Collection description
The food industry by-products and waste represent an opportunity for a more sustainable cultivation of biomass and products of high added value. Food wastewaters represent not only a problem for the producers, but most of all an environmental problem. In order to enhance these by-products and wastewater, the aquatic protists (commonly known as microalgae) can play a primary role in converting waste to products with high added value. The aim of this research was to valorize the food by-products and wastes using aquatic protists producers of high added value molecules. In particular we studied the side-streams from dairy, brewery and sugar industry as new medium for aquatic protists cultivation in order to obtain omega-3 oil. A techno-economic analysis was then carried out to evaluate the economic effectiveness of using these food waste as a growth medium compared to bulk materials. This thesis successfully designed and applied food waste valorization for the cultivation of biomass rich in omega-3 fatty acids. In particular the reuse of food by-products and waste has been designed for an industrially relevant aquatic protist strain (A. mangrovei) proving its effectiveness in reducing production costs.
