Txhawm rau txhim kho cov roj kev lag luam ntawm cov tsheb sib txuas sab hauv (ICEV) thiab kev caij nkoj ntawm cov tsheb hluav taws xob (BEV), kev lag luam tsheb tau nquag nrhiav kev daws teeb meem rau ntau lub cev, chassis thiab lub zog hluav taws xob. Nyob rau hauv xyoo tas los no, maj mam nce nyob rau hauv qhov kev faib ua feem ntawm aluminium structural qhov chaw ntawm cov neeg nrog caij tsheb tau coj ib tug paradoxical qhov teeb meem rau ib puag ncig sustainability: ntawm ib sab, ib tug loj tus naj npawb ntawm lub teeb yuag aluminium-raws li cov ntaub ntawv yuav txo tau lub tsev xog paj emissions thaum siv tsheb; Txawm li cas los xij, cov khoom siv aluminium ntau dua yog siv, qhov siab dua cov pa roj carbon hneev taw ntawm cov chaw tsim khoom tsheb. Qhov no yog vim hais tias automotive aluminium structural seem yog tsim los siv electrolytic thawj txhuas, thiab qhov nruab nrab carbon hneev taw ib tuj ntawm electrolytic thawj txhuas yog li ntawm 12 - 16.5 tons ntawm carbon sib npaug (piv rau daim duab no rau steelmaking uas tsuas yog hais txog. 2.2 tons).
Txhawm rau rhuav tshem qhov teeb meem no, ib qho kev daws teeb meem yog siv cov khoom siv tom qab siv cov khoom siv txhuas (feem ntau hu ua cov khib nyiab qub) los hloov cov electrolytic thawj txhuas los tsim cov khoom siv txhuas alloy. Remelting recycled aluminium rau hauv aluminium ingots siv tsawg dua 7 feem pua ntawm lub zog siv los ntawm electrolytic thawj txhuas, thiab tuaj yeem txo cov pa roj carbon emissions ntau dua 90 feem pua.

Hauv kev lag luam tsheb, ib qho ntawm cov teeb meem tseem ceeb rau kev siv tam sim no ntawm cov neeg siv khoom siv rov qab siv txhuas yog qhov hloov pauv loj hauv cov khoom seem thiab qib siab ntawm impurity ntsiab vim tsis paub qab hau rov ua dua tshiab. Kev lag luam thiab kev kawm tau ua hauj lwm los tsim cov txheej txheem pov tseg thiab kev ua ntej kom tau txais cov khoom pov tseg nrog cov khoom siv nqaim thiab cov ntsiab lus tsis zoo rau kev tshem tawm cov ntawv thov rov ua dua tshiab. Txawm li cas los xij, tsim kom muaj kev nthuav dav thiab paub tab hauv lub sijhawm luv mus rau nruab nrab zoo li tsis zoo li. Tsis tas li ntawd, cov nqi siab uas cuam tshuam nrog kev siv cov kev sib cais thiab cov txheej txheem ua ntej yuav txo qis kev lag luam ntawm kev siv cov khoom seem.
