New processing scheme for algae biofuels


may have found a more efficient and cheaper to separate oil from algae. They use ultrasound and electromagnetic pulses to break down cell walls.

Then the algae solution is force-fed carbon dioxide, which lowers its pH, separating the biomass from the oil.

Not only is this much simpler than existing methods, it can be done in just minutes. Can it scale to commercial levels? Let’s hope so.
