And that's because shipping has very tight margins, and they want cheap fuel, so they use something called bunker fuel, which was described to me by someone in the tanker industry as the dregs of the refinery, or just one step up from asphalt.
Asta pentru că transportul maritim are profituri foarte mici şi toți vor carburant ieftin, aşa că folosesc ceva numit combustibil pentru cazane, care mi-a fost descris de cineva din industria petrolieră ca fiind reziduurile rafinăriei, cu un singur grad mai presus de asfalt.
