Description
Currently, there is a growing demand for cleaner and sustainable technologies due to
environmental issues. In this sense, there is a necessity to manage the assessment of production
processes and the rationalization of energy consumption. In this study, an Energy Life-Cycle Assessment
(ELCA) was carried out through energy efficiency indicators, directed to the characterization and
renewability of the peach production system life-cycle in the Portuguese region of Beira Interior.
The study intends to investigate the non-renewable energy inputs from fossil fuels, as well as the
emissions resulting from machinery. In addition, warehouse energy inputs are analyzed, mainly
cooling systems of refrigerated chambers where fruits are preserved. This analysis aims to find
opportunities for technological, environmental and best practices improvements. Test scenarios were
analyzed and revealing soil groundcover maintenance is the operation with the largest impact in
the energy consumption of the production process (3176 MJ·ha−1
). In the post-harvest processes,
the energy consumption largest impact is given by the warehouse’s operations (35,700 MJ·ha−1
),
followed by transportation (6180 MJ·ha−1
). Concerning the emissions resulting from the fuels
consumption, the largest impact is due to the plantation machinery and the transportation from
warehouse to retailers info:eu-repo/semantics/publishedVersion
