چکیده
Olive oil production sector plays an Portuguese economy. It had a major growth ove increasing its weight in the overall national exp market penetration for Mediterranean traditio increasingly more demanding, especially in the N markets, where consumers are looking for more su Trying to support this growing demand this study production under the environmental and eco-effici The analysis considers two consecutive product olive trees farming; and olive oil extraction in mills farming, data collection covered two different middle-size farm (~12ha) (F1) and a large-size fa Results from both farms show that olive collec responsible for the largest amounts of Green Ho emissions. In this activities, estimate for the Car olive was higher in F2 (188g CO2e/kgolive) th CO2e/kgolive). Considering olive oil extraction, tw were considered: one using a two-phase system (2P three-phase system (3P). Results from the study o that there is a much higher use of water in 3P. Ener similar in both mills. When evaluating the GH conditions are evaluated: a biomass neutral condi carbon footprint higher in 3P (184g CO2e/Lolive o CO2e/Lolive oil); and a non-neutral biomass condi increase its carbon footprint to 273g CO2e/Lolive oil the carbon footprint of possible combination subsystems, results suggest that olive harvesting i for GHG. Keywords—Carbon footprint, environmental i subsystem, industrial subsystem, olive oil.
