Tej zaum koj twb hnov qhov kev sib cav mus rau ob txoj kev. Cov hnab ntawv zoo dua li yas. Tsis muaj - yas muaj cov pa roj carbon tsawg dua li ntawv. Reusable hnab yog tib lo lus teb tiag. Qhov tseeb, paj rwb tote hnab tej zaum yuav phem dua li yas.
Tag nrho cov lus thov no muaj qee qhov tseeb hauv lawv, uas yog vim li cas kev sib tham nyob twj ywm tsis meej pem. Cov lus teb tiag yog nyob ntawm peb yam: yuav ua li cas lub hnab ua, pes tsawg zaus koj siv, thiab yuav ua li cas rau nws tom qab. Phau ntawv qhia no ua haujlwm los ntawm tag nrho peb - kev kos duab ntawm kev tshawb fawb txog kev ua neej nyob - yog li koj tuaj yeem txiav txim siab paub tseeb thaum lwm zaus koj sawv ntawm qhov nyiaj tawm.
Txoj hauv kev zoo los sib piv cov hnab: Kev xav txog lub neej
Feem ntau lub hnab sib cav zero nyob rau hauv ib qho tseem ceeb - lub sij hawm decomposition, raw khoom, los yog recyclability - thiab tshaj tawm ib tug yeej. Txoj kev ntawd nqaim dhau lawm. Cov txheej txheem ib puag ncig cov kws tshawb fawb siv tau yog hu ua aKev ntsuas lub neej (LCA): tus txheej txheem txheej txheem uas taug qab cov khoom lag luam ib puag ncig los ntawm cov khoom siv raw los ntawm kev tsim khoom, siv, thiab pov tseg zaum kawg.
Thaum koj saib lub hnab los ntawm lub lens, daim duab yuav nyuaj dua - thiab ncaj ncees dua. Lub Tsev Haujlwm Saib Xyuas Ib Cheeb Tsam UK tau tshaj tawm LCA loj ntawm lub khw muag khoom nqa lub hnab hauv2011, thiab Lub Chaw Haujlwm Saib Xyuas Kev Tiv Thaiv Ib puag ncig Danish tau tshaj tawm cov lus qhia ua raws -txoj kev kawm hauv2018npog 16 qhov ntsuas ib puag ncig thoob plaws xya lub hnab khoom. Ob qhov kev tshawb fawb tuaj txog ntawm tib qhov tsis xis nyob qhov xaus: tsis muaj lub hnab yeej thoob plaws txhua pawg. Lo lus nug yog ib txwm ua lag luam twg -offs tseem ceeb tshaj rau koj - thiab ntau npaum li cas koj tau rov qab siv lub hnab. Rau kev sib piv dav dav ntawm cov khoom sib txawv ntawm lub hnab ntim li cas, saib cov ntsiab lus ntawm nocov khoom siv lub hnab twg yog qhov ruaj khov tshaj plaws.
Peb theem txiav txim siab feem ntau ntawm lub hnab ntim ib puag ncig hneev taw:
- Ntau lawm- raw khoom, dej, zog, thiab emissions thaum lub sij hawm tsim khoom
- Siv theem- pes tsawg zaus lub hnab siv tiag tiag ua ntej muab pov tseg
- Thaum kawg ntawm lub neej- seb nws puas tau muab pov tseg, muab tso rau hauv khib nyiab, rov ua dua, lossis pov tseg
Kev siv theem yog qhov sib txawv ntawm cov neeg feem coob saib. Ib lub hnab nrog tus nqi ntau lawm tuaj yeem yog qhov kev xaiv ib puag ncig yog tias koj siv nws ntev txaus. Thiab lub hnab "biodegradable" uas xaus rau hauv qhov chaw pov tseg yam tsis muaj oxygen yuav tsis degrade muaj txiaj ntsig txhua.
Cov hnab yas thiab ib puag ncig
Cov hnab yas tau dhau los ua luv luv rau ib puag ncig kev tsis saib xyuas - thiab yog vim li cas. Tab sis daim duab tag nrho suav nrog qee cov ntaub ntawv counterintuitive tsim nyog nkag siab ua ntej tso lawv tag nrho.
Tus nqi qis tshaj plaws uas ua rau muaj teeb meem ntev -
Ib leeg-siv hnab yas yog tsim los ntawm polyethylene, muab los ntawm roj av los yog natural gas. Nyob rau hauv ib lub hnab -, lawv cov khoom yuav tsum muaj zog thiab dej me me piv rau daim ntawv lossis paj rwb. Tias yog vim li cas lawv thiaj li tseem ceeb: lawv pheej yig los ua, lub teeb yuag rau nkoj, thiab ua haujlwm zoo rau cov neeg siv khoom. Qhov teeb meem ib puag ncig tsis yog ntawm lub rooj vag Hoobkas - nws yog txhua yam uas tshwm sim tom qab.
Cov hnab yas tsis biodegrade. Lawv photodegrade, tawg mus rau hauv me me fragments ntau xyoo mus rau centuries. Tsis zoo li cov ntaub ntawv organic, yas yeej tsis rov qab los rau qhov xwm txheej. Hloov chaw, nws dhau los ua lwm yam.
Cov teeb meem Microplastics
Raws li cov hnab yas sib cais, lawv tsimmicroplastics- cov khoom me dua 5 millimeters uas kis mus rau hauv av, txoj hauv dej, thiab cov khoom noj. Ib txoj kev tshawb fawb 2022 luam tawm hauvEnvironmental Internationallos ntawm Leslie et al. yog thawj zaug tshawb nrhiav thiab txheeb xyuas cov pa phem hauv cov ntshav hauv tib neeg cov ntshav, nrhiav cov microplastics hauv 17 ntawm 22 tus neeg laus noj qab haus huv kuaj. Polyethylene - cov khoom siv los ua cov hnab yas nqa khoom - yog cov khoom kuaj pom. A2024 review inNtuj TshuajCov ntaub ntawv pov thawj tshwm sim txuas nrog microplastic txuam nrog tib neeg cov ntaub so ntswg nrog cov kab mob plawv thiab lwm yam kev txhawj xeeb txog kev noj qab haus huv, thaum pom tias kev tshawb fawb tseem nyob rau theem pib.
Nyob rau hauv ib puag ncig marine, cov hnab yas ntim cov vaub kib, seabirds, thiab marine mammals, los yog noj tom qab ua yuam kev rau jellyfish. Ib lub hnab uas ncav cuag dej hiav txwv tuaj yeem ua rau muaj kev puas tsuaj rau ntau pua xyoo.
Qhov Sib Nqus Recycling
Cov hnab yas yog technically recyclable, tab sis nyob rau hauv kev xyaum lawv tsis tshua muaj. Feem ntau curbside cov kev pab cuam tsis lees txais lawv vim lawv jam sorting machinery. Raws li covUS Environmental Protection Agency, tus nqi rov ua dua tshiab rau cov hnab yas, cov hnab ntim khoom, thiab cov ntaub qhwv yog nyob ib ncig ntawm 10% hauv 2018. Cov kev kwv yees tsis ntev los no qhia tias tag nrho cov yas rov ua dua tshiab tau poob qis dua. Qhov kev muaj tiag yog tias feem ntau ib leeg - siv hnab yas xaus rau hauv qhov chaw pov tseg, hlawv, lossis ib puag ncig.
Puas Muaj Ib Qhov Case rau Yas?
Zoo, yog - nrog caveats. Yog tias lub hnab yas rov qab siv tsawg kawg yog plaub zaug ua ntej muab pov tseg (piv txwv li, ib zaug ua lub hnab yuav khoom thiab tom qab ntawd ua lub hnab ntim khoom), UK Environment Agency's LCA pom nws lub ntiaj teb ua kom sov tuaj yeem poob mus rau theem piv nrog lwm hom hnab. Hauv cov cheeb tsam uas tsis muaj composting infrastructure, qhov kawg - ntawm - lub neej zoo ntawm cov ntawv los yog compostable hnab nqaim heev. Qhov teeb meem tsis tshua muaj nrog cov khoom siv hauv kev xav. Nws yog nrog ib zaug - siv pov tseg hauv kev xyaum.
Daim Ntawv Hnab thiab Ib puag ncig
Cov hnab ntawv xav tias instinctively ntsuab. Lawv tuaj ntawm cov ntoo, lawv decompose, thiab lawv tuaj yeem rov ua dua. Tab sis lawv cov kev tsim tawm hneev taw hnyav dua li cov neeg feem coob paub.
Tus nqi tsim khoom siab dua, Zoo kawg ntawm lub neej
Cov hnab ntawv yog tsim los ntawm cov ntoo pulp, cov khoom siv txuas ntxiv dua tshiab - muab cov hav zoov raug tswj xyuas lub luag haujlwm. Kev tsim ib qho, txawm li cas los xij, yuav tsum muaj zog thiab dej ntau dua li ua ib lub hnab yas sib npaug. Daim ntawv hnyav dua, uas kuj nce kev thauj mus los ntawm ib chav tsev. Lub Tsev Haujlwm Saib Xyuas Kev Ruaj Ntseg Hauv Tebchaws UK LCA pom tias lub hnab ntawv yuav tsum tau rov qab siv tsawg kawg peb zaug kom haum rau lub ntiaj teb ua kom sov lub peev xwm ntawm ib zaug xwb - siv hnab yas. Siv ib zaug thiab xa mus rau qhov chaw pov tseg, ib lub hnab ntawv ua tau zoo dua li lub hnab yas ntawm ntau pawg.
Ntev npaum li cas cov hnab ntawv coj mus decompose?
Qhov twg cov hnab ntawv tiag tiag outperform yas yog thaum kawg ntawm lub neej:
- Nyob rau hauv active composting: 2 mus rau 6 lub lis piam
- Hauv qhov chaw pov tseg: 1 mus rau 3 lub hlis (tsis muaj oxygen thiab noo noo)
- Cov hnab yas hauv qhov chaw pov tseg: 20 mus rau 500 xyoo, fragmenting rau hauv microplastics thoob plaws
Qhov txawv ntawd tseem ceeb. Ib lub hnab ntawv tawg hauv qhov chaw pov tseg hauv lub hlis, thiab tso tawm tsis muaj qhov tsis tu ncua, yog qhov muaj txiaj ntsig tsawg dua li lub hnab yas uas tawg rau hauv microplastics ntau xyoo lawm.
Saib rau cov yas zais
Ntau lub hnab ntawv muaj xws li cov hnab yas, cov laminated coatings, los yog cov ntaub ntawv siv quav ciab - tag nrho cov uas tiv thaiv lub hnab los ntawm composted los yog siv dua. Ua ntej composting los yog muab tso rau hauv daim ntawv recycling, tshem tawm tej yam tsis yog -paper Cheebtsam. Ib lub hnab ntawv tsis muaj coated uas tsis muaj cov khoom siv yas yog compostable nyob rau hauv ob qho tib si hauv tsev thiab hauv nroog, thiab tau txais nyob rau hauv feem ntau curbside paper recycling programs.
Reusable Bags thiab Ib puag ncig
Lub hnab rov qab siv tau yog qhov ntev ntev - xaiv lub sijhawm rau cov neeg feem coob - tab sis tsuas yog siv tau tiag tiag. Daim ntawv lo "eco" ntawm lub hnab tsis ua haujlwm ib puag ncig. Tus naj npawb ntawm kev siv ua.
Tus nqi tsim khoom feem ntau mus tsis tau hais txog
Ib lub hnab paj rwb muaj ntau dua ib puag ncig hneev taw ntawm theem tsim khoom dua li lub hnab yas lossis ntawv. Paj rwb yog ib qho ntawm cov dej ntau tshaj - cov qoob loo loj hlob ntawm cov nplai thiab muaj keeb kwm cia siab rau kev siv tshuaj tua kab tseem ceeb. Ua cov paj rwb nyoos rau hauv cov ntaub tiav yuav tsum muaj lub zog loj.
Qhov no yog vim li cas ob lub UK Environment Agency thiab Danish EPA tau xaus lus tias cov hnab paj rwb yuav tsum tau siv ntau zaus ntau dua li cov neeg siv khoom feem ntau xav tau ua ntej lawv lub neej cuam tshuam los ua kev sib tw nrog ib leeg -siv yas - tshwj xeeb tshaj yog thaum qhov kev sib piv tau ua thoob plaws txhua qhov ntsuas ib puag ncig, tsis yog cov pa roj carbon hneev taw xwb. Yog xav paub ntxiv txog seb qhov kev sib piv no ua li cas,qhov kev tsom xam ntawm cov hnab paj rwb vs cov hnab yas hla kev siv qhov pibyog tsim nyog nyeem.
Muaj pes tsawg zaus koj yuav tsum siv lub hnab rov siv tau?
Qhov no yog cov lus nug feem ntau lub hnab sib piv tsis tau teb. Raws li covDanish EPA txoj kev kawm 2018 LCAthiab UK Environment Agency's 2011 LCA, ntawm no yog qhov tsawg kawg nkaus rov siv dua qhov yuav tsum tau ua kom phim lossis tuav lub ntiaj teb sov lub peev xwm ntawm ib zaug xwb -siv hnab yas:
| Hnab Khoom | Min. Siv kom tawg sib npaug (GWP / Carbon Footprint) | Ntsiab Lus Caveat |
|---|---|---|
| Lub hnab ntawv | 3-4 zaug | Yuav tsum tau siv dua los yog composted, tsis yog landfilled |
| Tsis yog -woven polypropylene (PP) | ~ 11 x | Recyclability txawv raws qhov chaw |
| Paj rwb canvas | ~ 131 zaug (UK EPA) / ~ 50–1,400 zaug thoob plaws txhua qhov ntsuas (Danish EPA) | Ntau yam qhia txog cov kev cuam tshuam sib txawv uas ntsuas |
| Organic paj rwb | ~ 7,100–20,000 zaug (Danish EPA, thoob plaws txhua qhov ntsuas) | Lub sab saum toj kawg nkaus yog tsav los ntawm ozone depletion cuam tshuam; GWP-tsuas yog daim duab qis dua |
Cov organic paj rwb xov tooj xav tau cov ntsiab lus teb. Lub Danish EPA's 20,000-siv daim duab qhia txog qhov phem tshaj plaws - cov ntaub ntawv qhia - ozone depletion - tsis carbon footprint ib leeg. Thaum ntsuas tsuas yog ntawm lub ntiaj teb ua kom sov muaj peev xwm, qhov pib ntawm cov paj rwb organic yog qhov qis dua, thiab thaum kawg qhov tseeb - txoj hauv kev ntawm lub neej xws li composting suav nrog, cov hnab paj rwb ua tau zoo dua. Tab sis qhov ntau yam qhia txog qhov tseeb: yog tias koj tab tom yuav cov paj rwb organic vim tias nws zoo li kev coj ncaj ncees, koj yuav tsum tau cog lus tias yuav siv nws rau ntau xyoo los ua pov thawj cov hneev taw ntau lawm.
Lub tswv yim upshot:non-cov hnab polypropylene wovenmus txog lawv qhov kev so- txawm tias qhov pib tom qab tsawg dua ob lub lis piam ntawm kev yuav khoom noj tsis tu ncua. IbrPET lossis tsis yog - lub hnab woven siv tas lirau ib xyoos yog kom meej meej ua ntej ntawm ib qho kev xaiv pov tseg ntawm feem ntau metrics. Cov paj rwb canvas tote siv ob zaug hauv ib lub lis piam rau ob xyoos yooj yim tshaj nws qhov pib - yog tias koj siv tiag tiag.
Dab tsi txawv Reusable Bag Materials Tiag tiag
Tsis yog txhua lub hnab rov siv tau zoo sib npaug, thiab cov khoom siv xaiv tseem ceeb:
Tsis yog -woven polypropylene (PP)yog cov khoom siv rov siv dua qub tshaj plaws - lub teeb yuag, pheej yig, thiab qis - carbon los tsim. Nws ncav cuag nws qhov kev so-txawm qhov taw tes sai, ua rau nws siv tau rau cov neeg yuav khoom nquag. Nws tsis yog biodegradable, tab sis nws kav rau xyoo nrog kev siv ib txwm. Yog xav paub ntxiv txog yuav ua li caswoven thiab non{0}}woven hnab PP piv, nrog rau cov kav ntev thiab cov kev xaiv luam tawm, cov khoom sib txawv tsim nyog nkag siab ua ntej koj xaj.
Recycled PET (rPET)yog tsim los ntawm kev tshaj tawm- cov neeg siv khoom siv lub raj mis yas, txhais tau tias nws hloov pauv cov pov tseg yas uas twb muaj lawm es tsis xav tau cov roj av tshiab. Nws cov hneev taw ntau lawm yog qis dua nkauj xwb PP, thiab nws muaj qhov zoo sib xws thiab qhov sib piv sib piv -txawm qhov pib.100% rPET hnab khoomyog ib qho ntawm cov kev xaiv zoo ib puag ncig tam sim no, thiab ntau lub npe tam sim no siv lawv rau kev tshaj tawm thiab cov hnab muag khoom. Yog koj xav nkag siabdab tsi rPET yog dab tsi thiab nws tau tsim li cas, cov txheej txheem yog qhov nthuav hauv nws tus kheej - nws yog ib qho ntawm ob peb kis uas xaiv cov yas-raws li cov khoom lag luam txo cov pov tseg yas.
Paj rwb thiab canvasyog ruaj, ntxuav, biodegradable, thiab tsim tsis muaj microplastics. Kev tsim cov hneev taw siab txhais tau hais tias ntev ntev - siv sijhawm yog qhov tseem ceeb. Ntxuav tsuas yog thaum tsim nyog thiab qis dua - tshaj - ntxhua khaub ncaws nce cov nqi carbon ntau thiab ua rau lub hnab luv.Paj rwb khw hnabua hauj lwm zoo tshaj plaws thaum kho raws li kev nqis peev ntev - tsis yog ib qho khoom siv pov tseg.
Jute thiab hempyog ib txwm biodegradable, loj hlob nrog tsawg kawg nkaus dej thiab tshuaj tua kab inputs, thiab compost kom huv si thaum kawg ntawm lub neej. Lawv zoo - haum rau cov khoom hnyav thiab muaj cov hneev taw qis dua li paj rwb. Tsawg dua li paj rwb lossis PP, tab sis qhov kev xaiv muaj zog yog qhov muaj.
Rau cov hom lag luam thiab cov lag luam, kev xaiv ntawm cov khoom siv lub hnab nqa lub koob npe nrov thiab cov khoom lag luam cuam tshuam dhau ntawm kev siv tus kheej -txawm tias tsis yog -cov hnab woven tiag tiag eco- phooj ywgnyob ntawm seb muaj pes tsawg tus neeg siv khoom, tus nqi siv, thiab pov tseg, raws li qhov kev sib cais no piav qhia. Ib yam li ntawd,ib puag ncig daim ntawv pov thawj rau kev cai tote hnabtuaj yeem pab txheeb xyuas cov neeg siv khoom thov.
Thaum Reusable Advantage Disappears
Reusable hnab poob lawv ib puag ncig ntug thaum:
- Lawv tau siv ntau zaus ua ntej tsis nco qab lossis muab pov tseg
- Koj khaws cov khoom tshiab los ntawm kev tshaj tawm cov khoom plig yam tsis tau siv cov uas koj twb muaj lawm
- Cov hnab paj rwb yog tshuab- ntxuav tom qab siv txhua zaus
- Lawv tau tsim los ntawm cov khoom siv hluavtaws uas tsis muaj qhov kawg nkaus - ntawm - txoj kev npaj lub neej
Lub hnab rov siv tau zoo tshaj plaws yog qhov koj twb muaj thiab siv tas li. Qhov ntawd tsis yog platitude - nws yog qhov cuam tshuam ncaj qha ntawm cov ntaub ntawv lub neej.

Lub hnab twg koj yuav tsum siv tiag?
Cov lus teb nyob ntawm seb koj nyob qhov twg hauv qhov kev txiav txim siab thiab koj yuav ua li cas nrog lub hnab.
Yog tias Koj Twb Muaj Cov Hnab Rov Siv Tau
Siv lawv. Qhov ntawd yog nws. Kev nqis peev ib puag ncig ntawm kev tsim cov hnab no tsuas yog them los ntawm kev siv tiag tiag. Tsis txhob hloov lawv mus txog thaum lawv tau hnav tiag tiag. Kho lawv thaum ua tau - ob peb stitches txuas lub hnab lub neej ntau heev. Ntxuav hnab paj rwb tsuas yog thaum tsim nyog thiab ntawm 30-40 degree.
Yog tias koj xaiv ntawm Kev Tshawb Fawb Ntawm Cov Ntawv thiab Yas
Xav txog dab tsi tshwm sim rau lub hnab tom qab koj mus txog tsev:
- Xaivntawvyog tias koj muaj kev nkag mus rau composting los yog ntawv rov ua dua, thiab koj tsis nqa dab tsi ntub
- Xaivyasyog tias koj yuav rov siv dua tsawg kawg yog ob lossis peb zaug ntxiv - ua ib lub hnab ntim khoom, piv txwv li - ua ntej muab pov tseg
- Yog tias ob qho kev xaiv mus ncaj nraim mus rau qhov chaw pov tseg uas tsis siv, daim ntawv tseem yog qhov teeb meem tsawg dua: nws degrades hauv lub hlis es tsis yog ntau pua xyoo, thiab tsis tso cov microplastics.
Yog tias koj tab tom yuav ib lub hnab Reusable
Rau kev muag khoom txhua hnub,tsis yog -woven PP lossis rPEThnab yog qhov kev xaiv zoo tshaj plaws - cov hneev taw qis qis, tawg-txawm tias nyob rau hauv ob lub lis piam ntawm kev siv, thiab muaj nyob rau hauv siab - cov kev xaiv zoo rau kev muag khoom thiab kev txhawb nqa. Rau ib lub hnab txhua hnub koj yuav nqa tau ntau xyoo,paj rwb los yog juteua kom paub ntau ntxiv thaum qhov kev cog lus siv nyob rau hauv qhov chaw.
Ib lub hnab hnav, zoo- siv lub hnab canvas uas koj muaj rau peb xyoos yuav ua tau zoo dua ib lub hom phiaj - lub hnab tshiab nrog daim ntawv lo kom ruaj khov. Raws li ntau tus neeg yuav khoom txav deb ntawm ib leeg - siv cov yas rau qhov laj thawj zoo, qhovhloov mus rau cov hnab uas siv tauyog nrawm dua - tab sis qhov txiaj ntsig ib puag ncig nyob ntawm seb cov hnab no puas tau siv. Ntau qhov dav,kev sib piv ncaj qha ntawm ib zaug - siv hnab yas piv rau cov polyester uas siv tau duaua rau lub sij hawm ntev - ib puag ncig kev ua lej kom meej.
Tsib Myths Tsim Nyog Kho
Tswvyim 1: "Lub hnab ntawv yeej ib txwm zoo dua li yas."
Ntawm decomposition thiab microplastics, ntawv yeej. Ntawm cov pa roj carbon hneev taw ntawm theem tsim khoom, cov hnab yas qis dua ib chav. Daim ntawv yog qhov kev xaiv zoo tshaj plaws ntawm qhov kev txiav tawm, tab sis tsuas yog yog cov khib nyiab lossis rov ua dua - tsis yog pov tseg.
Tswvyim 2: "Lub hnab rov siv tau yog qhov kev xaiv ntsuab dua."
Tsuas yog thaum siv sijhawm txaus. Ib lub hnab paj rwb siv tsib zaug thiab muab pov tseg muaj ib puag ncig zoo dua li tsib zaug - siv hnab yas. Daim ntawv lo tsis ua haujlwm ib puag ncig - siv tsis tu ncua.
Tswvyim 3: "Biodegradable hnab yas daws qhov teeb meem."
Ntau yam li-hu ua biodegradable hnab yas yog oxo-degradable: lawv tawg mus rau hauv microplastics es tsis ua rau tag nrho cov organic teeb meem. Qhov no tsis yog biodegradation tiag tiag. Lub hnab compostable tiag tiag muaj nyob, tab sis feem ntau xav tau cov chaw tsim khoom siv, uas feem ntau cov neeg siv khoom tsis tuaj yeem nkag tau yooj yim.
Tswvyim 4: "Recycling yuav saib xyuas cov hnab yas."
Cov hnab yas yog technically recyclable tab sis raug tsis lees paub los ntawm feem ntau curbside cov kev pab cuam vim lawv clog sorting khoom. Hauv Teb Chaws Asmeskas, tsuas yog li 10% ntawm cov hnab yas thiab cov ntaub qhwv rov siv dua. Feem ntau xaus rau hauv qhov chaw pov tseg lossis ib puag ncig, tsis hais txog kev rov ua dua tshiab.
Tswvyim 5: "Organic paj rwb yog cov khoom siv ruaj khov tshaj plaws."
Organic paj rwb zam cov tshuaj tua kab hluavtaws thiab tuaj yeem txhim kho av kev noj qab haus huv - qhov zoo tiag tiag. Tab sis nws tseem muaj dej- hnyav, thiab Danish EPA cov kev tshawb fawb qhia tau hais tias nws qhov kev cuam tshuam ntau lawm yuav tsum tau siv ntau heev ua ntej tus lej ib puag ncig nyiam nws dua li yas, tshwj xeeb tshaj yog thaum tag nrho 16 qhov ntsuas ib puag ncig raug txiav txim siab. Nws yog qhov kev xaiv zoo rau ib tus neeg cog lus ntev - siv txhua hnub, tsis yog kev xaiv ntsuab ntsuab.
Cov lus nug nquag
Cov hnab ntawv puas zoo dua li hnab yas?
Hauv feem ntau tiag tiag - lub ntiaj teb no, yog. Cov hnab ntawv decompose nyob rau hauv lub lis piam mus rau lub hlis, tuaj yeem composted los yog recycled, thiab tsis muaj microplastics. Lawv qhov tsis zoo yog qhov siab dua rau -bag carbon footprint thaum tsim khoom dua li yas. Qhov kom zoo dua yog thaum lub hnab ntawv tau muab tso rau hauv lub hnab kom zoo lossis rov ua dua tom qab siv - tsis yog thaum lawv mus rau qhov chaw pov tseg.
Muaj pes tsawg zaus kuv yuav tsum tau siv lub hnab rov siv dua kom nws ua tau zoo dua?
Rau cov uas tsis yog -cov hnab polypropylene lossis rPET, nyob ib ncig ntawm 11 zaug raws li UK Environment Agency's LCA - uas tsawg dua peb lub hlis ntawm kev yuav khoom noj txhua lub lim tiam. Rau ib lub hnab ntim paj rwb, ib ncig ntawm 131 zaug raws li tib txoj kev kawm. Siv nws tsis tu ncua rau ib xyoos thiab koj zoo dhau qhov pib. Cov organic paj rwb daim duab yog siab dua thiab nyob ntawm qhov hnyav ntawm qhov ntsuas ib puag ncig koj ntsuas.
Puas yog cov hnab rov siv tau tsis zoo rau ib puag ncig?
Tsis yog thaum siv tas li. Qhov kev txhawj xeeb yog tias cov hnab uas muaj cov hneev taw ntau lawm - tshwj xeeb yog paj rwb - yuav tsum tau siv ntau yam ua ntej lawv ib - siv ib puag ncig cuam tshuam qhov sib tw ntawm ib qho - siv cov yas. Yog tias ib lub hnab tsis tshua siv, nws tsis pom zoo rau nws cov nqi tsim khoom. Txoj kev daws teeb meem yog ncaj nraim: siv yam koj muaj, kho nws thaum xav tau, thiab tsis txhob khaws cov khoom tshiab.
Microplastics yog dab tsi thiab vim li cas lawv tseem ceeb?
Microplastics yog cov khoom yas hauv qab 5 millimeters uas ua rau cov khoom yas loj dua photodegrade. Lawv kis tau los ntawm av, dej tshiab, thiab dej hiav txwv ecosystems, yog siv los ntawm cov kab mob hauv hiav txwv, thiab txav mus rau cov khoom noj. Ib txoj kev tshawb fawb 2022 luam tawm hauvEnvironmental Internationalyog thawj zaug kuaj pom microplastics hauv tib neeg cov ntshav.
