Abstract:
The demand for wood for energy production in Ireland is predicted to double from 1.5 million m3 over bark (OB) in 2011 to 3 million m3 OB by 2020. There is a large potential for additional biomass recovery for energetic purposes from both thinning forest stands and by harvesting of tops and branches. This research builds on previous Irish studies which have focused on harvesting, by expanding the system boundary to seedling production and road construction through to biomass transportation. Results show that the production of 1 m3 of roundwood produces 12.86 to 14.73 kg CO2eq, while 1 m3 wood chip produces 0.58 to 1.70 kg CO2eq, depending on the scenario. The production of 1 m3 shredded bundle produces 5.76 to 6.16 kg CO2eq. This compares favourably with the production of willow chip for energy generation.
