Today and due to the environmental awareness, people have turned to other types of fuel alternatives to petroleum such as biomass, a renewable energy source which is usually plant matter or residues from the forest, or even municipal solid waste.
Another source of biomass can be pomace, the solid waste that is left from the olive kernel during the olive oil extraction process. When the pomace is processed by the refineries to get the second grade oil, a solid residue is also produced, the pomace-wood.
