Iipolypropylene nonwovens zisetyenziswa kwiinkalo ezininzi ezifana nokhathalelo lwezonyango, ucoceko, izixhobo zokuzikhusela (PPE), ulwakhiwo, ezolimo, ukupakishwa, kunye nabanye. Nangona kunjalo, ngelixa zibonelela ngobomi babantu, zikwabeka umthwalo omkhulu kwimekobume. Kuqondwa ukuba inkunkuma yayo ithatha amakhulu eminyaka ukubola ngokupheleleyo phantsi kweemeko zendalo, eziye zaba yintlungu kwishishini iminyaka emininzi. Ngokunyuka kolwazi lokukhuselwa kokusingqongileyo kuluntu kunye nokuqhubela phambili kobuchwephesha bemveliso yoshishino, ishishini le-nonwovens lisasaza iimveliso ezizinzileyo kunye nobuchwepheshe ukunciphisa impembelelo kokusingqongileyo.
Ukusukela ngoJulayi 2021, ngokutsho kwe-EU "Umyalelo wokuNcitshiswa kweMpembelelo yokuSingqongileyo yeeMveliso ezithile zePlastiki" (Umyalelo 2019/904), iiplastiki ezingcolisekileyo ze-oxidative ziye zavalwa kwi-EU ngenxa yokuqhekeka kwazo ukuvelisa ungcoliseko lwe-microplastic.
Ukususela nge-1 ka-Agasti 2023, iindawo zokutyela, iivenkile ezithengisayo, kunye namaziko karhulumente e-Taiwan, e-China ayenqatshelwe ukusebenzisa i-tableware eyenziwe nge-polylactic acid (PLA), kuquka iipleyiti, izitya ze-bento, kunye neekomityi. Imodeli yokuthotywa komgquba iye yabuzwa kwaye yakhanyelwa ngamazwe amaninzi kunye nemimandla.
Uzibophelele ekuphefumleni komntu osempilweni kunye nokubonelela ngomoya namanzi acocekileyo,Medlong JOFOiphuhlileIlaphu le-PP elingalukwanga elinokonakala. Emva kokuba amalaphu engcwatywe emhlabeni, ii-microorganisms ezizinikeleyo zibambelela kwaye zenze i-biofilm, zingene kwaye zandise ikhonkco le-polymer yelaphu elingaphothiweyo, kunye nokudala indawo yokuzala ukukhawulezisa ukubola. Kwangaxeshanye, imiqondiso yeekhemikhali ekhutshiweyo itsala ezinye ii-microorganisms ukuba zithathe inxaxheba ekondleni, ziphucula kakhulu ukusebenza kakuhle kokuthotywa. Ivavanywe ngokubhekiselele kwi-ISO15985, ASTM D5511, GB/T 33797-2017 kunye neminye imigangatho, ilaphu le-PP elinokungalukwanga biodegradable linezinga lokuthotywa elingaphezulu kwe-5% phakathi kweentsuku ezingama-45, kwaye ifumene isatifikethi se-Intertek kumbutho ogunyazisiweyo wehlabathi. Xa kuthelekiswa nePP yemveliii-nonwovens eziphothiweyo, I-PP biodegradable nonwovens inokugqiba ukuthotywa kwiminyaka embalwa, ukunciphisa umjikelo we-biodegradation wezinto ze-polypropylene, ezinokubaluleka okulungileyo kukhuseleko lokusingqongileyo.
I-Medlong JOFO amalaphu e-PP angalukwanga anokubola afezekiseke ngokwenene ukuthotywa kwendalo. Kwiimeko ezahlukeneyo zenkunkuma ezinje ngetiphu, elwandle, emanzini ahlaziyekileyo, i-sludge anaerobic, i-anaerobic ephezulu eyomeleleyo, kunye neendawo zendalo zangaphandle, inokonakala ngokupheleleyo kwi-ikholoji kwisithuba seminyaka emi-2 ngaphandle kwetyhefu okanye iintsalela ze-microplastic.
Kwiimeko zokusetyenziswa kwabasebenzisi, inkangeleko yayo, iipropathi zendalo, uzinzo kunye nexesha lokuphila ziyafana namalaphu emveli angalukwanga, kwaye ubomi beshelufu abuchaphazeleki.
Emva kokuba umjikelezo wokusetyenziswa uphelile, unokungena kwinkqubo yokuphinda isetyenziswe kwaye ihlaziywe okanye ihlaziywe ngamaxesha amaninzi, ehlangabezana neemfuno zohlaza, i-carbon-low, kunye nophuhliso lwesetyhula.
