Techno-Economic Assessment of APS-Based Poultry Feed Production with a Circular Biorefinery Process

Poultry livestock profitability significantly depends on feed, accounting for 60–70% of the total production cost, of which protein sources are among of the most expensive ingredients. The maintenance of profitability while meeting feed demand and reducing the environmental impact represents a considerable challenge driving research of alternative protein sources (APS), such as insects and algae meals. This study employs, for the first time, techno-economic assessment (TEA) methodology to evaluate the technological performance and the industrial feasibility of an APS-based poultry feed production method based on the valorization of the pre-treated organic fraction of municipal solid waste (OFMSW) as a substrate for Hermetia illucens larval growth and microalgae cultivation. The Excel-based analysis, which evaluated the mass and energy balance as well as the income statement, was integrated with a thematic analysis focused on exploring how the overall value attributed to the sustainabil...
