Other than kickstarting someone's morning with a dose of caffeine at 7:00 a.m., what else can a strong cup of tea do? Macao designer Calvin Sio isn't just passionate about tea – he draws inspiration from it. By transforming waste materials like tea dregs and herbal residues, he has created eco-friendly products such as tea cups and tea tables. His innovative work has earned him a spot on Time magazine's annual list of the 100 best inventions. With the increasing integration of the Guangdong-Hong Kong-Macao Greater Bay Area, Calvin sees his products reaching an even wider market.
