Hauv kev sib zog los txiav cov khoom pov tseg yas, ntim khoom yog siv ntau hom ntawv uas tuaj yeem siv tau yooj yim dua lossis ua rau cov yas tag nrho.
Cov rings yas ubiquitous nrog rau-packs ntawm npias thiab dej qab zib yog maj mam dhau los ua ib yam ntawm yav dhau los raws li ntau tuam txhab uas muag hloov mus rau greener ntim.

Cov kev hloov pauv tau txais ntau hom ntawv - los ntawm cov duab los qhia rau 6-pob rings ua nrog cov khoom noj barley straw. Thaum cov kev hloov pauv tuaj yeem ua ib kauj ruam mus rau kev ruaj khov, qee cov kws tshaj lij hais tias tsuas yog hloov mus rau cov khoom ntim sib txawv tuaj yeem yog cov tshuaj tsis raug lossis tsis txaus, thiab cov yas ntau dua yuav tsum tau siv dua thiab rov ua dua.

Lub hli no, Coors Light tau hais tias nws yuav tsum tsis txhob siv lub nplhaib rau lub pob yas ntim rau hauv lub ntim ntawm nws cov npe North American, hloov lawv nrog cov ntaub qhwv cov ntaub ntawv los ntawm qhov kawg ntawm 2025 thiab tshem tawm 1.7 lab phaus ntawm cov khib nyiab yas txhua xyoo.

Qhov pib, uas lub tuam txhab tau hais tias yuav tau txais kev txhawb nqa los ntawm $ 85 lab kev nqis peev, yog qhov tseeb los ntawm lub hom phiaj tseem ceeb los hloov lub voj voog rau lub nplhaib uas tau dhau los ua lub cim ntawm kev puas tsuaj rau ib puag ncig.
Txij li xyoo 1980s, cov kws tshawb fawb ib puag ncig tau ceeb toom tias cov yas pov tseg tau tsim hauv cov chaw pov tseg, cov kav dej thiab cov dej ntws, thiab ntws mus rau hauv dej hiav txwv. Ib txoj kev tshawb fawb xyoo 2017 pom tias cov yas ua paug rau txhua qhov dej hiav txwv loj, thiab kwv yees li plaub lab txog 12 lab metric tons ntawm cov yas pov tseg nkag mus rau hauv dej hiav txwv hauv xyoo 2010 ib leeg.

Cov nplhaib yas tau paub tias cuam tshuam cov tsiaj hiav txwv, qee zaum nyob twj ywm rau ntawm lawv thaum lawv loj hlob, thiab feem ntau noj los ntawm cov tsiaj. Thaum txiav cov nplhaib yas los ua ib txoj hauv kev nrov los tiv thaiv cov tsiaj los ntawm kev nkag mus, nws kuj tau teeb meem rau cov tuam txhab sim rov ua dua tshiab, Patrick Krieger, tus lwm thawj coj ntawm kev ruaj khov rau Plastics Industry Association, tau hais.
"Thaum koj tseem yog menyuam yaus, lawv tau qhia koj ua ntej koj pov tseg lub nplhaib rau lub pob uas koj yuav tsum tau txiav rau hauv me me kom yog tias muaj qee yam txaus ntshai uas nws tsis tau ntes tau os lossis vaub kib hauv nws," Mr. Krieger hais tias.

"Tab sis nws ua tau ua rau nws me me uas nws nyuaj heev los txheeb xyuas," nws hais.

Yawg Krieger tau hais tias cov tuam txhab muaj ntau xyoo nyiam cov hnab yas-voj ntim vim nws pheej yig thiab hnav.

Nws tau hais tias "Nws khaws tag nrho cov kaus poom txhuas ua ke hauv txoj kev zoo nkauj, zoo huv si thiab huv si," nws hais. "Tam sim no peb nkag siab tias peb tuaj yeem ua tau zoo dua li kev lag luam thiab cov neeg siv khoom xav siv ntau hom khoom."
Cov khoom siv tau raug tawm tsam los ntawm cov neeg tawm tsam rau qhov kev puas tsuaj uas tuaj yeem ua rau tsiaj qus thiab kev txhawj xeeb txog kev ua qias tuaj. Xyoo 1994, Tsoomfwv Meskas tau yuam kom cov yas rau lub nplhaib yuav tsum degradable. Tab sis yas txuas ntxiv loj hlob raws li ib puag ncig teeb meem. Nrog ntau tshaj li yim billion metric tons ntawm cov yas tsim txij li xyoo 1950, 79 feem pua ​​​​tau muab tso rau hauv qhov chaw pov tseg, raws li kev tshawb fawb 2017.

Hauv nws daim ntawv tshaj tawm, Coors Light tau hais tias nws yuav piv rau kev siv cov khoom siv uas yog 100 feem pua ​​​​uas ruaj khov, txhais tau tias nws tsis muaj yas, rov ua dua tshiab thiab rov siv dua.

"Lub ntiaj teb xav tau peb kev pab," lub tuam txhab tau hais hauv nqe lus. “Kev siv cov yas ib leeg ua rau ib puag ncig tsis zoo. Cov peev txheej dej muaj tsawg, thiab qhov kub thiab txias thoob ntiaj teb tau nce nrawm dua li qhov qub. Peb txias txog ntau yam, tab sis qhov no tsis yog ib qho ntawm lawv. "

Lwm lub npe tseem tab tom hloov pauv. Xyoo tas los, Corona tau tshaj tawm cov ntim khoom ua los ntawm cov khoom seem barley straw thiab siv cov ntoo fibers. Thaum Lub Ib Hlis, Grupo Modelo tshaj tawm txog $ 4 lab peev los hloov cov ntim yas uas nyuaj rau rov siv dua nrog cov ntaub ntawv fiber ntau, raws li AB InBev, uas saib xyuas ob lub npe npias.

Coca-Cola tau tsim 900 tus qauv lub raj mis ua yuav luag tag nrho cov khoom siv yas, tsis suav nrog lub hau thiab daim ntawv lo, thiab PepsiCo tau cog lus tias yuav ua Pepsi fwj nrog 100 feem pua ​​​​cov yas rov ua dua tshiab hauv cuaj lub khw European thaum kawg ntawm lub xyoo.

Los ntawm kev pib hauv kev lag luam xaiv, cov tuam txhab tuaj yeem "ua ib txoj hauv kev hauv zos los txheeb xyuas cov kev daws teeb meem uas tuaj yeem hloov tau," Ezgi Barcenas, tus thawj coj saib xyuas kev ruaj ntseg ntawm AB InBev, tau hais.

Tab sis "qee qhov kev xav tsis zoo" yog nyob rau hauv kev txiav txim, Roland Geyer, tus xibfwb ntawm kev lag luam ecology ntawm University of California, Santa Barbara, tau hais.
"Kuv xav tias muaj qhov sib txawv loj ntawm cov tuam txhab tsuas yog tswj hwm lawv lub koob npe nrov thiab xav kom pom ua ib yam dab tsi, thiab cov tuam txhab ua ib yam dab tsi uas muaj txiaj ntsig tiag tiag," xibfwb Geyer tau hais. "Qee zaum nws nyuaj heev los qhia ob leeg sib nrug."

Elizabeth Sturcken, tus thawj tswj hwm ntawm Environmental Defense Fund, tau hais tias Coors Light cov lus tshaj tawm thiab lwm tus hais txog kev siv cov yas ntau dhau yog "cov kauj ruam loj ntawm txoj kev raug," tab sis cov tuam txhab yuav tsum hloov lawv cov qauv kev lag luam los daws lwm yam teeb meem ib puag ncig xws li tso pa tawm.

Ms. Sturcken tau hais tias "Thaum nws los daws qhov teebmeem huab cua, qhov tseeb nyuaj yog qhov kev hloov pauv zoo li no tsis txaus," Ms. Sturcken tau hais. "Tackling lub micro yam tsis tau hais txog macro yog qhov tsis tau txais."

Alexis Jackson, txoj cai tswjfwm dej hiav txwv thiab cov yas ua rau Nature Conservancy, tau hais tias "txoj cai tswjfwm zoo tshaj plaws" yog xav tau los tsim kom muaj lub neej ntev dua.

Nws tau hais tias "Kev ua siab dawb thiab kev cog lus tsis tu ncua tsis txaus los txav lub koob ntawm qhov uas yuav yog ib qho kev sib tw loj tshaj plaws ntawm peb lub sijhawm," nws hais.

Thaum nws los txog rau cov yas, qee cov kws tshaj lij hais tias tsuas yog hloov mus rau cov khoom ntim sib txawv yuav tsis tso tseg cov khib nyiab los ntawm cov dej ntws.
"Yog tias koj hloov los ntawm lub nplhaib yas mus rau lub nplhaib ntawv, lossis rau lwm yam, tej zaum yuav tseem muaj txoj hauv kev zoo los xaus rau hauv ib puag ncig lossis raug hlawv," Joshua Baca, tus lwm thawj coj ntawm kev faib khoom yas ntawm Asmeskas Chemistry Council, hais.

Nws hais tias cov tuam txhab raug yuam kom hloov lawv cov qauv kev lag luam. Qee qhov nce ntxiv ntawm cov khoom siv rov ua dua tshiab siv hauv ntim.

Coca-Cola npaj yuav ua kom nws cov ntim rov ua dua tshiab thoob ntiaj teb los ntawm 2025, raws li nws Daim Ntawv Qhia Kev Lag Luam & Ib puag ncig, Social thiab Kev Tswj Xyuas, luam tawm xyoo tas los. PepsiCo tseem npaj tsim cov khoom ntim rov ua dua tshiab, compostable lossis biodegradable los ntawm 2025, nws daim ntawv qhia txog kev ua tau zoo.

Qee cov khoom siv tes ua breweries - zoo li Deep Ellum Brewing Company hauv Texas thiab Greenpoint Beer & Ale Co. hauv New York - siv cov yas tuav ruaj khov, uas tuaj yeem yooj yim dua rov siv dua txawm tias lawv yog cov yas ntau dua li cov nplhaib.

Mr. Baca tau hais tias tuaj yeem muaj txiaj ntsig yog tias nws yooj yim dua rau cov yas rov ua dua dua li muab pov tseg.

Krieger tau hais tias kev hloov pauv mus rau cov ntawv ntim khoom kom ruaj khov dua kom muaj qhov sib txawv, kev sau thiab txheeb xyuas yuav tsum yooj yim dua, cov khoom siv rov ua dua tshiab, thiab tsawg dua cov yas tshiab yuav tsum tau tsim, Mr. Krieger tau hais.

Raws li kev thuam los ntawm cov pab pawg tawm tsam cov yas, nws tau hais tias: "Peb yuav tsis tuaj yeem rov ua dua peb txoj kev tawm ntawm qhov teeb meem ntawm kev siv ntau dhau."
