Renewable raw materials and sustainability has a widespread significance for all types of industry. Cellulose, which has a great potential as a raw material for various branch of industry including textile, is the main component of most vegetable fibers. Cellulose from different vegetable resources can be isolated using chemical and mechanical treatments. Chemical treatments are effective for delignification. Based on this, the aim of our study is extraction of sustainable cellulose from ligno-cellulosic banana plant waste using chemical treatment. First, the waste banana plants were supplied as resource of cellulose considering the previous works about this topic and preliminary experimental studies. After that, the composition of the extract was determined in order to confirm the high cellulose content. At the next stage of this study, organic acid extraction method was used to extract cellulose from banana plant wastes. The cellulose content of banana plant was determined as 57% and 24% of hemicellulose. The cellulose was successfully extracted from banana plant wastes. Characterization results suggest that cellulose, an important raw material for textile, pulp and paper, composite and defense industries, can be effectively regained from banana plant wastes.
