Superabsorbent food packaging bioactive cellulose-based aerogels from Arundo donax waste biomass

A. donax waste biomass has been valorized for the extraction of cellulosic fractions with different purification degrees, as well as aqueous bioactive extracts, which were then combined to develop superabsorbent bioactive aerogels. All the developed aerogels presented excellent water and oil sorptio...
