Imiphumela yokusebenzisa igazi lomthwakazi iyisiphephelo esihle kwezindustria zomthwakazi wokubhala nokungabhalanga kuzo zonke, ngokuphakeme kuzo izindlela zokugcina nokukhupha. Kuzo zizindlela zokusebenza kwemithwakazi yezinkambu, imiphumela yokusebenzisa igazi isebenza ngokuphakeme kuzo izinto eziphathelene nezinhlobo zokusebenza kwezinkambu nokugcina, ukuqinisa ukuthi izigazi njenge-blast furnace gas (BFG) ziphathelwe ngokuphelele, zihlakaziswa futhi zisebenziswe kabusha ekuphakameni okanye ekugeneratheni kwamandla. Ngokuhlela ukuvulwa kwegazi nokubhekana nesilinganiso sawo, le miphumela ihlala iphakamisa ukusetshenziswa kwemithwakazi yezinkambu futhi ihlela ukusebenza kwamandla kwezinkambu, okuyisiphumo sokuphakama kwezindlela zokusebenza futhi ukunciphisa indawo yokusebenza yezindawo zokusebenza kanye nokunciphisa ukuthi kubhekene nendawo yezinsizakalo.
Ngaphezu kwezindlela zokuproducwa kwemithambo yezinkulu, lezi zisilungiselelo zesigasizinye zingaba zizinga kakhulu kwezindlela zokuphatha kabusha nokuzikhathazisa. Kuzindlela zokusebenza njengezindlela zokusebenza kwe-BOF (basic oxygen furnaces) noma kwezindlela zokusebenza kwe-EAF (electric arc furnaces), ukulawula kahle kwesigasizinye—kufuneka kubekwe ukuthi kuthakelwe i-argon noma i-nitrogen—kuyidinga kakhulu ukuthi kusukwane isilwane esisodwa ukuze kufikelele kuqinisekiswa kwesilinganiso sesilinganiso sesihlathi nesibalo sezinhlobo zemithambo. Ngaphezu kwalokho, kuzindlela zokuzikhathazisa nokuzikhipha izimithambo, izimo ezilawulwa ngokuphelele zokusebenza kwezisilungiselelo zesigasizinye zisindisa ukuthi kuhlanganise isilwane noma kwenziwe isilwane sokugqaza, okunika ubukhulu obuhle bocingo lwemithambo yokuqala.
Isiphakade sesikhundla sesoloko sezinkampani zokusebenzisa izigashe zokufunda izinto zisifaka ukugcina ikabhonu nokwenza izistili ezihle. Ngokuthi indusitri ithintela kusukela kumkhakha wokuphatha ngokuhle, lezi zinhlelo manje zizakhiwe ukuze zincongise nezithintela i-CO2 noma ukusiza ukusebenzisa izinkampani zokuthintela ezingaphansi kwezinye, njengokusebenzisa i-hydrogen. Ngokufaka amatekhnoloji okuhlanganisa izigashe nokucleansa kahle, izinhlelo zesoloko sezinkampani zokufunda izinto ziyagcina indlela yokwenza ukufunda izinto ngokwesikhundla esincane kwekabhonu, ukuvumela abasebenzi bakwazi ukubona izimfuneko eziningi zokuphatha ngokuhle kwezwe ngokuthi bakhangele isikhundla esiphelele sokusebenza.

Emva kokuthi sibhekisile le miphumela yokuzimisa imithambo yezinkulungwane, siyabeka ubude bokugcina kwezinkulungwane ngokuphatha ngokuphansi ngo-12%, sibekisa amakhombe amaningi emithambo yezinkulungwane ngonyaka.
Ubukhulu bekho kwezinhlelo zokusebenzisa amagasi emetalurgi kubambele ukuthi sibuye sibuyise isikhathi sokulawula umoya wendawo yokuqinisa, okuvumela ukuthi ngalokho kufanele kubhekwe isikhathi esihle kuzo zonke izigaba.
