Production of high‐purity cellulosic pulps from mango endocarp residue using the green chemical process of peracetic acid

Agro‐industrial wastes are considered a constant management challenge because they are generated in larger quantities than those the landfills are designed for, particularly, the mango pulping industries are facing a series of problems of regulatory compliance, as they generate organic wastes in quantities greater than those regulated in the applicable legislation, the present work has the objective of evaluating the technical feasibility of reincorporating mango endocarp in productive processes to obtain cellulose, using a “green” method that uses peracetic acid as a cooking liquor. The experimentation was carried out at laboratory and pilot scale, the results obtained showed that with the endocarp residues, it is possible to get high‐purity cellulosic fibers with a percentage of lignin lower than 1.35%, quantities higher than 90% of hemicellulose and cellulose, whose thick cell wall structure and poorly developed lumen can be used as a platform for absorbent materials. The yield of the extraction process was higher than 50%. In conclusion, it is possible to take advantage of mango endocarp residue by selective delignification with peracetic acid to obtain high‐quality cellulose.
