Lipid rich biomass is the source of foods oils. With population growth, the amounts of waste volume will increase. It is important to improve the processes of valorization of these residues, through their conversion into alcoholic esters of fatty acids, which can be used as fuel or in other domestic and industrial applications. This volume reviews advances and innovative applications in this field. It will encourage the use of new works and even unpublished works to use biomass or its components for the production of bioproducts and biofuels.
