Nk’uko byatangajwe n’itangazamakuru ryo mu mahanga, inganda zikora ibyuma zo muri Amerika Nucor, Cleveland Cliffs n’uruganda rwa BlueScope Steel Group rukora ibyuma bya North Star muri Leta Zunze Ubumwe za Amerika zizashora imari irenga miliyari imwe y’amadolari mu gutunganya ibisigazwa by’ibikoresho mu 2021 kugira ngo zihuze n’izamuka ry’ibiciro ku isoko ry’imbere mu gihugu muri Leta Zunze Ubumwe za Amerika.
Bivugwa ko umusaruro w'ibyuma muri Amerika uziyongeraho hafi 20% mu 2021, kandi abakora ibyuma muri Amerika barimo gushaka ibikoresho fatizo bihoraho biva mu modoka zashaje, imiyoboro ya peteroli yakoreshejwe n'imyanda ikoreshwa mu nganda. Hashingiwe ku kongera ubushobozi bwo gukora toni miliyoni 8 kuva mu 2020 kugeza 2021, inganda z'ibyuma muri Amerika zitezweho kongera ubushobozi bwo gukora ibyuma bitagira ingano buri mwaka mu gihugu ho toni miliyoni zigera ku 10 mu 2024.
Birumvikana ko icyuma gikorwa n'uburyo bwo gushongesha ibyuma bishaje bushingiye ku itanura ry'amashanyarazi ubu kigize hafi 70% by'umusaruro wose w'ibyuma muri Leta Zunze Ubumwe za Amerika. Uburyo bwo gukora butanga imyuka mike ya dioxyde de carbone ugereranyije n'amabuye y'agaciro ashongeshwa mu itanura rishyushya amakara, ariko kandi binashyira igitutu ku isoko ry'ibisigazwa muri Amerika. Dukurikije imibare yavuye mu kigo cy'ubujyanama cya Metal Strategies cyo muri Pennsylvania, ibisigazwa byaguzwe n'abakora ibyuma muri Amerika byazamutseho 17% mu Ukwakira 2021 ugereranyije n'umwaka ushize.
Dukurikije imibare yavuye muri World Steel Dynamics (WSD), mu mpera za 2021, ibiciro by'ibyuma bishaje byo muri Amerika byazamutseho impuzandengo ya 26% kuri toni ugereranije n'igihe nk'icyo muri 2020.
“Uko inganda z’ibyuma zikomeza kwagura ubushobozi bwazo bwa EAF, umutungo w’ibisigazwa by’ubuziranenge uzarushaho kuba muke,” ibi byavuzwe na Philip Anglin, Umuyobozi Mukuru wa World Steel Dynamics.
