Ukusetshenziswa kwe izindawo eziseceleni ukuze kulinywe kuzo ezinye izitshalo ezizonikezelwa kuphela ku- ukukhiqizwa kwe-biomass okusimeme.
Ngemibono eminingi eyahlukahlukene yokutshala izitshalo ezizosetshenziswa ngu i-bioenergy eqhubekayo ukwazi ukusebenzisa lawo mahektha ukusetshenziswa kwe- izilimo zokudla kwezolimo, ngokuvunywa kwezinyathelo zokulawula, i-European Union iyazenzela ukunciphisa ukusetshenziswa kwalolu hlobo lokugcina lwesilimo (ukudla kwezolimo) futhi ngaleyo ndlela ikwazi ukukusebenzisa ngokusebenzisa umhlaba ohluke ngokuphelele ekukhiqizeni i-bioenergy.
Ukusiza ngokulandelana okwenziwayo ekukhiqizweni kwama-biofuels asimeme anama-lignocellulosic biomass afana umhlanga ovamile noma i-panizo yenkangala.
Umcwaningi UDolores Curt weqembu le-GA-UPM Ukugcina lokho " usawoti osemhlabathini noma ekuniseleni kunomkhawulo wezitshalo eziningi zezolimo, kepha kungaba yithuba lokukhiqiza i-biomass engancintisani nomkhakha wezokudla kwezolimo futhi ngaleyo ndlela ithuthukise ukusimama kwayo. Umoba ovamile isivuno samandla esivumelana nosawoti futhi sisekelwa yi-European Union. Ngazo zonke lezi zizathu, kubalulekile ukwazi ukuthi kungakhuthazwa kuphi nokuthi umkhiqizo wayo uzomelani ”.
Njengoba lo mcwaningi esho, usawoti uyisici esibaluleke kakhulu (Kunezici eziningana zalolu hlobo) okufanele uzinakekele lapho wenza umhlaba ulungele izilimo zokudla kwezolimo kusukela usawoti uthinta ukukhula kwezitshalo ngokuqondile nangokungaqondileKungenxa yomonakalo odalwe usawoti noma ngenxa yokwehla kokumunzwa kwamanzi yizimpande, okuthile okubalulekile ekusindeni kwezitshalo.
Ngalesi sizathu esifanayo futhi ukuze izitshalo zokudla kwezolimo (ezinomkhiqizo ophansi) noma zomhlaba ongasetshenziswanga zingapheli, bakhetha ukusebenzisa la mazwe asemaceleni, izindawo ezinosawoti, ukulima izinhlobo ezithile zezitshalo eziphikisayo noma kunalokho, ziyabekezelelana kuya kasawoti.
Isibonelo esicacile nokuvusa isasasa labacwaningi abaningi kule ndawo ku umhlanga ovamile Njengoba ingenakho nje lokho kubekezelelana nosawoti kuphela, kodwa futhi isitshalo esihlala isikhathi eside se-herbaceous (isitshalo esingeyona okomzimba esikwaziyo ukuphila isikhathi esingaphezu kweminyaka emibili), sijwayela izimo ze-edaphoclimatic, okungukuthi, izimo eziphathelene nenhlabathi nesimo sezulu.
Iphinde isinike i- ukukhiqiza okuphezulu ngokuya ngokuvunwa kwaminyaka yonke kwe-lignocellulosic biomass kusho ukuthi.
Ngale njongo, abacwaningi be-GA-UPM basungule indlela ethile yokulinganisa ukukhiqizwa kwe-biomass okungabandakanya ukusetshenziswa kwezindawo ezinosawoti omuncu kanye nezindawo ezinganakiwe ezinethuba lokunisela ngamanzi anosawoti, ukuze ukukhiqizwa kwe-biomass nomhlanga ovamile.
Le ndlela esetshenzisiwe inemisebenzi yezobuciko yokuphendula ukutholakala kwamanzi kanye ne- isivuno sikamoba ovamile usawoti, ngaphezu kokuthola imininingwane eqondiswe nge-geo. Ukucabangela amazinga ahlukahlukene ahlukahlukene kasawoti angatholakala endaweni futhi ngokusobala emanzini okunisela. Futhi ukulandela izindlela zokusimama ezingatholakala.
UJavier Sanchez, umbhali oyinhloko womsebenzi, uyasitshela; "Le ndlela isetshenzisiwe odabeni lweSpain esenhlonhlweni kepha ingasetshenziswa nakwezinye izindawo zaseMedithera ezinemininingwane etholakalayo yendawo", lapho sithola imininingwane emangalisa ngempela, futhi ngokwezibalo ezitholakele siyabona ukuthi eSpain kukhona duze kwe Amahektha angama-34.500 omhlaba wezolimo ubekelwa eceleni ngosawoti lapho ukutshalwa komoba ovamile kungaba inketho enhle kakhulu ekusetshenzisweni kahle kwale mihlaba kanye nokusimama.
Ngakho-ke, kungenzeka ukuthi kube nokukhiqizwa kwe-biomass okungaba khona kwamathani ayi-597.400 wezinto ezomile ngonyaka, ngokusebenza kukagesi okungama-25%, okuguquguqukayo, uma umuntu ngamunye edla u-730 KWh ngonyaka, okungahambelana amandla ngonyaka cishe angama-10.5 million gigajoules (GJ)
Ngenxa yalo msebenzi nomzamo weqembu le-GA-UPM, iSpain ingaba yiphayona ekukhiqizeni i-biomass esimeme ngokusebenzisa amasimu kasawoti asezingeni elincane esikhundleni sokuba namahektha angama-35.000 omhlabathi ongakulungele ukulinywa kokudla kwezolimo.
