TOKYO -- Japan's JFE Steel has partnered with Tokyo startup Innoqua to recycle steel slag into artificial beds for coral reefs in a venture highlighting a surge of cross-industry collaboration focused on saving the environment.
JFE recently installed a 1-meter tank in the lobby of its headquarters in Tokyo's Hibiya business district. Colorful tropical fish meander in the tank, but they are not meant to entertain visitors and employees.
