Vincent talks to Liam Lysaght and Harry Jankola, two of the co-founders of FiltraCycle , a sustainability startup based in Dublin, Ireland, that recycles cigarette butts, a major source of environmental pollution.

Their mission is "to intercept millions of tonnes of pollution from damaging our environment, and to protect our oceans". Their recycled plastic - FiltraPlastic - Is "A Raw, Sustainable Alternative To Traditional Acetate Plastic".

Still in their final year of University at Trinity College, Liam and Harry provide an example of young entrepreneurial spirit driven by the pressing need to find innovative solutions to the sustainability challenges we face.
