Sustainability tau dhau los ua qhov tseem ceeb hauv PET preform ntau lawm, nrog rau cov tuam txhab siv ntau lub tswv yim los txo lawv cov hneev taw ib puag ncig. Ib qho ntawm cov qauv tseem ceeb yog kev siv cov PET rov ua dua tshiab (rPET) hauv cov txheej txheem ntau lawm.
Los ntawm kev sib koom ua ke rPET, cov tuam txhab tuaj yeem txo qis kev noj cov yas yas, txo qis cov pa tawm hauv tsev cog khoom, thiab txhawb kev lag luam ncig. Tsis tas li ntawd, kev nce qib hauv kev siv thev naus laus zis tau ua rau tsim cov PET preforms nrog cov phab ntsa nyias, txo cov khoom siv tsis muaj kev cuam tshuam lub zog thiab kav ntev.
Lwm qhov tseem ceeb tshaj plaws yog kev txhim kho bio-based PET, muab los ntawm cov khoom siv txuas ntxiv dua tshiab xws li cov nroj tsuag biomass, uas muaj lwm txoj hauv kev ruaj khov rau cov roj av ib txwm muaj.PET preform. Tsis tas li ntawd, cov tuam txhab lag luam tau nqis peev hauv cov tshuab hluav taws xob txuag hluav taws xob thiab siv cov khoom siv hluav taws xob txuas ntxiv mus kom txo tau lawv cov pa roj carbon monoxide. Cov qauv kev ruaj ntseg no tsis yog tsuas yog hais txog kev txhawj xeeb ib puag ncig nkaus xwb tab sis kuj ua tau raws li cov neeg siv khoom xav tau ntau ntxiv rau cov kev daws teeb meem hauv eco-phooj ywg.
