This paper describes the use of agricultural wastes for the preparation of carboxymethylcellulose (CMC) with ahigh degree of substitution using two methods: the classic and a microwave-assisted method. A series of CMC samples withdegrees of substitution from 0.43 to 2.83 were prepared from cellulose extracted from almond shells, almond stems, and figstems by a one-step carboxymethylation reaction. The highest degree of substitution was 2.83, which corresponded to CMCfrom fig stems when butanol was used as a solvent. This CMC was easily dissolved in water and thus would provide manyopportunities for diverse applications. The obtained CMCs were characterized using different tools. Different CMC filmswere prepared using the casting method and were characterized by the determination of their mechanical properties. Theobtained results can be considered promising; they demonstrate the potential of using cellulose derivatives for the productionof transparent and strong films.
