Pyongyang, January 31 (KCNA) -- The State Academy of Sciences and the Academy of Railway Science in the DPRK have developed new recycling technologies of high economic value. The State Academy of Sciences established a technological process for producing aluminium hydroxide with aluminium solution waste material. Thus, a sci-tech guarantee was provided to produce aluminium hydroxide independently while making much profit. The Academy of Railway Science developed a technology for producing phosphorus barking shoe with ferro-phosphorus. The development of phosphorus barking shoe, which has a twice longer life than cast iron barking shoe, makes it possible to save a large amount of pig iron and ferro-silicon.
