重油吸着材マット ｢つれづれ樹｣

　　油を吸着する“杉の樹皮”でできたマットを開発。
　　油を吸着させたマットを、同じ杉樹皮で作った堆肥にまぜて、
　　高温に保つと「自生菌」が油を自然分解し、堆肥になる。
　　流出の重油を完全に分解できた。


　重油流出災害によって　海がおおわれ尽くし
海岸に漂着する
生きものたちが　油まみれになり　
窒息死するもの　衰弱して行くもの
生態系への被害も長期化する。
ニュースされるたんびに　なんとかならないもの
って感じてた。


　有効利用法がなかった“杉の樹皮”
　「常在菌に　重油を自然分解する能力がある」事が見出された。
　杉材樹皮を加工し　重油吸着材を開発
　従来技術の　堆肥製造技術で
　自然分解を促進させれば　重油が分解され　堆肥化もできる。



　杉&檜材には　防虫&抗菌作用がある事は知られてるが、
杉樹皮の常在菌に　重油分解作用があるとは。。。
石炭&石油を作った素材とは　なんだったのでしょうね。
　現在の林業再生の一助として
　この技術は　グローバル化が期待できますね。。。

希望新聞:東日本大震災　杉の樹皮利用の吸着マット　流出の重油を完全に分解
　　　　　　　　　　　　　　　　　　毎日新聞　2013年05月10日　東京朝刊

　東日本大震災で壊れた重油タンクから海に流出した重油を、大分県産業科学技術センターが杉の樹皮を利用した油分解技術でほぼ完全に分解した。分解過程でできる堆肥（たいひ）で野菜も育てたといい、センターの主幹研究員として担当した小谷公人さん（現・農林水産研究指導センター主幹研究員）は「災害廃棄物が無害化できたのは大きい」と話している。
　油回収は従来、化学繊維のスポンジで灯油に混ぜて燃やしていたが、センターは油を吸着する杉の樹皮でできたマットを開発。油を吸着させたマットを、同じ杉樹皮で作った堆肥にまぜて高温に保つと自生菌が油を自然分解し、堆肥になる。二酸化炭素排出量は灯油に混ぜて燃やす従来の手法の３分の１に減り、０６年度にはこの技術で特許を取った。
　１１年９月、センターは岩手県大船渡市沿岸で、海に流出して回収された重油タンクの油約８３０キロを杉樹皮製マットで吸着。堆肥約５０トンに混ぜたところ、５８００ｐｐｍだった油分濃度は８カ月後に検出限界値の５００ｐｐｍ以下になり、１２年１１月末の計測でも濃度は変わらなかったという。　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　【田中理知】

The mat made in the "bark of the Japan cedar" which adsorbs oil is developed. If the mat to which oil was made to stick is mixed with the compost made from the same Japan cedar bark and is maintained at high temperature, a "spontaneous generation bacillus" will carry out natural decomposition of the oil, and will become a compost. Heavy oil of the outflow has been disassembled completely. Heavy oil outflow disaster All the seas are covered and it is washed up on the seashore. It lives and things It becomes 油まみれ. What dying from suffocation The damage to the thing ecosystem which becomes weak and goes is also protracted. To たんび by which news is carried out It was thought that it did not become somehow. "The bark of a Japan cedar" without the effectively using method "It has the ability to carry out natural decomposition of the heavy oil to 常在菌" was found out. A Japan cedar material bark is processed. It is development conventional technology about heavy oil adsorption material. By compost production technology If natural decomposition is promoted Heavy oil is disassembled. Composting is also possible. In Japan cedar & hinoki material Although it is known that an insect control & antibacterial action occurs, it is 常在菌 of a Japan cedar bark. It is that there is heavy oil disintegration. . . material which made coal & oil probably it was . It is this technology as an aid of the present forestry reproduction. Is globalization expectable? . . http://mainichi.jp/feature/news/20130510ddm013040010000c.html The newspaper of choice: Great East Japan Earthquake Adsorption mat of bark use of a Japan cedar Heavy oil of an outflow is disassembled completely. Mainichi Newspapers May 10, 2013 Tokyo morning paper The oil solution technology in which Oita Industrial Research Institute used the bark of the Japan cedar decomposed nearly completely the heavy oil which flowed out of the heavy oil tank broken in the Great East Japan Earthquake into the sea. It says that vegetables were also cultivated with the compost made in a degradation process, and Mr. Kimito Kotani (expression and agriculture-and-forestry fishery research instruction center chief editor researcher) who took charge as a chief editor researcher of a center is saying, "It is large that disaster waste has been detoxicated." Although oil recovery was mixed with kerosene and was conventionally burned by the sponge of the chemical fiber, a center develops the mat made in the bark of the Japan cedar which adsorbs oil. If the mat to which oil was made to stick is mixed with the compost made from the same Japan cedar bark and is maintained at high temperature, a spontaneous generation bacillus will carry out natural decomposition of the oil, and will become a compost. Carbon-dioxide emissions decreased to 1/3 of the conventional technique which is mixed with kerosene and burned, and obtained the patent with this technology in the 06 fiscal year. In September, 11, a center will adsorb about 830 km of oil of the heavy oil tank collected by flowing into the sea on the Ofunato-shi, Iwate coast on the mat made of a Japan cedar bark. When about 50 tons of composts are mixed, the oil concentration which was 5800 ppm is set to 500 ppm or less of a detection limit value in eight months, and it is said that concentration did not change the measurement at the end of November, 12, either.
