Cover Story: The amount of solid and liquid organic waste as well as wastewater is continuously increasing all over the world; therefore, the necessity to reuse and recycle them is becoming more and more pressing. Furthermore, the limited amount of fossil fuel resources and the need to reduce greenhouse gas emissions advocate for the production of renewable fuels. In this work, we analyze a sustainable second-generation process to produce biodiesel via the transesterification of waste cooking oil coupled with a third-generation process in cascade to recycle incoming wastewater rich in glycerol. This is used as a feed for microalgae, from which oil is extracted to further produce biodiesel and close the cycle. The experimental results at the pilot scale confirm the quality of biodiesel; the obtained yields for the two-stage process prove its competitiveness on the global market. View this paper
