Materials based on fossil fuels have a strong environmental impact, so it is necessary to develop renewable materials. Nanocellulose is an emerging renewable nanomaterial that has promising applications in different domains, such as in foods, pharmaceuticals, personal care, electronic, and for green nanotechnology. Plants are the most abundant source of cellulose, which through chemical treatments of various types can lead to the production of nanocellulose. In this work we obtained cellulose and nanocellulose from Schoneoplectus californicus, a very abundant plant considered as a plague in dams, lakes and lagoons. Cellulose was extracted by carrying out alkali and bleaching treatments and nanocellulose was isolated by an acid hydrolysis. The cellulose was characterized by Fourier Transform Infrared Spectrophotometry (FTIR), this analysis confirmed the elimination of non-cellulosic components due to the absence of the band in the region of 1730 cm-1 which is attributed to the stretching vibration of C=O of the ester groups in hemicellulose and lignin. Structural analyses was performed by X-ray diffraction (XRD) where the diffractogram exhibits representative peaks of the characteristic structure. Scanning Electron Microscopy (SEM) analysis determined that the isolated nanocellulose from S.californicus was found to be with a width of approximately 150 nm.
