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 nemakwikwi ekurongedza emhando. Chirevo ichi chinogadziridza akati wandei makiyi ekuita zviratidzo (KPI) ye2020 uye inoona kuti vatengi vanodzoreredza magaba ealuminium pane zvakapetwa kaviri chiyero chepurasitiki (PET) mabhodhoro. 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 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, huwandu hwemagaba ezvinwiwa akashandiswa (UBC) akashandiswazve neindasitiri akawedzera nemagaba anosvika 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 ne2030; 80 muzana ne2040 uye 90 muzana ne2050. Sangano richashanda pamwe chete neCMI nemakambani edu nhengo pakuedza kwakazara, kwemakore akawanda kuwedzera aruminiyamu inogona kudzokorodza mitengo nekusundira kuti kusikwa kweyakanyatsogadzirwa mudziyo dhipoziti masisitimu, pakati pezvimwe zviyero.

“Magaba eAluminium anoramba ari chigadziko chezvinwiwa chakanyanya kushandiswazve uye chinodzokororwa pamusika nhasi,” akadaro Raphael Thevenin, mutevedzeri wapurezidhendi wekutengesa nekutengesa kuConstellium uye sachigaro weAluminium Association's Can Sheet Producers Committee. "Asi mwero weUS wekudzokorodza wemagaba unosaririra kuseri kwepasirese - kukweva kusingakodzeri kwezvakatipoteredza nehupfumi. Izvi zvitsva zveUS recycling rate tarisiro zvinokonzeresa chiito mukati nekunze kweindasitiri kuunza mamwe magaba 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 chekusimudzira kuita kwepamusoro uye vakaratidza kuzvipira ikoko nezvinangwa zvitsva zveindasitiri. Kuzadzikiswa kwezvinangwa izvi hakuna kukosha chete mukukura kweindasitiri, asi kunobatsira nharaunda nehupfumi.”

Iyo yakavharwa-loop circularity rate, iyo KPI nyowani yakaunzwa gore rino, inoyera iyo muzana yezvinhu zvakadzokororwa zvakashandiswa kudzoka muchigadzirwa chimwe chete - mune iyi kesi mudziyo mutsva wekunwa. Icho chikamu chechiyero chemhando yekudzokorodza. Kana zvigadzirwa zvadzokororwa, izvo zvakadzoserwa zvinogona kushandiswa kugadzira zvakafanana (yakavharwa-loop recycling) kana chimwe 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) neindasitiri US (kusanganisira kunze uye kunze UBCs kunze) wakakwira kusvika 59.7 muzana, kubva 55.9 muzana muna 2019. Shanduko iyi yakakonzerwa zvikuru nekuwedzera kukuru. muUBC inotengeswa kunze kwenyika muna 2020, iyo inokanganisa nhamba yekupedzisira.
• Iyo yakavharwa-loop circularity rate yemagaba ealuminium (yakatsanangurwa 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 iri chinwiwa chakanyanya 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 nemhedzisiro yakakura pakusimba kwese kweiyo indasitiri yemumba yealuminium. Kutanga kwegore rino, sangano rakaburitsa idzva,yechitatu-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 kudzokorodza chete gumi nemaviri-pack yemagaba ealuminium inochengetedza simba rakakwana kunesimbisa mota yevafambikwemaira anenge matatu. Simba rinochengetwa nekudzoreredza magaba echinwiwa ealuminium anoenda kuUS gore rega rega anogona kuchengetedza mari inosvika madhora mazana masere emamiriyoni ehupfumi uye simba rakakwana rekugonesa dzimba dzinopfuura mamirioni maviri kwegore rose.
