Bivugwa ko umusaruro w’ibikoresho birwanya ubushyuhe ku isi wageze kuri toni 45×106 ku mwaka, kandi wakomeje kuzamuka uko umwaka utashye.
Inganda z'ibyuma ziracyari isoko rikomeye ry'ibikoresho birwanya ubushyuhe, zikoresha hafi 71% by'umusaruro wa buri mwaka w'ibikoresho birwanya ubushyuhe. Mu myaka 15 ishize, umusaruro w'ibyuma bihumanya ku isi wikubye kabiri, ugera kuri toni 1,623 × 106 mu 2015, muri zo hafi 50% bikorerwa mu Bushinwa. Mu myaka mike iri imbere, kwiyongera kwa sima, ibumba n'ibindi bikomoka ku mabuye y'agaciro bizahuza n'iyi gahunda yo kwiyongera, kandi kwiyongera kw'ibikoresho birwanya ubushyuhe bikoreshwa mu gukora amabuye y'agaciro y'icyuma n'atari ibyuma bizakomeza iterambere ry'isoko. Ku rundi ruhande, ikoreshwa ry'ibikoresho birwanya ubushyuhe mu bice byose rikomeje kugabanuka. Kuva mu mpera za 1970, ikoreshwa rya karuboni ryabaye ikintu cy'ingenzi. Amatafari adatwitswe arimo karuboni yakoreshejwe cyane mu bikoresho bikora ibyuma n'ibyuma kugira ngo agabanye ikoreshwa ry'ibikoresho birwanya ubushyuhe. Muri icyo gihe, Castables nke zatangiye gusimbura amatafari menshi arwanya ubushyuhe. Ibikoresho birwanya ubushyuhe, nk'ibikoresho birwanya ubushyuhe n'ibikoresho bitera ubushyuhe, si byo byonyine binoza ibikoresho ubwabyo, ahubwo ni no kunoza uburyo bwo kubaka. Ugereranyije n'urukuta rudafite ishusho y'urutare rurerure rw'ikintu gifite ishusho, imiterere yarwo yihuta kandi igihe cyo gukora itanura kiragabanuka. Bishobora kugabanya cyane ikiguzi.
Ibikoresho bitagira ishusho bigizwe na 50% by'isoko ry'isi, cyane cyane amahirwe yo kwiyongera kw'ibikoresho bya castable na preforms. Mu Buyapani, nk'icyitegererezo cy'icyerekezo cy'isi, ibikoresho bitagira ishusho imwe byamaze kugira 70% by'umusaruro wose wa réfractory mu 2012, kandi isoko ryabyo ryakomeje kwiyongera.
