Tus nqi ntawm cov yas ntim khoom yog ze li ntawm plaub lub sij hawm zoo tshaj nrog lwm cov ntaub ntawv qhia.
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Txoj kev lag luam plastics tsis ntev los no tau ntsib cov kev sib tsoo ntawm tej nqi hluav taws uas muaj feem xyuam rau kev tsim thiab siv cov khoom yas. Tab sis ib txoj kev tshawb nrhiav tau pom tias qhov nqi ntawm kev siv cov hnab yas yog kwv yees li ntawm plaub zaug zoo tshaj nrog lwm cov khoom siv.
Cov kev tshawb fawb los ntawm Trucost hauv Tebchaws Meskas, "Plastics and Sustainability: A Measure to Continuously Improve Environmental Benefits, Cost and Opportunities" yuav ntxiv cov kev tshawb fawb ntawm United Nations Environment Program hauv xyoo 2014, siv tib txoj kev tshawb fawb. Thiab qhov "peev nyiaj peev txheej" qhia tau.
Trucost kwv yees tias cov yas lwm yam xws li iav, tin los yog aluminium yuav ntxiv $ 139 nais nyiaj mus $ 53 nphom hauv nqi, nrog rau cov khib nyiab marine, kev tswj lub neej kawg, kev thauj mus los, kev tsim khoom, cov khoom siv thiab cov khoom siv dua thiab kev cuam tshuam.
Feem ntau, cov kws tshawb fawb tau hais tias tus nqi ntawm ib kilogram ntawm lwm cov ntaub ntawv yog tsawg dua tus nqi ntawm ib plhom ntawm cov yas. Txawm li cas los xij, cov ntaub ntawv no yuav tsum muaj nruab nrab ntawm ntau tshaj plaub zaug qhov nyhav kom tiav cov khoom ntawm cov yas. Piv txwv li, 30 gram yas haus dej haus yuav tsum tau 141 grams khob los yog txhuas.
Qhov kev qhia tshiab no yog commissioned los ntawm American Chemistry Council. Steve Russell, tus thawj tswj hwm ntawm lub koom haum ntawm lub koom haum, said, "Cov ntaub ntawv hais txog plaub zaug yog ib qho kev xav tsis zoo.
Russell hais tias txoj kev tshawb no yog qhov tseeb uas yuav muaj teeb meem, tab sis nws yog ib qho tshiab ntawm kev sib tham txog kev ruaj ntseg hauv kev lag luam.
Tsis tas li ntawd, daim ntawv tshaj tawm qhia txog cov theem pib los txo cov nqi tag nrho ntawm tag nrho kev lag luam los ntawm kev nce $ 4,1 billion, nrog rau:
Nce lub zog cua, hnub ci thiab hydropower siv hauv plastics ntau ntau yuav tsum txo cov kev pab cuam los ntawm cov nqi ntawm $ 7.6 billion.
Txo kev siv cov khoom siv hauv cov khoom noj, dej haus thiab dej khov ntim cov dej khwv tau los ntawm 30% tuaj yeem txo cov nqi ntawm $ 7.3 billion.
Yog tias cov roj tsheb tsis zoo ntawm cov tsheb thauj khoom yas thiab cov khoom yas tau nce li ntawm 20%, qhov nqi thaj tsam ntawm $ 10.6 billion yuav txo.
Tsis zoo li tus neeg siv nruab nrab, cov tuam txhab thiab cov neeg tsim cai yuav tsum saib cov nqi khoom ntawm cov khoom yas los ntawm kev pom dav thiab tham nrog ntau cov ntaub ntawv.
"Cov khoom lag luam tau ua rau hnov cov lus tsis zoo ntawm cov khoom yas Cov kev tshawb fawb no tau muab qhov kev tshawb fawb pom tias cov khoom uas muaj teeb meem rau lub chaw los yog lwm cov ntaub ntawv yuav tsum tau siv Yog tias peb xav txiav txim siab zoo tshaj plaws txog lub ntiaj chaw thiab qhov chaw, txhua yam yuav tsum tau xav txog. Qhov no yog qhov tseem ceeb ntawm qhov kev tshawb fawb no. "
