Using pollution harvesting and near-zero-waste systems, Mumbai-based Carbon Craft Design is a game-changer for climate change. Founded by architect Tejas Sidnal, the start-up creates stylish tiles by upcycling air pollution. According to them, one carbon tile equals 30,000 litres of air pollution saved. That’s one full day’s worth of clean air per person! With the help of innovative technology, they capture pollution and infuse the carbon in a building material.
