Sewage to diesel fuel. A New Zealand company has successfully turned sewage into modern-day gold.
Marlborough-based Aquaflow Bionomic yesterday announced it had produced its first sample of bio-diesel fuel from algae in sewage ponds.
Okay. At what cost? Looks like they've got algae to deal with certain portions of sewage, and then they're processing the algae. Good idea. We've got lots of sewage to treat.
