Ezinyangeni ezedlule, indawo yokulawula ye-biodiesel iye yaba nezinguquko ezibalulekile ezifundeni eziningana ezibalulekile zezwekazi laseMelika. Izimemezelo zokwenyuka okuphoqelekile kwezingxube ze-biodiesel kumafutha, kokubili e-United States naseBrazil naseParaguay, zibe nomthelela ezimakethe zezolimo, izimboni, kanye nenqubomgomo yamandla, ngokulindelekile. izinguquko ezibalulekile ekusetshenzisweni nasekukhiqizweni kwama-biofuels.
Lezi zinqumo zezepolitiki ziphendula i isidingo sokunciphisa i-carbon footprint, ukuqinisa ukuvikeleka kwamandla kanye nokunikeza ezinye izindlela ezisimeme Lapho bebhekene nokuntengantenga kwezimakethe zomhlaba jikelele ze-hydrocarbon, ohulumeni bafuna ukuqinisa uchungechunge lwenani lezolimo kanye nokukhuthaza ukutshalwa kwezimali kwezobuchwepheshe nengqalasizinda.
I-United States kanye nokweqa ekuhlanganisweni kwe-biodiesel
La I-U.S. Environmental Protection Agency (EPA) wamangaza imakethe ngokuphakamisa a ukwanda okukhulu kwenhlanganisela eyisibopho ye-biodiesel kanye ne-diesel evuselelekayo iminyaka ka-2026 kanye no-2027. Uma kuvunyiwe, umthamo we-biodiesel ehlanganiswe nezibaseli ezimbiwa phansi uzokwenyuka ukusuka 3.350 billion amalitha (kuhlelelwe u-2025) ukuze 5.610 million ngo-2026 y 5.860 million ngo-2027Lokhu kwenyuka okungama-67% kuzoba ukweqa okukhulu kakhulu emlandweni wokuxubana okuyimpoqo ezweni laseNyakatho Melika.
Isimemezelo sesivele saqashelwa ezimakethe zezolimo., enokuntengantenga okukhethekile kwekusasa likabhontshisi wesoya okudayiswa ku-Chicago Board of Trade, uma kubhekwa ukuthi uwoyela wesoya uwukufaka okuyinhloko kokukhiqizwa kwe-biodiesel esifundeni. Amafemu akhethekile njenge-Hedgepoint Global Markets agcizelela ukuthi lesi sinyathelo sisesesigabeni sokubuyekezwa komphakathi nezingxoxo, kanti i-EPA iyakwamukela ukuphawula kuze kube umhla ziyisi-8 ku-Agasti.
Umphumela womthethonqubo omusha udlulela ngalé kokusanhlamvuUkwenyuka kwesidingo kungase kube nomthelela entengo kabhontshisi wesoya, okuphuma kuwo, nalo lonke uchungechunge lwawo lwenani, okuhlanganisa ukudla nokudla. Kulinganiselwa futhi ukuthi imboni yokugaya ubhontshisi wesoya wase-US ingakhulisa amandla ayo, ngamaphrojekthi aqhubekayo azokwengeza okungenani amathani ayizigidi ezi-5,1 ngonyaka emkhiqizweni wezimboni, afinyelele cishe amathani ayizigidi ezingama-74,5 ngo-2026.
I-Brazil isheshisa imodeli yayo yokuguqula amandla
Ngokuhambisanayo, I-Brazil inqume ukwenyusa ngokusemthethweni amaphesenti ama-biofuels emafutheni endabuko. Kusukela ngo-August, uphethiloli uzothwala a 30% ethanol -uma kuqhathaniswa nama-27% ngaphambilini— kanti udizili uzohlanganisa a I-biodiesel engu-15%., yeqa ukunqanyulwa kwangaphambilini okungu-14%. Lesi sinqumo sethulwe nguMongameli Lula da Silva njengengxenye Isu lesimo sezulu saseBrazil le-COP30 ezayo, ozoba kuleli.
Uhulumeni waseBrazil uthi lolu hlelo kunciphisa ukuthembela ekuthengisweni kukaphethiloli wezinsalela, ithuthukisa ukuvikeleka kwamandla kazwelonke, futhi isiza ukuqukatha izintengo zomthengi wokugcina. Ngaphezu kwalokho, iBrazil iqinisa isikhundla sayo njengomunye wabakhiqizi abahamba phambili emhlabeni be-ethanol ne-biodiesel, ikhuphula intuthuko yezolimo ngaphandle kwesidingo sokwandisa indawo yayo elinywayo.
Izikhulu zezamandla ziqinisekisa ukuthi lezi zingxube zizoba ne- umphumela ngokushesha ekunciphiseni amagesi abamba ukushisa kanye nasekuthuthukiseni ibhalansi yemakethe yamandla yaseBrazil. Izibikezelo zikhomba ukuthi imithethonqubo emisha izobaluleka kakhulu ekuguquleleni imodeli yamandla esimeme futhi enokuncintisana.
IParaguay ilungiselela ukukhulisa inhlanganisela ye-biodiesel
Inqubekelaphambili eNingizimu Melika iphothuliwe ngecala lika Paraguay, lapho umkhakha we-biodiesel nawo uphusha ukukhulisa iphesenti lokuhlanganisa eliyisibopho. Ngemva kokufika I-biodiesel engu-5%. ku-diesel, i Izinkampani ezikulo mkhakha zithi sezikulungele ukufinyelela ku-10%., ngenxa yomthamo ofakiwe—ongaba amalitha ayizigidi ezingu-200 ngonyaka—kanye nokutshalwa kwezimali okwenziwe eminyakeni yamuva.
Iziphathimandla nabakhulumeli bomkhakha bayakugcizelela lokho Kulelo nalinye ilitha le-biodiesel elingena esikhundleni sikadizili wendabuko, ukukhishwa kwe-COâ‚‚ kwehliswa kuze kufike ku-80%., okwakha intuthuko ebalulekile kwezemvelo. Ngaphezu kwalokho, baphikisa ngokuthi ukuqinisa imboni ye-biodiesel kukhiqiza umsebenzi, inani elingeziwe, namathuba ezimboni ezihlobene, ezifana nensimbi kanye nokukhiqizwa kukawoyela wesoya.
Nakuba izingxoxo nohulumeni ziqhubeka kancane, lo mkhakha unethemba lokuthi kungenzeka maduze kufinyelelwe ukuhlanganiswa okukhulu kwama-biofuels emxubeni wamandla, okuzovumela iParaguay ukuthi yehlise ubungozi bayo bokuntengantenga kwamazwe ngamazwe emananini kaphethiloli.
Umthelela wezolimo nezinselelo zezimboni
Ukuhlangana kwalezi zinyathelo ezimakethe ezifanele njenge-United States, Brazil kanye neParaguay kukhombisa ukuthi Ukwanda kokusetshenziswa kwe-biodiesel kulungisa ezolimo zesifunda nezamazwe ngamazwe.Uwoyela kabhontshisi wesoya nezinye izinsiza zezolimo zihlangabezana nesidingo esikhulayo, esingase sibe nomthelela emananini nasekuhlinzekeni, kube nemiphumela kulo lonke uchungechunge lokudla namandla.
Ngesikhathi esifanayo, imboni kufanele isheshise ukunwetshwa kwayo amandla okucubungula, ukugcinwa kanye nokusabalalisa ukumunca imiqulu emisha edingekayo, emele inselelo yokuhlela kanye nethuba lokutshalwa kwezimali kanye nokuthuthukiswa kwezimboni.
El cindezela i-biodiesel Iyaqina njengesixazululo esinezici eziningi esisivumela ukuthi siye emnothweni wekhabhoni ephansi, sinciphise ukuncika emafutheni ezinto ezimbiwa phansi, futhi sivule amathuba amasha embonini yezolimo neyezimboni ezindaweni ezahlukene.
