As the youngest ever Guardian Sustainable Business leader of the year, 24-year old Arthur Kay started up an innovative green energy company called Bio-Bean in 2013, which collects waste coffee grounds and uses a patented process to recycle them into biodiesel and biomass pellets. Within 2 years, he successfully turns waste coffee into bio-diesel and bio-mass pellets – mainly for powering urban transport and industrial boilers.
Using a patented biochemical process, the 15-20% oil content in waste coffee can be extracted; the remaining 80-85% is then dried, turned into bio-mass pellets and burned as an cleaner alternative to wood chips.
