Ionic-liquid-processed keratin-based biocomposite films with cellulose and chit...
Polesca, C; Passos, H; Nakasu, PYS; Coutinho, JAP; Freire, MG; Hallett, JPPoultry is a widely consumed meat worldwide; however, its industrial processing generates a significant amount of feather waste. Since the major component of chicken feathers is keratin (90 wt%), this study focused on using acetate-based ionic liquids (ILs) to fully dissolve chicken feathers and recover keratin, using a sustainable and cost-effective approach, ultimately allowing waste valorisation. The recover...
Repurposing Kraft black Liquor as Reductant for Enhanced Lithium-Ion Battery Le...
Carreira, ARF; Nogueira, AFM; Rocha, ILD; Sosa, F; Lopes, AMD; Passos, H; Schaeffer, N; Coutinho, JAPThe economic advantages of H2SO4 make it the acid of choice for the hydrometallurgical treatment of waste lithium-ion batteries (LIBs). However, to facilitate the full dissolution of the higher valency metal oxides present in the cathode black mass, a suitable reducing agent is required. Herein, the application of industrial black liquor (BL) obtained from the Kraft pulping for papermaking is investigated as a ...
