Microalgae for Biofuels and Animal Feeds
The potential of microalgae biomass production for low-cost commodities—biofuels and animal feeds—using sunlight and CO2 is reviewed. Microalgae are currently cultivated in relatively small-scale systems, mainly for high value human nutritional products. For commodities, production costs must be decreased by an order of magnitude, and high productivity algal strains must be developed that can b...
متن کاملBiofuels from microalgae.
Microalgae are a diverse group of prokaryotic and eukaryotic photosynthetic microorganisms that grow rapidly due to their simple structure. They can potentially be employed for the production of biofuels in an economically effective and environmentally sustainable manner. Microalgae have been investigated for the production of a number of different biofuels including biodiesel, bio-oil, bio-syn...
متن کاملThird generation biofuels from microalgae
Biofuel production from renewable sources is widely considered to be one of the most sustainable alternatives to petroleum sourced fuels and a viable means for environmental and economic sustainability. Microalgae are currently being promoted as an ideal third generation biofuel feedstock because of their rapid growth rate, CO2 fixation ability and high production capacity of lipids; they also ...
متن کاملDo biofuels from microalgae beat biofuels from terrestrial plants?
Energy in algal oil 37.90 Energy in biogas from residual biomass 50.00 Estimated as 22.85 MJ kg 1 of urea and 2.94 MJ kg 1 of diammonium phosphate. Using sedimentation followed by continuous vacuum belt filters. Approximate only in view of the developmental nature of algal oil recovery processes. Estimated as 80.4 MJ m 2 of facility area divided by a 20 year working life and the mass of oil pro...
متن کاملBiofuels done right: land efficient animal feeds enable large environmental and energy benefits.
There is an intense ongoing debate regarding the potential scale of biofuel production without creating adverse effects on food supply. We explore the possibility of three land-efficient technologies for producing food (actually animal feed), including leaf protein concentrates, pretreated forages, and double crops to increase the total amount of plant biomass available for biofuels. Using less...
