Raws li kev txheeb cais los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv Ib Cheeb Tsam ntawm Hong Kong SAR Tsoom Fwv hauv 2022, 227 tons ntawm yas thiab styrofoam tableware raug muab pov tseg hauv Hong Kong txhua hnub, uas yog ntau tshaj 82,000 tons txhua xyoo. Txhawm rau daws qhov teeb meem ib puag ncig los ntawm cov khoom siv yas pov tseg, SAR tsoomfwv tau tshaj tawm tias cov cai lij choj cuam tshuam txog kev tswj hwm cov khoom siv yas pov tseg thiab lwm yam khoom yas yuav raug siv txij lub Plaub Hlis 22, 2024, kos npe pib ntawm tshooj tshiab hauv Hong. Kong txoj kev tiv thaiv ib puag ncig. Txawm li cas los xij, txoj hauv kev mus rau lwm txoj kev ruaj ntseg tsis yooj yim, thiab cov khoom siv biodegradable, thaum cog lus, ntsib cov teeb meem nyuaj. Hauv cov ntsiab lus no, peb yuav tsum txheeb xyuas txhua txoj hauv kev, zam qhov "ntsuab ntxiab", thiab txhawb cov kev daws teeb meem zoo ib puag ncig.
Thaum Lub Plaub Hlis 22, 2024, Hong Kong tau pib ua thawj theem ntawm kev siv cov kev cai lij choj hais txog kev tswj hwm cov khoom siv yas pov tseg thiab lwm yam khoom yas. Qhov no txhais tau hais tias nws raug txwv tsis pub muag thiab muab 9 hom khoom siv yas pov tseg uas muaj qhov me me thiab nyuaj rau rov ua dua tshiab (nrog nthuav dav polystyrene tableware, straws, stirrers, khob yas thiab ntim khoom noj, thiab lwm yam), nrog rau cov paj rwb swabs. , kaus npog, tsev so, thiab lwm yam. Cov khoom siv xws li cov khoom siv pov tseg pov tseg. Lub hom phiaj ntawm qhov kev txav no zoo yog los daws qhov kev puas tsuaj ib puag ncig los ntawm kev siv cov khoom yas ib zaug, thaum txhawb nqa cov tib neeg thiab cov lag luam hloov mus rau lwm qhov kev nyab xeeb thiab ruaj khov.
Cov scenes raws Hong Kong tus ntug dej hiav txwv suab lub tswb rau kev tiv thaiv ib puag ncig. Peb puas xav nyob hauv ib puag ncig zoo li no? Vim li cas lub ntiaj teb nyob ntawm no? Txawm li cas los xij, qhov tseem ceeb tshaj qhov kev txhawj xeeb yog tias Hong Kong cov yas rov ua dua tshiab yog tsawg heev! Raws li cov ntaub ntawv xyoo 2021, tsuas yog 5.7% ntawm cov khoom siv rov ua dua tshiab hauv Hong Kong tau rov ua haujlwm zoo. Tus lej txaus ntshai no tam sim no xav kom peb yuav tsum tau nqis tes ua tam sim ntawd los ntsib cov teeb meem ntawm cov pov tseg yas thiab nquag txhawb kev hloov pauv ntawm tib neeg mus rau kev siv ntau yam kev nyab xeeb thiab kev nyab xeeb.
Yog li dab tsi yog cov kev xaiv muaj txiaj ntsig?
Txawm hais tias muaj ntau yam kev lag luam tau nquag tshawb nrhiav cov khoom siv biodegradable xws li polylactic acid (PLA) lossis bagasse (cov khoom siv fiber ntau muab rho tawm los ntawm cov kab pheeb ces kaum) ua lub teeb ci ntawm kev cia siab los daws cov teeb meem ntawm cov pa phem, qhov teeb meem yog lub hauv paus yog los xyuas seb cov kev hloov no puas yog. ua tau ntau tus phooj ywg environmentally. Nws yog qhov tseeb tias cov khoom siv biodegradable yuav tawg thiab degrade sai dua, yog li txo qhov kev pheej hmoo ntawm kev ua qias tuaj mus tas li ntawm ib puag ncig los ntawm cov pov tseg yas. Txawm li cas los xij, qhov peb yuav tsum tsis txhob tsis quav ntsej yog tias cov roj tsev cog khoom tso tawm thaum lub sij hawm degradation ntawm cov ntaub ntawv no (xws li polylactic acid los yog ntawv) nyob rau hauv Hong Kong cov landfills yog ntau dua li cov tsoos plastics.
Xyoo 2020, Lub Neej Cycle Initiative tau ua tiav qhov kev tshuaj ntsuam meta. Kev tshuaj xyuas muab cov ntsiab lus zoo ntawm cov ntaub ntawv ntsuas lub neej ntawm ntau yam khoom ntim, thiab qhov xaus yog kev poob siab: bio-based plastics (biodegradable plastics) ua los ntawm cov khoom siv ntuj xws li cassava thiab pob kws muaj kev cuam tshuam tsis zoo rau ib puag ncig kev ua tau zoo hauv kev cuam tshuam. qhov loj me tsis zoo dua li cov yas fossil raws li peb xav tau
Cov thawv noj su ua los ntawm polystyrene, polylactic acid (pob kws), polylactic acid (tapioca starch)
Bio-based plastics tsis tas yuav zoo dua li fossil-based plastics. Vim li cas qhov no?
Ib qho laj thawj tseem ceeb yog tias theem kev ua liaj ua teb yog kim: kev tsim cov yas biodegradable (biodegradable plastics) yuav tsum muaj thaj chaw loj ntawm thaj av, cov dej ntau, thiab cov khoom siv tshuaj lom neeg xws li tshuaj tua kab thiab chiv, uas inevitably emissions rau av, dej thiab huab cua. .
Cov theem tsim khoom thiab qhov hnyav ntawm cov khoom nws tus kheej kuj yog qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej. Siv lub thawv noj su uas ua los ntawm bagasse ua piv txwv. Txij li thaum bagasse nws tus kheej yog ib qho khoom siv tsis zoo, nws qhov cuam tshuam rau ib puag ncig thaum lub sij hawm ua liaj ua teb yog me me. Txawm li cas los xij, cov txheej txheem tshuaj dawb tom qab ntawm bagasse pulp thiab cov dej khib nyiab tsim tawm tom qab ntxuav cov ntaub so ntswg tau muaj kev cuam tshuam tsis zoo hauv ntau qhov chaw xws li huab cua, tib neeg noj qab haus huv thiab ecological toxicity. Ntawm qhov tod tes, txawm hais tias cov khoom siv raw thiab kev tsim cov thawv polystyrene ua npuas ncauj (PS npuas lub thawv) kuj muaj cov txheej txheem tshuaj lom neeg thiab lub cev ntau, vim tias bagasse muaj qhov hnyav dua, nws ib txwm xav tau cov ntaub ntawv ntau dua, uas nyuaj heev. Qhov no tej zaum yuav ua rau muaj ntau dua emissions nyob rau tag nrho lub neej voj voog. Yog li ntawd, peb yuav tsum paub tias txawm hais tias cov txheej txheem ntawm kev tsim khoom thiab kev ntsuam xyuas ntawm cov khoom sib txawv sib txawv, nws yog ib qho nyuaj rau kev txiav txim siab qhov kev xaiv twg yog "kev xaiv zoo tshaj" rau kev siv ib leeg.
Yog li qhov no puas txhais tau tias peb yuav tsum hloov rov qab mus rau yas?
Lo lus teb tsis yog. Raws li cov kev tshawb pom tam sim no, nws tseem yuav tsum paub meej tias lwm txoj hauv kev rau cov yas kuj tuaj yeem raug nqi ntawm ib puag ncig. Yog tias cov kev xaiv siv ib zaug no tsis muab cov kev daws teeb meem uas peb cia siab rau, ces peb yuav tsum rov ntsuam xyuas qhov tsim nyog ntawm cov khoom siv ib zaug thiab tshawb nrhiav cov kev xaiv muaj peev xwm los txo lossis tsis txhob siv lawv. Tsoomfwv SAR tau siv ntau yam kev ntsuas, xws li teeb tsa lub sijhawm npaj, txhawb kev kawm thiab kev tshaj tawm rau pej xeem, thiab tsim kom muaj cov ntaub ntawv xov xwm los qhia lwm txoj hauv kev rau cov khoom siv yas ib zaug, txhua qhov cuam tshuam txog qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej uas cuam tshuam rau Hong Kong "yas". -dawb” txheej txheem, uas yog seb cov pej xeem Hong Kong puas kam txais cov kev xaiv no, xws li muab koj tus kheej lub raj mis dej thiab cov tais diav. Cov kev hloov pauv no tseem ceeb heev rau kev txhawb nqa kev ua neej nyob ib puag ncig.
Rau cov pej xeem uas hnov qab (lossis tsis kam) nqa lawv lub thawv, tshawb txog kev qiv thiab xa rov qab rau cov ntim khoom siv rov qab tau dhau los ua qhov kev daws teeb meem tshiab thiab ua tau. Los ntawm cov txheej txheem no, cov neeg siv khoom tuaj yeem qiv cov thawv rov qab tau yooj yim thiab xa rov qab mus rau qhov chaw xaiv tom qab siv. Piv nrog rau cov khoom siv pov tseg, nce tus nqi rov qab siv ntawm cov ntim khoom no, siv cov txheej txheem tu kom zoo, thiab txuas ntxiv ua kom zoo ntawm cov qauv qiv thiab rov qab tuaj yeem ua tau zoo ntawm qhov nruab nrab rov qab (80%, ~ 5 cycles) Txo cov pa roj carbon monoxide ( 12-22%), kev siv cov khoom siv (34-48%), thiab kev txuag dej siv tau los ntawm 16% mus rau 40%. Nyob rau hauv txoj kev no, BYO khob thiab rov siv lub thawv qiv nyiaj thiab xa rov qab tuaj yeem dhau los ua qhov kev xaiv zoo tshaj plaws hauv kev xa tawm thiab xa khoom.
Hong Kong txoj kev txwv tsis pub siv cov khoom siv yas ib zaug yog qhov tseem ceeb hauv kev daws cov teeb meem ntawm cov pa phem thiab kev puas tsuaj ib puag ncig. Txawm hais tias nws yog qhov tsis muaj tseeb kom tshem tawm cov khoom yas hauv peb lub neej, peb yuav tsum paub tias tsuas yog kev txhawb nqa cov khoom siv pov tseg tsis yog ib qho kev daws teeb meem thiab tej zaum kuj yuav ua rau muaj teeb meem ib puag ncig tshiab; ntawm qhov tsis sib xws, peb yuav tsum pab lub ntiaj teb tshem tawm ntawm kev ua qhev ntawm "yas" Qhov tseem ceeb yog los txhawb kev paub txog pej xeem: qhia txhua tus neeg nkag siab qhov twg kom tsis txhob siv cov yas thiab ntim khoom, thiab thaum twg los xaiv cov khoom siv rov qab siv dua, thaum siv zog rau. txo qis kev siv cov khoom siv ib zaug los txhawb kev noj qab haus huv, kev ua neej nyob ruaj khov.
