Tsawg-density polyethylene (LDPE) yog tam sim no feem ntau siv cov txheej txheem txheej txheej rau daim ntawv.Polylactic acid (PLA) yog qhov thib ob rau nws, suav txog ntau dua 5% ntawm kev lag luam sib koom hauv kev lag luam, uas yog qhov kev txhim kho zoo heev rau 5 xyoo dhau los.Txawm li cas los xij, tsis ntev los no kev tshawb fawb thiab kev tshawb fawb txog bioplastics tau teeb tsa kev tshawb nrhiav tus ntsuj plig tshaj qhov kev txhawb nqa ntawm PLA thiab polybutylene adipate terephthalate (PBAT).Cov kev tshawb pom tshiab kuj tau cuam tshuam rau nws daim ntawv thov hauv cov khoom siv pov tseg.
Thaum Lub Rau Hli 29th 2023, Environmental Protection Administration (EPA) hauv Taiwan, tshaj tawm kev txwv tsis pub siv cov tais diav ua los ntawm PLA, ntawm cov khw noj mov, khw muag khoom thiab cov chaw ua haujlwm pej xeem uas tau pib siv thaum Lub Yim Hli 1, 2023.
Nyob rau lub sijhawm no, kev txhim kho ntawm cov khoom siv bio-based tshiab vam meej.Siv PHA ua piv txwv.Niaj hnub no, nws tau tawm tsam nws txoj hauv kev mus rau theem tsim khoom txawm tias xyoo 'kev kawm txog lub tswv yim thiab kev sim kuaj.Xyoo tas los, thawj qhov haujlwm ntawm Bluepha™️ hauv Yancheng ntawm Jiangsu tau pib ua haujlwm nrog kev tsim tawm txhua xyoo ntawm 5,000 tonnes.Nws yog ib qho tseem ceeb uas nws cov phiaj xwm thib ob thiab thib peb twb nyob rau hauv txoj kev nrog lub peev xwm ntawm kaum tawm txhiab tons rau marine degradable biopolymer.
Tsav los ntawm qhov kev thov los ntawm cov neeg siv khoom siv ntawv, qhov xav tau los tsim cov txheej txheem dej raws li qhov cuam tshuam tsis zoo tau tuaj rau pem hauv ntej.Daim ntawv thiab lub rooj tsavxwm yog tus yam ntxwv raws li cov khoom ntim khoom degradable.Dispersion barrier coatings raws li kev daws teeb meem los txo nws txoj kev cia siab rau cov txheej txheem yas rau cov khoom thaiv cov khoom muaj kev sib tw thiab kev cog lus.Txawm li cas los xij, lub neej yav tom ntej ntawm cov khoom lag luam muaj txiaj ntsig yuav xav tau kev nqis peev ntxiv thiab kev tshawb fawb los ntawm kev lag luam rau cov khoom lag luam innovation thiab kev kho dua tshiab.
