Uhulumeni wesifundazwe saseVale nasePala ubambe umgubho ngomhlaka-6 kuMbasa ukugubha ukuqala kokwakhiwa kwesitshalo sokuqala sokusebenza kwezentengiselwano esithengisiwe eMalaba, idolobha eliseningizimu-mpumalanga yesifundazwe sasePala, eBrazil. I-Tecnored, ubuchwepheshe obusha, ingasiza imboni yensimbi nensimbi ukuqeda i-carbon ngokusebenzisa i-biomass esikhundleni samalahle ensimbi ukukhiqiza insimbi yengulube eluhlaza nokunciphisa ukukhishwa kwekhabhoni ngamaphesenti afinyelela ku-100%. Insimbi yengulube ingasetshenziswa ukukhiqiza insimbi.
Umthamo wonyaka wokukhiqiza insimbi eluhlaza esitshalweni esisha uzoqala ufike kumathani angu-250000, futhi ungase ufike kumathani angu-500000 esikhathini esizayo. Lesi sitshalo sihlelwe ukuthi siqale ukusebenza ngo-2025, kanti kulinganiselwa ukuthi sizotshalwa imali engaba yizigidigidi ezingu-1.6 zama-reais.
"Ukwakhiwa kwesitshalo sokusebenza kwezentengiselwano esinobuchwepheshe kuyisinyathelo esibalulekile ekuguqulweni kwemboni yezimayini. Kuzosiza uchungechunge lwezinqubo ukuthi luqhubeke nokusimama. Iphrojekthi ye-Tecnored ibaluleke kakhulu e-vale kanye nesifunda lapho iphrojekthi ikhona khona. Izothuthukisa ukuncintisana kwesifunda futhi isize isifunda ukufeza intuthuko eqhubekayo." kusho u-Eduardo Bartolomeo, isikhulu esiphezulu saseVale.
Isitshalo samakhemikhali sezentengiselwano saseTecnored sitholakala endaweni yokuqala yesitshalo sensimbi se-karajas pig endaweni yezimboni yaseMalaba. Ngokusho kwenqubekela phambili yephrojekthi kanye nocwaningo lobunjiniyela, kulindeleke ukuthi kudalwe imisebenzi engu-2000 esikhathini esiphezulu sephrojekthi esigabeni sokwakha, kanti imisebenzi engu-400 eqondile nengaqondile ingadalwa esigabeni sokusebenza.
Mayelana nobuchwepheshe be-tecnored
Isithando somlilo se-Tecnored sincane kakhulu kunesithando somlilo sendabuko, futhi ububanzi baso bezinto zokusetshenziswa bungaba banzi kakhulu, kusukela kumpuphu we-iron ore, i-slag yokwenza insimbi kuya kudoti wedamu le-ore.
Ngokuphathelene nophethiloli, isithando somlilo esigoqiwe singasebenzisa i-biomass ekhabhoni, njenge-bagasse ne-Eucalyptus. Ubuchwepheshe be-Tecnored benza amafutha aluhlaza abe ama-compact (amabhlogo amancane aqinile), bese uwafaka esithandweni ukuze akhiqize insimbi yengulube eluhlaza. Ama-Tecnored angasebenzisa namalahle ensimbi njengophethiloli. Njengoba ubuchwepheshe be-tecnored busetshenziswa ekusebenzeni okukhulu okokuqala, amafutha emvelo azosetshenziswa ekusebenzeni kokuqala kwesitshalo esisha ukuze kuhlolwe ukusebenza komsebenzi.
“Kancane kancane sizofaka i-biomass e-carbonized esikhundleni samalahle kuze kube yilapho sifinyelela umgomo wokusetshenziswa kwe-biomass ngo-100%.” UMnu. Leonardo Caputo, i-CEO ye-tecnored, uthe. Ukuguquguquka ekukhetheni uphethiloli kuzonciphisa izindleko zokusebenza ze-tecnored ngamaphesenti afinyelela ku-15 uma kuqhathaniswa nezitofu zokuqhuma zendabuko.
Ubuchwepheshe be-Tecnored buthuthukiswe iminyaka engama-35. Buqeda izixhumanisi zokugaya nokukhipha insimbi esigabeni sokuqala sokukhiqizwa kwensimbi, zombili ezikhipha inani elikhulu lamagesi okushisa.
Njengoba ukusetshenziswa kwesithando somlilo esihlanganisiwe kungadingi ukucolwa nokushiswa, ukutshalwa kwezimali kwesitshalo i-Xingang kungonga kufika ku-15%. Ngaphezu kwalokho, isitshalo esihlanganisiwe sizimele ngokwaso ekusebenzeni kahle kwamandla, futhi wonke amagesi akhiqizwa enkambisweni yokuncibilikisa asetshenziswa kabusha, amanye awo asetshenziselwa ukukhiqiza ndawonye. Angasetshenziswa hhayi nje kuphela njengezinto zokusetshenziswa enkambisweni yokuncibilikisa, kodwa futhi njengomkhiqizo ongeziwe embonini yesimende.
I-Vale okwamanje inesitshalo sokukhombisa esinomthamo waminyaka yonke olinganiselwa kumathani angu-75000 e-pindamoniyangaba, eSao Paulo, eBrazil. Le nkampani yenza intuthuko yobuchwepheshe kulesi sitshalo futhi ihlola ukuthi kungenzeka yini ukukhiqiza ubuchwepheshe kanye nezomnotho.
Ukunciphisa ukukhishwa komoya “we-Scope III”
Ukusebenza kwezentengiselwano kwefektri ye-tecnored eMalaba kubonisa imizamo yeVale yokuhlinzeka ngezixazululo zobuchwepheshe kumakhasimende efektri yensimbi ukuze ibasize basuse i-carbon enkambisweni yabo yokukhiqiza.
Ngo-2020, iVale yamemezela umgomo wokunciphisa ukukhishwa kwe-“scope III” ngo-15% ngo-2035, okuzofinyelelwa kuwo kufikela ku-25% ngephothifoliyo yomkhiqizo esezingeni eliphezulu kanye nezinhlelo zobuchwepheshe obusha okuhlanganisa ukuncibilikisa insimbi eluhlaza okwesibhakabhaka. Ukukhishwa kwegesi okuvela embonini yensimbi okwamanje kungama-94% okukhishwa kwegesi “scope III” eVale.
UVale uphinde wamemezela omunye umgomo wokunciphisa ukukhishwa kwegesi, okungukuthi, ukufeza ukukhishwa kwegesi okuqondile nokungaqondile ("i-scope I" kanye ne-"scope II") ngo-2050. Le nkampani izotshala imali engu-$4 billion kuya ku-$6 billion futhi yandise indawo yehlathi evuselelwe futhi evikelwe ngamahektha angu-500000 eBrazil. UVale ubelokhu esebenza esifundazweni sasePala iminyaka engaphezu kwengu-40. Le nkampani ibilokhu isekela i-chicomendez Institute for biodiversity conservation (icmbio) ukuvikela izindawo zokugcina imvelo eziyisithupha esifundeni saseKaragas, ezibizwa ngokuthi "i-karagas mosaic". Zihlanganisa amahektha angu-800000 ehlathi lase-Amazon, eliphindwe kahlanu endaweni yaseSao Paulo futhi lilingana neWuhan eShayina.
