in the literature, where the key performance indicators have strong effect sizes (Hedges’ g = 0.78–0.96). The effect size (0.96) of pollutant removal efficiency was the biggest and both treatment scale and the nanomaterial concentration contributed to the effect. Lignocellulosic nanomaterials also facilitate the principle of a circular economy, as they transform agricultural waste into high-value products, facilitate recovery of resources, minimize environmental effects, and make it possible to have low-carbon systems of water treatment. Although their incorporation into wastewater treatment demonstrates working closed-loop approaches, there are bottlenecks in molecular design, scalable green synthesis and functionalization. The future of nanocomposites should be on the development of hybrid nanocomposites, improved surface modifications as well as integration of the materials into industrial symbiosis structures. This article demonstrates the lignocellulosic nanomaterials as a possible motivating force in the regenerative, carbon-focused, and constituent methodologies to environmental cleanup and infrastructure creation.
