Manta Biofuel is a producer of renewable algal crude oil that is cost-competitive with traditional crude oil. The company employs technological advantages in a three-step process to produce crude oil from algae. The first is growing algae. Manta can convert algae from any source, leaving options open from farming to collecting natural blooms. For the second step, harvesting the algae, Manta uses a proprietary magnetic harvester that efficiently collects and concentrates algae. The company then converts the algae to crude oil through hydrothermal liquefaction (HTL).
