Muri Kamena, ibicuruzwa byoherejwe na electrode ya grafite byagabanutse ugereranije n'ukwezi gushize, mu gihe ibyoherezwa mu Burusiya byiyongereye.

Nk’uko imibare ya gasutamo ibigaragaza, mu Bushinwa ibyoherezwa mu mahanga na electrode ya grafite muri Kamena byari toni 23100, byagabanutseho 10.49 ku ijana ugereranije n’ukwezi gushize kandi byiyongereyeho 6.75 ku ijana mu gihe kimwe n’umwaka ushize.Ibicuruzwa bitatu bya mbere byoherezwa mu mahanga ni Uburusiya toni 2790, Koreya y'Epfo toni 2510 na Maleziya toni 1470.

Kuva muri Mutarama kugeza muri Kamena 2023, Ubushinwa bwohereje toni 150800 za electrode ya grafite, bikiyongeraho 6.03% ugereranije n’icyo gihe cyo mu 2022. Kubera intambara y’Uburusiya na Ukraine ndetse n’ubumwe bw’ibihugu by’Uburayi birwanya guta, umubare wa 2023H1 Ubushinwa bwa grafite electrode yohereza mu Burusiya bwiyongereye, mu gihe ibyo mu bihugu by’Uburayi byagabanutse.
