| A LCA of the use of forest biomass (pulpwood from pine plantation thinnings chipped at a logistic terminal in Lozoyuela, Madrid) to produce thermal energy has been performed. The whole cycle has been studied, from the logging operations to the final distribution and consumption of heat at one of the main final user?s facility (a campsite with heated swimming pools). The fabrication, transport and final disposal of capital goods used during the processes have been also considered. The ReCiPe 2008 LCA methodology has been applied, using the SimaPro software. The considered impact categories were climatic change, ozone depletion, terrestrial acidification, fresh water and marine eutrophication, human toxicity, photochemical oxidants, particulate matter, terrestrial, fresh water and marine ecotoxicity, ionizing radiation and natural land transformation. The chosen functional unit was the thermal MWh available to final users. The most relevant impacts come from the use of electricity ? taken from the Spanish net ? to feed the chips to the boiler and to distribute the heated water. Because of that, the alternative of using only photovoltaic electricity was studied, and the majority of the negative impacts were significantly reduced. Also the LCA of the present heat production with woodchips was compared to the alternative of using a similar performance diesel oil boiler. The latter would increase strongly the majority of the negative impacts. | |
