Renewable technologies for farm businesses

Over 40 farmers attended a renewables event at the beginning of Decemeber, organised by the Farmer Network in conjunction with H&H Land and Property and Burnetts solicitors.


Anaerobic Digestion

The event, which was funded by the RDPE North West Livestock Programme, began with a visit to an anaerobic digester at Alistair Wannop’s farm at Linstock Castle near Carlisle.  The digester became operational in June 2012 and turns silage, farmyard manure and cow slurry into electricity.  The 500-kilowatt plant cost £2.8 million and was designed by a German renewable energy company.  

During the tour, farmers questioned Alistair about what feedstuffs were needed for the digester.  Although initially the digester was filled with slurry, the majority of the feedstuff used has been silage.  Alistair has found grass silage as good a feedstuff as maize silage which, given the very wet autumn, means he is likely to concentrate on growing grass silage in future. 



The second visit was to a biomass boiler at Warwick Hall, a small hotel on the outskirts of Warwick Bridge.  Biomass (wood) fuelled heating systems burn wood pellets, wood chips or logs to power central heating and hot water. 

Islam Pearson, managing director of Eco Logic Living showed the farmers the 190kW HDG wood chip boiler which is housed in one of the buildings at Warwick Hall.  The boiler heats not only the hotel but also a number of other properties on the site.  Islam talked through the installation process and the relative costs and benefits of different types of biomass boilers and concluded that, when compared to LPG or oil, a biomass boiler can offer a significant reduction on heating bills.

Farmers were then invited back to Borderway Mart for lunch and had the opportunity to talk individually with renewable energy companies who had stands in the Mart’s show hall. The afternoon session then included talks from three speakers:-
