Cov cim uas tau lees paub thoob ntiaj teb tuaj yeem pom muaj nyob rau ntawm cov khoom yas hauv ntau lub teb chaws --peb caum tus xub uas mus ncig thiab puag ncig, sib tw sib tw. Tab sis tsis yog txhua yam khoom siv yas nrog lub cim no tuaj yeem siv tau yooj yim. Qhov tseeb, txawm tias qhov tseeb tias cov tshuab siv yas rov ua dua tshiab tau nyob ib puag ncig ntau xyoo lawm, feem ntau ntawm cov pov tseg yas niaj hnub no, tseem xaus rau hauv qhov chaw pov tseg.
Txhua xyoo undersea litter yog txuas ntxiv nce hauv cov xov tooj ceeb toom
Peb tuaj yeem siv cov yas ntau npaum li cas?
Recycling tus nqi sib txawv raws qhov chaw, hom yas thiab daim ntawv thov. Cov kws tshawb fawb kwv yees tias tsuas yog kwv yees li 9 feem pua ntawm tag nrho cov pov tseg yas tsim thoob ntiaj teb yog rov ua dua tshiab. Feem ntau ntawm peb cov khib nyiab yas (txog 79 feem pua) xaus rau hauv qhov chaw pov tseg lossis hauv qhov xwm txheej, thiab kwv yees li 12 feem pua tau raug hlawv.
Vim li cas ho tsis peb rov siv dua yas dua?
Raws li txoj cai, feem ntau cov ntaub ntawv yas tuaj yeem siv dua. Tab sis hauv kev xyaum, recycling ntsib ntau yam teeb meem:
Kev kis kab mob: Cov khib nyiab yas feem ntau muaj cov ntawv lo, cov khoom seem los yog lwm yam khoom. Piv txwv li, muab cov khoom uas tsis yog siv rov ua dua tshiab hauv cov khoom siv rov ua dua tshiab tuaj yeem ua rau cov kwj deg thiab cov khoom siv rov ua dua tshiab puas tsuaj. Qhov no tuaj yeem txo qhov zoo ntawm cov khoom siv rov ua dua tshiab thiab ua rau cov txheej txheem sorting nyuaj. Yog tias cov kwj dej khib nyiab dhau lawm, nws tsuas tuaj yeem siv tsis tau thiab txhua yam raug hloov mus rau qhov chaw pov tseg.
Cov tshuaj phem: Plastics muaj ib tug complex sib tov ntawm cov tshuaj additives uas muab lawv tej yam ntxwv, xws li yooj, ci ntsa iab xim los yog dej kuj. Ntau yam ntawm cov tshuaj no muaj kev phom sij rau tib neeg kev noj qab haus huv. Cov khoom siv yas rov ua dua tshiab uas muaj cov tshuaj phem tuaj yeem cuam tshuam kev noj qab haus huv mus ntev rau cov neeg ua haujlwm, cov zej zog hauv zos thiab cov neeg siv khoom kawg.
Nqis: Muaj ntau txhiab hom yas sib txawv, txhua tus muaj cov khoom tshwj xeeb uas cuam tshuam rau lawv cov qauv, xim thiab cov ntsiab lus melting. Vim tias cov ntaub ntawv no tsis tuaj yeem ua tiav ua ke, kev sau, sib cais thiab pov tseg yog qhov nyuaj thiab kim dua. Piv txwv li, ib qho ntawm cov yas uas muaj ntau tshaj plaws, polyethylene terephthalate (PET), tau hais tias yog 100 feem pua rov ua dua. Txawm li cas los xij, lub raj mis PET ntsuab tsis tuaj yeem rov ua dua nrog lub raj mis PET ntshiab.
Yuav siv cov plastics ntau npaum li cas?
Txhua zaus koj rov siv cov yas, qhov zoo ntawm cov khoom txo qis. Cov tshuaj phem tuaj yeem tsim tau raws li cov khoom sib txawv sib xyaw thaum lub sijhawm rov ua dua tshiab. Yog li ntawd, feem ntau cov yas yog siv dua ib zaug lossis ob zaug ua ntej muab pov rau hauv qhov chaw pov tseg lossis qhov cub. Ntau qhov kev rov ua dua niaj hnub no tsuas yog ncua sijhawm pov tseg zaum kawg es tsis txhob tiv thaiv pov tseg. Kev kis kab mob ntawm cov zaub mov thiab muaj cov tshuaj tsis zoo yog ib qho ntawm cov teeb meem uas cuam tshuam lossis tiv thaiv kev rov ua dua tshiab ntawm cov yas tag nrho.
Cov lej ntawm cov khoom yas txhais li cas?
Ntau yam khoom siv yas tso saib me me ntawm ib thiab xya nyob rau hauv lub cim xub caum. Qhov no yog hu ua resin identification number. Nws tau qhia los ntawm kev lag luam yas hauv xyoo 1980s los txheeb xyuas hom yas siv. Nws tsis qhia tias cov khoom siv rov ua dua tshiab.
Resin Code #1: PET (polyethylene terephthalate)--cov khoom xws li lub raj mis haus lossis cov thawv ntim khoom noj
Resin Code #2: HDPE (High Density Polyethylene)--cov khoom xws li cov jugs mis los yog lub fwj tshuaj ntxuav tes
Resin Code #3: PVC (Polyvinyl Chloride)-- cov khoom xws li cov yeeb nkab lossis cable rwb thaiv tsev
Resin Code #4: LDPE (Low Density Polyethylene)--cov khoom xws li hnab yas lossis cov khoom ntim
Resin Code #5: PP (Polypropylene)--cov khoom xws li yogurt tubs lossis lub raj mis tshuaj
Resin Code #6: PS (Polystyrene)-- cov khoom xws li cov ntawv pov tseg lossis khob
Resin Code #7: Tag nrho lwm cov yas--cov yas uas tsis poob rau hauv pawg dhau los
Dab tsi ntawm cov yas uas siv dua tshiab tshaj plaws?
Cov yas uas muaj tus nqi rov ua dua siab tshaj yog Resin Codes #1 thiab #2. Plastics nrog Resin Codes #3 txog #7 yog qhov nyuaj dua rau kev rov ua dua tshiab, yog li kev rov ua dua tshiab feem ntau tsis muaj peev xwm ua tau zoo. Txhua yam los ntawm lub khob kas fes rau hauv lub thawv ntim thiab yogurt tubs tsis tshua siv dua.
Yuav ua li cas cov yas recycled?
Thaum cov txheej txheem rov ua dua tshiab yuav txawv ntawm qhov chaw, chaw thiab lwm yam, nws feem ntau ua raws li cov kauj ruam no:
Kev Sau: Cov neeg siv khoom muab cov yas tso rau hauv cov thawv rov ua dua tshiab;
Sorting: cov chaw txheeb cov yas los ntawm lwm cov ntaub ntawv los ntawm ntau hom yas;
Ntxuav: cov khoom yog ntxuav thiab qhuav kom tshem tawm cov kab mob;
Reprocessing: cov yas yog hauv av rau hauv cov ntawv nyias, rhuab thiab nias rau hauv cov pellets tshiab;
Kev tsim khoom: pellets yog yaj thiab tsim rau hauv cov khoom yas tshiab.
Dab tsi yog qhov sib txawv ntawm kev rov ua dua thiab downcycling?
Recycling txhais tau tias ua cov khoom siv yas siv rau hauv cov khoom tshiab. Piv txwv li, PET lub raj mis tau muab tso rau hauv cov khoom siv PET pellets. Downcycling, ntawm qhov tod tes, txhais tau tias hloov cov yas rau hauv cov khoom qis dua piv rau cov khoom qub. Qhov no tshwm sim vim hais tias cov qauv molecular hloov thaum lub sij hawm rov ua dua, ua rau ib yam khoom uas tsis haum rau kev ua haujlwm siab. Piv txwv li, tig lub raj mis PET rau hauv qis dua polyester fibers rau khaub ncaws. Niaj hnub no, feem ntau cov txheej txheem piav qhia tias kev rov ua dua tshiab yog qhov txo qis rov ua dua tshiab.
Peb yuav ua li cas?
Kev cia siab rau kev rov ua dua tshiab yuav tsis daws teeb meem plastics. Txawm li cas los xij, muaj ntau cov kauj ruam hauv lub neej ntawm plastics uas tuaj yeem pab daws cov teeb meem plastics thiab tiv thaiv tib neeg txoj kev noj qab haus huv hauv cov txheej txheem, tab sis qhov no feem ntau yuav tsum muaj kev koom tes ntawm txhua tus neeg muaj feem cuam tshuam hauv cov khoom siv plastics. Piv txwv xws li: txo kev siv cov yas tsis tsim nyog; tsim kom pom tseeb thiab traceability ntawm cov tshuaj siv nyob rau hauv plastics; Cov khoom siv yas tsis muaj tshuaj lom: txo qis thiab tshem tawm kev siv cov tshuaj phem hauv cov yas; txwv tsis pub rov ua dua cov yas uas muaj tshuaj lom neeg; simplifying thiab harmonizing cov ntaub ntawv yas; thiab ntxiv dag zog rau Extended Producer Responsibility (EPR).
