A renewable resource, also known as a flow resource, is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of ti ...
, non-petroleum, liquid fuels that can substitute for
gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic co ...

In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and hydrophobic, and their odors are usually weak or ex ...
constitute the P-series fuel. These fuels are clear,
high-octane alternative fuels that can be used in flexible fuel vehicles. It addresses 3 problems: the need for non-petroleum energy sources, solid waste management, and affordability. The feedstock is not incinerated, but chemically digested, so there is no combustion with the accompanying toxic air emissions.
