Power display Nippon Steel reproduces soil "of the mountain which is full of" for "algae ground" reproduction

トリーバーチAlgae ground of Mashikecho, Hokkaido that regenerated soil "in delivery macrophotograph Beverly at 18:15 on reproduction Sankei Shimbun Saturday, August 18 of the mountain where power display Nippon Steel is full of" for "algae ground" reproduction (a photograph:) A technique of Nippon Steel shows power by reproduction of "the algae ground" that seaweed grows thick in Sankei Shimbun) coastal place. A bag and a box can checkmate the product which devised an additive to a base and only spend slag occurring as a by-product of the iron manufacture underwater and are structure supplying humus acid iron which is indispensable to growth of seaweed. I receive the certification as safe 漁場造成用資器材, and the use seems to advance in future in each place. Seaweed or the kombu which covered the sea average disappear suddenly, and a phenomenon called "the seawater damage" that the bottom of the sea such as the wasteland spreads through is confirmed in the sea of each place of the whole country. It affects not only the seaweed but also a turban shell and an abalone, the fishery of the fish, and the reproduction of the algae ground becomes the urgent business. It is a Katsuhiko Matsunaga former honorary professor of Hokkaido University to have theorized mechanism of the seawater damage. Humus formed in neighboring mountains by a large quantity of dead leaves holds the key. A material called フルボ acid made in humus is combined with iron of mountains and makes 2 values iron which seaweed is easy to use and flows into the sea. The deep mountains where broadleaf trees grew thick created the rich seas, but what this structure felled the forest, and was cut off concluded it to be a cause of the seawater damage. Based on this theory, the Naoto Tsutsumi and others of the technology development Planning Department warming measures study plan group of Nippon Steel utilized slag to produce in a steel manufacture process and started technology development to supply 2 values iron in seawater. Iron purity of the iron ore which the company uses is approximately 60%, and a large quantity of slag is produced through the pig iron in the blast furnace, the steel manufacture process using the converter. The slag included iron content 10 several percent and has been used as high-strength roadbed materials and cement materials. If a prevention of seawater damage effecIt is a big pile in the workshop of the "pollution car scrap" housebreaker which lost a place to got is provided, I can reclaim a new use of the slag. In addition, "the algae ground is important to the global warming measures top from the viewpoint of ability for absorption of carbon dioxide, and the social contribution degree is high, too" (the company). However, the elution effect of the iron content is restrictive even if I just put slag in seawater. Therefore I mixed the humus which I made from wood chips artificially with particle-shaped slag and reproduced soil "of the mountain which was full of". I filled the bag made of palm patterns with this material, and, in October, 2004, a proof experiment to install in the shore of Mashikecho, Hokkaido where seawater damage was serious was performed in Nippon Steel and Tokyo University. A half year later, wonderful kombu grew thick around a setting place. Control experiment with slag and the humus was performed with a water tank of the abalone middle upbringing center of Mashikecho from October, 06 to check an effect of this material more. This institution in itself was closed by circumstances in March in the next year, but it is said that excellent kombu grew only to the water tank which I cast same tendencies materials into in large quantities when I look on the last day. Based on this result, Nippon Steel manufactured same tendencies materials by a name called "Beverly". The brand name comes from "ヴィヴァリウム" for the animals and plants garden which reproduced natural environments. The company establishes exclusive research facility "sea laboratory" afterwards in a research institute of Futtsu-shi, Chiba. I assume Tsutsumi leader at group and push forward inspection more. The effect of Beverly spread through the fisherman of each place by the word of mouth and delivered 30 tons in total, "Beverly box" of the boxiness by "the Beverly bag" which a bag was able to checkmate with 28 places of whole country in Nippon Steel for approximately 70 quarters by this summer. But there is the place where seawater damage occurs in the sea area that underwater iron content has abundant, and it is said that the quality of the water investigation is necessary before introduction. I receive the certification as 漁場造成用資器材 which is safe from the association of fishermen's cooperative associations society of the whole country in February, 10, and further use expansion is expected.
