A well-functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi-structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing environmental consciousness and traditional reuse practices act as drivers. Policy barriers stem from the absence of dedicated CE regulations, though national sustainability efforts offer opportunities. Technological limitations arise from insufficient research, but efficiency-enhancing innovations and digital business models show promise. Economically, high transition costs hinder progress, whereas resource efficiency boosts competitiveness and job creation. Key priorities for advancing CE include raising public awareness, integrating CE into education, supporting waste pickers, developing decentralised regulations, improving waste management, fostering innovation hubs, and providing financial incentives for circular business models. Stakeholder engagement—particularly policy-makers, civil society, and private enterprises—remains essential to accelerating CE adoption in Brazil.

The marine ingredients (MIs) industry is essential to the aquaculture sector, mainly providing fishmeal and fish oil to support animal feed and human nutrition. The exponential growth of aquaculture and the heavy reliance on finite marine resources pose significant sustainability challenges and highlight the need for more comprehensive and regionally adapted metrics beyond current Life Cycle Assessment (LCA) indicators and non-conventional LCA metrics. In this systematic review, we analyzed 48 literature studies that focus on MIs sustainability using rigorous criteria for data quality and indicator relevance under the Prisma methodology. Our findings indicate that the studies that are mainly based on the LCA approach provide valuable insights into environmental performance, but are hindered by inconsistent metrics, limited data availability, and a lack of integration of economic, nutritional, and ethical dimensions in the sustainability analysis. Such limitations can lead to underestimate critical issues such as biodiversity loss, overfishing, and habitat degradation, while overemphasizing short-term efficiency measures, like feed conversion ratio, or environmental impacts such as global warming. Additionally, emerging novel proteins and alternative uses for fish-derived byproducts, ranging from direct human consumption to high-value applications (bioactive compounds, cosmetic, etc.), to other low-value products (like biofertilizers), remains largely unexplored, given the absence of holistic and flexible assessment tools. Thus, the presence of unregulated contaminants (including additives, antibiotics and microplastics), are not yet adequately addressed in most MIs studies, despite some recent methodological advancements. This review proposes the adoption of novel metrics, the standardization of assessment methods and the integration of multi-criteria decision analysis for LCA practitioners to better capture the complex and multifaceted challenges of MIs production, covering the way for more robust and reliable sustainability assessments within the aquaculture industry.
