Processes
This study evaluated the environmental impacts of producing 1 kg of biomass for animal
feed grown in inland fisheries effluents as a culture medium using the ReCiPe method. Four scenarios
with two downstream alternatives were modeled using the life cycle assessment method: Algal
Life Feed (ALF), Algal Life Feed with Recycled nutrients (ALF+Rn), Pelletized Biomass (PB), and
Pelletized Biomass with Recycled nutrients (PB+Rn). The findings reveal a substantial reduction
in environmental impacts when wastewater is employed as a water source and nutrient reservoir.
However, the eutrophication and toxicity-related categories reported the highest normalized impacts. ALF+Rn emerges as the most promising scenario due to its reduced energy consumption,
highlighting the potential for further improvement through alternative energy sources in upstream
and downstream processes. Therefore, liquid waste from fish production is a unique opportunity to
implement strategies to reduce the emission of nutrients and pollutants by producing microalgae
rich in various high-value-added metabolites.
