I-Aluminium extrusion iyinqubo yokukhiqiza esetshenziswa kabanzi ebandakanya ukubumba i-aluminium ngokuyiphoqa ngokusebenzisa izimbobo ezakhiwe endaweni yokufa. Le nqubo idumile ngenxa yokuguquguquka nokusimama kwe-aluminium, kanye ne-carbon footprint yayo ephansi uma kuqhathaniswa nezinye izinto. Kodwa-ke, ukukhiqizwa kwe-aluminium kusakhiqiza amanani abalulekile wokukhishwa kwe-carbon dioxide, okunomthelela emvelweni.

Iukukhiqizwa kwe-aluminiumkuhilela ukukhishwa kwensimbi ye-bauxite, ebese icwengisiswa ibe i-alumina, ebese incibilikiswa ibe i-aluminium. Le nqubo idinga amandla amaningi futhi ikhipha isikhutha, okwandisa izinga lekhabhoni lemboni. Eqinisweni, imboni ye-aluminium ikhipha cishe u-1% wokukhishwa kwe-CO2 emhlabeni jikelele.

Ukubhekana nomthelela wemvelo wokukhiqizwa kwe-aluminium, kwenziwa imizamo yokunciphisa izinga lekhabhoni lemboni. Enye indlela ukugxila ekuthuthukiseni izindlela zokukhiqiza i-aluminium enekhabhoni ephansi. Lokhu kuhilela ukusebenzisa imithombo yamandla avuselelekayo njengamandla aphehlwa ngamanzi noma amandla elanga ukuze kunikwe amandla inqubo yokuncibilikisa, ngaleyo ndlela kwehliswe ukuthembela kumafutha ezinto ezimbiwa phansi kanye nokwehlisa ukukhishwa kwe-CO2.

Ngaphezu kwalokho, intuthuko yezobuchwepheshe ikhulise ukusebenza kahle kokukhiqizwa kwe-aluminium, ngaleyo ndlela kunciphisa ukusetshenziswa kwamandla futhi yehlisa ukukhishwa kwe-CO2 ngethani ngalinye le-aluminium. Ukugaywa kabusha kwe-aluminiyamu nakho kudlala indima ebalulekile ekwehliseni i-carbon footprint yemboni, njengoba ukugaya kabusha i-aluminium kudinga amandla amancane kakhulu uma kuqhathaniswa nokukhiqizwa okuyinhloko, okuholela ekwehleni okukhulu kokukhishwa kwe-CO2.

Ukukhiqizwa kwe-aluminium okungokomlando nokucatshangelwayo okuyinhloko kanye ne-recycled aluminium sekukhulile futhi kuyakhula kusukela ngo-1950 kuya ku-2050, futhi ingxenye ye-aluminium egaywe kabusha iyanda (Isikweletu: I-IAI Material Flow Update)

Ngaphezu kwalokho, ukusetshenziswa kwe-aluminium extrusion ezimbonini ezahlukahlukene kunikeza izinzuzo zokusimama njengoba ilula, iqinile futhi igaywa kabusha ngokuphelele. Lokhu kunomthelela emnothweni oyindilinga ngokugqugquzela ukusetshenziswa kabusha kwemikhiqizo ye-aluminium kanye nokunciphisa isidingo sokukhiqiza okuyisisekelo.

Sengiphetha, ngenkathi ukukhiqizwa kwe-aluminium kukhiqiza i-CO2 ekhishwayo, imboni ibisebenza ngenkuthalo ukwehlisa izinga layo lekhabhoni. Ukuthuthukiswa kwezindlela zokukhiqiza i-aluminium enekhabhoni ephansi, ukuthuthukiswa kokusebenza kahle kwamandla kanye nokukhuthazwa kokugaywa kabusha kwe-aluminium konke kunomthelela ekuthuthukisweni okusimeme kanye nobungane bemvelo embonini ye-aluminium. Ngokuqhubeka nokubeka phambili le mizamo, imboni ingaqhubeka nokunciphisa umthelela wayo kwezemvelo futhi ibe negalelo ekusaseni eliluhlaza.
