Bio-based plasticstau txais koob meej hnub no vim lawv cov biodegradability thiab cov peev txheej txuas ntxiv mus.Bio-based plastics yog tsim los ntawm ntau qhov chaw xws li pob kws, taum pauv thiab qab zib pas nrig.Cov ntaub ntawv no yog siv los hloov cov fossil fuel plastics, uas ua rau muaj kev cuam tshuam loj rau cov teeb meem ib puag ncig hauv ntiaj teb niaj hnub no.Txawm li cas los xij, lawv cov txheej txheem tsim khoom thiab kev cuam tshuam ib puag ncig, nrog rau lawv cov kev ua tau zoo thiab kev siv, tseem muaj kev sib tw hauv kev lag luam.
Cov txheej txheem tsim khoom ntawm bio-based plastics feem ntau yuav tsum tau siv sijhawm ntau thiab siv zog ntau dua li cov khoom siv niaj hnub.Cov khoom siv raw siv los tsim cov yas no tau txais cov tshuaj enzymatic lossis tshuaj lom neeg los tsim cov qauv polymer uas xav tau.Tsis tas li ntawd, cov txheej txheem no feem ntau koom nrog kev siv qhov kub thiab txias, uas tuaj yeem cuam tshuam qhov zoo ntawm cov khoom kawg.Txawm li cas los xij, txawm tias muaj kev sib tw los ntawm lawv cov txheej txheem tsim khoom,bio-based plasticstau nce siv los tsim cov khoom muaj txiaj ntsig.
Ib qho txiaj ntsig tseem ceeb ntawm bio-based plastics yog lawv cov kev cuam tshuam ib puag ncig.Bio-raws li plastics muaj tsawg dua cov pa hluav taws xob hauv tsev cog khoom ntau dua li cov khoom siv niaj hnub.Lawv kuj yog biodegradable, uas txhais tau hais tias lawv tawg mus rau hauv lawv cov khoom ntuj hauv ib lub sijhawm.Piv txwv li,hnab khoom noj, ntim khoom noj, lub raj mis, taisthiabkhobua los ntawm bio-raws li plastics muab kev xaiv ntsuab dua vim tias lawv tuaj yeem siv tau tom qab siv.
Bio-based plastics kuj muaj cov khoom tshwj xeeb thiab kev siv uas ua rau lawv zoo tagnrho rau ntau yam kev siv.Piv txwv li, bio-based plastics yog cov khoom siv ruaj khov thiab sib zog dua li cov khoom siv niaj hnub, ua rau lawv zoo tagnrho rau kev tsim cov food ntim thiab ntim.Tsis tas li ntawd, bio-based plastics kuj tuaj yeem ua rau ntau yam duab rau kev siv sib txawv.Cov khoom no ua rau lawv muaj lwm txoj hauv kev zoo rau cov yas yas.
Txawm hais tias muaj txiaj ntsig zoo ntawm bio-based plastics, lawv tus nqi saws me nyuam tseem qis.Txawm li cas los xij, qhov kev hloov pauv no.Qhov kev thov rausustainable thiab environmentally friendly khoomtab tom loj hlob, thiab vim li ntawd, ntau thiab ntau lub tuam txhab tab tom nrhiav los hloov cov yas yas nrog cov kev xaiv bio-based.Kev txais yuav ntawm bio-raws li plastics tuaj yeem ua rau kev lag luam tshiab thiab kev loj hlob ntawmcov khoom tshiab.
Hauv cov ntsiab lus, cov xwm txheej ntawm bio-based plastics hauv kev lag luam tau hloov pauv sai.Txawm hais tias muaj kev sib tw los ntawm cov txheej txheem tsim khoom thiab kev cuam tshuam ib puag ncig, bio-based plastics muab cov txiaj ntsig zoo uas tsis tuaj yeem tsis quav ntsej.Nws cov khoom tshwj xeeb thiab cov ntawv thov ua rau nws yog qhov zoo tshaj plaws rau lwm cov khoom siv yas, thaum muaj kev xav tau los ntawm cov neeg siv khoom xav siv cov kev xaiv zoo dua qub thiab ib puag ncig zoo.Los ntawmcov khoom noj khoom haus rau lub thawv, lub raj mis, lub tais thiab khob, bio-based plastics tau ua pov thawj tias lawv muaj nqis nyob rau hauv kev ua lag luam raws li ib qho kev xaiv zoo tshaj plaws rau cov khoom siv niaj hnub.
