Production of biofertilizer from anaerobic fermentation of fish waste.
Fertilizer, growth promotion, residues.
The production of biofertilizers from the anaerobic fermentation of fish waste constitutes a sustainable alternative for utilizing byproducts from the fishing industry. During the process, microbial decomposition in an oxygen-free environment promotes the release of nutrients such as nitrogen, phosphorus, and potassium, as well as organic compounds that are easily assimilated by plants. This biotransformation reduces the pollutant load of the waste and generates an input with the potential to partially replace chemical fertilizers. The resulting biofertilizer has biostimulant properties, contributing to plant growth and improving soil fertility. Therefore, the use of this technology represents a circular economy strategy and the valorization of agroindustrial waste.
