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

There has been a growing emphasis placed on the development of environmentally friendly methods for extracting cellulose from natural sources over the course of the past several years. Waste olive wood is a resource that is both abundant and sustainable, and it has the potential to be utilized for the extraction of cellulose through the utilization of a microwave assisted extraction (MAE) technique that is also environmentally friendly. Obtaining cellulose from waste olive wood in a manner that is both environmentally acceptable and effective through the utilization of alkali as a primary component is the purpose of this effort, which aims to develop an MAE process. The extraction process was carried out at 90°C and 100°C for 20 minutes. Where the maximum amount of cellulose obtained yield of 48.64% at 100°C, and the crystallinity index was found to be 62.58%. The microwave with alkali was able to successfully remove the cellulose from waste olive wood, as demonstrated by the scanning electron microscopy (SEM) image, the Fourier transform infrared (FT-IR) analysis, and the thermogravimetric analysis (TGA). In compared to more traditional extraction methods, microwave technology has significantly reduced the amount of time required for extraction as well as the amount of energy that is consumed. As a result, the process has become more environmentally friendly and efficient. The cellulose that has been extracted has the potential to be utilized in a variety of industries, such as the textile industry, the packaging industry, and the biomedical industry. The findings of this study indicate that it is feasible to obtain cellulose of superior quality from olive wood that has been discarded
