Imveliso yehlabathi plastiki ukunyuka rhoqo ngonyaka (i-288 yezigidi zeetoni, oko kukuthi, ngaphezulu kwe-2,9% ngo-2012), ngokunxulumene ngqo nokukhula kwabemi, kwaye ngenxa yoko, ngokunyuka kwemali inkunkuma.
Kuvele ngeminyaka yoo-1950, ezi izinto Ubuninzi buphendula ekusebenziseni okuninzi okungenakuphepheka namhlanje. Ngenxa yeempawu zabo ezithile - ucoceko, ukunganyangeki, njl. Njl., Iiplastiki ziyinxalenye yobomi bethu bemihla ngemihla, ngakumbi ekupakisheni, okwangoku emele ama-66% inkunkuma plastiki.
La mveliso ngokusemthethweni yeengxowa zeplastiki ezaziphuphuma ngoo-1970, zifikelela kumanani eenkwenkwezi ngonyaka. Uninzi lwenkunkuma luphela luthatha umendo we imijelo yogutyulo, imilambo nolwandle. Inkqubo ye- iminikelo yasemhlabeni yiyo loo nto bemele i-80% yenkunkuma efikelela elwandle.
Ngokuphathelele inkunkuma elwandle, Siqinisekisa ukuba ubukhulu becala yimvelaphi yolwandle IAtlantic nasemhlabeni ku IMeditera. Izigidi ezithandathu zeetoni zenkunkuma ziyagxothwa minyaka le ziinqanawa. KuLwandle lwaseMantla, iipesenti ezingama-90 zenkunkuma efumanekayo Ukupakishwa kweplastikhi (iingxowa, iibhotile).
