 Microalgae have great potential to produce low-cost commodities such as biofuels and animal feedstocks using sunlight and carbon dioxide. Raceway-style 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-rich 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.
