| Abstract |
This research addresses the constraints to biodiesel from microalgae biomass, and discusses how to turn microalgae large-scale cultivation feasible considering the hypothesis that open pond systems are preferable for low added-value products such as biofuels. Flue gas can be used as a source of CO2 for microalgae cultivation, and several studies have been discussed the benefits and limitations to use algae to capture CO2 for GHG (greenhouse gases) mitigation. The cement sector is a large contributor to GHG emissions, mainly CO2. Carbon capture technologies must be adopted to make the cement industry more sustainable. An increasing number of studies have focused on biofixation of CO2 from cement flue gas by microalgae. Besides the environmental benefits, in a carbon pricing context, it may represent a business opportunity. A conceptual circular business model was developed based on industrial symbiosis principles, where a raceway plant for microalgae cultivation is co-located beside a cement plant as flue gas source in order to capture CO2 emissions and to produce biomass used as raw material for biodiesel production in Brazil. A multidimensional analysis (technical, economic and environmental) was carried out. The results highlighted the challenges of feasible large-scale microalgae cultivation in raceways due to an extensive land area required, and the important role of considering both sustainable dimensions in decision making, i.e. considering an environmental assessment added to the technical and economic analysis. |
