New sustainable plant-based membrane works without fossil-fuel materials and toxic solvents  - Water Magazine

Chemical engineers at the University of Bath have made an effective and more sustainable plant-based nanofiltration membrane, which – in a world first – does not use fossil fuel-derived materials or toxic solvents. Made from two renewable and sustainable plant-derived materials – cellulose and lignin – the new polyelectrolyte membrane (PEM) design has been proven in testing to effectively filter water dyes of a range of different molecular weigh…
