Tam sim no, cov khoom siv bioplastics tsis tsuas yog pib nkag mus rau kev lag luam ntim hauv kev lag luam, tab sis kuj pib tawm tsam ntau yam kev lag luam, xws li kev lag luam tsheb. Tau ntev, ntau tus neeg ntseeg tias cov khoom siv yas thiab cov khoom lag luam yog cov neeg koom nrog kev ua kom ib puag ncig kev puas tsuaj thiab tua cov kab mob hauv ib puag ncig. Txawm li cas los xij, cov ntaub ntawv tshiab tsim tau yooj yim thiab rov ua dua tshiab cov khoom siv yas yuav coj cov xov xwm zoo rau kev tiv thaiv ib puag ncig thiab kev cia siab rau kev tiv thaiv ib puag ncig.
Ua cov khoom siv tshiab hauv kev lag luam, bioplastics tau siv dav. Yav dhau los, cov khoom siv sab hauv tsheb feem ntau yog TPU yas raw khoom, nplaim taws retardant PP raw khoom, thiab lwm yam, tab sis tam sim no cov khoom lag luam sab hauv tsheb pib pib ua los ntawm cov khoom siv bioplastic. Raws li tus thawj coj tsom xam cov qauv txheej txheem, ntau cov neeg muab khoom siv hauv lub tsheb tsis xav siv cov khoom siv raw uas tuaj yeem muaj kev cuam tshuam loj thiab txhawb kev noj qab haus huv thiab kev tsim kho kom zoo. Cov khoom siv yas tau muab tso rau hauv kev tsim cov xov tooj ntawm tes, kev ntim cov yeeb yaj kiab, thiab lwm yam, tab sis kev lag luam tsheb kuj tseem txwv rau kev lag luam sab hauv tsheb, thiab kev nthuav dav ntawm cov khoom lag luam sab nraud tsheb tseem tab tom tsim.
Muaj ntau yam laj thawj vim li cas bioplastics tsis tuaj yeem siv dav hauv kev ua lag luam. Tam sim no, daim ntawv thov ntawm cov khoom lag luam sab hauv tsheb los ntawm cov tuam txhab tsheb thoob ntiaj teb tsis tau nthuav dav.
Tam sim no tsoomfwv tau pib xa qhov tseem ceeb rau kev txhawb nqa ntawm cov khoom yas poob qis. Tom qab lub sijhawm ntev ntawm nag lossis daus npau taws, cov khoom siv no, uas tau kawm txij li xyoo 1980, thaum kawg tau mus rau qhov chaw thiab maj mam paub tab. Hauv kev ntim khoom yas, hnab khib nyiab, yas zaj duab xis thiab lwm yam, yuav muaj coob tus bioplastics raw khoom nkag mus, thiab kev ua lag luam no kuj dav heev, kev siv khoom hauv thaj chaw no yog qhov loj txhua xyoo.
Qhov laj thawj yog vim li cas cov neeg bioplastics tom qab tau pib yog tias ntau ntawm cov khoom lag luam yas tsis kam rov qab ua dua tshiab thiab rov ua dua tshiab. Qhov no ua rau cov yas khib nyiab loj heev nkag mus rau hauv lub ntiaj teb ntuj. Cov khoom siv no tsis tuaj yeem zom thiab txo qis los ntawm qhov. Tshwj xeeb, qee cov ntaub ntawv yas yog tsim kom muaj cov khoom coj los tiv thaiv rau cov hom phiaj tshwj xeeb, yog li lawv tsis cog rau lub sijhawm ntev. Tej zaum nws yuav ua rau ploj zuj zus lossis poob qis. Txawm hais tias cov khoom siv bioplastic muaj cov khoom tsis zoo, tus nqi tsim tawm ntawm cov khoom siv biodegradable bioplastics yog siab dua qhov ntawm cov khoom siv raw yas zoo tib yam. Yog li ntawd, tsis muaj cuab kev kom zoo dua hauv tus nqi. Yog tias tsoomfwv tau muab kev txhawb nqa txoj cai, Kuv ntseeg tias nws yuav muaj peev xwm nkag mus tau tom khw tam sim ntawd.
Lub ntsiab yog vim li cas rau qhov kev thov loj ntawm bioplastics raw khoom yog tias nws yog lub zog-txuag thiab ib puag ncig. Txawm li cas los xij, nws qhov kev thov dav dav hauv khw tseem xav tau cov txheej txheem thev naus laus zis thiab kev txhawb nqa ntawm cov cai hauv tebchaws.
