Dairy farmers can save money while they save the planet
Dairy farming has long been accused of being a major environmental problem
because of the methane emitted by cows either through belching or to a lesser
extent flatulence, but that same gas can be captured and used to slash your
In fact, overall it is estimated that fourteen per cent of the world's
greenhouse gases are caused by agriculture and methane is rated as being 23
times more harmful than CO2.
But a Brisbane innovator could have come up with the solution for the smaller
dairy farm with an environmentally friendly, modular, small scale system of
turning farm waste such as cow manure into free energy that can be used for
heating, electricity or as an engine fuel.
Ron Lakin has developed the BioBowser, a small scale, affordable and practical
bio digester that produces methane gas and after the gas is extracted the
leftover material can be used as a nutrient-rich fertilizer.
The principal of converting waste to methane has been known for centuries. On
his epic journey in the 13th century Marco Polo commented that the Chinese were
tapping gas from the sewers and using it for cooking. Large intensive dairy
farms in Australia as well as piggeries, feed lots and abattoirs have long been
harvesting methane to use as an energy source. But these require large one-off
systems that can cost millions to build even though they pay back the capital
outlay in energy savings in a few short years.
"All we need to know is the quantity of waste available on a regular basis and
the energy requirements, and we can tailor the BioBowser system to suit the
individual needs. If the amount of waste increases or more gas is needed we can
put in more units as the system is modular," Ron says.
"A dairy farm milking 3 to 400 cows is likely to have 5 tonne of manure waste a
day which and can produce 80 M3 of biogas, the equivalent of 60kg heat value of
"This amount of gas is likely to be sufficient to meet the usual energy needs,
such as milk chilling, water heating and even heating the dairy on those cold
"Each BioBowser has to be tailored to suit the circumstances, such as the
production of electricity or the use of gas as fuel for farm machinery as well
as being plumbed into the farm site," Ron Lakin said.
About BioBowser Technologies: BioBowser is a small Australian start-up company
that provides an environmentally-conscious waste solution that reduces
greenhouse gas emissions and the cost of waste treatment, while producing clean
burning biogas for heating, cooking or converting into green electricity.
