Hnub luam tawm: Lub Rau Hli 27, 2025
Tawm tsam cov backdrop ntawm cov pa roj carbon-nruab nrab cov lus cog tseg, kev tsim khoom siv kom ruaj khov tau dhau los ua cov galvanizing kev lag luam qhov tseem ceeb tshaj plaws. Nyob rau hauv lub lim tiam tsis ntev los no, ntau tus steelmakers tau dov tawm eco-phooj ywg galvanized steel daws tau tsim los mus luaj emissions thiab txhawb cov peev txheej thiab txhawb cov peev txheej.
ArcelImittal's Netherlands nroj tsuag tau pom tias "xoom-emission" kub-dip galvanizing los ntawm hydrogen boilers thiab lub hnub ci photovoltaics. Txawm hais tias peev txheej, lub kaw lus txiav carbon tso zis los ntawm 12,000 tonnes hauv ib xyoos rau nws cov khoom lag luam steel galvanized, xa cov khoom ntev ntev
Nyiaj txiag thiab ib puag ncig cov txiaj ntsig.
Posco ntawm Kaus Lim Qab Teb, lub sijhawm ntawd, cov hlaws tsis muaj roj los ntawm cov roj av me me rau ob qho kub kub galvanizing chav dej thiab kho cov txheej txheem pov tseg. Raws li nws 2025 Daim Ntawv Tshaj Qhia Txog Kev Seev Cev, Posco cov ntawv pov thawj Galvanized Steel tam sim no emits 22% tsawg dua rau ib chav thiab rov qab siv 78% ntawm nws cov txheej txheem dej.
Hauv North America, US Steel thiab MIT tau sib koom tes ntawm "Ntse Galvanizing Cog" teg ua ke, kev ntsuas cov ntaub ntawv thiab cov ntaub ntawv loj rau kev ua kom cov kab ntawm lub sijhawm tiag tiag. Los ntawm kev saib xyuas da dej kub, coil ceev, thiab tshuaj lom neeg ntau,}}}}}} thiab lub zog ua haujlwm los ntawm 12%.
Ntawm tus neeg yuav khoom, "Daim ntawv pov thawj ntsuab" tau dhau los ua kev lag luam tshiab. Lub Koom Haum Ntiaj Teb Hlau Kev "Ntsuab Galvanized"Daim ntawv yuav tsum muaj kev taug kev carbon monoxidea nyob rau hauv 1.5 tco₂e per tonne. Tshaj li 50 tuam txhab ntug hauv European thiab North Asses neeg hluas nkauj.
Kom meej meej, kev siv pov thawj loj thiab muaj ntawv pov thawj eco-eco tau rov kho cov av hlau galvanized, yuam cov kev sib tw los ua kom muaj kev ua tau zoo ntawm ib puag ncig thiab tus nqi.
