Environmental analysis of Spirulina cultivation and biogas production using experimental and simulation approach

Microalgae is constituted by different compounds, interesting for the production of a wide range of endproducts by using different technologies. Many potential possibilities have been developed under the context of a biorefinery. The aim of this work is to evaluate the environmental performance of b...

The aim of this work is to evaluate the environmental performance of biogas production from Spirulina (Arthrospira maxima) through LCA using experimental and simulation results.
