Isitini esingashisiwe siwuhlobo olusha lwempahla yodonga eyenziwe ngomlotha wempukane, i-cinder, i-gangue yamalahle, i-tail slag, i-slag yamakhemikhali noma isihlabathi semvelo, udaka olusogwini (okukodwa noma ngaphezulu kwezinto zokusetshenziswa ezingenhla) ngaphandle kokubala ukushisa okuphezulu.

Ngokuthuthuka okuqhubekayo kokuthuthuka kwezindawo zasemadolobheni, ziya ngokuya zikhula imfucuza yokwakha eminyakeni yamuva, okulethe izinkinga emnyangweni wokuphatha amadolobha. Uhulumeni uye waqaphela kancane kancane ukubaluleka kokuphathwa kwemithombo yemfucuza yokwakha; Ngokomunye umbono, imfucuza yokwakha nayo iwuhlobo lomcebo. Ngemuva komugqa wokukhiqiza izitini we-Leishi Chengxin, ungaba udonga olusha olutholakala kalula ezikhathini zanamuhla, futhi ususetshenziswe ngokugcwele.

I-Fly ash yiyona engcolisa kakhulu imvelo. E-China, okukhiphayo kufinyelela izinkulungwane zamathani, futhi iningi lazo alisetshenziswa, elingachithi nje izinsiza, kodwa futhi libangele ukungcoliswa kwemvelo okwandayo. Eqinisweni, i-fly ash ibuye ibe yinto enhle yokwenza izitini. Ngemuva komugqa wokukhiqiza izitini weLeishi Chengxin, ungaba futhi udonga olusha olutholakala kalula ezikhathini zanamuhla, oselusetshenziswe ngokugcwele.

Hhayi nje kuphela imfucuza yokwakha, umlotha wempukane, imsila, ukuncibilika kwensimbi nokunye okulahlwayo okuqinile, umshini wezitini zokwakha udoti ongashi weLei Shi Chengxin ungaguqula imfucumfucu ibe umcebo, futhi “ingane” ekhiqiziwe iyasebenza nasekugcinweni kwamanzi, udonga, inhlabathi, ingadi nezinye izici!
