Down District Farmers for Renewable Energy (DDFFRE) invited David Surplus, MD of B9 Energy’s anaerobic digestion company to visit them at their monthly recent meeting in Downpatrick Cricket Club last Thursday night.
At a meeting chaired by local Councillor Cadogan Enright, They discussed the potential for co-operation around the development of renewable energy projects an in anaerobic digestion in particular . Cllr Enright explained “anaerobic digestion is a processes where micro-organisms digest biodegradable material in in a sealed container to release energy. Much of the fermentation used industrially to produce food and drink products use forms of anaerobic digestion. Silage is produced by anaerobic digestion”.
David Surplus pointed out “B9 is already involved in landfill gas at Down Councils’ Drumnakelly site, and based on the new anaerobic digestion plant being constructed in Dungannon, we are interested in farm scale projects utilising resources such as cattle and pig slurry together with excess silage to generate combined heat and power”.
David Surplus said; “South Down has not been as quick as other areas of the province to embrace AD in dealing with agricultural waste streams while deriving income from selling heat and power. Animal slurries could support up to 150 farm scale AD plants in the Province making a significant contribution to our renewable energy targets and reducing our over-reliance on imported fossil fuels”.
Micheal Trainor of Bishopscourt said “Recent demonstration has shown that when digestive left over from the AD process is spread on farm land there is a 35% increase in grass yields above the use of raw slurries due to the entrained nitrogen being in a form that is more easily absorbed. Weed seeds are also digested so that there is less need to use expensive imported herbicides which is important to me as an organic farmer.”
After dealing with normal business, the meeting supported a resolution from Alan Montgomery of Killough to follow up on this high tech way of dealing with farm waste to create new income sources for farming, reduce the danger of pollution from run-off, save money on herbicides and produce better grass and other crops. DDFFRE resolved to explore this technology more thoroughly at future meetings in the new year.
