Urhulumente wephondo laseVale nasePala ubambe umbhiyozo ngomhla wesi-6 ku-Epreli ukubhiyozela ukuqala kokwakhiwa kwesityalo sokuqala sokusebenza kwezorhwebo esichwepheshileyo eMalaba, isixeko esikumzantsi-mpuma wephondo lasePala, eBrazil. I-Tecnored, ubuchwepheshe obutsha, inokunceda ishishini lesinyithi nentsimbi ukuba lisuse i-carbon ngokusebenzisa i-biomass endaweni yamalahle esinyithi ukuvelisa isinyithi sehagu eluhlaza kunye nokunciphisa ukukhutshwa kwekhabhoni ukuya kuthi ga kwi-100%. Isinyithi sehagu singasetyenziselwa ukuvelisa isinyithi.
Umthamo wonyaka wemveliso yentsimbi eluhlaza yehagu kwisityalo esitsha uya kuqala ufikelele kwiitoni ezingama-250000, kwaye unokufikelela kwiitoni ezingama-500000 kwixesha elizayo. Esi sityalo sicwangciselwe ukuqaliswa ukusebenza ngo-2025, kunye notyalo-mali oluqikelelwa kwi-1.6 yeebhiliyoni zeerais.
“Ukwakhiwa kwesityalo sokusebenza sorhwebo esisekelwe kwitekhnoreyishini linyathelo elibalulekileyo ekuguquleni imboni yezemigodi. Kuya kunceda uthotho lweenkqubo ukuba luzinze ngakumbi nangakumbi. Iprojekthi yeTeknoreyishini ibaluleke kakhulu kwiVale nakwingingqi apho iprojekthi ikhoyo. Iya kuphucula ukhuphiswano lwengingqi kwaye incede ummandla ufezekise uphuhliso oluzinzileyo.” U-Eduardo Bartolomeo, umphathi omkhulu weVale, utshilo.
Isityalo seekhemikhali zorhwebo seTecnored sikwindawo yokuqala yesityalo sentsimbi yehagu ikarajas kwindawo yemizi-mveliso yaseMalaba. Ngokwenkqubela phambili yeprojekthi kunye nophando lobunjineli, kulindeleke ukuba kudalwe imisebenzi engama-2000 kwixesha eliphezulu leprojekthi kwinqanaba lokwakha, kwaye imisebenzi engama-400 ethe ngqo nengathanga ngqo inokudalwa kwinqanaba lokusebenza.
Malunga neTekhnoloji yeTeknoloji
Isithando somlilo esifakwe kwi-tecnored sincinci kakhulu kunesithando somlilo esisetyenziswa kwi-blast, kwaye uluhlu lwaso lwezinto ezisetyenzisiweyo lunokuba lukhulu kakhulu, ukusuka kumgubo we-iron ore, i-slag yokwenza intsimbi ukuya kwi-slidge yedama le-ore.
Ngokuphathelele ipetroli, i-tenored furnace ingasebenzisa i-carbonized biomass, efana ne-bagasse kunye ne-Eucalyptus. Itekhnoloji ye-Tecnored yenza amafutha aluhlaza abe zii-compact (iibhloko ezincinci ezincinci), ize iwafake kwi-furnace ukuvelisa i-pig iron eluhlaza. Ii-Tecnored furnace zingasebenzisa namalahle e-metallurgical njenge-fuel. Ekubeni itekhnoloji ye-tecnored isetyenziselwa ukusebenza okukhulu okokuqala, amafutha e-fossil aza kusetyenziswa ekusebenzeni kokuqala kwesityalo esitsha ukuze kuvavanywe ukusebenza komsebenzi.
“Siza kuthatha indawo yamalahle kancinci kancinci nge-carbonized biomass de sifikelele kwinjongo yokusebenzisa i-biomass nge-100%.” UMnu. Leonardo Caputo, i-CEO ye-tecnored, utshilo. Ukuguquguquka ekukhetheni amafutha kuya kunciphisa iindleko zokusebenza ze-tecnored ukuya kuthi ga kwi-15% xa kuthelekiswa nezitofu zemveli zokuqhumisa.
Itekhnoloji yeTecnored iye yaphuhliswa kangangeminyaka engama-35. Iyasusa amakhonkco okucola kunye nokusila kwisigaba sokuqala sokuveliswa kwentsimbi, zombini ezikhupha inani elikhulu leegesi ezibangela ubushushu.
Ekubeni ukusetyenziswa kwesithando somlilo esilungisiweyo kungadingi ukucolwa nokusilwa, utyalo-mali lwesityalo saseXingang lunokonga ukuya kuthi ga kwi-15%. Ukongeza, isityalo esilungisiweyo sinokuzimela ngokwaso ekusebenziseni amandla kakuhle, kwaye zonke iigesi eziveliswa kwinkqubo yokunyibilikisa ziphinda zisetyenziswe, ezinye zazo zisetyenziselwa ukuvelisa izinto ezifanayo. Ingasetyenziswa kungekuphela nje njengezinto eziluhlaza kwinkqubo yokunyibilikisa, kodwa nakwimveliso engaphantsi kwishishini lesamente.
Okwangoku iVale inesityalo sokubonisa esinomthamo weetoni ezingama-75000 ngonyaka ePindamoniyangaba, eSao Paulo, eBrazil. Le nkampani iqhuba uphuhliso lobuchwephesha kwisityalo kwaye ivavanya ukuba sinokwenzeka na kwezobuchwepheshe nangokwezoqoqosho.
Ukunciphisa ukukhutshwa komoya "kwiScope III"
Ukusebenza kwezorhwebo kwesityalo esichwetheziweyo eMalaba kubonisa imizamo yeVale yokubonelela ngezisombululo zobugcisa kubathengi besityalo sentsimbi ukubanceda basuse i-carbon kwinkqubo yabo yemveliso.
Ngowama-2020, iVale yabhengeza injongo yokunciphisa ukukhutshwa kwe-“scope III” nge-15% ngo-2035, apho ukuya kuthi ga kwi-25% kuya kufezekiswa ngepotifoliyo yemveliso esemgangathweni ophezulu kunye neenkqubo zobuchwepheshe ezintsha kuquka ukunyibilikisa intsimbi yehagu eluhlaza. Ukukhutshwa kwegesi okuvela kushishino lwentsimbi ngoku kumalunga ne-94% yokukhutshwa kwegesi “scope III” eVale.
IVale ikwabhengeze enye injongo yokunciphisa ukukhutshwa komoya, oko kukuthi, ukufezekisa ukukhutshwa komoya ngokuthe ngqo nangokungathanga ngqo ("i-scope I" kunye ne-"scope II") ngo-2050. Le nkampani iza kutyala imali eyi-US $4 yeebhiliyoni ukuya kwi-US $6 yeebhiliyoni kwaye yonyuse indawo yamahlathi ebuyiselweyo nekhuselweyo ngeehektare ezingama-500000 eBrazil. IVale ibisebenza kwiphondo lasePala iminyaka engaphezu kwama-40. Le nkampani ibisoloko ixhasa i-chicomendez Institute for biodiversity conservation (icmbio) ukukhusela iindawo zokugcina izityalo ezintandathu kummandla weKaragas, ezibizwa ngokuba yi-"karagas mosaic". Zigubungela iihektare ezingama-800000 zehlathi laseAmazon, eliphindwe kahlanu indawo yaseSao Paulo kwaye lilingana neWuhan eTshayina.
