Txoj kev loj hlob ntawm cov hnab yas biodegradable yog qhia txog qhov zoo, feem ntau cuam tshuam los ntawm ntau yam xws li kev cai ib puag ncig, kev vam meej, kev lag luam xav tau kev loj hlob, thiab kev paub txog ib puag ncig ntawm cov neeg siv khoom. Cov hauv qab no yog cov ncauj lus kom ntxaws txog kev txhim kho ntawm cov hnab yas biodegradable:
1, Txoj cai nce qib
Ntiaj teb txoj cai ib puag ncig: Ntau lub teb chaws thiab cheeb tsam thoob ntiaj teb tau tshaj tawm txoj cai ntsuas kev txwv tsis pub siv cov yas yas thiab txhawb nqa biodegradable plastics, muab txoj cai kev txhawb nqa thiab kev lag luam xav tau rau kev tsim cov hnab yas biodegradable.
Piv txwv li, cov teb chaws tsim kho thiab thaj chaw xws li European Union, Tebchaws Meskas, thiab Nyij Pooj twb tau los yog tam sim no tsim cov cai tswj kev ua phem rau cov yas los txhawb kev siv cov yas biodegradable.
Tuam Tshoj txoj cai ib puag ncig: Nyob rau xyoo tas los no, tsoomfwv Suav tau qhia kev txiav txim siab ruaj khov thiab ua haujlwm hauv kev tiv thaiv ib puag ncig. Nyob rau hauv teb rau ib puag ncig muaj kuab paug los ntawm cov tsoos hnab yas, ib tug series ntawm txoj cai tau raug qhia los txhawb kev noj qab haus huv txoj kev loj hlob ntawm biodegradable hnab yas ua lag luam.
Xws li "Cov Kev Xav Txog Kev Txhim Kho Cov Plastic Pollution Control Ntxiv", "Plastic Ban Order", "Dual Carbon" txoj cai, thiab lwm yam, cov kev cai no tsis tsuas yog txwv cov txheej txheem ntau lawm thiab cov peev txheej ntawm cov hnab yas ib txwm muaj, tab sis kuj qhia cov lag luam kom nce ntxiv. lawv cov kev tshawb fawb thiab kev tsim kho kev siv tshuab biodegradable yas los ntawm qhov chaw, txhawb kev tsim khoom thiab nrov ntawm cov hnab yas zoo ib puag ncig.
2, Kev kawm txuj ci
Cov ntaub ntawv tshawb fawb thiab kev tsim kho: Nrog rau kev txhim kho txuas ntxiv ntawm cov ntaub ntawv tshawb fawb, kev kawm tseem ceeb tau ua tiav hauv kev tshawb fawb thiab tsim cov khoom siv yas tshiab biodegradable. Piv txwv li, biodegradable plastics xws li PLA (polylactic acid) thiab PBAT (polyethylene terephthalate adipic acid butanediol ester) tau nyiam heev vim lawv cov khoom zoo heev, biocompatibility, thiab degradability. Cov ntaub ntawv no maj mam nce mus rau cov khoom siv yas raws li kev ua tau zoo thaum tswj kev ua haujlwm zoo ib puag ncig, muab kev txhawb zog rau kev siv cov hnab yas biodegradable.
Cov txheej txheem ntau lawm: Kev txhim kho tas mus li ntawm cov txheej txheem ntau lawm kuj tau txhawb kev tsim cov hnab yas biodegradable. Los ntawm optimizing cov txheej txheem ntau lawm thiab degradation technologies, lub durability, load-bearing muaj peev xwm, thiab degradation kev ua tau zoo ntawm biodegradable hnab yas tuaj yeem txhim kho kom tau raws li kev xav tau ntawm kev ua lag luam.
3, Kev lag luam xav tau kev loj hlob
Cov neeg siv khoom xav tau: Nrog kev txhim kho ntawm cov neeg siv khoom ib puag ncig kev paub, kev lees paub ntawm cov khoom zoo ib puag ncig txuas ntxiv nce ntxiv. Cov hnab yas degradable, raws li cov khoom lag luam ua los ntawm cov ntaub ntawv zoo ib puag ncig, tau maj mam tau txais kev nyiam ntawm cov neeg siv khoom. Tshwj xeeb tshaj yog nyob rau hauv cov khw muag khoom, zaub mov, tshuaj, kev ua liaj ua teb, thiab kev thauj mus los, cov kev lag luam no muaj cov kev xav tau siab rau kev tiv thaiv ib puag ncig thiab kev tsim kho kom ruaj khov, uas yuav txhawb nqa kev siv cov hnab yas biodegradable.
Kev lag luam loj: Raws li kev tshawb fawb kev lag luam, ob lub ntiaj teb thiab Suav biodegradable hnab yas kev lag luam tau qhia txog kev loj hlob tseem ceeb. Nws cia siab tias nyob rau hauv ob peb xyoos tom ntej no, nrog rau kev txhawb nqa txuas ntxiv ntawm cov cai thiab kev nce qib ntawm kev siv thev naus laus zis, kev lag luam loj yuav nthuav dav ntxiv.
4, Kev sib koom ua ke thiab kev ua kom zoo ntawm cov saw hlau
Kev txhim kho kev lag luam: Lub hnab yas biodegradable kev lag luam saw npog ntau yam kev sib txuas xws li kev tshawb fawb thiab kev tsim khoom raw, kev tsim khoom thiab kev tsim khoom, kev muag khoom, thiab kev pov tseg pov tseg. Nrog rau kev txhim kho tas mus li ntawm kev ua lag luam, cov saw hlau ua lag luam yuav raug txhim kho ntxiv thiab ua kom zoo dua qub.
Kev koom tes ntawm cov lag luam sab saud thiab qis qis yuav dhau los ua ze dua, sib koom ua ke txhawb txoj kev loj hlob ntawm biodegradable hnab yas kev lag luam.
Standardization thiab normalization: Yuav kom tswj txoj kev loj hlob ntawm biodegradable plastics kev lag luam, lub teb chaws tau tsim ib tug series ntawm cov qauv thiab specifications. Kev siv cov qauv no thiab cov lus qhia tshwj xeeb yuav txhawb nqa kev siv dav dav ntawm biodegradable plastics hauv ntau qhov chaw thiab tsav kev noj qab haus huv ntawm kev lag luam.
5, Kev cia siab yav tom ntej
Kev tsim kho thev naus laus zis: Kev tsim kho thev naus laus zis yuav yog qhov tseem ceeb hauv kev txhawb nqa txoj kev loj hlob ntawm biodegradable hnab yas kev lag luam. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm cov ntaub ntawv tshawb fawb, cov txheej txheem tsim khoom, thiab cov thev naus laus zis degradation, kev ua haujlwm ntawm cov hnab yas biodegradable yuav raug txhim kho ntxiv thiab cov nqi yuav raug txo ntxiv.
Kev nthuav dav kev lag luam: Cov chaw siv cov hnab yas biodegradable yuav nthuav dav ntxiv thiab tob zuj zus. Ntxiv rau qhov chaw ntim khoom ib txwm siv, nws tseem yuav siv dav hauv kev ua liaj ua teb, kev kho mob, kev tsim kho thiab lwm yam.
Txuas ntxiv kev txhawb nqa ntawm ib puag ncig cov cai: Ib puag ncig cov cai yuav txuas ntxiv muab kev lees paub muaj zog rau kev txhim kho ntawm biodegradable hnab yas kev lag luam. Nrog rau kev txhim kho tas mus li thoob ntiaj teb kev paub txog ib puag ncig thiab kev txhawb nqa txuas ntxiv ntawm cov cai, cov hnab yas biodegradable yuav dhau los ua ib qho ntawm cov khoom lag luam tseem ceeb hauv khw hnab yas yav tom ntej.
Txoj kev loj hlob ntawm cov hnab yas biodegradable yog qhia txog qhov zoo. Raws li kev sib koom ua ke ntawm kev txhawb nqa txoj cai, kev ua haujlwm thev naus laus zis, kev lag luam xav tau kev loj hlob, thiab kev lag luam kev sib koom ua ke thiab kev ua kom zoo, kev lag luam hnab yas biodegradable yuav ua rau muaj kev loj hlob dav dav.
