- Life-cycle assessment of microalgae biodiesel: a reviewPublication . Figueiredo, Filipa; Garcia, Rita; Gonçalves, Margarida S.; Castanheira, Érica; Malça, João; Oliveira, Ana Cristina; Matos, Cristina T.; Freire, FaustoMicroalgae are an attractive way to produce biofuels due to the ability to accumulate lipids and very high photosynthetic yields. This article presents a review of life-cycle assessment studies of microalgae biodiesel production, including an analysis of modeling choices and assumptions. A high variation in GHG emissions (between -0.75 and 2.9 kg CO2eq MJ-1) was found and the main causes were investigated, namely modeling choices (e.g. the approach used to deal with multifunctionality), and a high parameter uncertainty in microalgae cultivation, harvesting and oil extraction processes.
