AI overview
Biodiesel is a fuel made from natural oils like soybean or canola oil through chemical processes that convert them into compounds suitable for engines. It matters because it can be used to power vehicles and trains, offering a renewable alternative to petroleum-based diesel fuel.

Biodiesel is a renewable biofuel, a form of diesel fuel, derived from biological sources like vegetable oils, animal fats, or recycled greases, and consisting of long-chain fatty acid esters. It is typically made from fats.
