Preliminary LCA of three Peruvian fishmeal plants

Fishmeal and fish oil are largely used as input to several animal feed industries, but there is a lack of LCAs on Peruvian fishmeal plants, despite their predominance in the global supply. Preliminary LCAs where performed on three different types of Peruvian fishmeal plants with the objective of comparing them and suggesting ways of limiting their impacts. Two system boundaries were used: one including the fishery and another excluding it in order to enable others to use our dataset. We used the SimaPro software, the ecoinvent 2.2 database and the ReCiPe method. Despite the predominant impact of the use phase, in particular consumption of fossil energy, the construction and maintenance phases contribute significantly when fishing is excluded from the system boundaries. Furthermore, existing screening LCAs of the use phase underestimate significantly its environmental impacts. The environmental benefit of using natural gas instead of heavy fuel as energy source is quantified. The comparison of environmental impacts between different qualities of fishmeal shows higher impacts of residual fish meal, intermediate impact of standard fishmeal and lower impacts prime fishmeal. Future studies on other fishmeal and residual fishmeal plants should take into account the construction and maintenance phases, and more items in the use phase than in historical screenings. There is room to decrease the environmental impact of this industry in Peru.
