Lignocellulosic residues of banana cultivation: A review of the cellulose extraction chemical processes

Abstract

Banana cultivation is a generator of large amounts of lignocellulosic residues. In Brazil, the fifth largest banana producer in the world, most of these residues are abandoned in plantations, being means of proliferation of vectors and sources of gases harmful to the environment. The cellulose extraction is an important alternative to allocate higher added value to these residues, promoting their reuse. The cellulose extraction process involves the removal of amorphous materials from lignocellulosic materials, especially the lignin. Thus, this study proposed to identify cellulose extraction processes, aiming to assist in the advancement of scientific research and projects that promote the use of cellulose present in these residues. For this purpose, a bibliometric research was conducted in the Science Direct and Springer databases. In the analysis of the material it was identified that the process used for the fragmentation of hemicellulose and lignin is hydrolysis (alkaline, acidic and enzymatic), under controlled conditions.
