Cov kws tshaj lij tam sim no hu rau kev tsom mus rau kev siv hluav taws xob ntau ntxiv thiab kev coj ua ua ntej noj thaum nws los txog rau kev ntim khoom kom txo tau cov pov tseg pov tseg.
Greenhouse gas (GHG) tshwm sim los ntawm cov roj fossil siab thiab kev tswj xyuas cov pov tseg tsis zoo yog ob qho ntawm cov teeb meem ua rau Africa cov txheej txheem kev lag luam, thiab yog li qhov kev kub ntxhov ntawm innovating cov kev daws teeb meem uas tsis yog tsuas yog tiv thaiv kev ruaj ntseg ntawm kev lag luam tab sis ua kom cov tuam txhab lag luam thiab cov neeg ua si nyob rau hauv kev lag luam. tus nqi saw ntawm kev lag luam tsawg tsawg thiab cov nyiaj tau los siab.
Cov kws tshaj lij tam sim no hu rau kev ua kom pom tseeb ntawm kev siv hluav taws xob thiab kev coj ua ua ntej noj thaum nws los txog rau kev ntim khoom kom txo tau cov pov tseg pov tseg yog tias thaj av yuav ua rau muaj txiaj ntsig zoo rau net xoom los ntawm 2050 thiab nthuav dav ntawm cov txheej txheem kev lag luam txheej txheej.
South Africa
Nyob rau hauv South Africa, qhov kev cia siab hnyav ntawm cov pob txha-tsav lub zog rau lub zog txheej cov nroj tsuag kev ua haujlwm thiab tsis muaj cov txheej txheem pov tseg kom zoo thiab siv tau tau yuam qee lub teb chaws cov tuam txhab txheej txheej xaiv rau kev nqis peev hauv kev siv hluav taws xob huv thiab ntim cov kev daws teeb meem. uas tuaj yeem rov siv dua thiab rov siv dua los ntawm ob tus neeg tsim khoom thiab lawv cov neeg siv khoom.
Piv txwv li, Cape Town-based Polyoak Ntim, ib lub tuam txhab tshwj xeeb hauv kev tsim thiab tsim khoom ntawm ib puag ncig lub luag haujlwm nruj yas ntim rau cov khoom noj, dej haus thiab kev lag luam kev siv, hais tias kev hloov pauv huab cua thiab cov pa phem, uas yog ib feem ntawm kev tsim khoom suav nrog. kev lag luam coatings, yog ob ntawm lub ntiaj teb "cov teeb meem phem" tab sis rau cov kev daws teeb meem twg muaj rau cov neeg ua lag luam tshiab coatings.
Cohn Gibb, tus thawj coj ntawm lub tuam txhab muag khoom, tau hais hauv Johannesburg thaum Lub Rau Hli 2024 lub zog lag luam suav txog ntau dua 75% ntawm cov pa hluav taws xob hauv tsev cog khoom nrog lub ntiaj teb lub zog tau los ntawm fossil fuels. Hauv South Africa, fossil fuels suav txog li 91% ntawm lub teb chaws tag nrho lub zog piv rau 80% thoob ntiaj teb nrog cov thee dominating lub teb chaws hluav taws xob.
Nws hais tias "South Africa yog 13th loj tshaj plaws tsev cog khoom tso pa tawm thoob ntiaj teb nrog cov pa roj carbon ntau tshaj plaws ntawm G20 lub teb chaws," nws hais.
Eskom, South Africa lub zog siv hluav taws xob, "yog tus tsim khoom lag luam thoob ntiaj teb ntawm GHG vim nws tso tawm sulfur dioxide ntau dua li Asmeskas thiab Tuam Tshoj ua ke," Gibb saib.
Cov emissions siab ntawm sulfur dioxide muaj feem cuam tshuam rau South Africa txoj kev tsim khoom thiab cov tshuab ua rau qhov tsim nyog rau kev xaiv lub zog huv.
Lub siab xav txhawb nqa thoob ntiaj teb kev siv zog los txo cov fossil fuel-driven emissions thiab txo qis ntawm tus kheej cov nqi khiav lag luam, nrog rau txo qis kev pheej hmoo loadshedding los ntawm Eskom tus nqi, tau tsav Polyoak mus rau lub zog tauj dua tshiab uas yuav pom lub tuam txhab tsim muaj ze li ntawm 5.4 lab kwh txhua xyoo. .
Lub zog huv uas tau tsim "yuav txuag 5,610 tons ntawm CO2 emissions txhua xyoo uas yuav xav tau 231,000 tsob ntoo hauv ib xyoos los nqus," Gibb hais.
Txawm hais tias qhov kev siv hluav taws xob txuas ntxiv tshiab tsis txaus los txhawb Polyoak txoj haujlwm, lub tuam txhab tau nqis peev hauv lub tshuab hluav taws xob kom ntseeg tau tias tsis muaj hluav taws xob cuam tshuam thaum lub sij hawm thauj khoom rau kev ua tau zoo tshaj plaws.
Lwm qhov, Gibb hais tias South Africa yog ib lub tebchaws uas muaj kev tswj hwm pov tseg phem tshaj plaws hauv ntiaj teb thiab nws yuav siv cov txheej txheem ntim khoom tshiab los ntawm cov tuam txhab coatings kom txo tau cov khoom pov tseg uas tsis tuaj yeem rov qab siv dua thiab tsis rov ua dua tshiab hauv lub tebchaws uas muaj txog 35%. ntawm tsev neeg tsis muaj daim ntawv pov tseg. Ib feem loj ntawm cov khoom pov tseg uas tsim tawm raug muab pov tseg tsis raug cai thiab muab pov tseg rau hauv reivers feem ntau nthuav tawm cov chaw tsis raug cai, raws li Gibb.
Reusable Ntim
Qhov kev sib tw loj tshaj plaws ntawm kev tswj cov khib nyiab yog los ntawm cov yas thiab txheej ntim cov tuam txhab thiab cov chaw muag khoom muaj lub sijhawm los txo lub nra ntawm ib puag ncig los ntawm kev ntim khoom siv ntev ntev uas tuaj yeem siv tau yooj yim yog tias xav tau.
Xyoo 2023, South Africa Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb thiab Kev Nkoj Nkoj thiab Ib puag ncig tau tsim lub teb chaws cov lus qhia txog kev ntim khoom uas npog plaub pawg ntawm cov khoom ntim cov dej ntws ntawm cov hlau, iav, ntawv thiab yas.
Cov lus qhia, lub tuam tsev hais tias, yog los pab "txo cov ntim ntim xaus rau hauv qhov chaw pov tseg los ntawm kev txhim kho cov khoom tsim, ua kom zoo ntawm kev tsim khoom thiab txhawb kev tiv thaiv pov tseg."
"Ib lub hom phiaj tseem ceeb ntawm cov lus qhia ntim no yog los pab cov neeg tsim khoom hauv txhua hom kev ntim khoom nrog kev nkag siab zoo txog kev cuam tshuam ib puag ncig ntawm lawv cov kev txiav txim siab tsim, yog li txhawb nqa kev coj ua zoo ib puag ncig yam tsis txwv kev xaiv," said yav dhau los DFFE tus thawj coj Creecy Barbara, uas. tau txij li thaum tau tsiv mus rau department of transport.
Ntawm Polyoak, Gibb hais tias, lub tuam txhab kev tswj hwm tau thawb ua ntej nrog nws cov ntawv ntim khoom uas tsom mus rau "rov siv cov thawv ntawv kom txuag ntoo." Polyoak's cartons yog tsim los ntawm qib zaub mov carton board rau kev nyab xeeb.
Gibb hais tias "Qhov nruab nrab nws yuav siv 17 tsob ntoo los tsim ib tuj ntawm carbon board," Gibb hais.
"Peb cov phiaj xwm xa rov qab los pab txhawb kev rov siv dua ntawm txhua lub thawv rau qhov nruab nrab tsib zaug," nws hais ntxiv, hais txog 2021 lub sijhawm tseem ceeb ntawm kev yuav 1600 tons ntawm cov thawv tshiab, rov siv dua li no txuag 6,400 ntoo.
Gibb kwv yees nyob rau hauv ntau tshaj ib xyoos, reusing cartons txuag 108,800 ntoo, sib npaug rau ib lab ntoo hauv 10 xyoo.
DFFE kwv yees ntau dua 12 lab tons ntawm cov ntawv thiab cov ntawv ntim tau rov qab los rau kev rov ua dua tshiab hauv lub tebchaws hauv 10 xyoo dhau los nrog tsoomfwv hais tias ntau dua 71% ntawm cov ntaub ntawv rov qab tau thiab ntim tau raug sau rau xyoo 2018, suav txog 1,285 lab tons.
Tab sis qhov kev sib tw loj tshaj plaws uas ntsib South Africa, ib yam li nyob hauv ntau lub tebchaws African, yog qhov kev txwv tsis pub pov tseg ntawm cov yas, tshwj xeeb tshaj yog cov yas pellets lossis nurdles.
Gibb tau hais tias "Kev lag luam yas yuav tsum tiv thaiv kev nchuav ntawm cov yas pellets, flakes lossis hmoov rau hauv ib puag ncig los ntawm cov chaw tsim khoom thiab xa tawm," Gibb hais.
Tam sim no, Polyoak tab tom khiav ib qho kev sib tw hu ua 'catch ntawd pellet tsav' txhawm rau tiv thaiv cov yas pellets ua ntej lawv nkag mus rau South Africa cov dej nag los.
"Hmoov tsis zoo, cov yas pellets tau ua yuam kev ua zaub mov qab rau ntau cov ntses thiab noog tom qab hla dej los ntawm cov dej nag uas lawv ua rau lawv txoj kev mus rau hauv peb cov dej ntws ntws mus rau hauv dej hiav txwv thiab thaum kawg ntxuav mus rau peb cov ntug hiav txwv dej."
Cov yas pellets yog tsim los ntawm microplastics tau los ntawm cov log tsheb plua plav thiab microfiber los ntawm kev ntxuav thiab ziab kom qhuav ntawm nylon thiab polyester khaub ncaws.
Yam tsawg kawg ntawm 87% ntawm cov khoom siv microplastics tau pauv cov cim kev lag luam (7%), microfibers (35%), cov plua plav hauv nroog (24%), log tsheb (28%) thiab nurdles (0.3%).
Qhov xwm txheej zoo li yuav tshwm sim raws li DFFE hais tias South Africa tsis muaj "tsis muaj kev tswj xyuas cov khoom siv pov tseg loj rau kev sib cais thiab ua cov ntim khoom biodegradable thiab compostable.
"Raws li qhov tshwm sim, cov ntaub ntawv no tsis muaj txiaj ntsig zoo rau cov khoom pov tseg raug cai lossis tsis raug cai, yog li cov khoom lag luam yuav nyob twj ywm hauv ib puag ncig lossis zoo tshaj plaws, xaus rau hauv qhov chaw pov tseg," DFFE tau hais.
Qhov no yog txawm hais tias muaj nyob rau ntawm Consumer Protection Act Tshooj 29 thiab 41 thiab Standards Act 2008 Tshooj 27(1) & {2) uas txwv tsis pub dag, dag lossis dag ntxias hais txog cov khoom xyaw lossis cov yam ntxwv ua haujlwm nrog rau cov lag luam los ntawm kev dag ntxias lossis kev ua haujlwm hauv ib yam uas zoo li "los tsim kev xav tias cov khoom ua raws li South African National Standard lossis lwm yam kev tshaj tawm ntawm SABS."
Nyob rau lub sijhawm luv mus rau nruab nrab, DFFE hais kom cov tuam txhab txo qis kev cuam tshuam ib puag ncig ntawm cov khoom thiab cov kev pabcuam los ntawm lawv lub neej tag nrho "raws li kev hloov pauv huab cua thiab kev ruaj khov yog cov teeb meem loj tshaj plaws niaj hnub no, nws yog qhov tseem ceeb rau."
