From Poo to Power

Zero impact dairy farming

Zeecol farm technology recycles cow manure, transforming nitrate-rich effluent into fuel, fertiliser, electricity, and high protein feed for use on farm. The Zeecol system significantly reduces both farm input costs and environmental impact.



Turn your waste streams from a cost centre into a profit centre

A sustainable and competitive new model

With current NZ dairy pay outs below production costs of approx. $5/milk solid, dairy farmers are searching for answers to compete globally. The revolutionary Zeecol farm system utilises already proven biodigester and bioreactor technology. Farm input costs are reduced by recovering usable energy.
The system requires hardware to be installed on the farm. The equipment is owned, managed and maintained by Zeecol. The farmer is charged for the facility’s output at a rate of 80% of the comparative input costs that are being replaced.


Lessons from the US Clean Water Act for NZ Dairy Farmers

In 2011, the Parliament with the backing of the majority of people in New Zealand, created the Environmental Protection Authority. New Zealand’s own EPA. Like other environmental agencies around the world, New Zealand’s EPA had sweeping new powers to protect the environment of New Zealand. At that time Zeecol founder, William Mook could see the writing on the wall for New Zealand’s dairy industry.

Take the 1976 clean water act. When New Zealand’s EPA placed 800 sampling stations across the country, it was clear that the dairy industry would be looked upon as a major culprit, just as it was in the USA. In the early 1970s the USA had 12.5 million dairy cows. After 5 years, the number of dairy cows plummeted to 6.0 million. The value of farms plummeted too.

Technology developed by NASA to feed cows on the moon

creates a feed source costing 80% of traditional feed

Between 1958 to 1978, NASA researched developing permanent bases on the moon, including raising cows using algae. Much of this technology has been commercialised and applied since to nutritional and feed production. Today, 30% of the world’s commercial algal production is already sold for animal feed. The powerful nutritional benefits are well documented. Algae allows feed production with a daily harvest all year round, bringing security of supply.

Manure Process

Waste is captured from feedlots or barns and goes to a sealed manure process in an anaerobic digester producing a variety of gases, liquids and solids.

Enzyme Process

Water and biomass are sent to the enzyme process which extracts oils to produce high quality feeds, enriched fertilisers, petrol and diesel.

Gas Process

The gases are split.  The methane is burned to produce electricity for the farm.  Heat produced is used to chill product and heat water.  Surplus methane is used to power farm vehicles.


The algae-based feed maximises milk production by delivering a balanced TMR (Total mixed ration).

Algae Process

CO2 from both the manure process and the gas process is extracted and sent to the Algae unit, along with water from the manure process.


The fertiliser outputs are included in fertiliser spread on the farm, providing nutrients in a bio-available form.


Poop to Power

A visit with a mid-Canterbury farmer, Wyvern Jones, who has committed to the Zeecol system. Wyvern explains how the Zeecol system creates a zero waste farming environment, enabling farmers like him to meet waste management compliance, reduce environmental impact and improve profitability.

Cow muck ‘worth more than milk’

To combat sustained period of low world milk prices, Yorkshire dairy farmer, David Metcalfe has converted to a system that allows him to generate electricity from waste. Metcalfe said his family farm was now earning about £50,000 a year, and saving up to another £100,000, by converting slurry into electricity. In contrast, Metcalfe Farms was facing a “considerable” loss of money on the milk produced from its 900 strong herd of dairy cows. Low dairy prices meant the farm … see more: The Global Dairy.
