El ipere Sisityalo esityebileyo kwiswekile nenqanaba eliphezulu lotywala, ngoko ke sineempawu zendalo ezibaluleke kakhulu ekufuneka zisetyenziselwe ukuvelisa i-biogas okanye amandla ombane.
Isivuno saso siphezulu siqinisekisiwe kuthathelwa ingqalelo ukuba ihektare enye ye-nopal inokuvelisa ii-cubic metres ezingama-1 biogas okanye iilitha ezingama-25.000 zedizili, ngaphezulu kwezinye iintlobo ze Ingca.
Umthamo wekhalori we-nopal uyafana nowerhasi yendalo kodwa ucocekile.
Esi sityalo asidingi matshini mkhulu okanye iinkqubo zokulima ngenxa yoko siyindlela efanelekileyo yokuvelisa i-biofuels okanye amandla.
Inkqubo yokuguqula i-nopal ibe yi-biofuels inenzuzo yezoqoqosho, yiyo loo nto kulindeleke ukuba i-boom enkulu isebenzise esi sityalo njengomthombo wamandla.
UMexico ngomnye wabavelisi abaphambili be-nopal kuba kukutya kwemveli okutyiwa ngokubanzi ngabemi bayo. Ujongene nale meko intsha, eli lizwe linethuba lokwandisa imveliso kunye nokuvelisa inzuzo ebonakalayo.
I-nopal yongezwa kuluhlu olude lwezityalo apho amandla anokuveliswa khona okanye mafutha. Kubalulekile ukuba izityalo ezahlukileyo zisetyenziselwe ukunqanda ukulima monoculture kusetyenziso lwamandla njengoko onakalisayo okusingqongileyo kwaye ethoba iimeko zendalo ukuze umhlaba ungabinakuqhubeka nokusetyenziswa.
Ukusetyenziswa kweendlela ezizinzileyo zezolimo kunye neenkqubo zibalulekile ukuze sikwazi ukuvelisa izibaso ezisekwe kwisityalo kwixesha elide.
I-Prickly pear yinto elungileyo kakhulu eluhlaza kwizityalo ze-biogas kuba zitshiphu kwaye zinesivuno esihle kakhulu, kodwa imveliso ebalulekileyo iyafuneka ukubonelela.
Ukuvavanya ubungakanani kunye neemeko zemveliso eziyimfuneko kwisityalo ngasinye kubalulekile xa ukhetha uhlobo lwesityalo oza kusetyenziselwa ukuvelisa umbane.
Njengomphengululi ozinikele kufundo lwe-nopal njengesityalo esinamandla, ndiyabubulela ngokungazenzisiyo ubukho beli nqaku, kodwa ndicinga ukuba kungacetyiswa ukuba uthathe unonophelo ngakumbi ekubhaleni kwalo (ukuze ingazisi ukungaqondani) kwaye uphonononge amanani emveliso yokuvelisa i-biogas, ebaxiwe Ngokoluvo lwam, nakwimeko elungileyo.
