Evaluación de la metodología Kurschner y Hoffner en la producción de papel kraft a partir de la cascarilla de cacao (Theobroma cacao) utilizando aditivos derivados del pseudotallo de plátano (Musa paradisiaca) y jacarandá (Jacaranda copaia).

Abstract

The demand for unsustainable paper production has become a threat to natural resources. Besides, agricultural residues are not used. The outcome of this research was to evaluate the Kurschner and Hoffner methodology in the production of Kraft paper from cocoa husk (Theobroma cacao), using additives derived from banana pseudostem (Musa paradisiaca) and jacaranda wood (Jacaranda copaia). For this reason, lignin and cellulose husk content in several cocoa varieties were analyzed. Second, for each type of additive, an AxB experimental design was used to produce Kraft paper, where the factors were the cocoa variety (CCN51, Nacional, Super Árbol) and the additive dose (0, 25, 50, 75) percent. Third, the thickness and tensile strength of the Kraft papers produced with the standards for industrial use were analyzed. The final results showed that, in the raw material, the lignin and cellulose content of all cocoa varieties was statistically equal. As for the additives, jacaranda wood had a higher lignin and cellulose content than banana pseudostem. On the other hand, for papers made with banana pseudostem as an additive, it was observed that all papers complied with the thickness values established in the standards, but did not comply with the tensile strength limits for industrial use. Finally, for papers made with jacaranda wood as an additive, only the Super Árbol-0 percent, Nacional-0 percent, and CCN51-0 percent treatments complied with the thickness values established in the standards; however, it was observed that no paper complied with the tensile strength values for industrial use.
