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 ziqulethe naphi na ukusuka kwi-3X ukuya kwi-20X engaphezulu komxholo osetyenzisiweyo kuneglasi okanye iibhotile ze-PET kwaye zixabiseke kakhulu njenge-scrap, okwenza i-aluminium ibe ngumqhubi oyintloko we-financial viability ye-recycling system e-United States.Ingxelo yalo nyaka ikwazisa i-KPI entsha kraca, izinga lokujikeleza kwe-loop evaliweyo, elilinganisa 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 lonyuke nge-4 yeebhiliyoni zeetoti ukuya kwi-46.7 yeebhiliyoni zeetoti ngowama-2020.Umyinge weminyaka engama-20 kwireyithi yokurisayikilisha abathengi umalunga nama-50 epesenti.

Umbutho weAluminiyam uxhasa iumzamo ndlongoibhengezwe ngaphambili yi-CMI ukunyusa izinga le-aluminiyam inokuphinda isetyenziswe kumashumi eminyaka ezayo ukusuka kwinqanaba lanamhlanje leepesenti ezingama-45.2 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 wokunyusa i-aluminium inokubuyisela amaxabiso ngokutyhala ekudalweniIinkqubo zediphozithi eziyilwe kakuhle, phakathi kwamanye amanyathelo.

"Iitoti ze-Aluminiyam zihlala zisesona sitya sesiselo esisetyenzisiweyo kunye nesinokuphinda sisetyenziswe kwimarike namhlanje," watsho uRaphael Thevenin, usekela-mongameli wezokuthengisa kunye nokuthengisa kwi-Constellium kunye nosihlalo weKomiti ye-Aluminium Association's Can 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 sigqithisa abakhuphisana nabo kwiimetriki eziphambili zokuzinza," kusho uRobert Budway, umongameli we-CMI.“Isiselo se-CMI singenza umenzi kunye ne-aluminiyam ingashicilela 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 kuxhamlisa okusingqongileyo 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 imveliso iphinda isetyenziswe, 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-phindwa kwakhona.Ngokwahlukileyo, ukuphinda kusetyenziswe i-loop evulekileyo kunokukhokelela kumgangatho wezinto eziphathekayo ngokutshintsha kwekhemistri 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 ixabiseke kakhulu kumgqomo wokurisayikilisha, enexabiso le-991/itoni 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.

Ukonyuka kwesiselo se-aluminiyam kunokwenza amaxabiso okurisayikilisha kuya kuba nempembelelo enkulu 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 kule minyaka ingamashumi amathathu idlulileyo.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 angaphezu kwezigidi ezi-2 zezindlu unyaka wonke.
