Biodiesel is potentially more cost effective than mineral diesel. 

With fuel bills representing 35% of operator's costs, using Biodiesel will enable savings to be made.

Biodiesel substantially reduces exhaust emissions (unburned hydrocarbons, carbon monoxide and particulate matter). 

It contains naturally occurring oxygen, which enables the fuel to burn more completely and all but eliminates the black smoke normally associated with diesel engines.

Biodiesel has very good intrinsic lubrication properties.

Using Biodiesel as a 20% mix with normal diesel has no reported effect on fuel consumption.  Some operators have actually suggested improved fuel consumption.  There may be a slight increase in fuel consumption when using pure Biodiesel, however the effects are mitigated by the improved ignition and combustion qualities of Biodiesel.

Biodiesel has a higher flash point than mineral diesel.  It is also biodegradable and non toxic, which makes it a safer and more environmentally friendly fuel to handle, particularly in sensitive areas. 

Biodiesel is naturally sulphur free so produces no sulphur dioxide, considered to be one of the main precursors to acid rain.

Biodiesel is made from renewable resources, which means it reduces the contribution of carbon monoxide (one of the main greenhouse gases) to the atmosphere.
