Characterization of the Compounds Released in the Gaseous Waste Stream during the Slow Pyrolysis of Hemp (Cannabis sativa L.)
(MDPI, 2022-04-27)This study aims to characterize and valorize hemp residual biomass by a slow pyrolysis process. The volatile by-products of hemp carbonization were characterized by several methods (TGA, UV-VIS, TLC, Flash Prep-LC, UHPLC, ... -
Characterization of Wood‑based Industrial Biorefinery Lignosulfonates and Supercritical Water Hydrolysis Lignin
(Springer, 2020-11)Understanding the properties of any particular biorefinery or pulping residue lignin is crucial when choosing the right lignin for the right end use. In this paper, three different residual lignin types [supercritical water ... -
Chicken feathers as a natural source of sulphur to develop sustainable protein films with enhanced properties
(Elsevier, 2017-08-05)In this work, the effect of hydrolyzed keratin on the properties of soy protein-based films was analyzed when different manufacture processes were employed. It is widely known that the processing method selected can affect ... -
Chitin nanowhisker-containing photo-crosslinked antimicrobial gelatin films
(Elsevier, 2024-02)Nearly 57 Mt of food waste are generated annually in the EU for many reasons, for instance, because of microbial food spoilage. So, actions to reduce food loss and waste are needed and active packaging could offer a new ... -
