Nrog kev txhim kho tas mus li ntawm kev paub txog ib puag ncig, kev lag luam tshuaj pleev ib ce kuj tau coj mus rau hauv kev hloov pauv ntsuab hauv kev ntim khoom. Cov yas ntim khoom siv roj av ib txwm tsis yog tsuas yog siv ntau cov peev txheej thaum lub sijhawm tsim khoom, tab sis kuj ua rau muaj kuab paug rau ib puag ncig thaum lub sijhawm kho tom qab siv. Yog li ntawd, kev tshawb nrhiav cov ntaub ntawv ntim khoom ruaj khov tau dhau los ua qhov teeb meem tseem ceeb hauv kev lag luam tshuaj pleev ib ce.
Cov yas ua los ntawm roj av
Cov yas ua los ntawm roj av yog ib hom yas ua los ntawm cov roj av xws li roj av. Nws muaj cov khoom yas zoo thiab cov khoom siv kho tshuab, yog li nws siv dav hauv ntau qhov chaw. Tshwj xeeb, cov yas ua los ntawm roj av muaj cov hom hauv qab no:
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl chloride (PVC)
Polystyrene (PS)
Polycarbonate (PC)
Cov yas ua los ntawm roj av yog cov khoom siv tseem ceeb hauv kev ntim khoom kom zoo nkauj vim lawv lub teeb yuag, ruaj khov thiab pheej yig. Cov yas ua los ntawm roj av muaj zog thiab tawv dua, tiv taus tshuaj zoo dua thiab ua tau zoo dua li cov yas ib txwm muaj. Txawm li cas los xij, kev tsim cov khoom no xav tau ntau cov peev txheej roj av, ua rau lub ntiaj teb cov peev txheej poob qis. Cov pa roj carbon dioxide uas tsim tawm thaum lub sijhawm tsim khoom siab thiab muaj qee qhov cuam tshuam rau ib puag ncig. Tib lub sijhawm, cov yas ntim khoom feem ntau raug pov tseg tsis raws cai tom qab siv thiab nyuaj rau lwj tom qab nkag mus rau hauv ib puag ncig ntuj, ua rau muaj kev puas tsuaj loj rau av, dej thiab tsiaj qus.
Kev tsim qauv tshiab rau kev ntim khoom ruaj khov
Cov yas rov ua dua tshiab
Cov yas rov ua dua tshiab yog ib hom khoom tshiab uas ua los ntawm cov yas pov tseg los ntawm cov txheej txheem xws li kev tsoo, kev ntxuav, thiab kev sib xyaw. Nws muaj cov yam ntxwv zoo ib yam li cov yas tshiab, tab sis siv cov peev txheej tsawg dua hauv nws cov khoom tsim. Kev siv cov yas rov ua dua tshiab ua cov ntaub ntawv ntim khoom kom zoo nkauj tsis yog tsuas yog txo qhov kev vam khom rau cov peev txheej roj av xwb, tab sis kuj txo cov pa roj carbon thaum lub sijhawm tsim khoom.
Cov khoom siv bioplastics
Bioplastic yog cov yas uas ua los ntawm cov khoom siv biomass (xws li hmoov txhuv nplej siab, cellulose, thiab lwm yam) los ntawm kev fermentation, synthesis thiab lwm yam txheej txheem. Nws muaj cov yam ntxwv zoo ib yam li cov yas ib txwm muaj, tab sis tuaj yeem lwj sai hauv ib puag ncig ntuj thiab zoo rau ib puag ncig. Cov khoom siv raw ntawm bioplastics los ntawm ntau qhov chaw, suav nrog cov quav tsiaj, cov ntoo pov tseg, thiab lwm yam, thiab tuaj yeem rov ua dua tshiab tau zoo heev.
Cov ntaub ntawv ntim khoom siv lwm yam
Ntxiv rau cov yas rov ua dua tshiab thiab cov yas bioplastics, muaj ntau lwm yam khoom siv ntim khoom ruaj khov. Piv txwv li, cov ntaub ntawv ntim ntawv muaj qhov zoo ntawm kev sib dua, rov ua dua tshiab thiab lwj tau, thiab tsim nyog rau kev siv rau hauv cov ntim sab hauv ntawm cov tshuaj pleev ib ce. Txawm hais tias cov ntaub ntawv ntim iav hnyav dua, lawv muaj kev ruaj khov zoo heev thiab rov ua dua tshiab thiab tuaj yeem siv rau kev ntim cov tshuaj pleev ib ce zoo. Tsis tas li ntawd, muaj qee cov ntaub ntawv sib xyaw ua ke tshiab, cov ntaub ntawv sib xyaw ua ke hlau, thiab lwm yam, uas kuj muab ntau txoj kev xaiv rau kev ntim khoom pleev ib ce.
Cov hom lag luam thiab cov neeg siv khoom ua ke ua tiav kev txhim kho kom ruaj khov
Kev ua tiav kev txhim kho kom ruaj khov ntawm cov ntim khoom siv pleev ib ce yuav tsum muaj kev sib koom tes ntawm cov hom lag luam thiab cov neeg siv khoom. Hais txog cov hom lag luam, cov ntaub ntawv ntim khoom ruaj khov thiab cov thev naus laus zis yuav tsum tau tshawb nrhiav thiab siv kom txo qhov cuam tshuam tsis zoo ntawm cov ntim khoom rau ib puag ncig. Tib lub sijhawm, cov hom lag luam kuj tseem yuav tsum txhawb kev kawm txog ib puag ncig rau cov neeg siv khoom thiab coj cov neeg siv khoom kom tsim cov tswv yim siv ntsuab. Cov neeg siv khoom yuav tsum tau them sai sai rau cov ntaub ntawv ntim khoom ntawm cov khoom thiab muab qhov tseem ceeb rau cov khoom uas muaj cov ntim khoom ruaj khov. Thaum siv, qhov ntau ntawm cov ntim khoom siv yuav tsum tau txo kom ntau li ntau tau, thiab cov ntim khoom pov tseg yuav tsum tau cais thiab pov tseg kom raug.
Hauv ntej, kev hloov pauv ntsuab ntawm kev ntim khoom siv pleev ib ce yog ib txoj hauv kev tseem ceeb rau kev lag luam pleev ib ce kom ua tiav kev txhim kho kom ruaj khov. Los ntawm kev siv cov ntaub ntawv ntim khoom thiab cov thev naus laus zis uas ruaj khov thiab txhawb nqa kev kawm txog ib puag ncig, cov hom lag luam thiab cov neeg siv khoom tuaj yeem koom tes pab txhawb rau yav tom ntej ntawm lub ntiaj teb.
