Ukusetyenziswa kweBhokisi yeNxulumano yoBubungqina bokudubula

Iibhokisi zesiphambuka ezikhusela uqhushumbo zizinto ezibalulekileyo ekuqinisekiseni ukhuseleko kwiindawo eziyingozi. Ezi bhokisi ziphawulwa ngeempawu zazo ezibalaseleyo zokutywina kunye nesakhono esinamandla sobungqina bokudubula, efana nesikhongozeli esitywinwe ngokukhuselekileyo.

Isetyenziswa ikakhulu kumashishini apho imingcipheko yoqhushumbo ixhaphakile, njengamacandelo ekhemikhali kunye namayeza, zibalulekile ekufakeni iingcingo kunye nokuhanjiswa kweentambo zezixhobo kwindawo eqhumayo njengezityalo zeoyile kunye nepetrochemical.. Uyilo lwazo luhambelana nemigangatho engqongqo yokhuseleko, ukubonelela ngesisombululo esithembekileyo sokuxhamla kombane kwiindawo ezinomngcipheko ophezulu.
