Peb niaj hnub siv lub ntsej muag lub ntsej muag yog maj mam hloov mus rau qhov tshiab loj ntawm cov pa phem dawb tom qab lub hnab khib nyiab.
Kev tshawb fawb 2020 kwv yees tias 129 billion lub ntsej muag lub ntsej muag tau noj txhua lub hlis, feem ntau yog cov npog ntsej muag uas siv tau los ntawm cov yas microfibers. Nrog rau COVID-19 kis thoob qhov txhia chaw, lub qhov ncauj qhov ntswg pov tseg tau tshaj tawm hauv ntau lub tebchaws los tiv thaiv COVID-19 vim tias lawv tuaj yeem pab tiv thaiv kev sib kis ntawm COVID-19 thiab lwm yam kab mob, ua rau cov ntaub ntawv no hloov kho tas li.
Txawm li cas los xij, nyob rau hauv qhov xwm txheej ntawm kev siv siab, tsis muaj lub teb chaws tau ua "kev cai" cov txheej txheem rov ua dua tshiab rau lub qhov ncauj qhov ntswg, uas ua rau muaj kev pov tseg ntau dua ntawm cov khoom siv pov tseg no ua cov khoom pov tseg, uas ua rau muaj kev sib tw ntau dua rau kev tswj hwm cov pa phem thoob ntiaj teb.
Nrhiav kom muaj kev daws teeb meem zoo rau ntiaj teb cov teeb meem yas muaj kuab paug los ntawm qhov ncauj qhov ntswg pov tseg yog qhov tseem ceeb.
Tsis ntev los no, ob tus kws tshawb fawb txog biotechnology los ntawm Gazamada University tau thov tias cov ntaub ntawv npog qhov ncauj qhov ntswg yuav raug muab pov tseg nrog biodegradable pov tseg qhov ncauj qhov ntswg ua los ntawm pineapple nplooj.
Lub npog ntsej muag biodegradable feem ntau yog ua los ntawm fibers los ntawm pineapple nplooj, thiab vim hais tias lawv siv tej yam ntuj tso fibers es tsis txhob ntawm yas fibers, microorganisms xws li fungi los yog kab mob tuaj yeem pib cov txheej txheem degradation sai dua tom qab immersion hauv av (cia siab tias yuav siv peb hnub).

Nws tau nkag siab tias pineapple muaj ntau heev nyob rau hauv cov cheeb tsam sov, cov ntaub ntawv tseem ceeb qhia tau hais tias lub ntiaj teb no pineapple ntau lawm mus txog 27.82 lab tons nyob rau hauv 2020. Pineapple nplooj muaj ib tug ntawm lub siab tshaj plaws paub tej yam ntuj tso fibers nyob rau hauv fiber ntau (ze li 80%), thiab muaj. Muaj ntau txoj hauv kev los rho tawm cov fiber ntau los ntawm pineapple nplooj, ua pineapple nplooj fiber ntau suav tias yog lwm txoj hauv kev zoo rau cov yas fiber ntau los ntawm cov kws tshawb fawb biotechnology.
Daim duab | Ntiaj teb ua lag luam nyob rau hauv pineapple ntau lawm nyob rau hauv 2020, uas lub Philippines, Costa Rica thiab Brazil yog lub ntiaj teb no peb loj tshaj plaws pineapple producers (qhov chaw: Statista).
Pineapple nplooj fibers yog xim dawb, muaj lub ntsej muag ci, muaj lub zog tensile siab, muaj qhov zoo nkauj zoo nkauj dua li lwm cov nroj tsuag fibers (xws li hemp, jute, flax, thiab canna), thiab yooj yim rau stain. Pineapple nplooj fibers yog teem nyob rau hauv tib txoj kev raws li paj rwb, tab sis lawv yog ib puag ncig zoo dua li paj rwb.
Paj rwb yog ib txwm cog nrog tshuaj tua kab thiab chiv, thiab yog tsim los ntawm cov tshuaj hnyav, qee qhov tseem nyob thiab tsis tuaj yeem ntxuav tawm. Pineapple nplooj, ntawm qhov tod tes, yog loj hlob yam tsis muaj tshuaj ntxiv thiab tuaj yeem rov tsim dua txhua xyoo thiab tau yooj yim tau.
Tam sim no, ntau cov nplooj pineapple tau tsim txhua xyoo, tshwj tsis yog qee qhov me me uas ua rau pineapple nplooj fiber ntau thiab siv rau hauv cov khoom siv raw thiab lub zog tsim khoom (xws li ua hlua, twine, cov khoom sib xyaw thiab cov khoom siv khaub ncaws). Feem ntau muab pov tseg raws li kev ua liaj ua teb pov tseg, kev siv cov pineapple nplooj yuav tsis tsuas yog txo cov pa phem ib puag ncig, tab sis kuj coj qee cov txiaj ntsig kev lag luam.
Qhov ncauj qhov ntswg biodegradable tseem ceeb npaum li cas rau tib neeg? Ib daim npog ntsej muag uas siv tau pov tseg muaj peb txheej ntawm polymer. Cov txheej txheej sab nrauv yog cov khoom tsis nqus dej (xws li polyester), cov txheej nruab nrab yog cov ntaub tsis-woven (xws li polypropylene thiab polystyrene) ua los ntawm cov txheej txheem yaj-tshuab, thiab txheej txheej sab hauv yog cov khoom nqus dej xws li paj rwb. . Polypropylene, cov khoom siv feem ntau siv hauv kev tsim daim npog ntsej muag, yog qhov nyuaj heev los rhuav tshem nws tuaj yeem nyob hauv ib puag ncig ecological tau ntau xyoo, thiab tej zaum ntau pua xyoo, tig mus rau hauv microplastics thiab nanoplastics.
Ntxiv rau qhov ua rau muaj kab mob hauv cov yas, cov qhov ncauj qhov ntswg pov tseg tseem tuaj yeem sib sau thiab tso tawm cov tshuaj phem thiab cov tshuaj lom neeg, xws li Bisphenol A (BPA), cov hlau hnyav, thiab cov kab mob kab mob. Ntawm lawv, bisphenol A tau taw qhia tias muaj cov nyhuv carcinogenic.
Tsis tas li ntawd, lwm cov kev tshawb fawb tau pom tias lub qhov ncauj qhov ntswg tuaj yeem raug thauj los ntawm av mus rau cov dej qab zib thiab Marine ib puag ncig los ntawm cov dej ntws, dej ntws, dej hiav txwv, cua, thiab tsiaj txhu (los ntawm kev sib txuas lossis kev noj haus) yog tias tsis tau sau thiab tswj kom zoo. Raws li tsab ntawv tshaj tawm xyoo 2020 los ntawm OceansAsia, "Kev kwv yees li 1.56 billion lub ntsej muag lub ntsej muag yuav nkag mus rau hauv dej hiav txwv xyoo 2020, ua rau muaj 4,680 txog 6,240 tons ntawm Marine cov pa phem ntxiv."

Nws tuaj yeem hais tias nrog kev txhim kho ib txwm muaj kev sib kis, cov pov tseg ntawm lub qhov ncauj qhov ntswg tsuas yog sib sau ntau thiab ntau dua, thiab cov pa phem rau ib puag ncig ecological yuav tsuas yog loj dua thiab ntau dua. Cov qhov ncauj qhov ntswg pov tseg ua los ntawm pineapple nplooj fibers, uas degrade ib txwm thiab tsis tso cov co toxins, yuav yog ib qho kev daws teeb meem rau cov pa phem los ntawm lub qhov ncauj qhov ntswg.
Txawm li cas los xij, vim muaj qhov dej ntawm cov pineapple nplooj fiber ntau, nws tsis muaj zog thiab ruaj khov li yas. Xav tau kev tshawb fawb ntxiv los daws qhov teeb meem no.
