Imbere ninyuma yumuzingi wa pcb mubyukuri ni umuringa. Mugukora imiyoboro ya pcb, ntakibazo cyaba icyiciro cyumuringa cyatoranijwe kubiciro byigiciro gihinduka cyangwa imibare ibiri yongeyeho no gukuramo, ibisubizo byanyuma nubuso bworoshye kandi butabungabunzwe. Nubwo imiterere yumuringa idashimishije nka aluminium, fer, magnesium, nibindi, hashingiwe ku rubura, umuringa mwiza na ogisijeni byoroshye cyane okiside; urebye kubaho kwa co2 hamwe numwuka wamazi mwikirere, hejuru yumuringa wose Nyuma yo guhura na gaze, reaction ya redox izabaho vuba. Urebye ko ubunini bwurwego rwumuringa mumuzunguruko wa PCB ari ruto cyane, umuringa nyuma yo guhumeka ikirere uzahinduka amashanyarazi adahwitse, bizangiza cyane ibikoresho byamashanyarazi biranga imiyoboro yose ya PCB.

Mu rwego rwo kwirinda neza okiside yumuringa, no gutandukanya neza gusudira no kudasudira ibice byo gusudira byumuzunguruko wa pcb mugihe cyo gusudira amashanyarazi, kandi kugirango tubungabunge neza ubuso bwumuzunguruko wa pcb, abahanga mubuhanga bashizeho Ubwubatsi budasanzwe. Kwambara. Bene ubwo bwubatsi bushobora gusukurwa byoroshye hejuru yumuzunguruko wa PCB, bikavamo umubyimba wurwego rukingira rugomba kuba ruto kandi rukabuza guhuza umuringa na gaze. Uru rupapuro rwitwa umuringa, kandi ibikoresho bibisi byakoreshejwe ni mask yo kugurisha
