Green Extraction of Cellulose from Waste Olive Wood Using Microwave Assisted Alkali Treatment

There has been a growing emphasis placed on the developmentof environmentally friendly methods for extracting cellulose fromnatural sources over the course of the past several years. Wasteolive wood is a resource that is both abundant and sustainable, andit has the potential to be utilized for the extraction of cellulose throughthe utilization of a microwave assisted extraction (MAE) techniquethat is also environmentally friendly. Obtaining cellulose from wasteolive wood in a manner that is both environmentally acceptable andeffective through the utilization of alkali as a primary component isthe purpose of this effort, which aims to develop an MAE process.The extraction process was carried out at 90°C and 100°C for 20minutes. Where the maximum amount of cellulose obtained yieldof 48.64% at 100°C, and the crystallinity index was found to be62.58%. The microwave with alkali was able to successfully removethe cellulose from waste olive wood, as demonstrated by thescanning electron microscopy (SEM) image, the Fourier transforminfrared (FT-IR) analysis, and the thermogravimetric analysis (TGA).In compared to more traditional extraction methods, microwavetechnology has significantly reduced the amount of time requiredfor extraction as well as the amount of energy that is consumed. Asa result, the process has become more environmentally friendly andefficient. The cellulose that has been extracted has the potential tobe utilized in a variety of industries, such as the textile industry, thepackaging industry, and the biomedical industry. The findings of thisstudy indicate that it is feasible to obtain cellulose of superior qualityfrom olive wood that has been discarded.
