Co-products from biodiesel production

Abstract

The increasing demand of biodiesel for blending with fossil-derived diesel leads to a great production of residues and co-products. Adding value to these byproducts is of great economical and environmental importance. The residues generated in the vegetable oil production are mainly used in animal feeding, manure production and thermal energy generation. On the other hand, the focus on glycerin, the main co-product of biodiesel production, is the chemical transformation into products that can be used in the production of plastics and as fuel additives.
