Thaum Lub Peb Hlis 12, Beijing lub sijhawm, raws li kev tshaj xov xwm txawv teb chaws, cov khib nyiab rov qab tsis ib txwm muab lub neej tshiab rau cov khoom yas, ntawm qhov tsis tooj, tib neeg tau maj mam dhau los ua cov yas .
Raws li kev txheeb cais los ntawm Asmeskas Kev Tiv Thaiv Ib Puag Ncig, 35,4 lab tons ntawm cov yas tau tsim hauv Teb Chaws Asmeskas xyoo 2017. Yog tias tib neeg xav txo yas muaj kuab paug, kev rov ua dua tshiab tej zaum yuav daws tau yooj yim. Tab sis dab tsi tshwm sim thaum koj ntxuav cov thawv yas no thiab hliv rau hauv cov khoom coj mus ua dua tshiab?
Hmoov tsis, qhov kawg ntawm kev rov ua dua tshiab yas tsis yooj yim raws li ntau tus neeg xav, John hosewar, tus kws paub txog tsiaj txhu roj av ntawm Greenpeace Raws li Hocevar), kev rov ua dua tshiab tsis zoo li yuav muab lub neej tshiab rau cov khoom yas. Qhov tseeb, tsuas 8,4% ntawm cov yas khib nyiab rov qab thaum kawg. Nws tsis yog tias cov neeg siv khoom siv tsis ua thawj coj los siv lossis lawv tsis siv cov khoom siv rov ua dua tshiab, tab sis tsis muaj cov ntsiab lus sib luag rau cov khoom siv rov qab yas hauv Tebchaws Meskas.
"Nyob rau hauv feem ntau ntawm Tebchaws Meskas, cov khoom siv yas ntau yog cov khoom siv tsis tau rov qab siv tau," feem ntau yog faus lossis hlawv.
Nws yuav tsum raug sau tseg tias tsis yog txhua txhua cov khoom yas yog tib yam. Yog tias koj saib rau hauv qab ntawm cov pob tshab yas pob tshab (xws li lub raj mis yas rau khoom noj thiab ntxuav hmoov), koj yuav pom tias muaj ntau tus lej nyob hauv daim duab peb sab ua cim rov ua dua tshiab. Yog tias tus lej yog "1", nws txhais tau tias yas khib yog ua los ntawm cov khoom siv hu ua polyethylene terephthalate (PET); qee qhov yog impermeable Lub raj mis yas ntshiab (piv txwv li, lub raj mis yas rau mis nyuj). Tus lej hauv daim duab peb sab yog "2", uas txhais tau tias ua los ntawm high-ntom polyethylene (HDPE). Hauv cov ntawv cog qoob loo pov tseg, cov khib nyiab yas tau faib raws li cov lej cim (7 tus naj npawb hauv tag nrho), uas qhia tau tias rov ua dua tshiab ntawm cov yas.
Kara pochiro, tus thawj coj ntawm lub koom haum yas rov qab hais tias qhov khoom siv yas 1 thiab 2 tuaj yeem rov ua dua tshiab. Cov khib nyiab yas yog tws, yaj rau hauv pob, thiab tom qab ntawd muag rau cov tuam ntxhab rau kev luam tawm. Lub hnab yas siv rov qab tuaj yeem siv los ua cov ntaub pua plag, khaub ncaws, ntim khoom yas thiab lwm yam khoom.
Nws kuj tau taw qhia tias qhov nyuaj dua nws yog kev rov qab siv cov khoom yas nrog cov qib siab dua. Raws li kev txheeb cais ntawm Greenpeace, hom yas pov tseg no muaj 69 feem pua ntawm peb cov yas siv niaj hnub. Nws raug nqi ntau dua thiab siv hluav taws xob ntau dua los ua kom pov tseg ntawm lawv tshaj li pov tseg ntawm No. 1 thiab No. 2 khoom lag luam yas. Ob peb xyoos dhau los, ntau lub koomhaum rov qab siv nyob hauv Tebchaws Meskas tau muag cov khoom yas sib xyaw rau cov tebchaws Esxias, tab sis ob xyoos dhau los, cov tebchaws no tau txwv tsis pub cov khoom ntim yas txawv teb chaws tuaj.
Vim li no, cov koom haum sau khib nyiab yuav tsum tau siv cov chaw khib nyiab tshiab, tab sis feem ntau ntawm kev sim tsis ua tiav. Piv txwv, Los Angeles lub chaw pov tseg khib nyiab tseem tsis tuaj yeem tuav cov hnab yas khib nyiab muaj qib siab dua 2. Xyoo 2019, Tus Saib Xyuas Xov Xwm tau hais tias qee lub koom haum pov tseg khib nyiab pov tseg cov khib nyiab mus rau hauv chaw pov khib nyiab lossis chaw kub nyhiab.
Boccio taw qhia tias tam sim no lub teb chaws Asmeskas xav tau dab tsi yog qhov chaw kho rau lwm hom plastics. Tab sis hoshawar envisions cov kev daws teeb meem sib txawv: cov lus teb yooj yim tshaj plaws yog tias peb yuav tsum tsis txhob ua ntau yam uas siv tau. Hauv lwm lo lus, puas yas khoom rov qab puas ua rau lub siab? Txog No.1 lossis No.2 lub raj mis yas, cov lus teb yog "yog", tab sis ntau thiab ntau dua cov khoom yas nrog No.5 daim ntawv lo yog rov ua dua tshiab. Nws yog hom ntawm cov yas hloov tau yooj yim, suav nrog cov hauv thawv yoghurt. Nws yog ib qho tseem ceeb heev uas yuav tau kuaj xyuas qhov txwv thiab txoj cai ntawm kev rov ua haujlwm hauv zos rau lwm qib ntawm cov khoom yas.
Hosewar cov lus teb tau yooj yim dua: rau cov yas 3, 4 thiab 5, tus nqi them rov qab yog siab dua, thiab qhov zoo yog feem ntau ntau dua ntawm qhov tsis zoo.
