In Hong Kong's marinas, a new type of vessel is making waves - an uncrewed, solar-powered catamaran, designed to autonomously clean up plastic waste from waterways. It collects floating trash using a conveyor belt, capturing up to 200 kilos per hour. Launched as a university project in 2020, Clearbot has since expanded its operations to various locations across Hong Kong, Thailand, and India, targeting polluted rivers and lakes. The boats are equipped with advanced algorithms for autonomous navigation and waste analysis, providing valuable data to help prevent further pollution. The boats are also able to perform other environmental tasks, such as clearing algae and removing invasive species. The startup aims to revolutionise marine operations by offering an eco-friendly alternative to traditional, fossil fuel-powered boats, thereby contributing to the reduction of marine pollution and promoting sustainable practices.
