Ukungcoliswa kwepulasitiki kubangela usongo olukhulu endaweni yethu ezungezile, ngamathani angaphezu kwezigidi eziyizinkulungwane ezingu-9 epulasitiki akhiqizwa kusukela ngawo-1950, kanye namathani amangalisayo ayizigidi ezingu-8.3 aphelela olwandle lwethu minyaka yonke.Ngaphandle kwemizamo yomhlaba wonke, u-9% kuphela wepulasitiki osetshenziswa kabusha, okushiya iningi lingcolise i-ecosystem yethu noma lihlale ezindaweni zokulahla imfucuza amakhulu eminyaka.
Okunye okuba nomthelela omkhulu kule nkinga wukudlanga kwezinto zepulasitiki ezisetshenziswa kanye njengezikhwama zepulasitiki.Lezi zikhwama, ezisetshenziselwa isilinganiso semizuzu eyi-12 nje, ziqhubekisela phambili ukuthembela kwethu kumapulasitiki alahlwayo.Inqubo yabo yokubola ingathatha iminyaka engaphezu kwengu-500, ikhiphe ama-microplastic ayingozi emvelweni.
Nokho, phakathi kwalezi zinselele, amapulasitiki angaboli anikeza isixazululo esithembisayo.Eyenziwe ngezinto ezivuselelekayo ezingamaphesenti angama-20 noma ngaphezulu, amapulasitiki ezinto eziphilayo anikeza ithuba lokunciphisa ukuthembela kwethu emafutheni ezinto ezimbiwa phansi futhi anciphise indawo yethu yekhabhoni.I-PLA, etholakala emithonjeni yezitshalo efana nesitashi sombila, kanye ne-PHA, ekhiqizwa amagciwane, ziyizinhlobo ezimbili eziyinhloko zamapulasitiki ezinto eziphilayo asebenza ngezindlela ezihlukahlukene.
Nakuba amapulasitiki abolayo enikeza enye indlela eco-friendly, kubalulekile ukucabangela imiphumela yawo engemihle yokukhiqiza.Ukucubungula amakhemikhali kanye nezinqubo zezolimo ezihlotshaniswa nokukhiqizwa kwe-bioplastic kungaba nomthelela ekungcoliseni nasekusetshenzisweni komhlaba.Ukwengeza, ingqalasizinda efanele yokulahla i-bio-plastiki isalokhu ilinganiselwe, okugqamisa isidingo samasu aphelele okulawula imfucuza.
Ngakolunye uhlangothi, amapulasitiki angasebenza kabusha anikeza isixazululo esicindezelayo esisebenza ngempumelelo efakazelwe.Ngokugqugquzela ukugaywa kabusha kanye nokutshala imali engqalasizinda ukuze siyisekele, singaphambukisa udoti wepulasitiki ezindaweni zokulahla imfucumfucu futhi sinciphise umthelela wethu kwezemvelo.Nakuba amapulasitiki abolayo ebonisa isithembiso, ukushintshela emnothweni oyindilinga, lapho izinto ezisetshenziswayo ziphinde zisetshenziswe futhi zigaywe kabusha, zinganikeza isixazululo esimeme kakhudlwana sesikhathi eside enkingeni yokungcoliswa kwepulasitiki.
