Zvakanaka, maererano neshumo ichangobva kuitika kuburikidza neAluminium AssociationuyeInogona Manufacturers Institute(CMI) -Iyo Aluminium Inogona Kubatsira: Sustainability Key Performance Indicators 2021-Kuratidza kuenderera mberi kwemabhenefiti echinwiwa chealuminium chigadziko kana chichienzaniswa neanokwikwidza marudzi ekurongedza.Chirevo ichi chinogadziridza akati wandei makiyi ekuita zviratidzo (KPI) ye2020 uye inoona kuti vatengi vanodzoreredza magaba ealuminium pane inodarika kaviri mwero wemabhodhoro epurasitiki (PET).Aluminium zvinwiwa magaba anewo chero kubva ku3X kusvika 20X zvimwe zvakadzokororwa zvirimo kupfuura girazi kana mabhodhoro ePET uye akakosha zvakanyanya sezvimedu, zvichiita kuti aruminiyamu mutyairi akakosha wekugonesa kwemari kweiyo recycling system muUnited States.Chirevo chegore rino chinosumawo mhando-nyowani yeKPI, iyo yakavharwa-loop circularity rate, iyo inoyera iyo muzana yezvinhu zvakadzokororwa zvakashandiswa kudzokera muchigadzirwa chimwe chete - mune iyi chigadziko chitsva chekunwa.Pfupiso yemushumo wemapeji maviri inowanikwahere.

Chirevo ichi chinoratidzawo kudzikira kwakadzikama kwechinwiwa chealuminium chinogona kudzokorodza mutengi gore rapfuura.Huwandu hwakadzikira kubva pa46.1 muzana muna 2019 kusvika 45.2 muzana muna 2020 mukati meiyo COVID-19 denda uye kumwe kukanganisa mumusika.Pasinei nekuderera kwehuwandu, nhamba yemagaba ezvinwiwa akashandiswa (UBC) akashandiswazve neindasitiri yakawedzera nemagaba angangoita mabhiriyoni mana kusvika kumagaba mabhiriyoni 46,7 muna 2020. Chiyero chacho chakaderera pakati pekukura kwekutengesa kwegore rapfuura.Avhareji yemakore makumi maviri yehuwandu hwekudzokorodza kwevatengi inosvika makumi mashanu muzana.

Iyo Aluminium Association iri kutsigirakuedza kwehashayakaziviswa kare neCMI kuti iwedzere aluminium inogona kudzoreredza mitengo pamakumi emakore anouya kubva padanho ranhasi re45.2 muzana kusvika 70 muzana panosvika 2030;80 muzana ne2040 uye 90 muzana ne2050. Sangano richashanda pamwe chete neCMI nemakambani edu nhengo pakuedza kwakazara, kwemakore akawanda kuwedzera aluminium inogona kudzokorodza mitengo kuburikidza nekumanikidzira kuti kusikwa kweyakanyatsogadzirwa mudziyo dhipoziti masisitimu, pakati pezvimwe zviyero.

"Magaba eAluminium anoramba ari chigadziko chezvinwiwa chakanyanya kushandiswa pamusika nhasi," akadaro Raphael Thevenin, mutevedzeri wemutungamiri wekutengesa nekushambadzira kuConstellium uye sachigaro weAluminium Association's Can Sheet Producers Committee."Asi mwero wekudzokorodza kweMagaba weUS unosaririra kuseri kwepasirese - kukweva kusingakodzere nharaunda nehupfumi.Izvi zvitsva zveUS recycling rate tarisiro zvinokonzeresa chiito mukati nekunze kweindasitiri kuunza mamwe magaba kumashure murukova rwekudzokorodza. "

"CMI inodada kuti chinwiwa chealuminium chinogona kuramba chichipfuura vakwikwidzi vayo pamametric akakosha ekuchengetedza," akadaro Robert Budway, purezidhendi weCMI."CMI chinwiwa chinogona kugadzira uye aruminiyamu inogona kusheedzera nhengo dzevanopa vakazvipira kuvaka pamusoro pechinwiwa chepamusoro uye vakaratidza kuzvipira ikoko nezvinangwa zveindasitiri zvekudzokorodza zvakare.Kuzadzikisa zvinangwa izvi hakuna kukosha chete mukukura kweindasitiri, asi kunobatsirawo nharaunda nehupfumi hwenyika.”

Iyo yakavharwa-loop circularity rate, iyo KPI nyowani yakaunzwa gore rino, inoyera iyo muzana yezvinhu zvakadzokororwa zvakashandiswa kudzokera muchigadzirwa chimwe chete - mune iyi chigadziko chinwiwa chitsva.Icho chikamu chechiyero chemhando yekudzokorodza.Kana zvigadzirwa zvadzokororwa, izvo zvakadzoserwa zvinogona kushandiswa kugadzira zvakafanana (yakavharwa-loop recycling) kana chakasiyana uye dzimwe nguva chakaderera giredhi chigadzirwa (yakavhurika-loop recycling).Yakavharwa-loop recycling inosarudzwa nekuti kazhinji chigadzirwa chakadzokororwa chinochengeta mhando yakafanana neyekutanga zvinhu uye maitiro anogona kudzokororwa kakawanda.Kusiyana neizvi, kuvhurika-loop kudzokorodza kunogona kutungamira kune yakakanganisika yemhando yemhando kuburikidza nekuchinja kwekemikari kana kuwedzera kusvibiswa muchigadzirwa chitsva.

Zvimwe zvakakosha zvakawanikwa mumushumo wa2021 zvinosanganisira:

• The indasitiri recycling mwero, izvo zvinosanganisira kudzokororwa ose aruminiyamu kushandiswa zvinwiwa midziyo (UBCs) neveUS indasitiri (kusanganisira ekunze uye kunze UBCs) yakakwira kusvika 59.7 muzana, kubva 55.9 muzana muna 2019. Shanduko iyi yakakonzerwa zvikuru nekuwedzera kukuru. muUBC inotengeswa kunze kwenyika muna 2020, izvo zvinokanganisa nhamba yekupedzisira.
• Iyo yakavharwa-loop circularity rate yemagaba ealuminium (inotsanangurwa pamusoro) yaive 92.6 muzana kana ichienzaniswa ne26.8 muzana yemabhodhoro ePET uye pakati pe30-60 muzana yemabhodhoro egirazi.
• Avhareji yakadzokororwa zvemukati zvealuminium inogona kumira pa73 muzana, inodarika nekure emakwikwi ekurongedza marudzi.
• Aluminium inogona kuramba ichinyanya kukosha mubhini rekudzokorodza, ine kukosha kwe $991/tani zvichienzaniswa ne$205/ton yePET uye kukosha kwakashata kwe$23/tani yegirazi, zvichibva paavhareji yemakore maviri Kukadzi 2021. Aluminium scrap values ​​yakadzikira zvakanyanya panguva yekutanga kweCCIDID-19 denda asi kubva ipapo yapora zvakanyanya.

Kuwedzera aruminiyamu chinwiwa kunogona kudzokorodza mareti kuchave nekukanganisa kukuru pakusimba kwese kweindasitiri yealuminium indasitiri.Kutanga kwegore rino, sangano rakaburitsa idzva,wechitatu-bato rehupenyu kutenderera ongororo (LCA) mushumozvichiratidza kuti carbon footprint yemagaba ealuminium akagadzirwa kuNorth America yakaderera neinoda kusvika hafu mumakore makumi matatu apfuura.Iyo LCA yakaona zvakare kuti kudzokorodza imwe chete kunogona kuchengetedza 1.56 megajoules (MJ) yesimba kana 98.7 magiramu eCO.₂yakaenzana.Izvi zvinoreva kuti kudzokorodzazve gumi nemaviri-pack yemagaba ealuminium kunochengetedza simba rakakwana kunesimbisa mota yevafambikwemaira anenge matatu.Simba rakachengetwa nekudzoreredza magaba echinwiwa ealuminium anoenda kuUS gore rega rega anogona kuchengetedza madhora mazana masere emamiriyoni ehupfumi uye simba rakakwana rekugonesa dzimba dzinopfuura mamiriyoni maviri kwegore rose.
