Le ndlela ibandakanya ukuqulunqa amayeza ukukhulula izithako zawo ezisebenzayo ngokuthe ngcembe kwithuba elide, okukhokelela ekugxininiseni kwamachiza okuzinzile emzimbeni, ukunciphisa ukuphindaphinda kwedosi, kunye neziphumo ebezingalindelekanga ezimbalwa. Eli nqaku liphonononga imigaqo, iinzuzo, izicelo, kunye nezikhokelo zexesha elizayo zokunikezelwa kweziyobisi ezizinzileyo, ukubonelela ngombono obanzi wesi sicwangciso sonyango esibalulekileyo.

Ukuqonda Ukuhanjiswa kweziyobisi okuZinzileyo

Ukukhululwa konyango lokunikezelwa kweziyobisi, okwakwaziwa njengokukhululwa-kwandisiweyo okanye ukukhutshwa-okulawulwayo, yindlela yolawulo lwechiza elikhupha iyeza emzimbeni ngokuthe ngcembe kwixesha elide. Ngokungafaniyo namayeza akhutshwa kwangoko, akhupha idosi yonke ngexesha elinye, iinkqubo zokukhutshwa okuzinzileyo zenzelwe ukugcina amanqanaba eyeza zonyango ixesha elide. Oku kuphunyezwa ngezicwangciso ezahlukeneyo zokuqulunqa ezilawula izinga apho ichiza likhutshwa kwifomu yedosi.

Imigaqo yoKhupho oluZinzileyo

Umgaqo ongundoqo we Ukukhutshwa okuzinzileyo konyango lokuhanjiswa kweziyobisi ilele ekulawuleni izinga lokukhutshwa kwechiza ukuze kuphunyezwe inkangeleko yonyango efunekayo. Zininzi izinto ezinefuthe kolu khululo, kuquka:

• Iimpawu zeziyobisi: Ukunyibilika, ubunzima bemolekyuli, kunye nokuzinza kwechiza.
• Uyilo loqulunqo: Uhlobo lwepolymer esetyenzisiweyo, isakhiwo sematrix, kunye nobukho beengubo.
