Biofuels are an essential part of the European Union strategy for heightened self-sustaining energy usage and reduction of greenhouse gas emissions. For this reason, an objective has been set for 10% of fuels consumed by the vehicles in Europe to be biofuels by 2020. Biodiesel is the main biofuel currently being produced in the EU.

The key to biodiesel development is its economic and environmental sustainability, and that is the primary focus of the Integral-B project . Funds for this project come from the LIFE+ program from the European Union.

The Integral-B project is focused on joint biodiesel and biogas production in the same processing unit from used vegetable oils and other by-products from food industry and catering activities, as well as the valorisation of glycerine, a by-product of biodiesel production.
