Nyob rau hauv xyoo tas los no, raws li lub ntiaj teb kev paub txog kev tiv thaiv ib puag ncig tau loj hlob, qhov teeb meem ntawm cov pa phem yas tau dhau los ua qhov tseem ceeb. Txhawm rau daws qhov teeb meem no, ntau lub tuam txhab thiab cov chaw tshawb fawb tau tsom mus rau kev txhim khobiodegradable ntim hnab. Cov khoom ntim tshiab no tsis tsuas yog txo qhov cuam tshuam tsis zoo rau ib puag ncig tab sis kuj tseem muaj txoj hauv kev tshiab los daws cov teeb meem kev tswj hwm thoob ntiaj teb.
Dab tsi yog Biodegradable Ntim Hnab?
Biodegradable ntim hnabyog cov ntaub ntawv uas tuaj yeem decompose rau hauv cov khoom tsis zoo xws li carbon dioxide, dej, thiab biomass nyob rau hauv tej yam ntuj tso (xws li tshav ntuj, kub, av noo, thiab microorganisms). Piv nrog rau cov hnab yas ib txwm muaj, qhov zoo tshaj plaws ntawm cov hnab ntim biodegradable yog lawv cov kev cuam tshuam ib puag ncig, txo cov pa phem los ntawm cov chaw pov tseg thiab kev tsim txom.
Kev loj hlob sai hauv kev lag luam xav tau
Raws li cov neeg siv khoom xav tau ntau cov khoom lag luam hauv eco, ntau lub khw muag khoom thiab cov tuam txhab khoom noj tau pib siv cov hnab ntim khoom biodegradable. Cov npe thoob ntiaj teb pom zoo xws li IKEA thiab Starbucks twb tau ua thawj txoj hauv kev los txhawb cov kev daws teeb meem ntawm ib puag ncig zoo. Tib lub sijhawm, ntau lub tseemfwv tau tshaj tawm cov cai los txhawb cov lag luam thiab cov neeg siv khoom siv cov khoom siv biodegradable. Piv txwv li, EU's "Plastic Strategy" tau hais meej meej kom txo qis ntawm cov yas siv ib zaug hauv xyoo tom ntej.
Technological Advances thiab Challenges
Tam sim no, cov khoom siv tseem ceeb rau kev tsim cov hnab ntim khoom biodegradable suav nrog cov khoom siv hmoov txhuv nplej siab, PLA (polylactic acid), thiab PHA (polyhydroxyalkanoates). Txawm li cas los xij, txawm hais tias kev siv thev naus laus zis sai sai, cov hnab ntim biodegradable tseem ntsib qee qhov teeb meem. Ua ntej, lawv cov nqi tsim khoom kuj yog siab heev, txwv tsis pub muaj kev saws loj loj. Qhov thib ob, qee cov khoom lag luam tseem xav tau cov xwm txheej tshwj xeeb rau kev ua kom zoo thiab tsis tuaj yeem degrade tag nrho hauv ib puag ncig zoo tib yam.
Yav tom ntej Outlook
Txawm hais tias muaj kev sib tw thev naus laus zis thiab nqi, lub neej yav tom ntej ntawm biodegradable ntim hnab tseem muaj kev cia siab. Nrog rau kev nqis peev ntau ntxiv hauv kev tshawb fawb thiab kev tsim kho, nrog rau kev nthuav dav ntau lawm, ntim biodegradable yuav tsum ua kom tau txais txiaj ntsig zoo dua. Tsis tas li ntawd, raws li kev cai thoob ntiaj teb ib puag ncig nruj dua, kev siv cov khoom siv biodegradable yuav dhau los ua ib txoj hauv kev tseem ceeb rau cov tuam txhab kom ua tiav lawv cov luag haujlwm hauv zej zog thiab txhim kho lawv cov hom phiaj.
Zuag qhia tag nrho, biodegradable hnab ntim khoom tau maj mam dhau los ua tus neeg tseem ceeb hauv kev ua lag luam rau cov khoom siv yas, tsis yog tsuas yog tsav txoj kev loj hlob ntawm kev tiv thaiv ib puag ncig kev lag luam tab sis kuj pab txhawb kev loj hlob thoob ntiaj teb.
