Facile and green lyocell/feather nonwovens with in-situ growth of ZIF-8 as adsorbent for physicochemical CO2 capture

•ZIF-8@LFNW adsorbent is prepared by a green and facile approach.•ZIF-8@LFNW achieves both physical and chemical interactions with CO2.•Considerable CO2 capture capacity of 4.46 cm3 g−1 from high CO2 concentration and 190.84 ppm g−1 from low CO2 concentration were proved.•Waste feather is masterfully transformed into value-added CO2 capture material.
