RODRIGUEZ-MARTINEZ, Guadalupe et al. Utilization of Cellulose Derived from Agro-Industrial Waste for Biopolymer Formulation: A Systematic Review. Enfoque UTE [online]. 2026, vol.17, n.2, pp.33-43. ISSN 1390-6542.  https://doi.org/10.29019/enfoqueute.1240.

The objective of this systematic review is to analyze the main scientific advances related to the use of cellulose extracted from agro-industrial residues for the formulation of biopolymers. To this end, a systematic review of the scientific literature published between 2015 and 2024 was conducted using the Dimensions database, considering studies associated with agro-industrial residues, biomaterials, and biopolymer production methods. The selected studies were evaluated through bibliometric analysis and keyword co-occurrence tools, which enabled the identification of research trends, scientific output, and predominant technological approaches.

The results indicate that agro-industrial residues constitute an abundant and sustainable source of cellulose, whose valorization promotes the circular economy and reduces environmental impact. Various cellulose extraction methods were identified, including alkaline treatment, acid treatment, bleaching, enzymatic processes, and methods based on green solvents. The latter represents one of the most recent trends and, compared to other methods, yields cellulose with a high degree of purity; however, its main drawback is the high production cost. In this context, acid hydrolysis remains one of the most widely used methods despite involving corrosive reagents.

Cellulose extracted from agro-industrial residues is used as a raw material in the production of biopolymers. For the fabrication of biopolymer films, molding is the most commonly employed technique. The main applications of biopolymers derived from agro-industrial residues were identified in the food industry, particularly in food packaging and containers. Overall, the literature demonstrates the growing scientific interest and technological potential of these materials as sustainable alternatives to conventional polymers.
