Many farmers who raise oilseeds use a biodiesel blend in tractors and equipment as a matter of policy, to foster production of biodiesel and raise public awareness.

One study focused on the emissions of non-criteria carbonyl compounds from the burning of pure diesel and biodiesel blends in heavy-duty diesel engines.

This specification standard specifies various test methods to be used in the determination of certain properties for biodiesel blends.

They are currently trialing a variety of energy sources including biodiesel blends, natural gas, compressed natural gas, liquefied natural gas, diesel additives, electric and diesel-electric combinations.
