 Microalgae have great potential to produce low-cost commodities such as biofuels and animal feedstocks using sunlight and carbon dioxide. Raceway type open pond systems are best suited for this purpose due to their ability to produce large quantities of biomass at low cost. Cultivating high protein and long chain omega-3 fatty acid algae for animal feedstocks is also possible with these systems. Additionally, many different cultivation techniques, algal species, harvesting methods, and biomass processing technologies are being developed around the world.
