“…Microalgae recently attracted considerable attention as a next generation energy feedstock (Brennan and Owende, 2010;Fenton and Ó hUallacháin, 2012). Compared to other oil crops, microalgae have a number of compelling characteristics to support their development, including high per-acre productivity, short growth cycle, and utilization of non-arable land and a wide variety of water sources (fresh, saline, and wastewater) (Wu et al, 2012).…”

Microalgae biorefineries: The Brazilian scenario in perspective

2017

Biorefineries have the potential to meet a significant part of the growing demand for energy, fuels, chemicals and materials worldwide. Indeed, the bio-based industry is expected to play a major role in energy security and climate change mitigation during the 21th century. Despite this, there are challenges related to resource consumption, processing optimization and waste minimization that still need to be overcome. In this context, microalgae appear as a promising non-edible feedstock with advantages over traditional land crops, such as high productivity, continuous harvesting throughout the year and minimal problems regarding land use. Importantly, both cultivation and microalgae processing can take place at the same site, which increases the possibilities for process integration and a reduction in logistic costs at biorefinery facilities. This review describes the actual scenario for microalgae biorefineries integration to the biofuels and petrochemical industries in Brazil, while highlighting the major challenges and recent advances in microalgae large-scale production.

“…Nutrients in the form of commercial fertilisers are an expensive input for mass production of microalgae biomass (Collet et al 2010), particularly nitrogen and phosphorous (Fenton and Ohuallachain 2012;Lyovo et al 2010;Vaccari 2009). Large nutrient requirement can increase cost of microalgae biofuel production and compete with agricultural demand (Erkelens et al 2014;Fenton and Ohuallachain 2012).…”

“…Generally, microalgae biomass contains 30-40 % lipid, and up to 70 % of the residual biomass is left after the extraction process (Pragya et al 2013). Other challenges faced in largescale microalgae production is the need for fertilisers (Fenton and Ohuallachain 2012), high energy inputs required for harvesting and dewatering biomass , and challenges involved with lipid extraction and conversion processes (Pragya et al 2013). Anaerobic digestion can offer a pathway to eliminate some of the overheads of the production cycle by recovering nutrients from extracted residual biomass and the generation of electricity from methane biogas ).…”
