Structure and Source of Cellulose. Cellulose, a fascinating and sustainable feedstock, is the most abundant polymeric raw material on earth. Its annual production is estimated to be between 10 10 and 10 11 t, but only a small portion of 6 × 10 9 t is exploited by a number of industrial fields such as papers, textile, chemical, and material industries (Trache et al., 2020).
