Raws li tsab ntawv tshaj tawm 2019 ntawm Lub Xeev Kev Nyab Xeeb Ntiaj Teb tau tshaj tawm los ntawm United Nations thiab World Meteorological Organization (WMO), 2019 yog lub xyoo sov tshaj plaws thib ob ntawm cov ntaub ntawv, thiab 10 xyoo dhau los tau sov tshaj plaws hauv cov ntaub ntawv.
Australian hluav taws kub nyhiab hauv 2019 thiab kev sib kis hauv 2020 tau tsa tib neeg, thiab cia peb pib xav txog.
Peb tab tom pib pom cov tshuaj tiv thaiv kab mob tshwm sim los ntawm kev ua kom sov thoob ntiaj teb, cov dej khov yaj, dej nyab thiab dej nyab, kev hem thawj rau tsiaj ciaj sia, thiab kev cuam tshuam rau tib neeg kev noj qab haus huv…
Yog li ntawd, ntau thiab ntau tus neeg tau txais kev pab tau pib tshawb nrhiav cov pa roj carbon tsawg dua thiab ib puag ncig tus phooj ywg txoj kev ua neej nyob rau hauv thiaj li yuav qeeb qeeb ntawm lub ntiaj teb sov!Qhov ntawd yog siv cov khoom siv bio-based ntau dua!
1. Txo cov pa roj carbon dioxide emissions thiab alleviate lub tsev xog paj
Hloov cov tsoos petrochemicals nrog cov khoom siv bio-based tuaj yeem txo cov pa roj carbon dioxide.
Kev tsim tawm ntawmbio-based khoomemissions carbon dioxide tsawg dua li cov khoom siv roj av."Kev Tshawb Fawb Txog Kev Lag Luam ntawm Tebchaws Meskas Bio-based Cov Khoom Lag Luam (2019)" tau taw qhia tias, raws li EIO-LCA (Kev Ntsuas Lub Neej) qauv, hauv 2017, Tebchaws Meskas hauv 2017 vim yog kev tsim khoom thiab siv bio. -raws li cov khoom siv los hloov cov khoom siv roj av, fossil fuels Siv tau raug txo los ntawm 60%, lossis ntau npaum li 12.7 lab tons ntawm CO2-sib npaug ntawm tsev cog khoom roj emissions.
Cov txheej txheem pov tseg tom qab tom qab kawg ntawm cov khoom siv lub neej feem ntau kuj ua rau cov pa roj carbon dioxide emissions, tshwj xeeb tshaj yog cov khoom ntim yas ntxiv.
Thaum cov yas hlawv thiab tawg, carbon dioxide tawm.Cov pa roj carbon dioxide tso tawm los ntawm combustion los yog decomposition ntawm bio-based plastics yog cov pa roj carbon nruab nrab thiab yuav tsis nce cov pa roj carbon dioxide hauv huab cua;combustion los yog decomposition ntawm roj av-raws li cov khoom yuav tso carbon dioxide, uas yog ib tug zoo emission thiab yuav ua rau kom tag nrho cov pa roj carbon dioxide nyob rau hauv cov huab cua.
Yog li los ntawm kev siv cov khoom siv bio-raws li cov khoom siv roj av, cov pa roj carbon dioxide hauv cov huab cua raug txo.
2. Siv cov peev txheej txuas dua tshiab thiab txo qis kev vam khom roj
Kev lag luam bio-based feem ntau yog siv cov khoom siv txuas ntxiv dua tshiab (xws li cov nroj tsuag, cov khib nyiab organic) los tsim thiab hloov cov khoom siv uas siv petrochemical extracts.Piv nrog rau cov khoom siv roj av, nws cov khoom siv raw khoom yog ib puag ncig zoo.
Raws li Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Lag Luam Hauv Teb Chaws Asmeskas Bio-Based Products Industry (2019) daim ntawv tshaj tawm, Tebchaws Asmeskas tau txuag 9.4 lab barrels roj los ntawm kev tsim cov khoom siv bio-based.Ntawm lawv, kev siv bio-based plastics thiab bio thiab ntim khoom tau txo qis li ntawm 85,000-113,000 barrels roj.
Tuam Tshoj muaj ib thaj chaw loj heev thiab muaj kev nplua nuj ntawm cov nroj tsuag.Txoj kev loj hlob muaj peev xwm ntawm kev lag luam bio-based yog loj, thaum kuv lub teb chaws cov peev txheej roj kuj tseem luv.
Hauv 2017, tag nrho cov roj tau txheeb xyuas hauv kuv lub tebchaws tsuas yog 3.54 billion tons, thaum kuv lub teb chaws kev siv roj av hauv 2017 yog 590 lab tons.
Txhawb kev tsim khoom thiab siv cov khoom siv bio-raws li yuav txo tau qhov kev cia siab ntawm cov roj thiab txo qhov kev siv cov pa phem ntau dhau los ntawm kev siv lub zog fossil.
Kev nce ntawm bio-raws li kev lag luam tuaj yeem ua tau raws li qhov xav tau ntawm niaj hnub no txoj kev loj hlob ntawm ntsuab, ib puag ncig tus phooj ywg thiab kev lag luam ruaj khov.
3. Bio-based khoom, nyiam los ntawm environmentalists
Ntau thiab ntau tus neeg tab tom nrhiav kev ua neej nyob qis qis thiab ib puag ncig tus phooj ywg, thiab cov khoom siv bio-based siv cov khoom siv txuas ntxiv tau dhau los ua neeg nyiam ntawm cov neeg siv khoom.
* Kev tshawb fawb Unilever xyoo 2017 tau pom tias 33% ntawm cov neeg siv khoom yuav xaiv cov khoom uas muaj txiaj ntsig zoo hauv zej zog lossis ib puag ncig.Txoj kev tshawb no nug 2,000 tus neeg laus los ntawm tsib lub teb chaws, thiab ntau tshaj li ib feem tsib (21%) ntawm cov neeg teb hais tias yog tias ib qho khoom ntim thiab kev lag luam tau nthuav tawm nws daim ntawv pov thawj kev ruaj ntseg, xws li USDA daim ntawv lo, yuav nquag xaiv cov khoom lag luam.
* Accenture tau tshawb fawb 6,000 tus neeg siv khoom hauv North America, Europe thiab Asia thaum lub Plaub Hlis 2019 kom nkag siab txog lawv cov kev yuav khoom thiab kev siv cov khoom ntim khoom sib txawv.Cov txiaj ntsig tau pom tias 72% ntawm cov neeg teb hais tias lawv tau nquag yuav cov khoom lag luam ib puag ncig ntau dua li lawv tau tsib xyoos dhau los, thiab 81% tau hais tias lawv xav tias yuav yuav ntau ntawm cov khoom no hauv tsib xyoos tom ntej.zoo li peb muajbiobased tawv, 10% -80%, UP RAU KOJ.
4. Bio-based cov ntawv pov thawj
Lub ntiaj teb bio-based kev lag luam tau tsim rau ntau tshaj 100 xyoo.Txhawm rau txhawb txoj kev loj hlob ntawm kev lag luam bio-based, ASTM D6866, ISO 16620, EN 16640 thiab lwm yam kev ntsuas tau raug tsim tawm thoob ntiaj teb, uas tshwj xeeb yog siv rau kev tshawb nrhiav cov ntsiab lus bio-based hauv cov khoom siv bio-based.
Txhawm rau pab cov neeg siv khoom pom cov khoom zoo thiab zoo bio-based, raws li saum toj no peb cov qauv kev lees paub thoob ntiaj teb, USDA bio-based cov ntawv tseem ceeb, OK Biobased, DIN CERTCO, Kuv ntsuab thiab UL bio-based cov ntawv pov thawj daim ntawv lo tau launched ib tug tom qab lwm.
Rau yav tom ntej
Nyob rau hauv cov ntsiab lus ntawm qhov tsis txaus ntawm cov khoom siv roj thoob ntiaj teb thiab kev siv zog ntawm lub ntiaj teb ua kom sov.Bio-based cov khoom lag luam yog ua raws li kev txhim kho thiab kev siv cov peev txheej txuas ntxiv mus, tsim kom muaj kev lag luam ruaj khov thiab zoo ib puag ncig "ntsuab kev lag luam", txo cov pa roj carbon dioxide emissions, txo cov nyhuv tsev cog khoom, thiab hloov cov peev txheej petrochemical, ib kauj ruam rau hauv koj lub neej txhua hnub.
Xav txog yav tom ntej, lub ntuj tseem xiav, qhov kub thiab txias tsis nce ntxiv, dej nyab tsis muaj dej nyab, tag nrho cov no pib nrog kev siv cov khoom siv bio-based!
