Bioplastics yog tsim los ntawm bio-based polymers thiab yog tsim los siv cov khoom siv ruaj khov thiab txuas ntxiv dua tshiab, xws li pob kws los yog qab zib.
Bioplastics ua haujlwm ze li ntawm qhov sib npaug ntawm cov yas ua los ntawm cov roj av, thiab lawv tau dhau los ntawm lawv cov npe nrov raws li cov khoom ntim.Qhov kev kwv yees tseem ceeb los ntawm cov kws tshawb fawb yog tias bioplastics tuaj yeem txiav carbon dioxide emissions ntau li 70%.Lawv kuj yog 65% ntau lub zog txuag thaum tsim khoom, ua rau lawv muaj kev xaiv ntau dua ecologically lub luag haujlwm.
Txawm hais tias muaj ntau hom bioplastics, polylactic acid (PLA)-raws li ntim khoom yog feem ntau siv ntau yam.Rau cov roasters nrhiav cov khoom zoo nkauj tsis yog ib puag ncig lub luag haujlwm los ntim lawv cov kas fes, PLA muaj qhov ua tau zoo heev.
Txawm li cas los xij, vim tias PLA hnab kas fes tsuas yog rov ua dua thiab biodegradable nyob rau hauv cov xwm txheej tshwj xeeb, lawv yooj yim rau kev ntxuav dej ntsuab.Roasters thiab kas fes cafes yuav tsum qhia cov neeg siv khoom txog qhov xwm txheej ntawm PLA ntim thiab pov tseg kom zoo raws li kev tswj hwm tau nce mus rau kev loj hlob sai ntawm bioplastics sector.
Nyeem ntxiv kom kawm paub kev sib txuas lus rau cov neeg siv khoom ntev npaum li cas rau PLA kas fes hnab kom tawg.
Dab tsi yog PLA?
Kev lag luam hluavtaws fiber ntau tau hloov pauv los ntawm Wallace Carothers, tus kws tshawb fawb Asmeskas thiab tus tsim khoom, uas paub zoo tshaj plaws los tsim cov nylon thiab polyethylene terephthalate (PET).
Tsis tas li ntawd, nws pom PLA.Carothers thiab lwm cov kws tshawb fawb pom tau tias cov kua qaub ntshiab lactic tuaj yeem hloov pauv thiab ua ke rau hauv cov polymers.
Cov khoom noj khoom haus ib txwm muaj, flavorings, thiab curing agents muaj xws li lactic acid.Los ntawm fermenting nws nrog starch thiab lwm yam polysaccharides los yog qab zib ntau nyob rau hauv cov nroj tsuag, nws muaj peev xwm hloov mus rau hauv polymers.
Cov txiaj ntsig polymer yuav raug siv los tsim cov khoom tsis muaj tshuaj lom, biodegradable thermoplastic filaments.
Nws cov neeg kho tshuab thiab thermal kuj tseem muaj kev txwv.Raws li qhov tshwm sim, nws tau ploj mus rau polyethylene terephthalate, uas muaj ntau dua nyob rau lub sijhawm.
Txawm li cas los xij, PLA tuaj yeem ua haujlwm hauv biomedicine vim nws qhov hnyav thiab biocompatibility, tshwj xeeb tshaj yog cov ntaub so ntswg engineering scaffold khoom, sutures, lossis screws.
Cov tshuaj no tuaj yeem nyob hauv qhov chaw ib ntus ua ntej degrading spontaneously thiab tsis muaj kev puas tsuaj ua tsaug rau PLA.
Sij hawm dhau mus, nws tau pom tias kev sib xyaw PLA nrog qee cov hmoov txhuv nplej siab tuaj yeem txhim kho nws cov kev ua tau zoo thiab biodegradability thaum txo cov nqi tsim khoom.Qhov no tau pab txhawb rau kev tsim PLA zaj duab xis uas tuaj yeem siv los tsim cov ntim tau yooj yim thaum ua ke nrog kev txhaj tshuaj molding thiab lwm cov txheej txheem yaj.
Cov kws tshawb fawb tau cia siab tias PLA yuav dhau los ua tus nqi tsim nyog los tsim, uas yog xov xwm zoo rau cov khw kas fes thiab roasters.
Raws li qhov kev thov rau cov ntim tau yooj yim tau nce vim yog cov neeg siv khoom xaiv rau cov khoom ntim khoom ib puag ncig thiab rov ua dua tshiab, PLA kev lag luam thoob ntiaj teb xav tias yuav dhau $ 2.7 lab los ntawm 2030.
Tsis tas li ntawd, PLA tuaj yeem tsim los ntawm kev ua liaj ua teb thiab hav zoov pov tseg kom tsis txhob muaj kev sib tw nrog cov khoom noj.
Nws siv sijhawm ntev npaum li cas rau PLA lub hnab kas fes kom tawg?
Cov tshuaj polymers ua los ntawm cov roj av tuaj yeem siv sijhawm txog ib txhiab xyoo kom decompose.
Hloov pauv, kev tawg ntawm PLA rau hauv cov pa roj carbon dioxide (CO2) thiab dej yuav siv sijhawm li ntawm rau lub hlis mus rau ob xyoos.
Txawm hais tias qhov no, PLA khaws cov chaw tseem tab tom hloov kho rau kev lag luam bioplastics loj hlob.Tsuas yog 16% ntawm cov khoom khib nyiab tam sim no tau raug sau hauv European Union.
Vim tias muaj ntau ntawm PLA ntim, nws muaj peev xwm ua rau nws kis tau ntau yam dej khib nyiab, sib xyaw nrog cov khoom siv niaj hnub, thiab xaus rau hauv qhov chaw pov tseg lossis qhov cub.
Lub hnab kas fes ua los ntawm PLA yuav tsum tau muab pov tseg ntawm qhov chaw tshwj xeeb hauv kev tsim cov khoom sib xyaw uas lawv tuaj yeem decompose tag nrho.Ua tsaug rau qee qhov ntsuas kub thiab cov pa roj carbon, oxygen, thiab nitrogen, cov txheej txheem no tuaj yeem siv sijhawm txog 180 hnub.
Yog tias PLA ntim tsis degrade nyob rau hauv cov xwm txheej no, cov txheej txheem yuav tsim microplastics, uas tsis zoo rau ib puag ncig.
Vim tias lub ntim kas fes tsis tshua tsim los ntawm ib qho khoom siv, cov txheej txheem yuav nyuaj dua.Piv txwv li, feem ntau ntawm cov hnab kas fes muaj xws li zippers, tin ties, los yog degassing li qub.
Nws kuj tseem tuaj yeem raug kab los muab ib txheej ntxiv ntawm kev tiv thaiv kev tiv thaiv.Vim tias muaj peev xwm ua tau txhua yam yuav tsum tau ua tiav nyias, yam zoo li no yuav ua rau PLA hnab kas fes nyuaj rau pov tseg.
Kev siv PLA hnab kas fes
Rau ntau tus roasters, siv PLA los ntim kas fes yog qhov kev xaiv ua tau zoo thiab muaj txiaj ntsig zoo.
Ib qho txiaj ntsig tseem ceeb yog tias ob qho tib si hauv av thiab roasted kas fes yog cov khoom qhuav.Qhov no txhais tau tias tom qab siv, PLA hnab kas fes tsis muaj cov kab mob thiab tsis tas yuav tsum tau ntxuav.
Cov neeg siv khoom kuj tseem tuaj yeem pab cov roasters thiab khw kas fes tau lees paub tias PLA ntim tsis tuaj yeem ua rau hauv qhov chaw pov tseg.Cov neeg siv khoom yuav tsum nkag siab qhov twg rov ua dua tshiab rau hauv PLA kas fes hnab yuav tsum tau muab tso rau tom qab siv.Qhov no tuaj yeem ua tiav los ntawm kev muab cov lus qhia rau kev sib cais thiab rov ua dua tshiab ntawm lub ntim kas fes.
Yog tias tsis muaj PLA sau thiab ua cov chaw muaj nyob rau hauv cheeb tsam, roasters thiab kas fes cafes yuav txhawb kom cov neeg siv khoom xa rov qab lawv cov ntim ntim hauv kev pauv rau kas fes pheej yig dua.
Tom qab ntawd, cov thawj coj hauv tuam txhab tuaj yeem lav tias cov hnab kas fes PLA khoob raug xa mus rau qhov chaw rov ua dua tshiab.
PLA ntim pov tseg tej zaum yuav yooj yim dua yav tom ntej.Qhov tseem ceeb, 175 lub teb chaws tau cog lus tias yuav tsum tsis txhob muaj kuab paug yas ntawm United Nations Environment Assembly hauv 2022.
Raws li qhov tshwm sim, yav tom ntej, tsoomfwv ntau dua tuaj yeem nqis peev hauv kev tsim kho vaj tse uas xav tau los ua cov khoom siv bioplastics.
Kev txav mus rau kev siv cov khoom siv bioplastics tau nce zuj zus vim tias cov pov tseg yas txuas ntxiv ua rau ib puag ncig puas tsuaj thiab cuam tshuam rau tib neeg thiab tsiaj noj qab haus huv.
Los ntawm kev koom tes nrog tus kws tshaj lij ntim kas fes, koj tuaj yeem siv cov ntim khoom hauv eco uas muaj kev cuam tshuam tiag tiag thiab tsis ua rau muaj teeb meem tshiab rau leej twg.
Cyan Pak muag ntau lub hnab kas fes uas tuaj yeem hloov kho nrog PLA sab hauv.Thaum ua ke nrog kraft ntawv, nws tsim ib qho kev xaiv biodegradable rau cov neeg siv khoom.
Peb lub ntim tseem muaj cov khoom siv rov ua dua tshiab, biodegradable, thiab compostable xws li cov ntawv nplej, uas yog txhua yam tsim los ntawm cov khoom siv txuas ntxiv.
Tsis tas li ntawd, peb tuaj yeem siv cov luam ntawv digital los kho lub hnab kas fes nrog kev sib cais thiab cov lus qhia rov ua dua tshiab.Peb tuaj yeem muab qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis (MOQs) rau ntim ntawm txhua qhov loj lossis cov khoom siv.
Degassing li qub uas tuaj yeem rov ua dua tshiab thiab tsis muaj BPA kuj muaj;lawv tuaj yeem muab rov ua dua nrog cov khoom ntim kas fes.Cov li qub no tsis tsuas yog ua cov khoom lag luam uas muaj txiaj ntsig zoo rau cov neeg siv khoom, tab sis kuj txo qis cov teeb meem cuam tshuam ntawm kev ntim kas fes rau ib puag ncig.
