Explora, a public-private initiative innovates to transform sewage waste into oil molecules that exported to Europe. They use it as raw material for second-generation biofuels. They developed the technology over eight years, with the idea of not relying solely on soy for biodiesel production. They have already invested $5 million in the sewage sludge de-aeration stage. Also, an initial investment of $30 million made for the biodiesel production plant in 2006. A module is building now for the recovery of fatty matter from the sewage sludge stream. The investment will be between $5 and $20 million.
