Ukukhathazeka okukhulayo kwezemvelo okuhlotshaniswa namapulasitiki avamile kuqhuba ukuthuthukiswa kanye nokwamukelwa okukhulu kwamapulasitiki angaboli.Lawa ma-bioplastics aklanyelwe ukuhlukana abe yizinhlanganisela ezingenabungozi ngaphansi kwezimo ezithile, ezithembisa ukunciphisa ukungcoliswa kwepulasitiki.Kodwa-ke, njengoba ukusetshenziswa kwamapulasitiki abolayo kwanda kakhulu, kuvela isethi entsha yezinselelo nezinkinga.
Kulesi sihloko, sinikeza isifundo esijulile sezinkinga ezihlobene nazoamapulasitiki angaboli, ekhanyisa isidingo sendlela edidiyelwe yokubhekana nazo ngempumelelo.Izimangalo ezidukisayo kanye nemibono eyiphutha yabathengi: Inkinga enkulu ngamapulasitiki abolayo ilele ezimangalweni ezidukisayo zabathengi kanye nokungaqondi kahle mayelana nethemu."i-biodegradable."Abathengi abaningi bakholelwa ukuthi amapulasitiki abolayo abhidlika ngokuphelele ngesikhathi esifushane, afana nemfucuza yezinto eziphilayo.
Futhi, i-biodegradation yinqubo eyinkimbinkimbi edinga izimo ezithile zemvelo, njengezinga lokushisa, umswakama, nokuchayeka kumagciwane.Ezimweni eziningi, amapulasitiki abolayo adinga ukucutshungulwa ezindaweni zokuvundisa ezimbonini ukuze aphuke ngokuphelele.Ukuwabeka emgqonyeni ojwayelekile wasekhaya noma osegcekeni kungase kungabangeli ukubola okulindelekile, okuholela ezimangalweni ezidukisayo kanye nokungaqondi kahle izidingo zawo zokulahlwa.
Ukuntuleka kwemithethonqubo emisiwe: Enye inselele enkulu ekusebenziseni amapulasitiki angaboli ukuntuleka kwemithetho emisiwe.Okwamanje ayikho incazelo eyamukelwa umhlaba wonke noma inqubo yokugunyazwa kwezisetshenziswa zelebula ezibolayo.Lokhu kuntuleka kokufana kuvumela abakhiqizi ukuthi benze izimangalo ezingenabufakazi, okuholela abathengi ukuthi bakholelwe ukuthi ipulasitiki abayisebenzisayo ingaphezulu.nemvelokunalokho okuyikho ngempela.
Ukuntula izinto obala nokuziphendulela kwenza kube nzima kubathengi ukuthi benze izinqumo ezinolwazi, kanye nabalawuli ukuthi baqaphe ngempumelelo ukusetshenziswa nokulahlwa kwamapulasitiki abolayo.Umthelela Olinganiselwe Wendawo Ezungezile: Nakuba amapulasitiki abolayo ahlose ukunciphisa ukungcoliswa, umthelela wawo wangempela kwezemvelo uhlala ungaqiniseki.
Olunye ucwaningo luye lwabonisa ukuthi ukukhiqizwa kwamapulasitiki angaboli kukhiqiza igesi ebamba ukushisa eningi kunepulasitiki evamile.Ukwengeza, ukulahla amapulasitiki abolayo ezindaweni zokulahla imfucumfucu kungakhiqiza i-methane, igesi ebamba ukushisa enamandla.Ukwengeza, izinhlobo ezithile zamapulasitiki angaboli zingakhulula izinto eziyingozi ngesikhathi sokubola, zibeka izingozi enhlabathini naseqophelweni lamanzi.
Ngakho-ke, umcabango wokuthi amapulasitiki abolayo ahlala eyindlela evumelana nemvelo udinga ukubuyekezwa.Izinselele zokugaywa kabusha nezinto eziyinkimbinkimbi: Amapulasitiki angaboli adala izinselele ezikhethekile zokugaywa kabusha.Ukuxuba amapulasitiki abolayo namapulasitiki angaboli ngesikhathi sokugaywa kabusha kungangcolisa ukusakaza okugaywa kabusha futhi kwehlise ikhwalithi yezinto ezigaywe kabusha.Ngenxa yalokhu, izindawo zokugaywa kabusha zibhekene nezindleko ezikhulayo nokuba yinkimbinkimbi.
Njengoba kunengqalasizinda esebenza kahle elinganiselwe eklanyelwe ngokuqondile amapulasitiki angaboli, iningi lalezi zinto zisagcina sezindawo zokulahla imfucumfucu, zinganaki izinzuzo zazo zemvelo ezihlosiwe.Ukushoda kwezisombululo ezisebenzisekayo nezingalawuleka zokugaywa kabusha kuphinde kuthikameza ukusebenza kahle kwamapulasitiki angaboli njengezindlela ezisimeme.
Usizi lwamapulasitiki abolayo endaweni yasolwandle: Nakuba amapulasitiki abolayo angase abhidlizwe ngaphansi kwezimo ezikahle, ukulahlwa kwawo kanye nomthelela ongaba khona endaweni yasolwandle kuveza inkinga eqhubekayo.
Ipulasitiki ephelela emanzini njengemifula nolwandle ingase yonakale ngokuhamba kwesikhathi, kodwa lokhu konakala akusho ukuthi ayinangozi ngokuphelele.Ngisho nalapho ebhidlika, la mapulasitiki akhipha amakhemikhali ayingozi nama-microplastics, abeka usongo empilweni yasolwandle nasezimisweni zemvelo.
Amapulasitiki abolayo, uma engaphathwa ngendlela efanele, angabhebhethekisa ukungcoliswa kwepulasitiki emkhakheni wezamanzi, adicilele phansi imizamo yokuvikela imvelo yasolwandle entekenteke.
Sengiphetha: Amapulasitiki angaboli avela njengesixazululo esithembisayo enkingeni yomhlaba wonke yokungcoliswa kwepulasitiki.Nokho, ukusetshenziswa kwazo okungokoqobo kubangela izinselele nemingcele ehlukahlukene.
Izimangalo ezidukisayo, ukungaqondi kahle kwabathengi, ukuntuleka kwemithethonqubo emisiwe, umthelela ongaqinisekile wemvelo, izinto eziyinkimbinkimbi zokugaywa kabusha kwezinto, kanye namandla okuqhubeka nokungcoliswa kolwandle konke kube nomthelela ezinkingeni ezihlobene namapulasitiki abolayo.
Ukuze unqobe lezi zithiyo, indlela ehlanganisa zonke izinto ibalulekile.Le ndlela kufanele ibandakanye ukuthathwa kwezinqumo okunolwazi ngabathengi, imithetho eqinile nevunyelaniswe emhlabeni wonke, intuthuko kubuchwepheshe bokuvuselela kabusha, kanye nokukhula obala kwabakhiqizi.
Ekugcineni, izixazululo ezisimeme zenkinga yokungcoliswa kwepulasitiki zidinga ukuncishiswa kokusetshenziswa kwepulasitiki sekukonke futhi kugqugquzelwe ukusetshenziswa kwezinto ezivikela imvelo ngempela, kunokuthembela kuphela kumapulasitiki abolayo.
