Membrane technology in the field of biogas purification is preferred over other conventional
processes as it offers easy installation, cheaper processing cost, and reduced carbon
footprint. Membrane technology has been majorly exploited in biogas separation in the
recent past. As a promising CO 2 separation approach from biogas based on facilitated
transport mechanism, nanocellulose-based membranes add great advantages like high
specific surface area, hydrophilicity, surface modification possibility, environmental …
