Sewage-based Diesel

Slashdot:

A New Zealand company has successfully turned sewage into modern-day gold. New Zealand Herald is reporting that a Marlborough-based Aquaflow Bionomic yesterday announced it had produced its first sample of bio-diesel fuel from algae in sewage ponds. It is believed to be the world’s first commercial production of bio-diesel from ‘wild’ algae outside the laboratory – and the company expects to be producing at the rate of at least one million litres of the fuel each year from Blenheim by April.
