Cov ntsiab lus ntawm cov yas (rau ntim khoom noj & haus): lawv txhais li cas rau peb txoj kev noj qab haus huv?
Plastics tej zaum yuav yog cov khoom siv polarizing tshaj plaws ntawm lub sijhawm niaj hnub no. Nws muab cov txiaj ntsig zoo kawg uas pab peb txhua hnub. Yas kuj siv ntau hom khoom noj & haus ntim ntim. Lawv pab tiv thaiv cov khoom noj los ntawm kev puas tsuaj. Tab sis koj puas paub cov ncauj lus kom ntxaws txog qhov sib txawv ntawm cov yas? Lawv txhais li cas rau peb kev noj qab haus huv?
● Dab tsi yog cov khoom sib txawv ntawm cov yas siv hauv cov khoom noj & haus ntim khoom?
Tej zaum koj yuav pom tus naj npawb 1 txog 7 nyob rau hauv qab lossis sab ntawm lub thawv ntim yas. Tus lej no yog cov yas "resin ID code," tseem hu ua "recycling tooj." Tus lej no tseem tuaj yeem muab kev taw qhia rau cov neeg siv khoom uas xav rov ua dua cov thawv yas.
● Tus lej ntawm cov yas txhais li cas?
Resin Identification Code lossis tus lej rov ua dua tshiab ntawm cov yas qhia txog hom yas. Ntawm no peb xav qhia cov ntaub ntawv ntau ntxiv txog cov khoom siv uas siv ntau tshaj plaws hauv cov khoom noj & haus ntim khoom, muaj nyob rau ntawm Society of Plastics Engineers (SPE) thiab Plastics Industry Association (PIA):
PETE lossis PET (Recycling tooj 1 / Resin ID Code 1
HDPE (Recycling tooj 2 / Resin ID Code 2)
PVC (Recycling tooj 3 / Resin ID Code 3)
LDPE (Recycling tooj 4 / Resin ID Code 4)
PP (Recycling tooj 5 / Resin ID Code 5)
PS (Recycling tooj 6 / Resin ID Code 6)
Lwm yam los yog O (Recycling tooj 7 / Resin ID Code 7)
Cov no yog ntau hom yas uas peb ntsib. Qhov no yog cov ntaub ntawv yooj yim heev ntawm cov ncauj lus uas ib tus tuaj yeem siv sijhawm ntau lub hlis rau kev tshawb fawb. Yas yog cov khoom siv nyuaj, ib yam li nws cov khoom tsim, kev faib tawm thiab kev siv. Peb txhawb kom koj dhia dej tob tob kom nkag siab txog tag nrho cov kev nyuaj no, xws li cov khoom yas, kev rov ua dua tshiab, kev phom sij rau kev noj qab haus huv thiab lwm yam, nrog rau qhov zoo thiab qhov tsis zoo ntawm bioplastics.
