“…One of the products produced recently from cellulose are cellulose aerogels. Cellulose aerogels are a viable cellulose-based alternative product with promising potential for diverse applications. − These aerogels are among the lightest materials known, exhibiting an extremely porous structure due to the air volume that they contain, about 90–99% . Researchers have expressed significant interest in aerogels with advanced properties and a three-dimensional cross-linked network structure, primarily due to their high surface area, low density, and exceptional thermal insulation capabilities .…”

Cellulose was extracted from waste generated by pruning tea stem wastes. The interaction between pure cellulose and homophthalic acid produced a light (0.22 g·cm–3) and eco-friendly hybrid aerogel product that is highly absorbent (85 g of water per 1 g of aerogel). The product has a Brunauer–Emmett–Teller surface area of 221 m2·g–1. In addition, the product was analyzed for its structural and functional properties using scanning electron microscopy, Fourier transform infrared, and X-ray diffraction. The methodology employed in this study is uncomplicated, utilizing easily accessible and sustainable biowaste at a low cost. As a result, the current process is well-adapted for industrial-scale production, with the potential for significant advancements in the field of green materials.
