Ukuzinza kweengxowa zeplastiki ezonakeleyo

Kwiminyaka yakutshanje, umba wongcoliseko lweplastiki utsale ingqwalasela ebanzi kwihlabathi jikelele.Ukujongana nalo mba, iingxowa zeplastiki ezibolisiweyo zithathwa njengenye indlela esebenzayo njengoko zinciphisa iingozi zokusingqongileyo ngexesha lenkqubo yokubola.Nangona kunjalo, ukuzinza kweengxowa zeplastiki ezingonakaliswa ngebhayoloji nako kuphakamise iinkxalabo kunye neempikiswano.

Okokuqala, kufuneka siqonde ukuba yintoni naingxowa yeplastiki eyonakeleyo.Xa kuthelekiswa neengxowa zeplastiki zendabuko, inomsebenzi ophawulekayo, oko kukuthi, inokuchithwa kwiimolekyuli ezincinci phantsi kweemeko ezithile (ezifana nokushisa okuphezulu, umswakama, njl.), Ngaloo ndlela ukunciphisa impembelelo kwindalo.Ezi molekyuli zinokwaphulwa ngakumbi zibe ngamanzi kunye nekharbon diokside kwindawo yendalo.

Iingxowa zeplastiki ezonakeleyo ziyayinciphisa ingxaki yongcoliseko lweplastiki ngexesha lenkqubo yokubola, kodwa kwangaxeshanye, kusekho iingxaki ezithile kumjikelo wabo wobomi.Ukusuka kwimveliso ukuya ekusetyenzisweni ngokutsha kunye nokulahla, kusekho uthotho lwemicelimngeni.

Okokuqala, ukuvelisa iingxowa zeplastiki ezinokubola kufuna amandla amaninzi kunye nezibonelelo.Nangona ezinye izibonelelo ze-bio-based zisetyenziswa kwinkqubo yokuvelisa, kusafuneka kusetyenziswe amanzi amaninzi, umhlaba kunye neekhemikhali.Ukongeza, ukukhutshwa kwekhabhoni ngexesha lemveliso nako kuyinkxalabo.

Okwesibini, ukurisayikilishwa kunye nokulahlwa kweengxowa zeplastiki ezinokonakala ngokwasemzimbeni nako kujongene nobunzima obuthile.Ekubeni iiplastiki ezinokonakala zifuna iimeko ezithile zokusingqongileyo ngexesha lenkqubo yokubola, iintlobo ezahlukeneyo zeengxowa zeplastiki ezinokonakala zinokufuna iindlela ezahlukeneyo zokulahla.Oku kuthetha ukuba ukuba ezi ngxowa zeplastiki zibekwe ngempazamo kwinkunkuma eqhelekileyo okanye zidityaniswe nenkunkuma enokurisayikilishwa, oko kuya kuba nempembelelo embi kuyo yonke inkqubo yokurisayikilishwa nokusetyenzwa kwayo.

Ukongeza, isantya sokubola kweengxowa zeplastiki ezingonakaliswa ngebhayoloji nako kubangele impikiswano.Uphononongo lubonise ukuba ezinye iingxowa zeplastiki ezinokubola zithatha ixesha elide ukubola ngokupheleleyo, kwaye kusenokuthabatha iminyaka.Oku kuthetha ukuba ngeli xesha, zinokubangela ingozi ethile kunye nokungcoliseka kwendalo.

Ukuphendula kwezi ngxaki zingasentla, amanye amashishini kunye namaziko ophando lwezenzululwazi sele eqalisile ukuphuhlisa ezinye iindlela ezilungele ukusingqongileyo.Ngokomzekelo, ezinye izinto ezisekelwe kwi-bio-based, iiplastiki ezivuselelekayo, kunye ne-bioplastics enokonakala ziye zafundwa ngokubanzi kwaye zisetyenziswa.Ezi zinto zintsha zinganciphisa umonakalo kwindalo ngexesha lenkqubo yokubola, kwaye ukukhutshwa kwekhabhoni kwinkqubo yokuvelisa iphantsi.

Ukongeza, urhulumente kunye namashishini oluntu nawo athatha uthotho lwamanyathelo okukhuthaza ukuzinza kweengxowa zeplastiki ezonakeleyo.Amanye amazwe kunye nemimandla baye baqulunqa imimiselo engqongqo yokunciphisa ukusetyenziswa kweengxowa zeplastiki kunye nokukhuthaza ukuphuhliswa nokukhuthazwa kweengxowa zeplastiki ezonakalayo.Kwangaxeshanye, ukulungiselela ukurisayikilishwa kunye nokusetyenzwa kweengxowa zeplastiki ezonakeleyo, kukwayimfuneko ukuqhubela phambili nokuphucula imigaqo-nkqubo efanelekileyo kunye nokuseka inkqubo esele ikhulile yokurisayikilisha nokusetyenzwa kwayo.

Ukuqukumbela, nangona iingxowa zeplastiki ezinokubola zinamandla amakhulu ekunciphiseni ungcoliseko lweplastiki, imiba yazo yokuzinza isafuna ingqalelo eqhubekayo kunye nokuphuculwa.Ngokuphuhlisa ezinye iindlela eziluhlaza, siphucula iinkqubo zokuphinda zisetyenziswe kunye nokulahla, kunye nokomeleza imigaqo-nkqubo nemimiselo, sinokuthatha inyathelo elibalulekileyo ekujonganeni nongcoliseko lweplastiki.
