Biodegradation and ecotoxicological impact of cellulose nanocomposites under Controlled Composting Conditions

The biodegradability of cellulose nananofiber-PVA nanocomposites were studied under controlled composting conditions and the quality of the compost was evaluated. The nanocomposite based on PVA with 5, 10, 20 and 30 wt % of CNF was prepared by using liquid nitrogen and freeze drying techniques. Spec...
