Abstract

The global agricultural sector is confronting the dual challenge of ensuring food security for nearly 10 billion people by 2050 while drastically reducing its environmental footprint. The dominant linear “take, make, dispose” model, characterized by excessive freshwater use, intensive agrochemical inputs, and massive generation of organic residues, is no longer tenable. Industrial Symbiosis (IS) – the collaborative exchange of materials, energy, water, and by, products among co, located or networked firms – has emerged as a key paradigm to operationalize the circular bioeconomy. In agricultural contexts, often termed Agro, Industrial Symbiosis (Agro, IS), the biological nature of material flows, spatial dispersion of actors, and strong seasonal variability introduce complexities not encountered in classic industrial ecosystems. This review systematically examines the intersection of IS and Resource Flow Optimization (RFO) within agricultural sectors. It synthesizes the typologies of Agro, IS, evaluates core analytical methodologies including Material Flow Analysis (MFA), Life Cycle Assessment (LCA), and advanced mathematical optimization models, and surveys their application across nutrient recovery, bioenergy production, and biomass cascading. The review further identifies enduring barriers – spatial, temporal mismatches, biological variability, information asymmetry, and regulatory fragmentation – and discusses how digitalization, multi, scale optimization, and institutional innovation can overcome these hurdles. We argue that the transition from isolated pilot projects to systemic circularity demands not only technical and methodological sophistication but also transformative policy frameworks and collaborative governance structures.
