The European Union Regulation (EU) 2015/2283 on novel foods has created new opportunities for the valorization of marine by-products within the framework of the circular bioeconomy and sustainable blue economy. Refined shrimp peptide concentrate (RSPC), obtained through enzymatic hydrolysis of Pandalus borealis shells and heads, represents a relevant case study for examining the interaction between food innovation, regulatory assessment, sustainability, and value-chain development. This study analyzes the EFSA scientific opinion on RSPC and reviews available compositional, toxicological, allergenicity, and clinical evidence, contextualizing the ingredient within European policies on circular economy, resource efficiency, and sustainable food systems. The assessment indicates that RSPC consists mainly of 8 low-molecular-weight peptides with demonstrated angiotensin-converting enzyme (ACE) inhibitory activity and potential applications in blood pressure management. Beyond its functional properties, the valorization of shrimp processing by-products offers opportunities to reduce waste generation, increase resource efficiency, and create new economic value within the seafood sector. The case study highlights how the novel food regulatory framework can support the safe market introduction of innovative marine-derived ingredients while contributing to circular economy objectives. Although challenges related to allergenicity management, consumer acceptance, and industrial scalability remain, RSPC demonstrates the potential of marine by-product valorization to foster more sustainable, resilient, and economically viable food systems.

Convective fruit drying is energy-intensive and a major greenhouse gas (GHG) source in the agri-food sector. Existing carbon footprint (CF) studies are fragmented, separating emissions accounting from economic performance and quality verification, limiting their usefulness for small and medium-sized enterprises (SMEs) seeking practical decarbonization actions. This study proposes an integrated, verification-oriented framework linking organizational carbon accounting, process engineering, and product quality within a unified decision platform. The framework combines (i) GHG quantification (ISO 14064-1:2018 and ISO 14067:2018); (ii) techno-economic modeling via process simulation; (iii) experimental validation of quality attributes (moisture, water activity, color, texture); and (iv) sensitivity analysis. The framework was applied to four energy configurations: baseline and three decarbonization scenarios (solar thermal, photovoltaic (PV), and combined). The baseline footprint was 139,090 kg CO₂e (±11.43%). Emission reductions ranged from 15.05% to 34.73%, with the combined solar-PV configuration achieving the highest mitigation while maintaining commercial quality. Emission intensity dropped from 1.19 to 0.78 kg CO₂e per functional unit. Economic performance showed payback periods of 5.78–10.54 years and IRRs of 15.8–24.2%. This framework provides a transferable tool for SMEs to prioritize decarbonization strategies based on integrated environmental, economic, and quality criteria. Full article

This paper explores the potential for promoting Ethiopian teff flour through the European Union’s Geographical Indications (GI) framework. After outlining the evolution of GI regulations in the international trade context and the EU’s role in quality policy for agri-food products, the paper assesses the value of teff as a high-potential product. Originated and domesticated around Axum, teff is a staple crop in Ethiopia, both nutritionally and socio-economically, cultivated by a multitude of smallholder farmers. However, access to European markets is hindered by insufficient enforcement of food safety standards, lack of quality control, and inconsistent labelling practices. Recognition as a GI—specifically as a Protected Geographical Indication (PGI)—could enhance the visibility, traceability, and legal protection of Ethiopia’s teff. The paper also highlights challenges in advocating for the development of a detailed product specification aligned with EU regulations. Integrating teff production into the GI system may strengthen rural economies, preserve traditional knowledge, and increase the international profile of a product with significant nutritional and economic potential.

The transition towards a circular economy of agri-food wastes requires innovative strategies for transforming them into value-added products. This study evaluates the environmental and economic sustainability of a laboratory-scale process that converts 100 g of pomegranate waste, experimentally processed and defined as functional unit (FU), into a cosmetic emulsion. Primary data were collected from laboratory activities carried out in an Italian university, including material and reagent consumption, equipment operating times and energy use. A cradle-to-gate Life Cycle Assessment was performed in SimaPro according to ISO 14040 and 14044 using the Environmental Footprint 3.1 method, while Life Cycle Costing was developed in Microsoft Excel using the same system boundaries. The process valorized the three main pomegranate fractions (arils, mesocarp and exocarp) to obtain a cosmetic emulsion. The exocarp treatment was identified as the main impactful phase. The overall climate change impact reached 328 g CO₂ eq/FU, while fossil resource use amounted to 5.3 MJ/FU. The total production cost was estimated at 189 €/FU, mainly due to labor, reagents, enzymes and equipment costs. Although laboratory-scale operation results in relatively high impacts and costs, the study identifies the main hotspots and provides a baseline for future process optimization and industrial scale-up.

In this study, biochars derived from agri-food wastes, including different avocado residues (peel- and seed-derived fractions), olive pits and cherry stones, were evaluated as low-cost and sustainable adsorbents for the removal of the emerging contaminants sulfamethoxazole (SMX), antipyrine (ANT) and trazodone (TRZ) from aqueous solutions. Despite their very low BET surface areas, the biochars exhibited notable adsorption capacities, indicating that adsorption performance was mainly governed by surface chemistry rather than textural properties. FTIR analysis confirmed the presence of abundant oxygen-containing functional groups on the biochar surfaces, enabling electrostatic interactions, hydrogen bonding and dipole–dipole interactions with the target contaminants. Adsorption kinetics for all systems were well described by the pseudo-first-order model, with equilibrium capacities closely matching experimental values, suggesting rapid and reversible surface interactions. Intraparticle diffusion analysis revealed that diffusion was not the sole rate-limiting step, with external mass transfer and surface interactions dominating the initial adsorption stage. Equilibrium isotherm analysis showed that SMX and ANT adsorption onto avocado-derived biochars followed the Langmuir model, whereas TRZ adsorption was better described by the Freundlich model. In contrast, olive pit biochar exhibited a markedly higher affinity for TRZ, achieving near-complete removal and fitting the Langmuir isotherm. Finally, high removal efficiencies were maintained when applying the selected biochar to real municipal wastewater, demonstrating robustness under complex matrix conditions. Overall, the results highlight the potential of these agri-food waste-derived biochars, including multiple avocado fractions, as sustainable and economically viable adsorbents for quaternary wastewater treatment.

Ensuring the sustainability of agriculture-related industries requires not only expanding value added but also maintaining stable value creation and adaptive capacity under changing economic conditions. This study examines the economic and organizational sustainability of China’s agriculture-related industries within global value chains. Using the 2026 release of the OECD Analytical Activities of Multinational Enterprises database and ownership-split inter-country input–output tables for 2011–2023, we construct an ownership-disaggregated value-added accounting framework covering the production, processing, and circulation stages and apply structural decomposition analysis to identify the sources of value-added change and potential weak links. The results show that domestic demand is the principal source of value creation for both domestic-owned and foreign-owned enterprises and became increasingly important over the study period. Final-goods-related value added remains larger than intermediate-goods-related value added, although the latter grows more rapidly, indicating deeper participation in cross-border production networks. Structural exposure varies across stages and periods. Production is strongly supported by domestic demand but exhibits pronounced internal offsetting in some periods; processing becomes a major adjustment node during 2019–2020, while circulation records the clearest contraction in the same period before returning to a more balanced growth structure during 2020–2023. Foreign-owned enterprises, particularly in processing, become increasingly embedded in China’s domestic market and local production structure. Risk exposure is interpreted as structural sensitivity rather than a direct measure of risk probability or expected loss. The findings highlight the importance of domestic demand, diversified input and market linkages, greater stability and adaptability in processing and circulation, and well-governed cross-ownership relationships for sustainable value-chain development.

The study presents methodological approaches to developing regional agri-food strategies integrating economic, social, and environmental indicators, aiming to improve socio-economic and environmental efficiency in the context of food security. To assess regional sustainable development, a hierarchical cluster analysis using Ward’s method was applied to compare Russian regions based on indicators of agricultural specialization, economic efficiency, food security, social conditions, and environmental impact. The analysis identified seven distinct regional clusters with significant socio-economic and environmental differences. A critical finding is that all clusters exhibit persistent problems with waste disposal and neutralization, alongside an acute shortage of investment for technological modernization and additional processing capacity. Key priorities for improving efficiency in achieving food security are identified, and differentiated sustainable development strategies for the selected groups are proposed, including recommendations for adapting governance mechanisms and state support. The need for fundamentally new forms of financing innovative businesses is substantiated. This study provides a differentiated framework for developing regulatory tools for regional agri-food systems based on cluster analysis results. The findings have practical value for planning socio-economic and environmental development programs and for formulating state innovation policy in agricultural support. Full article

Ensuring local and sustainable food security is gaining an important role in rural development strategies at national and regional scales in Europe. This relies to an important degree upon the implementation of new, or old, agri-environmental policy, namely, policies at the intersection of agriculture and the environment. Yet, the incorporation of agri-environmental policy in rural development strategies at the regional level creates, and often accelerates, contradictions between existing rural development paths and the structural changes needed to achieve both environmental objectives and economically viable agricultural development. Within this context, agroecological transitions are framed as key for transformations of national food systems. However, understanding the prospects and barriers for agroecological transitions and food security at the regional level requires a much deeper understanding of how national and international food policies shape and are shaped by long political economic trajectories of rural development with competing interests. In this paper, we explore these contradictions of rural development in Europe by comparatively analyzing the political nature of potential agroecological transitions in Europe and how these transitions interact with agri-environmental policies and rural development strategies at the regional level.

The fruit agro-export value chain in northern Chile faces governance and water-related challenges that affect its resilience and long-term sustainability. In the context of sustainable agriculture, these challenges highlight the need for integrated approaches to understand how socio-economic and environmental factors interact. This paper proposes a set of measures to assess resilience using a social simulation model based on the Sociology of Organized Action, implemented through the Social Laboratory (SocLab) platform. The model represents actors, their resources, and their interactions as a system driven by strategic behavior. The proposed measures are applied to analyze both simulation outcomes and the structure of the model. The findings indicate that resilience is constrained by power imbalances among actors and by external pressures related to water scarcity. In particular, simulation results show that the influence of Producers reaches only approximately half that of the Public Sector, revealing a significant power imbalance within the value chain. These imbalances create vulnerabilities that limit the system’s capacity to absorb disturbances and adapt to environmental stressors, which are expected to intensify due to climate change and increasing demand. In addition, the resource associated with coordinating actors around the efficient use of water exhibited the highest relevance among the resources considered, highlighting the central role of water governance in shaping resilience. The study contributes by integrating a simulation-based approach with economic and institutional perspectives, linking the distribution of influence among actors to value allocation along the chain, as conceptualized in marketing margin analysis, and interpreting governance structures through Transaction Cost Economics. This integration provides a more comprehensive understanding of how power distribution, coordination mechanisms, and transaction costs jointly shape resilience and sustainability in agri-food value chains.

Food loss and waste (FLW) constitutes a structural challenge for agri-food systems. However, current analytical tools for assessing management and valorisation options remain fragmented across disciplines. Existing frameworks rarely capture within a single structure the environmental, social, and economic–institutional feasibility dimensions needed to compare alternative recovery pathways. This study introduces the ESG-FLW Index, a multidimensional composite index designed to support comparative evaluation of FLW valorisation strategies, with particular attention to recovery for human consumption. The index draws on a comparative analysis of eight established frameworks. It integrates Life Cycle Assessment for the environmental pillar; Techno-Economic Assessment together with compliance, data-quality, scalability, and replicability indicators for the governance pillar; and Social Return on Investment for the social pillar. These components are aggregated through Multi-Criteria Decision Analysis, following methodological guidance for robust composite indicators. The framework aligns explicitly with the Food Waste Hierarchy and SDG Target 12.3. It also includes hurdle criteria to limit the risk that high aggregate scores obscure critical shortcomings. As a proof of concept, the index was applied to the CiboAmico redistribution programme. Redistribution scored substantially higher than composting (85.1 versus 30.7). The ranking remained stable under ±20% weight variations and Monte Carlo simulations (n = 1000). The ESG-FLW Index offers a transparent and replicable decision-support tool. It is best suited to relative comparison among options and to making sustainability trade-offs explicit. Full article

Achieving energy sustainability is a major challenge across all sectors of an economy. In agri-food systems (AFSs), this challenge is twofold in the context of energy sustainability; one challenge is to reduce fossil fuel dependency, and another challenge is to provide safe and nutritious food for humans and animals. An appropriate aggregate indicator needs to be used for assessing the energy sustainability of AFSs. This study presents a systematic literature review aimed at developing a core indicators framework to support both research and policymaking. It also critically evaluates and updates existing indicators currently used to evaluate energy sustainability in AFSs, considering environmental, economic, social and technical dimensions. Environmental indicators, such as energy use efficiency, net energy balance, carbon footprint, exergy destruction and renewable energy share, measure the ecological impacts of agricultural practices. Economic indicators, including energy cost share, levelized cost of energy, energy return on investment, and productivity per unit of energy input, reflect how energy use influences farm competitiveness and resilience. Social indicators such as equitable access to energy, labor productivity gains, and system resilience to energy shocks highlight the broader human and societal aspects of energy sustainability. Technical indicators, including technology performance, maintenance intensity, technology lifespan, and resource circularity, emphasize the need to minimize resource depletion and environmental harm. Together, these sustainability indicators provide a strong framework for assessing trade-offs and guiding policy decisions that support the transition toward low-carbon, resilient, and resource-efficient AFSs. Their effective development and implementation require interdisciplinary knowledge integration and active engagement with relevant societal stakeholders in a transdisciplinary sustainability context.

Agri-food byproducts are increasingly investigated as food-tech material resources, but compositional richness alone does not establish ingredient suitability. This critical narrative review evaluates plant-derived and processing residues across four representative material groups: fiber- and polysaccharide-rich powders and fractions, protein- and starch-rich materials, bioprocessed ingredients, and formulation-supporting composites. We examine how source identity, stabilization, drying, milling, fermentation, enzymatic modification, fractionation, and formulation influence hydration, interfacial behavior, gelation, rheology, texture, sensory compatibility, storage stability, and preservation-supporting performance. Evidence is interpreted across linked feedstock–processing–functionality–application–readiness gates, with separate consideration of safety, regulatory positioning, batch specifications, scale-up, techno-economic feasibility, life cycle assessment, and circularity boundaries. The practical output is a five-gate decision support and claim calibration framework that distinguishes four proposed evidence levels: Candidate, Functionality-supported, Formulation-validated, and Industry-ready potential. As a proposed non-numerical synthesis, the framework supports decision-making and claim calibration rather than ranking, certification, or regulatory approval; it identifies the evidence required before matrix-specific functional, safety, sustainability, or industry relevance claims are made.

Food waste has emerged as one of the most pressing global sustainability challenges because of its environmental, economic, and social implications. Nearly one-third of the food produced worldwide is lost or wasted each year, contributing to greenhouse gas emissions, depletion of natural resources, and increasing food insecurity. Advances in circular bioeconomy concepts and sustainable processing technologies have transformed food waste from an environmental liability into a valuable feedstock for producing biofuels, bioplastics, bioactive compounds, functional ingredients, prebiotics, and other high-value products. This review critically examines current strategies for converting food waste into value-added products, including green extraction technologies and biochemical, thermochemical, enzymatic, and microbial approaches. Attention is given to major agri-food by-products, such as fruit pomace, vegetable residues, oilseed meals, dairy by-products, and agro-industrial wastes. Emerging developments involving biorefinery concepts, artificial intelligence, digital biorefineries, synthetic biology, and carbon-neutral production systems are also discussed. Furthermore, the review highlights recent applications of waste-derived fibers, antioxidants, and polyphenols in functional foods, especially bakery products. Finally, key challenges related to feedstock heterogeneity, process scalability, regulatory frameworks, economic feasibility, and sustainability assessment are critically analyzed together with future research directions supporting the transition toward resilient circular bioeconomy systems.

China’s growing demand for fruit has accelerated the expansion of China-centered agrifood production networks across Southeast Asia. This study examines the integration of Cambodia’s banana export industry into this network from a global production network perspective. Drawing on fieldwork conducted in Cambodia between 2023 and 2025, including participant observation, interviews, and worker surveys, the study analyzes lead firms, governance arrangements, labor organization, and value distribution. Chinese agribusiness firms serve as lead firms. Governance is facilitated by economic land concessions, bilateral phytosanitary agreements, the Belt and Road Initiative, and the Cambodia Banana Industry Association Federation. The network is characterized by low-wage and highly mobile labor, reflecting tensions between plantation management and workers’ livelihood strategies. Although Cambodia has been integrated into the network as an export-oriented production base, value enhancement has not necessarily translated into greater value capture and remains concentrated in downstream distribution and retail. This study argues that China-centered agrifood production networks reproduce the unequal value distribution observed in established banana commodity chains. Although based on a qualitative single-case study in Cambodia, the findings provide empirical insights into the governance and developmental implications of China-centered agrifood production networks and offer a foundation for future comparative research.

Background: Perishable agri-food supply chains require logistics networks that remain economically viable despite fluctuations in demand, transportation costs, and market prices. This study develops and evaluates a two-echelon logistics network for the banana supply chain in Magdalena, Colombia. Methods: A mixed-integer linear programming model was formulated to maximise daily profit by jointly determining collection-centre activation and product flows among 14 producers, five candidate collection centres, and two commercial buyers. The deterministic solution was complemented by sensitivity analysis and 1000 Monte Carlo optimisation scenarios incorporating variability in demand, transportation costs, and selling prices. Results: Under nominal conditions, all five collection centres were activated, the full demand of 42,000 kg/day was served, and the optimal profit was USD 3093/day. Centres C1–C4 operated at full capacity, whereas C5 reached 42.9% utilization. Under uncertainty, the mean profit decreased to USD 1955.70/day, the mean unmet demand was 954.03 kg/day, and shortages occurred in 72.3% of scenarios. C1–C4 remained the network core, while C5 acted as a flexible contingency facility. Conclusions: The proposed framework reveals an efficiency–resilience trade-off overlooked by deterministic optimisation. Demand growth and capacity reductions are the principal operational risks, supporting investment in collection capacity and proactive demand management. Full article
