Non-road diesel fuel
The rail, open pit mining, and thermoelectric power generation industries rely on a special type of non-road diesel fuel, or TRM (thermoelectric rail mining). The fuel that is used by a few thermoelectric plants is the same as that which fuels large machines that are used in some open pit mining operations, as well as locomotives and railway machines used to transport cargo and passengers.
Among the characteristics that differentiate it from road diesel fuel is a concentration of a maximum of 1800 milligrams of sulfur per kilogram of fuel, which corresponds to 0.18% of this element in diesel. This diesel fuel contains biodiesel at the rate set forth by the current legislation.
