Insights into Lignocellulosic Fiber Feedstock and its Impact on Pulp and Paper Manufacturing: A Comprehensive Review

Abstract

Concerns about the depletion of wood resources and the environmental impact of increasing demand for paper goods have led to the quest for alternate sources of fiber for pulp and paper manufacture. Non-wood fibers, such as agricultural residues, are seen as a sustainable and renewable source of fiber. However, due to changes in chemical composition, unpredictability, and processing methods, their utilization offers obstacles. Nonetheless, ongoing research in non-wood fiber pulping drives the development of new methods and technologies to enhance non-wood fibers' processability. Kraft pulping, known for efficacy and adaptability, is prominent among major industry players. This study aims to assess the feasibility of harnessing lignocellulosic non-wood fibers as wood alternatives for pulp and paper manufacturing, while also investigating the impacts of pulping processes on these fibers. Notably, innovative pulping methodologies have emerged to address shortcomings inherent in conventional approaches. Furthermore, exploration of alternative compounds as replacements for conventional chemicals aims to mitigate their ecological footprint. Despite the existing constraints, non-wood fibres demonstrate significant promise as environmentally friendly and renewable resources within the pulp and paper industry. Based on the analysis conducted, it can be inferred that the growing interest in non-wood alternatives would likely drive breakthroughs in pulping technologies and material science. These advancements are expected to result in more efficient approaches for harnessing the potential of non-wood fibres. This study makes a valuable contribution to the overarching goal of promoting environmentally sustainable and economically efficient methods for the manufacture of pulp and paper.
