Ewe, ngokwengxelo yakutshanje ngeUmbutho weAluminiyamkwayeNgaba iZiko labaVelisi(CMI) -I-Aluminiyam ingenza i-Advanteji: Uzinzo lweZalathi zokuSebenza eziphambili ngo-2021- ebonisa izibonelelo eziqhubekayo zokuzinza kwesikhongozeli sesiselo se-aluminium xa kuthelekiswa neentlobo zokupakisha ezikhuphisanayo. Ingxelo ihlaziya izalathisi ezininzi zokusebenza eziphambili (KPI) ngo-2020 kwaye ifumanisa ukuba abathengi baphinde basebenzise iinkonkxa ze-aluminiyam ngaphezulu kwenqanaba eliphindwe kabini leebhotile zeplastiki (PET). Iitoti zesiselo ze-Aluminiyam nazo ziqulathe naphi na ukusuka kwi-3X ukuya kwi-20X ngaphezulu komxholo ohlaziyiweyo kuneglasi okanye iibhotile ze-PET kwaye zixabiseke kakhulu njenge-scrap, okwenza i-aluminiyam ibe ngumqhubi ophambili wokusebenza kwemali yenkqubo yokubuyisela kwakhona e-United States. Ingxelo yalo nyaka ikwazisa i-KPI entsha kraca, izinga lokujikeleza kwe-loop evaliweyo, elinganisa ipesenti yezinto ezisetyenzisiweyo ezisetyenzisiweyo ukubuyela kwimveliso efanayo - kulo mzekelo isikhongozeli sesiselo esitsha. Isishwankathelo sengxelo enamaphepha amabini siyafumanekaApha.

Ingxelo ikwabonisa ukuhla okuthobekileyo kwesiselo se-aluminiyam sinokuphinda sisetyenziswe umthengi kunyaka ophelileyo. Izinga lehlile ukusuka kwi-46.1 yeepesenti ngo-2019 ukuya kwi-45.2 yeepesenti ngo-2020 phakathi kobhubhani we-COVID-19 kunye nolunye ukuphazamiseka kwintengiso. Nangona izinga lokuhla, inani leetoti zesiselo ezisetyenzisiweyo (UBC) ezisetyenzisiweyo ngokutsha lishishini linyuke nge-4 yeebhiliyoni zeetoti ukuya kwi-46.7 yeebhiliyoni zeetoti ngo-2020. Ireyithi nangona kunjalo yehla phakathi kokukhula kweetoti zokuthengisa kunyaka ophelileyo. Umyinge weminyaka engama-20 wezinga lokuphinda usetyenziswe ngabathengi limalunga nama-50 epesenti.

Umbutho weAluminiyam uxhasa iumzamo ndlongoibhengezwe ngaphambili yi-CMI ukunyusa i-aluminiyam inokuphinda isetyenziswe kwi-recycling kumashumi eminyaka ezayo ukusuka kwinqanaba lanamhlanje le-45.2 ekhulwini ukuya kuma-70 ekhulwini ngo-2030; Ipesenti ezingama-80 ngo-2040 kunye nama-90 ekhulwini ngo-2050. Umbutho uya kusebenza ngokusondeleyo ne-CMI kunye neenkampani zethu ezingamalungu kumzamo obanzi, weminyaka emininzi wokwandisa i-aluminium inokubuyisela amaxabiso ngokutyhala ekudaleniIinkqubo zediphozithi eziyilwe kakuhle, phakathi kwamanye amanyathelo.

"Iitoti ze-Aluminiyam zihlala zisesona sikhongozeli sesiselo esisetyenzisiweyo kunye nesinokuphinda sisetyenziswe kwimarike namhlanje," utshilo uRaphael Thevenin, usekela-mongameli wezokuthengisa kunye nokuthengisa kwiConstellium kunye nosihlalo weKomiti yeAluminiyam yeCan Sheet Producers Committee. "Kodwa izinga lokuphinda lisetyenziswe e-US kwiitoti lisemva kwehlabathi liphela - ukutsalwa ngokungeyomfuneko kokusingqongileyo kunye noqoqosho. Ezi thagethi zintsha zase-US zokurisayikilisha ziya kuvuselela isenzo ngaphakathi nangaphandle kweshishini ukubuyisela iinkonkxa ezininzi kumjelo wokurisayikilisha.

"I-CMI iyaziqhenya ngokuba isiselo se-aluminium sinokuqhubeka sidlula abakhuphisana nabo kwiimetriki eziphambili zokuzinza," kusho uRobert Budway, umongameli we-CMI. “Isiselo se-CMI singenza umenzi kunye ne-aluminiyam ishicilele amalungu ababoneleli bazibophelele ekwakhiweni kokusebenza okuphezulu kozinzo lwetoti yesiselo kwaye babonakalise ukuzinikela ekujoliswe kuko kushishino olutsha lwezinga lokurisayikilisha. Ukuphumeza olu sukelo akubalulekanga nje ekukhuleni kolu shishino, kodwa kuya kunceda indalo noqoqosho.”

Izinga lokujikeleza kwe-loop evaliweyo, i-KPI entsha eyaziswa kulo nyaka, ilinganisa ipesenti yezinto ezisetyenzisiweyo ezisetyenziselwa ukubuyela kwimveliso efanayo - kulo mzekelo isitya esitsha sesiselo. Iyinxalenye yomlinganiselo womgangatho wokurisayikilisha. Xa iimveliso ziresayikilishwa, imathiriyeli efunyenweyo ingasetyenziselwa ukwenza okufanayo (i-loop-loop recycling) okanye imveliso eyahlukileyo ngamanye amaxesha yomgangatho ophantsi (i-open-loop recycling). Ukurisayikilishwa kwe-loop evaliweyo kuyakhethwa kuba ngokwesiqhelo imveliso esetyenzisiweyo igcina umgangatho ofanayo kunye nemathiriyeli yokuqala kwaye inkqubo inokuphinda iphindwe kaninzi. Ngokwahlukileyo, ukuphinda kusetyenziswe i-loop evulekileyo kunokukhokelela kumgangatho wemathiriyeli osengozini ngotshintsho kwikhemistri okanye ukonyuka kokungcoliseka kwimveliso entsha.

Ezinye iziphumo eziphambili kwingxelo ka-2021 ziquka:

• Izinga lokurisayikilishwa kweshishini, eliquka ukurisayikilishwa kwazo zonke izikhongozeli zeziselo ezisetyenzisiweyo ze-aluminiyam (UBCs) lishishini lase-US (kubandakanywa nee-UBC ezithunyelwa ngaphandle nezithunyelwa ngaphandle) linyuke laya kutsho kwi-59.7 yeepesenti, ukusuka kwi-55.9 yeepesenti ngo-2019. Olu tshintsho luqhutywe kakhulu kukunyuka okubalulekileyo kwi-UBC ethumela ngaphandle ngo-2020, echaphazela inani lokugqibela.
• Izinga lesetyhula evaliweyo yeetoti ze-aluminium (echazwe ngasentla) yayiyi-92.6 yeepesenti xa kuthelekiswa neepesenti ze-26.8 zeebhotile ze-PET kunye naphakathi kwe-30-60 yeepesenti kwiibhotile zeglasi.
• Umndilili ohlaziyiweyo we-aluminiyam unokuma kwiipesenti ezingama-73, ungaphezulu lee kwiintlobo zokupakishwa ezikhuphisanayo.
• I-aluminiyam ingahlala iyeyona phakheji yesiselo ixabisekileyo kumgqomo wokurisayikilisha, enexabiso le-991/toni xa kuthelekiswa ne-$205/toni ye-PET kunye nexabiso elibi le-$23/toni yeglasi, ngokusekelwe kumyinge weminyaka emibini yokuqengqeleka. NgoFebruwari 2021. Amaxabiso e-aluminiyam ehle kakhulu ngexesha lokuqala lobhubhani we-COVID-19 kodwa ukusukela oko achacha ngokumangalisayo.

Ukunyusa isiselo se-aluminiyam kunokwenza iireyithi zokurisayikilisha ziya kuba nefuthe elikhulu kuzinzo olupheleleyo lweshishini lasekhaya le-aluminiyam. Ekuqaleni kwalo nyaka, umbutho wakhupha entsha,ingxelo yovavanyo lomjikelo wobomi bomntu wesithathu (LCA).ebonisa ukuba i-carbon footprint yeetoti ze-aluminium ezenziwe kuMntla Melika yehle malunga nesiqingatha kwiminyaka engamashumi amathathu edlulileyo. I-LCA iphinde yafumanisa ukuba ukurisayikilisha enye kunokonga i-1.56 megajoules (MJ) yamandla okanye i-98.7 grams yeCO.₂ngokulinganayo. Oku kuthetha ukuba ukurisayikilisha nje ipakethi ye-12 yeetoti ze-aluminiyam kuya konga amandla awoneleyoamandla imoto yomkhweli eqhelekileyomalunga neemayile ezintathu. Amandla agcinwe ngokurisayikilisha iinkonkxa zesiselo ze-aluminiyam ngoku eziya kwiindawo zokulahla inkunkuma zase-US ngonyaka ngamnye anokonga malunga ne-800 yezigidi zeerandi kuqoqosho kunye namandla aneleyo ukunika amandla ngaphezulu kwe-2 yezigidi zezindlu unyaka opheleleyo.
