Biodegradable cigarette filters achieve key patent

In San Diego, biodegradable filter manufacturer Greenbutts says it has been granted a patent for ‘Biodegradable Cigarette Filter Tow and Method of Manufacture,’ which covers its food-grade, fiber-based filters with starch-based binders. 

Greenbutts’ filter material is a sustainable alternative to the standard filters made of synthesized cellulose acetate and has been shown to degrade in compost within a matter of days and disperse in water within minutes. 

“Greenbutts’ mission started 12 years ago, at a time when the phrase ‘single-use plastic’ was not used as often as it is today. Our dedication through extensive R&D with our world-class scientific team is now being recognized on a global scale as governments, industry and consumers are all in alignment with a green, clean future,” says Tadas Lisauskas, CEO.

Canadian Patent No. 2,949,484 is of “strategic importance” because of the Canadian government’s decision to ban the manufacture and importation of harmful single-use plastics, Lisauskas adds. “Our technology is a viable and sustainable alternative to cellulose acetate filters while maintaining the sensory experience, delivering the high-performance filtration capability of a traditional filter. As we continue progressing with our commercialization roadmap, growing our intellectual property portfolio will be an essential factor towards the maturity of the Company, especially with government and industry recognizing Greenbutts as a green alternative to plastic filters.”
