Raws li lub ntiaj teb kev txav mus rau kev ruaj khov zuj zus, ntau cov neeg siv khoom thiab cov lag luam tau tig mus rau biodegradable ntim cov kev daws teeb meem. Ntawm lawv, cov yeeb yaj kiab biodegradable tau nthuav dav raws li eco-friendly lwm txoj hauv kev rau cov khoom siv yas. Tab sis ntawm no yog qhov teeb meem: tsis yog tag nrho cov yeeb yaj kiab biodegradable yog cov compostable tiag tiag - thiab qhov sib txawv yog ntau tshaj li cov semantics. To taub dab tsi ua ib zaj duab xiscompostable tiag tiagyog qhov tseem ceeb yog tias koj mob siab rau lub ntiaj teb thiab kev ua raws cai.
Yog li, koj tuaj yeem qhia tau li cas seb koj cov yeeb yaj kiab ntim khoom puas yuav rov qab mus rau qhov xwm txheej lossis nyob hauv qhov chaw pov tseg? Cov lus teb yog nyob rau hauv cov ntawv pov thawj.
Biodegradable vs. Compostable: Qhov txawv tiag tiag yog dab tsi?
Biodegradable Zaj duab xis
Biodegradable zaj duab xiss, zooPLA zaj duab xis, yog tsim los ntawm cov ntaub ntawv uas tuaj yeem tawg los ntawm cov kab mob xws li kab mob los yog fungi. Txawm li cas los xij, cov txheej txheem no tuaj yeem siv sijhawm ntau xyoo thiab tej zaum yuav xav tau ib puag ncig tshwj xeeb xws li cua sov, noo noo, lossis oxygen. Qhov phem tshaj, qee qhov hu ua biodegradable films degrade rau hauv microplastics - tsis yog eco-friendly.
Compostable Zaj duab xis
Compostable films mus ib kauj ruam ntxiv. Lawv tsis tsuas yog biodegrade xwb tab sis yuav tsum ua li ntawd nyob rau hauv composting tej yam kev mob nyob rau hauv ib lub sij hawm tshwj xeeb, feem ntau 90 mus rau 180 hnub. Qhov tseem ceeb tshaj, lawv yuav tsum tawm mustsis muaj tshuaj lom residuethiab tsim tsuas yog dej, carbon dioxide, thiab biomass.
Muaj ob hom loj:
-
Industrially compostable films: Yuav tsum muaj cua sov siab, tswj ib puag ncig.
-
Home compostable films: Ua rau hauv cov khib nyiab khib nyiab hauv qab ntawm qhov kub qis, zoo licellophane zaj duab xis.
Vim li cas Daim Ntawv Pov Thawj Tseem Ceeb?
Txhua tus tuaj yeem nplawm "eco-friendly" lossis "biodegradable" ntawm cov khoom lag luam. Yog vim li cas peb togcompostability ntawv pov thawjtseem ceeb heev - lawv tshawb xyuas tias cov khoom ua tau raws li cov qauv nruj rau ib puag ncig kev nyab xeeb thiab kev ua haujlwm.
Yog tsis muaj ntawv pov thawj, tsis muaj kev lav phib xaub tias zaj duab xis yuav compost raws li tau cog lus tseg. Qhov phem tshaj, cov khoom tsis muaj pov thawj tuaj yeem ua rau cov khoom siv khib nyiab los yog ua rau cov neeg siv khoom tsis zoo.

Kev xav zaum kawg: Daim ntawv pov thawj tsis yog xaiv tau - Nws yog qhov tseem ceeb
Tsis muaj teeb meem li cas biodegradable ib zaj duab xis thov kom ua, tsis muajtxoj cai ntawv pov thawj, nws tsuas yog kev lag luam xwb. Yog tias koj yog lub khw muag khoom ntim khoom ntim - tshwj xeeb tshaj yog rau cov khoom noj, tsim khoom, lossis muag khoom - xaiv cov yeeb yaj kiabtau ntawv pov thawj rau lawv qhov chaw nyob(kev lag luam lossis hauv tsev compost) ua kom muaj kev tswj hwm kev tswj hwm, kev ntseeg siab ntawm cov neeg siv khoom, thiab kev cuam tshuam ib puag ncig tiag.
Xav tau kev pab txheeb xyuas cov ntawv pov thawj PLA lossis cov khoom siv cellophane? Kuv tuaj yeem pab nrog kev taw qhia lossis kev sib piv cov txheej txheem - tsuas yog qhia rau kuv paub!
