![]() Tomimoto's organisation has even ventured into beauty treatments - selling seaweed to bathhouses to put in their tubs, and to cosmetics company Lush to make bath bombs. The brown strands of kelp take just four months to grow long and thick, and are then pulled up and cut from ropes submerged in the harbour © Philip FONG / AFPĪ 2021 study by the University of California, Davis found that replacing a small part of a cow's diet with a type of red seaweed reduced methane emissions by over 80 percent. They are washed and dried, with some chopped up to be sent to businesses, including green tea plantation Matoba-en, which uses it as organic fertiliser. The brown strands of kelp take just four months to grow long and thick, and are then pulled up and cut from ropes submerged in the harbour. That is now changing, and Sachiumi Heroes is one of several new initiatives in Japan, from fisheries selling "blue carbon" credits to efforts to restore wild seaweed forests. "The Japanese have a history of eating seaweed, but we haven't ever really thought of farming it from an environmental or ecological point of view," he told AFP. Most of the kelp harvested by Kigawa and his colleagues at their port in Yokohama is sold to be boiled in soup stock and added to healthy salads.īut some will go to projects run by the organisation Sachiumi Heroes "to preserve the ecosystem and tackle global warming", said the group's founder, Tatsunori Tomimoto. Research into new applications for the marine plant - from carbon absorption to reducing methane emissions from cattle - is flourishing, and countries are looking to Asia's seaweed savvy to develop their own industries.
