Piv nrog cov thawv yas, tus nqi siab dua ntawm aluminium foil noj su lub thawv yog ib qho laj thawj tseem ceeb. Nws yog to taub tias tus nqi ntawm polystyrene noj su lub thawv tsuas yog ob peb xees, thaum ib tug {{{0}}gram aluminium foil su box muag rau 0.80 yuan. Txawm tias tom qab txiav tawm tus nqi rov ua dua ntawm 0.22 yuan txhua, tus nqi tiag tiag ntawm txhua lub thawv ntawv txhuas txhuas yog siab li 0.58 yuan, ntau zaus ntau dua li lub thawv noj su polystyrene. Peb ntseeg hais tias dab tsi yog xam ntawm no tsuas yog ib tug nyiaj txiag account, thiab nws yog ib tug heev nyiaj txiag account. Peb yuav tsum tsis txhob siv cov tshuaj lom vim lawv pheej yig thiab ua rau peb tus kheej muaj kev tua tus kheej ntev. Lwm qhov laj thawj tseem ceeb vim li cas peb txhawb nqa kev siv aluminium foil noj su lub thawv yog qhov "recyclable" yam ntxwv ntawm txhuas.
Cov yam ntxwv ntawm "daim ntawv thov rov ua dua tshiab" yog qhov tseem ceeb ntawm kev rov ua dua tshiab ntawm aluminium foil noj su lub thawv, uas muaj txiaj ntsig zoo rau kev txuag cov peev txheej thiab txo cov pa phem ib puag ncig. "Recyclable application" yog ib qho tseem ceeb ntawm txhuas. Feem ntau, txhuas tuaj yeem rov ua dua mus txog nees nkaum tsib zaug, nrog rau kev pabcuam lub neej ntawm ob mus rau peb puas xyoo, thiab kev tsim cov khoom siv aluminium tuaj yeem txuag tau ntau lub zog siv. Kev tsim khoom ntawm ib tuj ntawm electrolytic aluminium yuav tsum muaj qhov nruab nrab ntawm 14,500 kilowatt teev ntawm hluav taws xob, thiab kev tsim ib tuj ntawm cov khoom siv rov ua dua tshiab tsuas yog 5% ntawm lub zog siv los tsim ib tuj ntawm electrolytic txhuas. Nyob rau tib lub sijhawm, cov pa roj carbon dioxide emissions yog ntau dua 90% qis dua li cov khoom ntawm electrolytic aluminium.
Tsis tas li ntawd, piv nrog cov kev hloov geological tshwm sim los ntawm "dawb paug", aluminium su lub thawv tuaj yeem huab cua tom qab muab tso rau hauv cov av rau ob mus rau peb lub xyoos, thiab yuav tsis ua rau muaj kev puas tsuaj los yog cog cov khoom hloov pauv rau hauv av. Qhov tseeb, hais txog tus nqi ntawm kev siv, cov nqi siab tam sim no kuj tuaj yeem hloov pauv los ntawm kev txhawb nqa cov khoom siv. Yog tias qhov ntsuas kev tsim khoom nce mus txog ntau dua 10, 000 daim ib hnub, nqi xauj tsev, kev siv zog thiab kev siv hluav taws xob tuaj yeem txo, uas tuaj yeem nqus tau ib feem ntawm cov nqi siab dua. Txij li kev rov ua dua tshiab ntawm aluminium foil noj su lub thawv tuaj yeem txaus siab rau tsoomfwv cov nyiaj pab, tag nrho cov nqi tsis siab dua li cov thawv noj su. Yog li ntawd, qhov tseem ceeb tseem yog qhov teeb meem ntawm lub tswv yim. Yog tias peb pib los ntawm qhov kev xav ntawm "kev hlub ntawm lub neej", nws yuav yooj yim dua los txhawb kev siv aluminium foil noj su lub thawv.
