In Saga Prefecture, the NPO Karatsu Farm & Food, operating under ‘Precious Plastic Karatsu’, has implemented various plastic upcycling initiatives to promote a circular economy and environmental education. Initially, the Mercure Saga Karatsu Resort collaborated with the NPO to host workshops for hotel guests. Using injection molding machines, participants transformed discarded beverage bottle caps into products such as coasters and recycled plastic bead bracelets. The resort also began selling ‘The Whale’ keychains made from 100% recycled plastic. Following these efforts, the NPO expanded its outreach to educational and public settings. This included a workshop at Tamashima Elementary School where students created keychains from bottle caps, and participation in the ‘Plasm Life Saga’ Plastic Waste Reduction Fair. At the fair, 430 visitors attended, and 150 coasters featuring designs inspired by local mascots and Mawato Island were distributed. ## Timeline ### 2026-10-18: Karatsu Farm & Food hosts plastic upcycling workshops in Saga NPO Karatsu Farm & Food held plastic upcycling workshops in Saga Prefecture, turning bottle caps into keychains and coasters to promote environmental education and a circular economy. 2 sources. https://clstr.news/cluster/karatsu-farm-food-hosts-plastic-upcycling-workshops-in-saga ### 2026-09-27: Mercure Saga Karatsu Resort hosts upcycling workshops Mercure Saga Karatsu Resort and NPO Karatsu Farm & Food are hosting workshops where guests upcycle discarded bottle caps into coasters and bracelets to promote sustainable tourism. 3 sources. https://clstr.news/cluster/mercure-saga-karatsu-resort-hosts-upcycling-workshops --- Cite as: Plastic upcycling initiatives in Saga Prefecture.
