Aquaflow Bionomic Corporation
Aquaflow Bionomic Corporation (ABC) is a startup that has set itself the objective to be the first company in the world to economically produce biofuel from wild algae harvested from open-air environments, to market it, and meet the challenge of increasing demand.
The company’s office is in Nelson, New Zealand and laboratory and field development work is done in Malborough.
The world’s first wild algae bio-diesel (5% mixture with 95% normal diesel), produced in New Zealand by Aquaflow Bionomic Corporation, was successfully test driven in Wellington on December 15, 2006 by the Minister for Energy and Climate Change Issues, David Parker.

The directors of the company are Vicki Buck, Nicholas Gerritsen, Barrie Leay and David Milroy.
Technology
ABC harvests algae directly from the settling ponds of standard Effluent Management (EM) Systems and other nutrient-rich water. The process can be used in many industries that produce a waste stream, including the transport, dairy, meat and paper industries. It uses dissolved air flotation (DAF) plus floc then a belt press system to extract the algae at a 8 to 10% concentration. The two-step process firstly optimises the ponds' productive capacity, and secondly, determines the most efficient and economic way of harvesting the pond algae. Algae are provided with full opportunity to exploit the nutrients available in the settling ponds, thereby cleaning up the water. The algae are then harvested to remove the remaining contaminant. A last stage of bio-remediation, still in development, will ensure that the water discharge from the process exceeds acceptable quality standards.
The water and sludge treatment process is an elegant clean-up and management service to councils responsible for sewage treatment systems while also generating a low-cost feedstock for conversion to fuel.
Further processing involves adding chemicals and processing the algae - water sludge mixture at super critical water temperatures and pressures around 230 bar 400 C.
The result is an algae-based extract that will ultimately be converted to an alternative fuel source. The process is at present energy negative.
“In the Aquaflow process there is no conflict with land use or with the production of food crops as is occurring in America and Europe, which is becoming an increasing world problem.”
Leay explains that the essence of Aquaflow’s process is to use algae to capture ‘current sunlight’ through photosynthesis, which is the identical process used millions of years ago, when the world’s oil and gas deposits were laid down, using ‘ancient sunlight’.
“But as we all know those sources of captured ‘ancient sunlight’ are now being rapidly depleted as we reach Peak Oil.
“An extraordinarily beneficial by-product of the Aquaflow process is potentially releasing a clean water resource of millions of litres of clean water - to be recycled and available for use in irrigation, industrial washing, cooling, and so on.”
Marlborough site
The Marlborough sewage pond details are:
60ha of open oxidation ponds, serving a population of 27,000 with a mix of municipal and agro-industrial waste - including a significant wine industry - and with an annual water flow of 5 billion litres.
“We have now achieved commercial scale continuous harvesting of tonnes of wild algae at the Marlborough oxidation ponds so we can take the step up to commercial scale production of biocrude,” says Aquaflow chairman, Barrie Leay.
The present installed equipment can harvest 300 to 400 Kg of processable material per day of which 8-10% is algae.
Media
In December 2006, Aquaflow Bionomic Corporation demonstrated how its algae-based fuel additive works in the standard diesel engine of a production vehicle, outside Parliament buildings in Wellington. The fuel was a mixture of 95% diesel and 5% laboratory derived algae based oil. .
