Kuva mu ntangiriro za 2020, icyorezo gishya cy'ikamba cyamamaye ku isi kandi cyagize ingaruka ku nganda za PCB ku isi.Ubushinwa bwasesenguye buri kwezi amakuru yoherezwa mu mahanga ya PCB yo mu Bushinwa yashyizwe ahagaragara n'Ubuyobozi Bukuru bwa gasutamo.Kuva muri Werurwe kugeza Ugushyingo 2020, Ubushinwa bwa PCB bwohereza ibicuruzwa mu mahanga bwageze kuri miliyari 28, umwaka ushize bwiyongeraho 10.20%, bikaba byaragaragaye cyane mu myaka icumi ishize.

Muri byo, kuva muri Werurwe kugeza muri Mata 2020, Ubushinwa bwohereza ibicuruzwa mu mahanga PCB bwiyongereye ku buryo bugaragara, bwiyongereyeho 13.06% na 21.56% umwaka ushize.Impamvu zo gusesengura: bitewe n’icyorezo mu ntangiriro za 2020, igipimo cy’imikorere y’inganda za PCB mu Bushinwa ku mugabane w’Ubushinwa, kongera koherezwa nyuma yo kongera akazi, no kongera inganda zo mu mahanga.

Kuva muri Nyakanga kugeza Ugushyingo 2020, Ubushinwa bwohereza ibicuruzwa mu mahanga PCB bwiyongereye cyane ku mwaka ku mwaka, cyane cyane mu Kwakira, bwiyongereyeho 35,79% umwaka ushize.Ibi birashobora guterwa ahanini no kugarura inganda zo hasi no gukenera inganda za PCB zo hanze.Muri iki cyorezo, ubushobozi bwo gutanga inganda za PCB mu mahanga ntizihinduka.Isosiyete nkuru yubushinwa ikora ibicuruzwa byohereza hanze.

Dukurikije imibare ya Prismark, kuva mu 2016 kugeza mu 2021, umuvuduko w’ubwiyongere bw’agaciro k’umusaruro wa buri gice cy’inganda za PCB mu Bushinwa uri hejuru ugereranyije n’ikigereranyo cy’isi yose, cyane cyane mu buhanga buhanitse nko ku mbaho ​​zo hejuru, ku mbaho ​​za HDI, ku mbaho ​​zoroshye. no gupakira ibikoresho.PCB.Fata ibikoresho byo gupakira nk'urugero.Kuva mu 2016 kugeza 2021, igihugu cyanjye gipakira ibicuruzwa biva mu mahanga biteganijwe ko biziyongera ku gipimo cy’ubwiyongere bw’umwaka kingana na 3.55%, mu gihe impuzandengo y’isi ari 0.14% gusa.Inzira yo kohereza inganda iragaragara.Icyorezo giteganijwe kwihutisha ihererekanyabubasha rya PCB mu Bushinwa, no kwimura Ni inzira ikomeza.
