Aluminium extrusion ke ts'ebetso e sebelisoang haholo ea tlhahiso e kenyelletsang ho bopa aluminium ka ho e qobella ka menyetla e entsoeng ka har'a thapo. Ts'ebetso ena e tumme ka lebaka la ho feto-fetoha ha aluminium le ho tšoarella, hammoho le khabone ea eona e tlase ha e bapisoa le lisebelisoa tse ling. Leha ho le joalo, tlhahiso ea aluminium e ntse e hlahisa likhase tse ngata tsa carbon dioxide, tse nang le tšusumetso tikolohong.

Thetlhahiso ea aluminiume akarelletsa ho ntšoa ha tšepe ea bauxite, ebe e hloekisoa hore e be alumina, ebe e qhibilihisoa hore e be aluminium. Ts'ebetso ena e nka matla haholo 'me e ntša carbon dioxide, e leng se eketsang matla a indasteri a k'habone. Ebile, indasteri ea aluminium e ntša hoo e ka bang 1% ea likhase tsa CO2 lefatšeng ka bophara.

Ho sebetsana le phello ea tikoloho ea tlhahiso ea aluminium, ho ntse ho etsoa boiteko ba ho fokotsa khabone ea indasteri. Mokhoa o mong ke oa ho tsepamisa maikutlo ho nts'etsopele mekhoa ea tlhahiso ea aluminium ea khabone e tlase. Sena se kenyelletsa ho sebelisa mehloli ea matla e ka nchafatsoang joalo ka matla a fehloang ka metsi kapa matla a letsatsi ho matlafatsa ts'ebetso ea ho qhibilihisa, ka hona ho fokotsa ho itšetleha ka libeso tsa khale le ho theola likhase tsa CO2.

Ho feta moo, tsoelo-pele ea theknoloji e ekelitse katleho ea tlhahiso ea aluminium, kahoo e fokotsa tšebeliso ea matla le ho theola mocheso oa CO2 ka tonne ea aluminium. Ho sebelisa aluminium hape ho phetha karolo ea bohlokoa ho fokotseng khabone ea indasteri, kaha aluminium ea ho sebelisa hape e hloka matla a fokolang haholo ha a bapisoa le tlhahiso ea mantlha, e leng se bakang phokotso e kholo ea mesi ea CO2.

Tlhahiso ea aluminium ea nalane le e lebelletsoeng ea mantlha le e sebelisitsoeng hape e se e holile mme e ntse e hola ho tloha 1950 ho isa 2050, mme karolo ea aluminium e nchafalitsoeng e ntse e eketseha (Mokitlane: IAI Material Flow Update)

Ho feta moo, ts'ebeliso ea aluminium extrusion liindastering tse fapaneng e fana ka melemo ea ts'ebetso kaha e bobebe, e tšoarella ebile e ka sebelisoa hape ka botlalo. Sena se kenya letsoho moruong oa selikalikoe ka ho khothaletsa tšebeliso hape ea lihlahisoa tsa aluminium le ho fokotsa tlhoko ea tlhahiso ea mantlha.

Qetellong, ha tlhahiso ea aluminium e etsa tlhahiso ea CO2, indasteri e 'nile ea sebetsa ka mafolofolo ho fokotsa carbon footprint. Nts'etsopele ea mekhoa ea tlhahiso ea aluminium e nang le carbon e tlaase, ntlafatso ea matla a matla le ho khothalletsa ho tsosolosoa ha aluminium kaofela li kenya letsoho ntlafatsong e tsitsitseng le botsoalle ba tikoloho ea indasteri ea aluminium. Ka ho tsoela pele ho beha boiteko bona pele, indasteri e ka tsoela pele ho fokotsa tšusumetso ea eona ea tikoloho le ho kenya letsoho bokamosong bo botala.
