Kitakyushu City Water and Sewerage Bureau introduces a pioneering project utilizing slag, a by-product of steel production, to create fertilizer. A demonstration plant in Kokurakita Ward showcases the process, which involves treating slag with hydrochloric acid to extract calcium, then combining it with phosphorus-rich sewage. This method not only recycles waste materials but also produces a phosphate-rich compound suitable for fertilization. The project, a collaboration with Nippon Steel Engineering, represents a unique local initiative, blending industrial heritage with environmental innovation. The bureau aims for further research over the next year to ensure safety and identify suitable crops for this novel fertilizer. Source: Nippon Steel Engineering / NHK
