“…Approximately, 71% of the earth's surface has been covered by water, which is being polluted by human beings by different industrial activities and pouring wastes into rivers and coasts. 63 The conversion of wastewaters into biomass and biodiesel by cyanobacteria is an appropriate method for energy harvesting from organic compounds. The waste material and by-products are concerned as cheap organic sources for biofuel production.…”

Cyanobacteria are photosynthetic microorganisms which can be found in various environmental habitats. These photosynthetic bacteria are considered as promising feedstock for the production of the third‐ and the fourth‐generation biofuels. The main subject of this review is highlighting the significant aspects of the biofuel production from cyanobacteria. The most recent investigations about the extraction or separation of the bio‐oil from cyanobacteria are also adduced in the present review. Moreover, the genetic engineering of cyanobacteria for improving biofuel production and the impact of bioinformatics studies on the designing better‐engineered strains are mentioned. The large‐scale biofuel production is challenging, so the economic considerations to provide inexpensive biofuels are also cited. It seems that the future of biofuels is strongly dependent to the following items; understanding the metabolic pathways of the cyanobacterial species, progression in the construction of the engineered cyanobacteria, and inexpensive large‐scale cultivation of them.

“…However, the high amount of unsaturated lipids made biodiesel produced from microalgae biomass less stable. Other drawbacks of microalgae as a biodiesel feedstock are the need for a high amount of nutrients (nitrogen and phosphorus) (51) and the ability of certain species to produce harmful toxins (52). Despite this, many researchers consider microalgae as the only renewable energy source that could completely replace fossil fuels (53).…”

“…The LCA research works reported that the land required for agricultural systems was 96% higher than for the algal biodiesel production (245). Moreover, microalgae cultivation can be associated with carbon capture from flue gas emissions and wastewater treatment (52,246). It was reported that 1 kg of algal biodiesel fixes about 0.6 kg of CO 2 (247).…”

Although fossil fuels remain the main source of energy, the volume of renewable sources of energy is constantly increasing. Biodiesel is a promising alternative fuel due to the number of advantages compared to fossil fuel and other types of biofuel. The specific objective of this study was to identify the difference between conventional and novel technologies applied during the whole life cycle of biodiesel production and consumption. The study offers some important insights into the recent advances in the biodiesel industry including biodiesel production from microalgal lipids, advanced homogenous and enzymatic transesterification, non-catalytic supercritical transesterification, application of microwave and ultrasound assisting technologies. Considering all the factors affecting the efficiency and safety of the biodiesel production process, here we reviewed the main principals and recent achievements in the environmental life cycle assessment of biodiesel production and consumption.
