Imiququ enokubola esele isetyenziswa kwiindawo ezininzi zokutya ezinkulu endaweni yeendiza zeplastiki.Ukukhuthazwa kunye nokusetyenziswa kweendiza ezinobomi obuphilayo kunokubaluleka okubalulekileyo.Okwangoku, abantu baqhelene neendiza, ezisetyenziswa kumashishini amaninzi ahlukeneyo okutya.Ngenxa yokuba izitro zeplastiki zixhomekeke kwiingxaki ezithile zokusingqongileyo kunye nokuchithwa kwemithombo yobutyebi, zixhalabisa kakhulu kuwo onke amacandelo.Enyanisweni, iindiza zephepha kunyeiindiza ezinokubola zombini zihambelana nokusingqongileyo kwindalo, kodwa iindiza zephepha zilula ukuthambisa iziselo ezishushu kunyeiindiza ezinokubolaziluncedo ngakumbi.

Okwangoku, enye imathiriyeli ehambelana nokusingqongileyo yengca yeplastiki ibizwa ngokuba yi-PLA, okanye “i-polylactic acid”.Yiplastiki ebolisekayo enokutsalwa kwisitatshi sombona.I-PLA iveliswa kwi-asidi ye-lactic, eyimathiriyeli ekrwada kuninzi lwesintu lwe-lactic acid fermentation, kwaye isetyenziselwa ukuvelisa i-PLA.Inkqubo yemveliso ethile kukutyumza umbona, ukukhupha istatshi kuyo, emva koko wenze isitashi esingacocwanga kwisitatshi, emva koko uvundise iswekile ngendlela efana nokuveliswa kotywala, kwaye emva kokuba isitashi sivundisiwe, iba yi-lactic acid efana nayo. i-additive food, kunye ne-lactic acid iguqulwa ibe yimveliso ephakathi yinkqubo ekhethekileyo yoxinaniso kumntu ngamnye we-lactic acid.

I-PLAiindiza ezinokubolaube ne-biodegradability elungileyo, ukuthotywa kuvelisa i-CO2 kunye ne-H2O, akukho ngcoliseko kwendalo, kwaye inokwanelisa iimfuno zokwenziwa komgquba kwimizi-mveliso.Emva kokugqithiswa kobushushu obuphezulu, i-straw inokumelana nobushushu obuhle, ukuchasana kakuhle kwe-solvent, kunye nokuguda kwayo, ukuhanjiswa kokukhanya, kunye neempawu zokuziva zezandla zinokuthatha indawo yeemveliso ezisekelwe kwipetroleum, kunye nezalathi ezibonakalayo kunye neekhemikhali zeemveliso zinokuhlangabezana neemfuno zokhuseleko lokutya. kumhlaba jikelele.Ngoko ke, isetyenziswa ngokubanzi kwaye iyakwazi ukuziqhelanisa neemfuno zezona ziselo ezininzi kwimarike yangoku.

Njengempahla yesiselo sephepha leendiza, ezisetyenziswa kushishino lokutya kunye nemveliso yesiselo sempilo yemveliso yemizi-mveliso, ukukwazi ukuyibuyisela ngokupheleleyo, uluhlu lwesicelo sokuqala seplastiki, kunye nabavelisi bobugcisa bokulungisa ityhubhu yephepha ngokwemimiselo eyahlukeneyo yabathengi, abavelisi banoku ngokusekwe kumalungiselelo akhethekileyo omntu wonke ukwenza izisombululo zoyilo kunye nemveliso kunye nokusetyenzwa.Ngoko ke, kungekhona ubude kunye nobubanzi bomququ kuphela, kodwa kunye nombala kunye noyilo lwepateni, zonke ezo zinokuthi ziyilwe kwaye zisonjululwe.
