Dab tsi yog Cov Plastics Siv Ib Leeg thiab Yuav Tsum Tau Txwv?
Thaum Lub Rau Hli 2021, Pawg Saib Xyuas tau tshaj tawm cov lus qhia ntawm SUP cov khoom lag luam kom ntseeg tau tias cov kev cai ntawm cov lus qhia raug siv kom raug thiab sib npaug thoob plaws EU. Cov txheej txheem qhia meej cov ntsiab lus tseem ceeb siv hauv cov lus qhia thiab muab cov piv txwv ntawm SUP cov khoom poob rau hauv lossis sab nraud nws cov peev txheej.
Thaum Lub Ib Hlis Ntuj xyoo 2020, Tuam Tshoj tau koom nrog ntau dua 120 lub teb chaws cog lus tias yuav txwv tsis pub siv cov yas ib zaug. Lub teb chaws ntawm 1.4 billion tus pej xeem yog tus thib 1 tsim cov khoom pov tseg yas hauv ntiaj teb. Nws tau nce txog 60 lab tons (54.4 lab metric tons) hauv 2010 raws li tsab ntawv ceeb toom lub Cuaj Hlis 2018 hu ua "Plastic Pollution."
Tab sis Tuam Tshoj tau tshaj tawm tias nws npaj yuav tawm tsam kev tsim khoom thiab muag cov hnab uas tsis muaj degradable los ntawm qhov kawg ntawm 2020 hauv cov nroog loj (thiab txhua qhov chaw los ntawm 2022), nrog rau cov straws siv ib zaug thaum xyoo 2020. Kev lag luam muag khoom yuav muaj txog 2025 rau ua raws li.
Kev thawb kom txwv cov yas coj mus rau theem nruab nrab hauv 2018 nrog kev txhawb nqa loj xws li qhov khoom plig tau txais txiaj ntsig #StopSucking, uas muaj cov hnub qub zoo li NFL quarterback Tom Brady thiab nws tus poj niam Gisele Bündchen thiab Hollywood tus neeg ua yeeb yam Adrian Grenier cog lus tias yuav tso cov yas siv ib zaug. Tam sim no lub teb chaws thiab tuam txhab uas muag tau hais tias tsis muaj plastics los ntawm kaum ob, thiab cov neeg siv khoom tau ua raws nrog lawv.
Raws li cov yas-txhais txwv kev txav mus rau qhov tseem ceeb tshaj plaws - xws li Tuam Tshoj cov lus tshaj tawm tshiab tshaj plaws - peb tau txiav txim siab los txhais lub hwj, hnab thiab cov straws uas ua rau lub ntiaj teb no do.

Ib leeg-siv yas yog dab tsi?
Muaj tseeb rau nws lub npe, cov yas siv ib zaug yog cov yas pov tseg uas tau tsim los siv ib zaug ces pov los yog rov siv dua. Qhov no suav nrog txhua yam los ntawm cov raj mis dej haus thiab tsim cov hnab rau cov yas yas pov tseg thiab cov hlua yas - tiag tiag cov khoom yas uas koj siv ces muab pov tseg tam sim ntawd. Thaum cov khoom no tuaj yeem rov ua dua tshiab, Megean Weldon ntawm blog thiab khw muag khoom pov tseg Zero Waste Nerd hais tias tsis yog qhov qauv.
"Qhov tseeb, tsawg kawg cov khoom yas tuaj yeem ua tiav rau hauv cov ntaub ntawv tshiab thiab cov khoom lag luam," nws hais hauv email. "Tsis zoo li iav thiab txhuas, yas tsis ua rau tib yam khoom nws yog thaum nws tau sau los ntawm lub chaw rov ua dua tshiab. Qhov zoo ntawm cov yas yog downgraded, yog li nws thiaj li, thiab inevitably, cov yas yuav tseem mus rau hauv qhov chaw pov tseg. "
Nqa ib lub raj mis dej yas. Feem ntau cov fwj hais tias lawv tuaj yeem rov ua dua - thiab tsuas yog ua raws li lawv cov khoom siv tau yooj yim rov ua dua polyethylene terephthalate (PET), lawv tuaj yeem ua tau. Tab sis ze li ntawm xya tawm ntawm 10 lub raj mis xaus rau hauv qhov chaw pov tseg lossis pov tseg li khib nyiab. Qhov teeb meem no tau nce ntxiv thaum Tuam Tshoj tau txiav txim siab tsis lees txais thiab rov ua cov yas yas hauv xyoo 2018. Rau cov nroog, uas txhais tau tias kev rov ua dua tshiab tau nce nqi ntau dua, raws li Lub Atlantic, ntau lub nroog tam sim no tsuas yog xaiv rau kev siv nyiaj txiag pov tseg hauv kev rov ua dua tshiab.
Ua ntej txoj hauv kev pov tseg no nrog lub ntiaj teb kev siv cov yas uas niaj hnub loj hlob - tib neeg tsim yuav luag 20,000 lub raj mis yas ib ob, raws li Tus Saib Xyuas thiab Asmeskas cov khib nyiab loj hlob los ntawm 4.5 feem pua los ntawm 2010 txog 2015 - nws tsis muaj qhov xav tias lub ntiaj teb yog cov khoom pov tseg yas. .

Yas tuaj yeem muaj sia nyob peb txhua tus
Xav tias kev txwv tag nrho cov yas no yog overkill? Muaj qee qhov laj thawj tseem ceeb vim li cas nws ua rau kev nkag siab. Ua ntej, yas hauv qhov chaw pov tseg tsuas yog tsis ploj mus. Raws li Weldon, lub hnab yas yuav siv sij hawm 10 mus rau 20 xyoo kom degrade, thaum lub raj mis yas siv yuav luag 500 xyoo. Thiab, txawm tias thaum nws "tawm mus," nws cov seem tseem nyob.
“Plastic yeej tsis tawg lossis ploj mus; Nws tsuas yog tawg mus rau hauv cov me me thiab me me kom txog rau thaum lawv muaj cov kab mob me me uas lawv tuaj yeem pom hauv peb cov huab cua thiab peb cov dej haus, " Kathryn Kellogg, tus sau thiab tus tsim ntawm lub vev xaib txo cov khib nyiab Going Zero Waste, hais hauv email.
Qee lub khw muag khoom noj tau hloov mus rau biodegradable hnab yas khw muag khoom raws li txoj hauv kev kom tau raws li cov neeg siv khoom hauv nruab nrab, tab sis kev tshawb fawb qhia tias qhov no tsis yog ib qho kev daws teeb meem. Ib txoj kev tshawb fawb los ntawm cov kws tshawb fawb ntawm University of Plymouth hauv tebchaws Askiv tau tshuaj xyuas 80 ib leeg-siv cov hnab ntim khoom noj khoom haus uas ua los ntawm cov yas biodegradable hauv peb lub xyoos. Lawv lub hom phiaj? Txiav txim siab li cas "biodegradable" cov hnab no tiag tiag. Lawv qhov kev tshawb pom tau luam tawm nyob rau hauv phau ntawv journal Environmental Science & Technology.
Av thiab dej hiav txwv tsis ua rau lub hnab degradation. Hloov chaw, peb ntawm plaub hom hnab biodegradable tseem muaj zog txaus los tuav txog li 5 phaus (2.2 kilograms) ntawm cov khoom noj khoom haus (raws li cov hnab uas tsis yog biodegradable). Cov raug lub hnub tau tawg - tab sis qhov ntawd tsis tas yuav zoo ib yam. Cov khoom me me los ntawm kev puas tsuaj tuaj yeem kis tau sai sai hauv ib puag ncig - xav tias huab cua, dej hiav txwv lossis lub plab ntawm cov tsiaj tshaib plab uas ua yuam kev cov khoom tawg yooj yim rau zaub mov.
Peb puas tuaj yeem rov siv dua ib zaug siv yas?
Lwm qhov laj thawj ntau lub tebchaws txwv tsis pub siv cov yas ib zaug yog vim lawv yuav tsum tsis txhob rov siv dua, txawm tias peb lub hom phiaj zoo tshaj plaws. Raws li ntau lub nroog forego recycling, nws yog kev ntxias kom coj teeb meem rau hauv koj tus kheej txhais tes los ntawm kev rov siv dua (thiab yog li "rov ua dua") lub raj mis yas thiab ntim. Tseeb, qhov no yuav ua haujlwm rau lub hnab, tab sis cov kws tshaj lij hais kom ceev faj thaum nws los txog rau lub raj mis yas lossis ntim khoom noj. Ib txoj kev tshawb fawb hauv Environmental Health Perspectives tau pom tias txhua yam khoom siv yas siv hauv cov thawv ntim khoom noj thiab lub raj mis yas tuaj yeem tso cov tshuaj phem yog siv ntau zaus. (Qhov no suav nrog cov uas tau hais tias tsis muaj bisphenol A [BPA] - cov tshuaj tsis sib haum xeeb uas tau txuas nrog kev cuam tshuam hormonal.)
Thaum cov kws tshawb fawb tseem tshuaj xyuas qhov kev nyab xeeb ntawm cov yas rov qab siv dua, cov kws tshaj lij pom zoo kom iav los yog hlau kom tsis txhob muaj cov tshuaj phem. Thiab raws li Weldon, nws yog lub sijhawm uas peb tau txais kev xav rov siv dua - yog nws cov paj rwb tsim cov hnab, stainless hlau straws lossis tag nrho ntawm xoom-khoom pov tseg.
Nws hais tias "Qhov phem tshaj plaws ntawm ib qho khoom siv ib zaug yog qhov peb txo qis ib yam dab tsi rau qhov peb xav muab pov tseg," nws hais. "Cov kab lis kev cai yooj yim tau ua rau tus cwj pwm phem no zoo li qub thiab vim li ntawd, peb tsim ntau lab tons ntawm nws txhua xyoo. Yog tias peb hloov peb lub siab xav txog yam peb haus, peb yuav paub ntau ntxiv txog cov yas siv ib zaug uas peb siv thiab peb tuaj yeem zam nws li cas. "
