Innovative Technology
Will Promote Environmentally Friendly Farming Practices
With assistance of $990,000 from the
Newfoundland and Labrador Green Fund, New World Dairy Inc. of St.
David's will install an anaerobic digester and the necessary equipment
to operate a methane gas capture and utilization system. These measures
will allow the dairy farm to create a waste management solution for
manure, produce enough heat and electricity to operate their facility,
and produce a product that can be used as bedding for cows.
"The installation of the digester and
methane gas capture system will reduce up to 11,090 tonnes of greenhouse
gases annually, representing a significant positive environmental
benefit," said the Honourable Charlene Johnson, Minister of Environment
and Conservation. "This project demonstrates how we can take a waste
product, convert it to an energy source and also have by-products that
can be fully utilized. This new system will lessen the environmental and
economic costs associated with trucking manure to distant fields, reduce
odour that accompanies trucking and spreading manure, and increase the
nutrient value of the fertilizer."
An anaerobic digester is an enclosed
container that excludes oxygen from the system. A number of naturally
occurring bacteria break the manure down into a variety of gases,
including methane and carbon dioxide. The gas that is released during
the breakdown process is captured and burned, and can then be used as an
energy source. This process of combusting methane produces a substantial
reduction in GHGs. Methane is 21 times more potent a GHG than carbon
dioxide, the product of the combustion. Additionally, the manure that is
processed during anaerobic digestion produces a solid which is ideal
bedding material for dairy cows and a nutrient laden liquid that can be
used as fertilizer.
"Undoubtedly, the technology that will be
implemented at New World Dairy Inc. will have many environmental
benefits and enhance the operation of the largest dairy farm in our
province," said the Honourable Joan Burke, MHA for St.
George's-Stephenville East. "I am most pleased that we are able to
complement the work of an important industry in the area and showcase
environmental stewardship at the same time."
Through the capture and combustion of the
methane gas that is generated during the digestion process, enough
electricity and heat can be produced to service the farming facility.
This will eliminate the need for 41,000 litres of furnace oil per year
and potentially reduce their electricity use.
"We are excited about this opportunity
for the farming industry in the province that has such wonderful
environmental impacts," said Brent Chaffey, President of New World Dairy
Inc. "In so many ways, we will be able to reduce our environmental
footprint through production of clean energy to run the farm, less
compaction of soil in our fields from our heavy trucks that haul manure,
as well as a bedding product that is beneficial for the animals. This
will be state-of-the art technology for the dairy industry in the
province."
New World Dairy Inc. is the largest dairy
farm in the province and milks approximately 1,200 cows and farms more
than 2,000 acres of forage crop to feed the herd. In 2000, the company
established a rotary milking parlour which allows 40 cows to be milked
at a time, and extracts and records detailed data on individual cow
production, condition and performance.
