John Gilliland is the Managing Partner of Brook Hall Estate, L’derry, Northern Ireland. The Estate currently grows c.130 ha of short rotation willow and processes, dries and grades some 3,000 tonnes of dry woodchip each year.
In 1994, with help from AFBI (Agri Food & Bioscience Institute for NI) Loughgall, he planted his first willow on the farm. John has been closely involved with biomass production and utilization since that time and is now recognized throughout the world as one of the leading pioneers and innovators in this sector.
John is currently the Director of Original Heating. Original heating is the Regional Partner for the Austrian Biomass Boiler manufacturer for Ireland and Scotland. KWB is currently Germany’s best selling biomass boiler brand.
All heat for the farm, the farm houses, and driers now comes from a 300kW big bale boiler and 100kW KWB boiler, using the under and over sized woodchip, from the woodchip grading process. All electricity is wind electricity. Work continues with AFBI assistance to reduce the heat and electricity inputs.
