A low-energy process for the conversion of fisheries waste biomass

Studies have been conducted in the composting of fisheries processing wastes with peat as a means of recovering the valuable biomass present in the fish waste. Subsequently, extracts from this compost were utilized as a substrate source in the growth of microorganisms in submerged fermentation. The production of fish wastes - peat compost was found to be an easy and inexpensive process which required a low energy input. The concentrations of nutrients such as N were higher in the compost than in the original peat. Thus, a process of bioconversion from a waste material to a product with commercial potential can be conducted with minimal energy requirements.
