Nrog rau kev txhim kho txuas ntxiv 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 ntim. Kev siv roj av-raws li cov yas ntim khoom siv tsis tsuas yog siv ntau cov peev txheej thaum lub sijhawm tsim khoom, tab sis kuj ua rau muaj kuab paug ib puag ncig hnyav thaum siv tom qab siv. Yog li ntawd, kev tshawb nrhiav cov khoom ntim ruaj khov tau dhau los ua qhov teeb meem tseem ceeb hauv kev lag luam tshuaj pleev ib ce.
Petroleum-based plastics
Petroleum-based plastics yog ib hom khoom siv yas ua los ntawm fossil fuels xws li roj av. Nws muaj zoo plasticity thiab mechanical zog, yog li nws yog dav siv nyob rau hauv ntau yam teb. Tshwj xeeb, roj av-raws li plastics suav nrog cov hauv qab no:
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl chloride (PVC)
Polystyrene (PS)
Polycarbonate (PC)
Petroleum-based plastics dominated cosmetic ntim vim lawv lub teeb yuag, durability thiab nqi-zoo. Petroleum-based plastics muaj zog dua thiab hardness, zoo tshuaj tiv thaiv thiab ua tau zoo dua li cov yas yas. Txawm li cas los xij, kev tsim cov khoom siv no xav tau ntau cov peev txheej roj av, ua rau lub ntiaj teb cov peev txheej ntau dhau. Lub CO2 emissions uas tsim thaum lub sij hawm nws cov txheej txheem ntau lawm yog siab thiab muaj tej yam cuam tshuam rau ib puag ncig. Nyob rau tib lub sijhawm, cov ntim yas feem ntau muab pov tseg tom qab siv tas li thiab nyuaj rau degrade tom qab nkag mus rau hauv ib puag ncig ntuj, ua rau muaj kev puas tsuaj loj rau cov av, dej thiab tsiaj qus.
Lub tswv yim tsim kev daws teeb meem rau kev ntim khoom ruaj khov
Recycled yas
Cov yas rov ua dua tshiab yog ib yam tshiab ntawm cov khoom siv pov tseg los ntawm cov txheej txheem xws li crushing, tu, thiab smelting. Nws muaj cov khoom zoo sib xws rau cov yas yas, tab sis siv tsawg dua cov peev txheej hauv nws cov khoom. Kev siv cov yas rov ua dua tshiab raws li cov ntaub ntawv ntim tshuaj pleev ib ce tuaj yeem tsis tsuas yog txo cov kev cia siab ntawm cov khoom siv roj av, tab sis kuj txo cov pa roj carbon emissions thaum lub sijhawm tsim khoom.
Bioplastics
Bioplastic yog cov khoom siv yas ua tiav los ntawm cov khoom siv biomass (xws li cov hmoov txhuv nplej siab, cellulose, thiab lwm yam) los ntawm cov khoom siv roj ntsha, kev sib txuas thiab lwm yam txheej txheem. Nws muaj cov khoom zoo sib xws rau cov khoom siv yas, tab sis tuaj yeem degrade sai sai hauv ib puag ncig ntuj thiab yog ib puag ncig zoo. Cov ntaub ntawv raw ntawm bioplastics yog los ntawm ntau qhov chaw, nrog rau cov qoob loo straws, ntoo khib nyiab, thiab lwm yam, thiab muaj peev xwm rov ua dua tshiab.
Lwm cov khoom ntim khoom
Ntxiv nrog rau cov khoom siv rov ua dua tshiab thiab cov khoom siv bioplastics, muaj ntau lwm cov ntaub ntawv ntim khoom ruaj khov. Piv txwv li, cov ntaub ntawv ntim cov ntawv muaj qhov zoo ntawm kev sib sib zog nqus, rov ua dua thiab degradable, thiab tsim nyog siv rau hauv ntim cov khoom pleev xim sab hauv. Txawm hais tias cov iav ntim cov ntaub ntawv hnyav dua, lawv muaj cov kav ntev thiab rov ua dua tshiab thiab tuaj yeem siv rau ntim cov tshuaj pleev ib ce high-end. Tsis tas li ntawd, muaj qee qhov tshiab bio-based composite cov ntaub ntawv, cov khoom siv hlau sib xyaw, thiab lwm yam, uas tseem muaj ntau txoj kev xaiv rau kev ntim khoom kom zoo nkauj.
Cov khoom lag luam thiab cov neeg siv khoom sib koom ua tiav kev txhim kho kom ruaj khov
Kev ua tiav kev tsim kho kom ruaj khov ntawm kev ntim tshuaj pleev ib ce yuav tsum muaj kev sib koom ua ke ntawm cov khoom 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 los txo qhov tsis zoo ntawm kev ntim khoom rau ib puag ncig. Nyob rau tib lub sijhawm, cov khoom lag luam yuav tsum ntxiv dag zog rau ib puag ncig kev kawm rau cov neeg siv khoom thiab qhia cov neeg siv khoom tsim cov tswv yim ntsuab noj. Cov neeg siv khoom yuav tsum xyuam xim rau cov khoom ntim khoom ntawm cov khoom thiab muab qhov tseem ceeb rau cov khoom lag luam nrog kev ntim khoom ruaj khov. Thaum siv, cov ntim ntim siv yuav tsum raug txo kom ntau li ntau tau, thiab cov ntim khib nyiab yuav tsum tau muab faib thiab muab pov tseg kom raug.
Nyob rau hauv luv luv, lub kiv puag ncig ntsuab ntawm cov tshuaj pleev ib ce ntim yog ib txoj hauv kev tseem ceeb rau kev lag luam tshuaj pleev ib ce kom ua tiav txoj kev loj hlob. Los ntawm kev siv cov khoom ntim khoom ruaj khov thiab thev naus laus zis thiab ntxiv dag zog rau kev kawm ib puag ncig, cov khoom lag luam thiab cov neeg siv khoom tuaj yeem koom ua ke rau lub ntiaj teb yav tom ntej.
