Kev lag luam thoob ntiaj teb niaj hnub no xav tau kev siv cov khoom siv ua tau zoo thiab kev txuag cov khoom los ntawm kev siv dua tshiab thiab rov ua dua tshiab Qhov nruab nrab, cov khoom siv tooj liab muaj 35% cov ntsiab lus rov ua dua tshiab, uas txo cov pa roj carbon ntau ntawm cov tooj liab. Tsis zoo li lwm yam khoom lag luam xws li lub zog lossis khoom noj, tooj liab tsis tau siv.
Vim tias tooj liab tsis poob nws qhov kev tshwm sim thaum lub sij hawm rov qab siv dua, nws tuaj yeem siv rov ua dua nyob rau hauv tib cov kev ua tau zoo.
Tooj liab yog ib qho ntawm ob peb cov ntaub ntawv uas tuaj yeem siv rov ua dua tsis tas yuav poob qhov kev ua tau zoo. Tsis muaj qhov sib txawv hauv qhov ua tau zoo ntawm cov tooj liab zoo (theem thib ob) thiab mined tooj liab (thawj qhov khoom lag luam), yog li lawv tuaj yeem siv sib pauv hloov. Kev rov qab ua haujlwm tuaj yeem txuag cov roj carbon dioxide thiab lub zog. Kev rov siv tooj liab yog ib txoj hauv kev rau ib puag ncig kom rov luam tau cov khoom muaj txiaj ntsig rau kev lag luam. Kev rov siv tooj liab yuav tsum 80% -90% lub zog tsawg dua thawj kev tsim khoom.
Rau kev rov ua dua tshiab kom ua tau zoo, kev tsim kho tshiab yog xav tau. Kev siv zog los txhawb kev rov ua dua tshiab tuaj yeem siv hauv kev tsim cov khoom tshiab los txhawb txoj sia thim rov qab thiab kev ua haujlwm thim rov qab thiab kev ua haujlwm tag nrho. Ib qho ntxiv, txoj cai tswjfwm yuav tsum tau txhawb nqa kev rov ua haujlwm thiab cov khoom lag luam, ntawm qib kev lag luam thiab qib ntawm cov pej xeem.
Cov nplua nuj feem ntau (70%) ntawm tooj liab yog siv rau hauv cov ntawv thov kawg vim tias nws yog qhov ua tau zoo tshaj plaws tsis muaj nqi kub thiab tus nqi hluav taws xob. Yog li tej yam uas muaj tooj liab ua hauj lwm tau zoo dua.
Tooj liab hauv lub tshuab fais fab tuaj yeem txuag tau 100 txog 7,500 tons ntawm cov pa roj carbon dioxide thiab txuag cov neeg siv 25 txog 2.5 lab nyiaj daus las hauv cov nqi hluav taws xob.
Cov hluav taws xob zoo thiab kev ua tau zoo ntawm tooj liab yog lub hauv paus ntawm kev siv hluav taws xob. Tooj liab yog qhov ua tau zoo tshaj plaws uas tsis tiv tauj cov cua sov thiab hluav taws xob, yog li cov khoom muaj tooj liab zoo li ua haujlwm ntau dua. Cov nplua nuj feem ntau (70%) ntawm tooj liab yog siv rau cov ntawv thov kawg, uas tau txais txiaj ntsig los ntawm nws cov kev ua haujlwm siab.
Kev txuag hluav taws xob yog qhov tseem ceeb uas txhawb kev txhim kho kom ruaj khov thiab kev lag luam ntxiv mus. Ntau yam tsim nyog uas txhais tau qhov zoo ntawm lub neej niaj hnub xav tau lub zog, uas ua rau lub zog hluav taws xob / kev ruaj ntseg yog qhov tseem ceeb rau kev tsim kho kom ntev mus ntev. Kev txhim kho lub zog siv hluav taws xob pab tib neeg kom txo kev siv nyiaj rau lub zog hluav taws xob tshiab muaj peev xwm thiab txwv qhov tsis txaus siab ntawm kab sib chaws.
Ntxiv rau qhov ua kom zoo rau ib puag ncig, kev rov ua cov tooj liab seem (xws li cov khoom siv hluav taws xob pov tseg) kuj tuaj yeem ua rau cov khoom siv rov ua ntau yam hlau, xws li kub, nyiaj, nickel, tin, txhuas, thiab zinc.
Tsuas yog nyiaj, tooj liab muaj qhov siab tshaj plaws ntawm txhua cov hlau. Cov yeeb yam no ua rau tooj liab yog cov khoom siv tseem ceeb rau kev xaiv hluav taws xob thiab kev xa tawm (45% ntawm kev siv) -saib kev xa hluav taws xob mus rau cov tsev thiab lag luam. Cov khoom siv hluav taws xob uas muab cov hluav taws xob, cov kab thiab kev sib cuag rau cov khoom siv hluav taws xob thiab cov neeg siv khoom siv hluav taws xob nyob rau 12,5% ntawm kev siv tooj liab, thiab tshuav 12.5% siv rau hauv kev thauj mus los. Lub siab-ntshiab tooj liab thaiv cov kab ua haujlwm hauv tsheb ciav hlau, tsheb, lossis tsheb thauj khoom hloov chaw tam sim no los ntawm lub roj teeb mus rau ntau qhov chaw ntawm lub tsheb, xws li lub teeb, lub ntsuas phoo nruab nrab, on-board computers, thiab satellite navigation system.
Lwm 20% tooj liab tau siv rau hauv cov tsev xa dej, ru tsev thiab thawb tawm. Tooj liab muab lub teeb, ruaj, tu-dawb qauv, yog ib txwm saib zoo, ruaj thiab siv tau dua tshiab. Qhov seem 10% yog siv rau npib nyiaj, duab puab, hniav nyiaj hniav kub, cov khoom siv suab paj nruas, khoom siv ua noj thiab lwm yam khoom siv.
Qhov peev txheej tooj liab loj no suav nrog ntau qhov kawg ntawm kev siv, sib npaug rau cov pa tawm hauv thaj tsam 30 xyoo dhau los, thiab feem ntau hu ua" hauv nroog mine" ntawm zej zog.
Kev rov qab ua haujlwm tsis tsuas yog pab cov kev xav tau txhua xyoo rau kev ua haujlwm tooj liab, tabsis tseem txuag cov khoom muaj nqis zoo, txuag hluav taws xob, thiab txo cov pa carbon dioxide tawm.
