Tadas Lisauskas is the founder and CEO of San Diego-based Greenbutts. The company has invented a revolutionary cigarette filter material that may well have a shot at eventually displacing the presently used (but environmentally unfriendly) cellulose acetate tow (CAT). The Greenbutts substrate is 100% plastic-free, as it is composed solely of natural fibers and a starch-based binding agent. When immersed in water, Greenbutts completely disintegrates and disperses in 30 days, while on land it takes about 60 days. There are no residues left behind, let alone dreaded micro plastics. Lisauskas talks to Thomas Schmid about the numerous advantages of the patented material, but also discloses why the industry is so reluctant in adopting it on a broader scale.
