Spirit of Hong Kong Awards: Company uses 3D-printed tiles to restore coral reefs

The Spirit of Hong Kong Awards commend a company that uses 3D-printed tiles to restore coral reefs. In 2014, a University of Hong Kong research team's two-year restoration work in Sai Kung ended in failure: the Agriculture, Fisheries and Conservation Department called for faster coral recovery, and corals growing on cement structures became unstable because they "had no roots".
