Mu myaka egiyise, n’okugaziya amakolero ga aluminiyamu ag’amasannyalaze ag’ensi yonna, anode butts, nga ekikulu nga-ekiva mu nkola y’okufulumya aluminiyamu ey’amasannyalaze, byeyongedde okuba eby’omuwendo mu kuddamu okukola n’okuddamu okukozesa. Anode butts ezikozesebwa zisinga kubaamu ebintu bya kaboni, ebiyinza okuddamu okukozesebwa mu butoffaali bw’amasannyalaze aluminiyamu oba okulongoosebwa mu bintu ebirala ebya kaboni oluvannyuma lw’okulongoosebwa, nga birimu emigaso mingi mu by’enfuna n’obutonde.
Okuva ku ludda lw’okugabira akatale, ebifulumizibwa mu nsi yonna ebya anode butts bikwatagana butereevu n’obusobozi bw’okufulumya aluminiyamu obw’amasannyalaze. China, North America ne Bulaaya zikyali ebitundu ebikulu ebikola ebintu, nga mu bino China, ng’esinga okukola aluminiyamu ow’amasannyalaze mu nsi yonna, ekola ebitundu ebisoba mu 60% ku bifulumizibwa mu nsi yonna ebya anode butts ezikozesebwa. Wabula olw’okunyweza enkola z’okukuuma obutonde bw’ensi n’okutereeza obusobozi bw’okufulumya aluminiyamu obw’amasannyalaze, omutindo gw’okukula kw’ebifulumizibwa mu anode butts mu bitundu ebimu gukendedde. Okugatta ku ekyo, enzimba y’enkola y’okuddamu okukola kasasiro nayo ekosa butereevu obutebenkevu bw’akatale.
Mu ngeri y’obwetaavu, obutale obukulu obw’abaguzi obw’enkasi za anode ezikozesebwa bukuŋŋaanyizibwa mu bitongole bya aluminiyamu eby’amasannyalaze ebya aluminiyamu, abakola ebintu bya kaboni n’ebitongole ebikola ku by’obugagga ebizzibwa obuggya. Okuva omuwendo gw’ebintu ebikozesebwa mu kukola kaboni ebikozesebwa mu kuddamu okukola (recycled carbon materials) bwe guli wansi okusinga ogw’ebintu ebitali bimu, kkampuni nnyingi zitera okugula kasasiro wa anode asigaddewo okuddamu okulongoosa okukendeeza ku nsaasaanya y’okufulumya. Mu kiseera kye kimu, n’okukulaakulana kw’ebigendererwa by’obutabeera na kaboni, okuddamu okukola kasasiro wa anode asigaddewo nakyo kifuuse ekifo ekikulu eky’okufaayo kw’amakolero, ekivaako enkulaakulana ey’amaanyi mu bwetaavu.
Mu katale k’ensi yonna, enkola y’obusuubuzi bw’ebisasiro bya anode ebisigaddewo eraga engeri z’ekitundu. Ekitundu kya Asia kisinga kwesigamiziddwa ku ntambula y’omunda, ate obutale bwa Bulaaya ne Amerika bwesigamye ku bintu ebiyingizibwa mu ggwanga naddala obwetaavu bw’ebisasiro eby’omutindo ebya waggulu-eby’omutindo binywevu nnyo. Emiwendo gy’obusuubuzi gikosebwa ensonga eziwera nga enkyukakyuka mu bintu ebisookerwako, ssente z’entambula n’enkola z’okukuuma obutonde bw’ensi, era zikyukakyuka okutuuka ku ddaala eritali limu mu myaka egiyise.
Mu biseera eby’omu maaso, ng’amakolero ga aluminiyamu agakola amasannyalaze ag’ensi yonna gakyuka ne gatuuka ku nkulaakulana eya kiragala era ennungi, tekinologiya ow’okuddamu okukola ebintu ebisigaddewo anode asuubirwa okwongera okulongoosebwa, era obwetaavu bw’akatale k’ensi yonna ku bwayo buyinza okugenda mu maaso n’okugaziwa. Ku bakola ku by’obusuubuzi okuva ebweru, okussaayo omwoyo ku nkyukakyuka mu nkola y’ekitundu n’enkyukakyuka mu by’okuwaayo n’obwetaavu kijja kuyamba okukwata emikisa egiyinza okubaawo mu katale ka anode waste market akasigaddewo.
