Ukusetyenziswa kwe imihlaba esecaleni yokulima ezinye zezityalo eziza kunikezelwa ngokukodwa kwi imveliso ezinzileyo ye-biomass.
Ngezimvo ezininzi ezahlukeneyo zokutyala izityalo ukuze zisetyenziswe i-bioenergy ezinzileyo ukubanakho ukusebenzisa ezi hektare ukuze zisetyenziswe ukutya kwezolimo, ngokuvunywa kwamanyathelo olawulo, i-European Union iyazenza ukunciphisa ukusetyenziswa kolu hlobo lokugqibela lwesityalo (ukutya kwezolimo) kwaye ke ngoko bakwazi ukuwuthwala ngokusebenzisa umhlaba ohluke ngokupheleleyo kwimveliso ye-bioenergy.
Ukuncedisa emva kokunyusa okwenziweyo kwimveliso ye-biofuels ezinzileyo kunye ne-lignocellulosic biomass enje ingcongolo eqhelekileyo okanye i-panizo yethafa.
Umphandi UDolores Curt weqela le-GA-UPM Ukugcina oko " Ityuwa emhlabeni okanye ekunkcenkcesheleni sisithintelo kwizityalo ezininzi zezolimo, kodwa inokuba lithuba lokuvelisa i-biomass engakhuphisaniyo necandelo lokutya kwezolimo kwaye ngaloo ndlela iphucule ukuzinza kwayo. Iswekile eqhelekileyo sisityalo esinamandla amelana netyuwa kwaye sixhaswa yi-European Union. Kuzo zonke ezi zizathu, kubalulekile ukwazi apho inokukhuthazwa khona kwaye imveliso yayo izakumela ntoni ”.
Njengoko lo mphengululi egqabaza, Ityiwa yinto ebaluleke kakhulu (Zininzi izinto zolu hlobo) ekufuneka uzithathele ingqalelo xa usenza umhlaba ukulungele ukutya kwezolimo ukusukela oko Ityuwa ichaphazela ukukhula ngokuthe ngqo nangokungathanga ngqo kwezityaloKungenxa yomonakalo obangelwe yityuwa okanye ngenxa yokuncipha kokufunxwa kwamanzi ziingcambu, into ebalulekileyo ukuze izityalo ziqhubeke ziphila.
Ngesi sizathu sinye kwaye ukuze izityalo zokutya kwezolimo (ezinemveliso ephantsi) okanye imihlaba elahliweyo ingaphelelwa, bakhetha ukusebenzisa le mihlaba isezantsi, imihlaba enetyuwa, ukulima iintlobo ezithile zezityalo ezinganyangekiyo okanye mandithi, ukunyamezelana nobutyuwa.
Umzekelo ocacileyo kunye nokuvuselela umdla wabaphandi abaninzi kule ndawo ku ingcongolo eqhelekileyo Kuba ayinyamezeli ityuwa kuphela, kodwa ikwayimifuno engapheliyo (isityalo esingengomthi esikwaziyo ukuhlala ngaphezulu kweminyaka emibini), iyaziguqula iimeko ze-edaphoclimatic, Oko kukuthi, iimeko eziphathelene nomhlaba kunye nemozulu.
Ikwasinika imveliso ephezulu ngokwentengiso yonyaka ye-lignocellulosic biomass ithatha ukuba.
Ngale njongo, abaphandi be-GA-UPM baphuhlise indlela ethile yokuqikelela imveliso ye-biomass enokuthi ibandakanye ukusetyenziswa kwemihlaba enetyuwa esezantsi kunye nemihlaba ebekelwe bucala enokunkcenkceshela ngamanzi anetyuwa, ukwenzela ukuveliswa kwebhayomasi kunye nendwe eqhelekileyo.
Le ndlela yokusebenza iqulethe imisebenzi enomdla yokuphendula kubukho bamanzi kunye isivuno sendebe eqhelekileyo isetyiwa, Ukongeza ekufumaneni ulwazi oluchaziweyo nge-geo. Ukuthatha ingqalelo kumanqanaba ahlukeneyo ahluka-hlukeneyo etyuwa anokufumaneka kuloo mmandla kwaye ngokucacileyo emanzini okunkcenkceshela. Ukulandela kwakhona imigaqo yozinzo enokufunyanwa.
UJavier Sanchez, umbhali oyintloko womsebenzi, usixelela; "Le ndlela isetyenzisiwe kwilizwekazi laseSpain kodwa inokusetyenziswa nakwezinye iindawo zeMeditera ezinolwazi olufumanekayo ngokuma komhlaba", xa sifumana idatha emangalisa ngokwenene, kwaye kukuba ngokwamanani afunyenweyo siyabona ukuba ISpain ikufutshane Iihektare ezingama-34.500 zomhlaba wezolimo ubekelwe bucala yityuwa Apho kulinywa khona ummoba oqhelekileyo kuya kuba yinto elungileyo ekusebenziseni kakuhle le mihlaba kunye nokuzinza.
Ke ngoko, kunokwenzeka ukuba kubekho imveliso ye-biomass enokubakho yeetoni ezingama-597.400 zezinto ezomileyo ngonyaka, ngokubhekisele ekusebenzeni kombane ngama-25%, kunjalo nje, ukuba umhlali ngamnye usebenzisa i-730 KWh ngonyaka, enokuhambelana nesiseko Amandla ngonyaka malunga ne-10.5 yezigidi ze-gigajoules (GJ)
Ngombulelo kulo msebenzi kunye nomzamo weqela le-GA-UPM, iSpain inokuba nguvulindlela kwimveliso ye-biomass ezinzileyo ngokusebenzisa umhlaba oselunxwemeni olunetyuwa endaweni yokuba ibe neehektare ezingama-35.000 zomhlaba ezingakulungelanga ukulinywa kokutya kwezolimo.
