Abstract(s)
The primary aim of this research was to evaluate and compare the environmental impacts,
throughout the life cycle, of the main treatment systems employed by the industry, as well as
to identify the processes that contribute most to these environmental impacts. To achieve this, a
bibliographical search was conducted using theWeb of Science Core Collection database platform,
utilizing the keywords “life cycle assessment”, “pig”, “treatment”, and “manure” or “slurry”. The
search was restricted to publications from the last five years (2019–2023), resulting in a total of
66 publications that were then analyzed according to the functional unit (FU) adopted. For the
10 publications whose FUs were expressed in tons or cubic meters of treated manure, a descriptive
and quantitative analysis was carried out. It was found that anaerobic digestion has been the
most widely used treatment technology for pig manure over the past five years, according to the
LCA methodology. These systems, configured as biogas and biofertilizer production facilities, have
proven to be environmentally friendly and could play a crucial role in the energy transition and
decarbonization of the energy matrix.
