Ngemuva kwethemu i-methanization ifihla inqubo engokwemvelo yokwehla kokonakala kwezinto eziphilayo lapho kungekho umoya-mpilo. Lokhu kukhiqiza igesi ngakho-ke amandla. Izinkampani eziningi namuhla zisebenzisa le ndlela ukuqeda imfucuza yazo, zisebenzisa imithombo emisha, engaziwa yamandla athakazelisayo.
Amakhabe abolile
Isikhathi ngasinye, inkampani yezithelo eFrance ithola amathani ayi-2000 amakhabe ukuthi abakwazi ukuthengisa. Kodwa-ke, ukuphathwa kwalolu doti kunenani elilinganiselwa ku- € 150.000 ngonyaka ukuthuthwa nokwelashwa. Ngo-2011, inkampani yathola iyunithi ye-methanization eyenziwe yinkampani yaseBelgium, I-GreenWatt. Isimiso silula. Izithelo ezilimele noma ezibolile zibekwa endaweni lapho zilinyazwa khona ngama-bacterium akhipha ama-biogas. Amandla akhiqizwayo athengiswa kabusha, kanti ukushisa kusetshenziswa ngaphakathi kwemboni uqobo.
Izaqathe ezibolile
Isimiso esifanayo senzeka ngoqathe. Iqembu laseFrance, omunye wabaholi baseYurophu ekulimeni isanqante, eyasungulwa ngonyaka we-2014 iyunithi ye-biomethanization, nayo eyenziwe yinkampani I-GreenWatt. Leli qembu likhiqiza amandla alingana namakhaya angama-420.
Amandla avela kushizi
Ushizi unezindawo ezingalindelekile. Inyunyana yabakhiqizi endaweni yaseSavoy, eFrance, ivule nyakenye u-Okthoba uphiko lokuguqula u i-lactoserum, uketshezi oluphuzi olukhiqizwa ngokwenziwa koshizi. Ngaphezu kokukhiqizwa kwebhotela, le nto futhi ingumthombo wamandla ngenqubo ye- meti-anization. Lolu phiko kufanele luvumele ukukhiqizwa kwamandla acishe abe yizigidi ezintathu kWh wamandla ngonyaka, okungukuthi, okulingana nokusetshenziswa kukagesi kwezakhamizi eziyi-1500.
Indle yabantu
Ibhasi elithile kakhulu lihamba emigwaqweni Bristol, ENgilandi. Ukuqala kwemoto ukuthi ijikeleza ngenxa yendle yabantu. Unguphethiloli oluhlaza ngoba ukhipha u-80% wekhabhoni futhi uphakathi kuka-20 no-30% ka i-dioxide i-carbon ngaphansi kwenjini kadizili. Le biobus ingahamba ibanga elingamakhilomitha angama-300 ngenxa yendle yemvelo yaminyaka yonke yabantu aba-5. Ibhekene nempumelelo yephrojekthi yayo yokuhlola, inkampani I-GENeco usanda kwethula isicelo soxhaso kuHulumeni ukuze athuthukise inethiwekhi yakhe yamandla ahlanzekile.
Kunezinzuzo eziningi ze-biogas. Ingasetshenziswa njengokunikezwa kwamandla emahoreni angekho phezulu, ngoba ayidingi ilanga noma umoya ukuyikhiqiza futhi ayidingi amabhethri ukuyinqwabelanisa.
