Abstract: A life cycle assessment (LCA) of the olive pomace valorisation by means of a pyrolysis system has been performed. The environmental impacts associated with three different stages were evaluated. The first stage is the olive production, the second stage is the olive oil extraction, where the by-product olive pomace is used as a raw material for the pyrolysis system. An LCA screening of the ecological versus the conventional route has been complementary evaluated. The pyrolysis system yields char, gases and tar, involving the following stages: biomass drying and grinding, pyrolysis, separation of gases and char, gas cooling by consecutively using an air heat exchanger followed of a water one, and the separation of gases and tar.
