Abstract: The subject of the research is comparative analysis of production systems for the production of protein-containing products of the traditional type and the new production system: “New sericulture” (hereinafter referred to as “NS”), where the feeding products of a silkworm (Bombyx mori (L.): shell cocoon, processed into a functional food product (silk and amino acid peptides), and silkworm pupa, are used as an effective and cheap ingredient in animal and aquaculture feed. Production systems analysis, based on public data, is considered with account for all transformation stages: biosynthesis, bioconversion, and technical conversion, including deep technical conversion (proteins modification) right up to end products. The scientific novelty of the research consists in the detected comparable KPIs of all stages of production processes, such as: biosystem index, biosystem protein index, and income per agricultural ares unit, which help assess the effectiveness of material flow which is the basis of economic effectiveness. According to these criteria, significantly outstripping performance indicators of traditional production systems, “NS” can be considered as a sustainable alternative to the traditional types of protein-containing products manufacturing.
