Raws li tsab ntawv tshaj tawm xyoo 2019 txog Lub Xeev Huab Cua Thoob Ntiaj Teb uas tau tshaj tawm los ntawm United Nations thiab Lub Koom Haum Huab Cua Thoob Ntiaj Teb (WMO), xyoo 2019 yog xyoo thib ob sov tshaj plaws hauv cov ntaub ntawv, thiab 10 xyoo dhau los no yog xyoo sov tshaj plaws hauv cov ntaub ntawv.
Cov hluav taws kub hauv tebchaws Australia xyoo 2019 thiab kev sib kis thoob plaws xyoo 2020 tau ua rau tib neeg sawv, thiab cia peb pib xav txog.
Peb tab tom pib pom qhov kev cuam tshuam saw hlau uas tshwm sim los ntawm kev sov ntawm lub ntiaj teb, cov dej khov yaj, kev qhuav thiab dej nyab, kev hem thawj rau kev ciaj sia ntawm cov tsiaj txhu, thiab kev cuam tshuam rau tib neeg kev noj qab haus huv ...
Yog li ntawd, cov neeg siv khoom ntau zuj zus pib tshawb nrhiav txoj kev ua neej uas tsis muaj carbon ntau thiab tsis ua rau ib puag ncig puas tsuaj kom qeeb qeeb qhov kev kub ntawm lub ntiaj teb! Qhov ntawd yog kev siv cov khoom siv bio-based ntau dua!
1. Txo cov pa roj carbon dioxide thiab txo cov teebmeem ntawm lub ntiaj teb sov
Kev hloov cov roj av ib txwm muaj nrog cov khoom siv bio-based tuaj yeem txo cov pa roj carbon dioxide.
Kev tsim khoom ntawmcov khoom siv bio-basedtso tawm cov pa roj carbon dioxide tsawg dua li cov khoom siv roj av. "Kev Tshawb Fawb Txog Kev Cuam Tshuam Kev Lag Luam ntawm Kev Lag Luam Khoom Siv Bio-based hauv Tebchaws Meskas (2019)" tau taw qhia tias, raws li tus qauv EIO-LCA (Kev Ntsuam Xyuas Lub Neej Lub Neej) hauv xyoo 2017, Tebchaws Meskas hauv xyoo 2017 vim yog kev tsim khoom thiab kev siv cov khoom siv bio-based los hloov cov khoom siv roj av, kev siv roj fossil tau raug txo los ntawm 60%, lossis ntau npaum li 12.7 lab tons ntawm CO2-equivalent greenhouse gas emissions.
Cov txheej txheem pov tseg tom qab lub sijhawm siv khoom tas feem ntau ua rau muaj cov pa roj carbon dioxide, tshwj xeeb tshaj yog cov ntim yas seem.
Thaum cov yas kub hnyiab thiab tawg, cov pa roj carbon dioxide yuav raug tso tawm. Cov pa roj carbon dioxide uas tso tawm los ntawm kev hlawv lossis lwj ntawm cov yas bio-based yog cov pa roj carbon nruab nrab thiab yuav tsis ua rau cov pa roj carbon dioxide ntau ntxiv rau hauv huab cua; kev hlawv lossis lwj ntawm cov khoom siv roj av yuav tso cov pa roj carbon dioxide, uas yog qhov tso pa tawm zoo thiab yuav ua rau tag nrho cov pa roj carbon dioxide ntau ntxiv rau hauv huab cua.
Yog li ntawd, los ntawm kev siv cov khoom siv bio-based es tsis txhob siv cov khoom siv roj av, cov pa roj carbon dioxide hauv huab cua raug txo qis.
2. Siv cov peev txheej rov ua dua tshiab thiab txo kev vam khom roj
Kev lag luam bio-based feem ntau siv cov khoom siv rov ua dua tshiab (piv txwv li cov nroj tsuag, cov khib nyiab organic) los tsim thiab hloov cov khoom ib txwm siv cov tshuaj petrochemical extracts. Piv rau cov khoom siv roj av, nws cov khoom siv raw yog cov phooj ywg zoo rau ib puag ncig.
Raws li daim ntawv qhia txog Kev Tshawb Fawb Txog Kev Cuam Tshuam Txog Kev Lag Luam ntawm Tebchaws Meskas Cov Khoom Siv Bio-Based (2019), Tebchaws Meskas tau txuag tau 9.4 lab lub thoob roj los ntawm kev tsim cov khoom siv bio-based. Ntawm lawv, kev siv cov yas bio-based thiab bio thiab cov ntim khoom tau txo qis li ntawm 85,000-113,000 lub thoob roj.
Tuam Tshoj muaj thaj chaw dav heev thiab muaj ntau yam khoom siv cog qoob loo. Lub peev xwm tsim kho ntawm kev lag luam bio-based yog loj heev, thaum kuv lub teb chaws cov khoom siv roj tsawg heev.
Xyoo 2017, tag nrho cov roj uas tau txheeb xyuas hauv kuv lub tebchaws tsuas yog 3.54 billion tons xwb, thaum kuv lub tebchaws siv roj av nyoos xyoo 2017 yog 590 lab tons.
Kev txhawb nqa kev tsim khoom thiab kev siv cov khoom siv bio-based yuav txo qhov kev vam khom roj thiab txo cov pa phem uas tshwm sim los ntawm kev siv lub zog fossil.
Kev nce qib ntawm kev lag luam bio-based tsuas yog ua tau raws li qhov xav tau ntawm kev txhim kho niaj hnub no ntawm kev lag luam ntsuab, tus phooj ywg ib puag ncig thiab kev lag luam ruaj khov.
3. Cov khoom siv bio-based, uas cov neeg tiv thaiv ib puag ncig nyiam
Muaj ntau tus neeg tab tom nrhiav lub neej uas tsis muaj carbon ntau thiab zoo rau ib puag ncig, thiab cov khoom siv bio-based uas siv cov khoom siv rov ua dua tshiab tau nrov zuj zus ntawm cov neeg siv khoom.
* Ib txoj kev tshawb fawb xyoo 2017 ntawm Unilever qhia tau hais tias 33% ntawm cov neeg siv khoom yuav xaiv cov khoom uas muaj txiaj ntsig zoo rau zej zog lossis ib puag ncig. Txoj kev tshawb fawb tau nug 2,000 tus neeg laus los ntawm tsib lub tebchaws, thiab ntau dua ib feem tsib (21%) ntawm cov neeg teb tau hais tias yog tias cov khoom ntim khoom thiab kev lag luam pom tseeb tias nws daim ntawv pov thawj kev ruaj khov, xws li daim ntawv lo USDA, yuav xaiv cov khoom zoo li no.
*Accenture tau soj ntsuam 6,000 tus neeg siv khoom hauv North America, Tebchaws Europe thiab Asia thaum lub Plaub Hlis 2019 kom nkag siab txog lawv txoj kev yuav khoom thiab kev siv cov khoom ntim hauv cov ntaub ntawv sib txawv. Cov txiaj ntsig tau qhia tias 72% ntawm cov neeg teb tau hais tias lawv tau yuav cov khoom uas zoo rau ib puag ncig ntau dua li tsib xyoos dhau los, thiab 81% tau hais tias lawv xav tias yuav yuav ntau cov khoom no hauv tsib xyoos tom ntej. xws li peb tautawv nqaij biobased, 10%-80%, NYOB RAU KOJ.
4. Daim ntawv pov thawj txog cov khoom siv bio-based
Kev lag luam thoob ntiaj teb uas muaj cov khoom siv bio-based tau tsim kho tau ntau tshaj 100 xyoo. Txhawm rau txhawb kev txhim kho ntawm kev lag luam bio-based, ASTM D6866, ISO 16620, EN 16640 thiab lwm yam qauv xeem tau tsim tawm thoob ntiaj teb, uas yog siv tshwj xeeb rau kev kuaj pom cov ntsiab lus bio-based hauv cov khoom bio-based.
Yuav kom pab cov neeg siv khoom nrhiav tau cov khoom siv bio-based tiag tiag thiab zoo, raws li peb tus qauv kev xeem thoob ntiaj teb uas tau lees paub saum toj no, cov ntawv lo USDA bio-based priority, OK Biobased, DIN CERTCO, I'm green thiab UL bio-based content certification tau tsim tawm ib qho tom qab ib qho.
Mus rau yav tom ntej
Nyob rau hauv cov ntsiab lus ntawm kev tsis txaus ntawm cov peev txheej roj thoob ntiaj teb thiab kev kub ntxhov ntawm lub ntiaj teb. Cov khoom siv bio-based yog raws li kev txhim kho thiab kev siv cov peev txheej rov ua dua tshiab, tsim kom muaj kev lag luam "ntsuab" uas ruaj khov thiab zoo rau ib puag ncig, txo cov pa roj carbon dioxide, txo cov teebmeem ntawm lub tsev cog khoom, thiab hloov cov peev txheej petrochemical, ib kauj ruam zuj zus rau hauv koj lub neej txhua hnub.
Xav txog yav tom ntej, lub ntuj tseem xiav, qhov kub tsis nce siab lawm, dej nyab tsis nyab lawm, txhua yam no pib nrog kev siv cov khoom siv bio-based!
