Recycled Polyethylene Terephthalate(RPET) tsuas yog cov yas ua los ntawm cov khoom pov tseg PET los ntawm cov lag luam thiab cov neeg siv khoom. Nws tseem yog cov khoom siv feem ntau siv los ntawm cov tuam txhab tsim khoom los pab ua kom tau raws li lawv cov hom phiaj sustainability.
Cov khoom siv rPET yog dab tsi?
rPET sawv raurecycled polyethylene terephthalate. Nws yog ib hom yas ua los ntawm cov yas siv PET, uas feem ntau siv rau ntim thiab ntim khoom noj thiab dej haus. Recycling PET yas txo cov pov tseg thiab txuag cov peev txheej, vim tias nws tuaj yeem ua rau cov khoom tshiab es tsis txhob muab pov tseg.
Dab tsi yog qhov txawv ntawm rPET thiab PET yas?
rPET siv 79 feem pua tsawg dua lub tsev cog khoom emissions thiab tsawg zog dua Virgin PET, thiab muaj nyob rau hauv ib feem peb ntawm cov pa roj carbon hneev taw ntawm Virgin PET. Hauv EU, los ntawm 2025, kev tsim cov fwj tshiab yuav tsum suav nrog tsawg kawg 25 feem pua rPET thiab 90 feem pua ntawm tag nrho cov siv PET yuav tsum tau sau thiab rov ua dua.
PET yog dab tsi?
PET yog luv rau Polyethylene terephthalate. Kuj tseem hu ua tus naj npawb yas 1 hauv cov yas resin code, koj tuaj yeem txheeb xyuas nws los ntawm tus lej 1 hauv cov cim cim npe.
PET yog tsim los ntawm cov roj av thiab cov nkev ntuj. Cov fossil fuels no tau muab rho tawm los ntawm lub ntiaj teb siv ntau lub zog thiab cov peev txheej. Tom qab ntawd nws raug thauj mus rau qhov chaw ua haujlwm uas tsim cov polymers.
Polymers yog cov molecules loj ua los ntawm cov saw ntev ntawm cov me me molecules hu ua monomers. Qhov ntev thiab hom monomer yog dab tsi muab txhua cov yas nws cov khoom.
Yog vim li cas peb siv PET yas ntau heev yog tias nws yog cov khoom siv ntau yam. Ua ntej, nws yog cov thermoplastic, uas txhais tau hais tias thaum cua sov, nws tau muag muag, ua rau nws yooj yim dua los siv hauv cov khoom tshiab. Nws kuj yog lub teeb yuag, muaj kev tiv thaiv zoo rau cov tshuaj, muaj zog, ruaj khov, nyab xeeb siv, thiab tuaj yeem siv tau yooj yim.
Ib qho ntawm lub zog tseem ceeb ntawm PET, nws cov kav ntev, kuj yog nws qhov teeb meem loj tshaj plaws. Nws tuaj yeem siv sijhawm ntau dua 700 xyoo rau PET kom tawg hauv qhov chaw pov tseg.
