Bigereranijwe ko umusaruro w’ibikoresho byo kwangirika ku isi wageze kuri 45 × 106t ku mwaka, kandi ukomeza kuzamuka mu mwaka.
Inganda zibyuma ziracyari isoko nyamukuru ryibikoresho bivunika, bitwara hafi 71% yumusaruro wumwaka. Mu myaka 15 ishize, umusaruro w’ibyuma bya peteroli ku isi wikubye kabiri, ugera kuri 1,623 × 106t muri 2015, muri byo hafi 50% bikorerwa mu Bushinwa. Mu myaka mike iri imbere, ubwiyongere bwa sima, ububumbyi n’ibindi bicuruzwa by’amabuye y'agaciro bizuzuza iyi nzira yo gukura, kandi kwiyongera kw'ibikoresho bivunika bikoreshwa mu gukora ibicuruzwa by'amabuye y'agaciro n'ibyuma bitarimo ibyuma bizakomeza kuzamura isoko. Kurundi ruhande, ikoreshwa ryibikoresho bivunika mubice byose bikomeje kugabanuka. Kuva mu mpera za za 70, ikoreshwa rya karubone ryibanze. Amatafari arimo karuboni adatwitswe yakoreshejwe cyane mubikoresho byo gukora ibyuma nicyuma kugirango bigabanye gukoresha inganda. Muri icyo gihe, sima nkeya Castable yatangiye gusimbuza amatafari menshi adafite karubone. Ibikoresho bitavunitse bidafite ishusho, nkibikoresho byo guteramo ibikoresho, ntabwo ari ugutezimbere ibikoresho ubwabyo, ahubwo ni no kunoza uburyo bwo kubaka. Ugereranije nuburyo butavunitse butondekanya ibicuruzwa byakozwe, ubwubatsi bwihuta kandi igihe cyo gucana kigabanuka. Irashobora kugabanya cyane ibiciro.
Inganda zidafite ishusho zingana na 50% byisoko ryisi yose, cyane cyane iterambere ryiterambere rya castable na preforms. Mu Buyapani, nkuyobora inzira yisi yose, inganda za monolithic zimaze kugera kuri 70% yumusaruro wose wangiritse muri 2012, kandi umugabane wabo ku isoko wakomeje kwiyongera.
