Lub neej txee ntawm Compostable khob yog dab tsi?
Kev nce hauv cov koob npe ntawm cov khob compostable tau muab rau cov neeg siv khoom muaj txiaj ntsig zoo rau cov khoom siv ib zaug. Cov khob no yog tsim los kom degrade nyob rau hauv ib puag ncig tswj composting, hloov mus rau hauv nplua nuj organic teeb meem. Txawm li cas los xij, lub neej txee ntawm cov khob compostable yog qhov tseem ceeb rau lawv txoj kev siv tau zoo thiab kev cuam tshuam ib puag ncig. Hauv tsab xov xwm no, peb tshawb txog lub neej txee ntawm cov khob compostable thiab qhov tseem ceeb ntawm kev pov tseg raws sij hawm.
Compostable khob yog tsim los ntawm cov ntaub ntawv uas tawg nyob rau hauv tej yam kev mob, feem ntau los ntawm ib tug tswj composting txheej txheem. Cov khob yog tsim los kav ntev rau ib lub sijhawm ua ntej lawv pib degrade. Lub sijhawm no yog lub npe hu ua lub txee lub neej ntawm lub khob.
Lub neej txee ntawm cov khob compostable tuaj yeem sib txawv nyob ntawm cov khoom siv hauv lawv cov khoom. Qee lub khob yog tsim los ntawm cov khoom siv cog qoob loo, xws li ntawv lossis bioplastics, uas muaj lub neej txee luv dua vim lawv qhov muaj pes tsawg leeg. Cov khob no feem ntau degrade nyob rau hauv ob peb lub lis piam mus rau ob peb lub hlis thaum raug rau tej yam kev mob tsim nyog.
Lwm cov khob compostable yog tsim los ntawm cov khoom siv ruaj khov dua, xws li glassine lossis biobased polymers, uas muaj lub neej txee ntev dua. Cov khob no yuav kav ntev li ob peb xyoos ua ntej lawv pib degrade. Txawm li cas los xij, txawm tias cov khob no thaum kawg yuav degrade yog tias raug rau cov xwm txheej zoo.
Nws yog ib qho tseem ceeb kom pov tseg cov khob compostable hauv lawv lub txee lub neej kom ntseeg tau tias muaj txiaj ntsig zoo. Yog tias lub khob tau tso tseg ntev dhau ua ntej muab pov tseg, lawv tuaj yeem pib degrade ntxov ntxov, txo lawv cov qauv kev ncaj ncees thiab ua rau lawv muaj feem cuam tshuam los yog nchuav. Qhov no tuaj yeem ua rau muaj kuab paug ib puag ncig thiab tsim cov khoom pov tseg ntxiv.
Txhawm rau kom muaj txiaj ntsig zoo ib puag ncig ntawm cov khob ntim dej, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov lus pom zoo muab pov tseg los ntawm cov chaw tsim khoom lossis chaw tsim khoom. Cov lus qhia no feem ntau pom zoo kom muab cov khob pov tseg rau hauv lawv lub txee lub neej thiab xyuas kom lawv tsis txhob raug kub hnyiab, UV teeb, lossis lwm yam xwm txheej uas tuaj yeem ua kom tawg.
Hauv kev xaus, kev nkag siab txog lub neej txee ntawm cov khob compostable yog qhov tseem ceeb rau kev ua tiav lawv cov txiaj ntsig kev ruaj ntseg ib puag ncig. Kev pov tseg raws sij hawm kom ntseeg tau tias lub khob degrade zoo thiab tsis txhob muaj kev puas tsuaj ntxov ntxov, txo cov peev txheej ntawm ib puag ncig. Kev pov tseg kom raug kuj txhawb kev lag luam ncig los ntawm kev khaws cov khob hauv lub voj voog kom ruaj khov rau lub sijhawm ntev. Raws li cov neeg siv khoom paub ntau ntxiv txog qhov tseem ceeb ntawm kev pov tseg raws sij hawm, lawv tuaj yeem ua kom paub ntau ntxiv txog lawv cov kev hloov pauv hloov mus rau ib leeg-siv plastics.
