La United Airlines sarà la prima compagnia aerea negli Stati Uniti a utilizzare combustibili alternativi su voli passeggeri. Martedì ha infatti annunciato un investimento da 30 milioni di dollari in una delle maggiori società di settore, la Fulcrum BioEnergy.
Fulcrum usa spazzatura e oli derivati da grassi animali per realizzare un biocarburante sostenibile che può essere mescolato con il carburante derivato dal petrolio.

La quantità di biocarburante che la compagnia americana intende acquistare è minima rispetto al gigantesco volume dei suoi consumi è tuttavia un inizio, anche perché l'industria del volo è stata messa sotto intensa pressione da parte dell'amministrazione Obama per ridurre le emissioni inquinanti.
Per le prime due settimane quattro o cinque voli al giorno saranno alimentati da un mix di 30 per cento di biocarburante e il resto carburante tradizionale, dopodiché il carburante "spazzatura" verrà usato sul resto della flotta.
