Yamkela uyilo olujikelezayo, olusetyenziselwa ukuhlamba iibhotile ezingenanto zejusi kunye namanzi njl njl. Emva koko udlulisele iibhotile ezicocekileyo kwindawo yokuzalisa.
Iibhotile ze-PET zokungena kwizixhobo ngevili leenkwenkwezi, iibhotile ziboshwe kwaye zibuyiselwe umva ukwenza ibhotile ibe phantsi.Ukuhlamba ngamanzi acocisayo kwaye ukhuphe kakuhle, emva koko ujike ibhotile ngokuzenzekelayo.Isakhiwo esiphambili kunye nenxalenye yokuhlamba yenziwe ngensimbi engenasici, isakhiwo esilula kunye nokulungelelaniswa lula;Ukudibana okuncinci kunye ne-bottleneck, enokuthi iphephe ukungcoliseka kwesibini ngokufanelekileyo.
