Hurumende yeVale nePala yakaita mhemberero musi wa6 Kubvumbi yekupemberera kutanga kwekuvakwa kwefekitori yekutanga yekutengeserana yakatekishwa muMalaba, guta riri kumaodzanyemba kwakadziva kumabvazuva kwedunhu rePala, Brazil. Tecnored, tekinoroji itsva, inogona kubatsira indasitiri yesimbi nesimbi kubvisa kabhoni nekushandisa biomass panzvimbo pemarasha esimbi kugadzira simbi yenguruve yakasvibirira uye kuderedza kuburitswa kwekabhoni kusvika ku100%. Simbi yenguruve inogona kushandiswa kugadzira simbi.
Kugona kwekugadzira simbi yegirini pagore mufekitori itsva kuchatanga kusvika matani 250000, uye kunogona kusvika matani 500000 mune ramangwana. Fekitori iyi yakarongerwa kutanga kushanda muna 2025, iine mari inofungidzirwa inosvika mabhiriyoni 1.6 reais.
"Kuvakwa kwefekitori yekutengeserana yakacheneswa idanho rakakosha mukushandura indasitiri yemigodhi. Izvi zvichabatsira kuti cheni yemabasa irambe ichienderera mberi. Purojekiti yeTecnored inokosha zvikuru kuVale nedunhu riripo. Izvi zvichavandudza kukwikwidzana kwedunhu uye zvichabatsira dunhu kuwana budiriro inoenderera mberi." Eduardo Bartolomeo, mukuru weVale, akadaro.
Chivako chemakemikari cheTecnored commercial chiri panzvimbo yekutanga yekambani yesimbi yenguruve yeKarajas muMalaba industrial zone. Zvichienderana nekufambira mberi kweprojekiti uye tsvakiridzo yeinjiniya, mabasa 2000 anotarisirwa kugadzirwa munguva yepamusoro yeprojekiti iri padanho rekuvaka, uye mabasa 400 akananga uye asina kunanga anogona kugadzirwa panguva yekushanda.
Nezve tekinoroji yetekinoroji
Furnace yakagadzirwa netecnored idiki zvikuru pane furnace yechinyakare yeblast, uye mhando dzayo dzezvinhu zvinogona kuva dzakakura zvikuru, kubva paupfu hwesimbi, slag yekugadzira simbi kusvika kumatope edhamu reore.
Panyaya yemafuta, tanuru yakacheneswa inogona kushandisa biomass yakakangwa, senge masagasse neEucalyptus. Tekinoroji yeTecnored inogadzira mafuta asina kugadzirwa kuita macompact (zvidimbu zvidiki), uye yozoaisa mutanuru kuti igadzire simbi yenguruve yakasvibirira. Matanuru eTecnored anogonawo kushandisa marasha esimbi semafuta. Sezvo tekinoroji yeTecnored ichishandiswa pakushanda kukuru kekutanga, mafuta efossil achashandiswa pakutanga kwekushanda kwefekitari itsva kuitira kuongorora mashandiro ekushanda.
"Tichatsiva marasha zvishoma nezvishoma necarbonized biomass kusvika tasvika pachinangwa chekushandisa biomass 100%." ​​VaLeonardo Caputo, CEO wetecnored, vakadaro. Kuchinjika pakusarudza mafuta kuchaderedza mari yekushanda kwetecnored kusvika ku15% kana tichienzanisa nemidziyo yemazuva ano yekupisa.
Tekinoroji yeTecnored yave ichigadzirwa kwemakore makumi matatu nemashanu. Inobvisa zvinobatanidza coking uye sintering pakutanga kwekugadzirwa kwesimbi, zvese izvi zvinoburitsa magasi akawanda egreenhouse.
Sezvo kushandiswa kwechoto chakagadziriswa hakudi kupiswa nekupiswa, mari inoshandiswa nefekitori yeXingang inogona kuchengetedza kusvika ku15%. Pamusoro pezvo, fekitori yakagadziriswa inozvishandira yega mukushandisa simba zvakanaka, uye magasi ese anogadzirwa mukugadzirwa kwekunyungudutsa anoshandiswazve, mamwe acho anoshandiswa kugadzira pamwe chete. Inogona kushandiswa kwete chete sezvinhu zvisina kugadzirwa mukugadzirwa kwekunyungudutsa, asiwo sezvinhu zvinobva muindasitiri yesimende.
Parizvino Vale ine fekitari yekuratidzira ine huremu hwematani 75000 pagore mupindamoniyangaba, Sao Paulo, Brazil. Kambani iyi inoita hunyanzvi hwekugadzira fekitari iyi uye inoedza kugona kwayo hunyanzvi uye hupfumi.
Kuderedzwa kwe "Scope III"
Kushanda kwefekitori yetecnored muMalaba kunoratidza kuedza kweVale kupa mhinduro dzehunyanzvi kune vatengi vefekitori yesimbi kuti ivabatsire kubvisa kabhoni mukugadzirwa kwavo.
Muna 2020, Vale yakazivisa chinangwa chekuderedza kuburitswa kwe "scope III" ne15% panosvika 2035, izvo zvinosvika 25% zvichawanikwa kuburikidza nezvigadzirwa zvepamusoro-soro uye zvirongwa zvetekinoroji zvinosanganisira kunyungudutsa simbi yenguruve yakasvibirira. Kuburitswa kwemhepo kubva muindasitiri yesimbi parizvino ndiko kunoita 94% ye "scope III" yeVale.
Vale yakazivisawo chimwe chinangwa chekudzikisa utsi, ndiko kuti, kuwana hutsi hwakananga uye husina kunanga ("scope I" uye "scope II") panosvika 2050. Kambani iyi ichaisa US $4 bhiriyoni kusvika US $6 bhiriyoni uye ichawedzera nzvimbo yemasango yakadzorerwa uye yakachengetedzwa nemahekita 500000 muBrazil. Vale yave ichishanda mudunhu rePala kwemakore anopfuura 40. Kambani iyi yagara ichitsigira chicomendez Institute for biodiversity conservation (icmbio) kuchengetedza nzvimbo nhanhatu dziri mudunhu reKaragas, dzinonzi "karagas mosaic". Dzinofukidza mahekita 800000 esango reAmazon, rinova nzvimbo yeSao Paulo kashanu uye yakaenzana neWuhan muChina.
