Pulojekiti yoyamba padziko lonse yopangira mafuta a ethanol pogwiritsa ntchito mpweya wotulutsa utsi wa mafakitale wa ferroalloy idayamba kugwira ntchito pa 28 ku Pingluo County, Shizuishan City, Ningxia. Pulojekitiyi ikuyembekezeka kupanga matani 45,000 a mafuta a ethanol ndi matani 5,000 a ufa wa mapuloteni pachaka, zomwe zimapangitsa kuti pakhale phindu la yuan 330 miliyoni, ndikuchepetsa mpweya wa carbon dioxide ndi matani 180,000 pachaka.

Ukadaulo wa kuwiritsa mpweya wotulutsa utsi wa mafakitale kuti upange mafuta a ethanol ndi njira yatsopano ya biotechnology, yomwe ingathandize kugwiritsa ntchito bwino komanso mwaukhondo mpweya wotulutsa utsi wa mafakitale. Ukadaulo uwu ndi wofunika kwambiri pochepetsa mpweya wotulutsa utsi wa carbon, kulowa m'malo mwa mphamvu zakale, kuonetsetsa kuti dziko lonse lili ndi mphamvu ndi chakudya chokwanira, komanso kumanga njira yopezera chuma chobiriwira komanso chopanda mpweya woipa.

Zikumveka kuti kugwiritsa ntchito ukadaulo uwu kungachepetse mpweya wa carbon dioxide ndi matani 1.9 pa tani imodzi ya ethanol yamafuta opangidwa, ndipo kuwonjezera ethanol yamafuta ku petulo kungachepetse bwino kuipitsa kwa utsi wa magalimoto. Nthawi yomweyo, ukadaulo uwu umagwiritsa ntchito zinthu zopanda tirigu, ndipo tani iliyonse ya ethanol yamafuta opangidwa imatha kusunga matani atatu a tirigu ndikuchepetsa kugwiritsa ntchito malo olimapo ndi maekala anayi, zomwe zimathandiza kuonetsetsa kuti chakudya chili bwino.

"Ntchitoyi (yomwe) ili ndi tanthauzo lapadera polimbikitsa makampani opanga ma ferroalloy kuti asinthe njira yogwiritsira ntchito mphamvu zachikhalidwe, kukonza kugwiritsa ntchito bwino zinthu, komanso kugwirizanitsa bwino kuchepetsa ndi chitukuko cha mpweya woipa." Li Xinchuang, Wachiwiri kwa Purezidenti wa China Iron and Steel Association komanso Mlembi wa Komiti Yachipani ya Metallurgical Industry Planning and Research Institute Pamwambo woyambitsa ntchitoyi womwe unachitika tsiku lomwelo, zidanenedwa kuti kuyambitsa ntchito yogwiritsa ntchito mpweya wa mchira wa mafakitale a ferroalloy kuti apange mafuta a ethanol kunali chitukuko chachikulu pakukula kwa kusintha kwa mpweya wochepa wa carbon m'makampani opanga ma ferroalloy.
