Bridging the scale-up gap is critical for transforming marine waste-to-value innovations into commercially viable circular blue economy enterprises
Marine circular-economy enterprises are a vital component of the blue economy, converting marine waste such as fish and shell residues, marine biomass, and beach wrack into food, feed, pharmaceutical and cosmeceutical ingredients, and biodegradable materials. Globally, aquaculture and fisheries generate over 20 million tonnes of waste annually, with India alone producing about 2 million tonnes. Despite their substantial economic, social, and environmental benefits, scaling up these technologies from lab- or pilot-scale processes to a viable commercial model remains a significant challenge, limiting market success. Bridging this “scale-up gap” is essential for circular blue economy enterprises to move beyond proof-of-concept projects and become commercially successful, thereby attracting investment and generating environmental and livelihood benefits.
Marine circular ventures can contribute to decarbonisation through bio-based alternatives, food and nutrition security, and the development of new value chains, underscoring the need for coordinated efforts to scale them from sporadic pilots to industrial scale. Moreover, this scaling up is central to economic growth, job creation, resource utilisation, waste management and sustainable production. Financial and policy instruments, such as the Seychelles Blue Bond, help scale up sustainable blue marine projects, leading to resilient coastal livelihoods and accelerated growth of the blue economy.

Though the blue economy’s potential is widely recognised, its transition from pilot scale to a commercially viable process requires identifying and addressing interconnected governance, technical, and financial challenges. Coordinated and targeted policies can enable the growth of technology and the economy, catalysing socio-economic and environmental advancement. With the right policy impetus, scaling up the blue economy, including circular blue economy enterprises, can create up to 51 million additional jobs globally by 2050.
Marine enterprises rely on highly heterogeneous, seasonal feedstocks, such as fish, shell, and seaweed waste, causing a high degree of unpredictability across the supply chain. These feedstocks vary in biochemical composition (for example, protein 12-30 percent, lipid 0-25 percent in fish waste) across species, environment, and processing methods, directly affecting process design, yields and product quality. While laboratory- and pilot-scale systems can accommodate this variability through manual adjustments, industrial-scale systems lack this flexibility, resulting in reduced process efficiency, increased downtime, and higher operating costs. Weak supply chain logistics and poor waste segregation further dent investor confidence, further compounding these challenges. In many coastal regions, only 30-40 percent of marine waste is systematically collected and transformed into high-value products, while up to 70 percent is discarded or utilised for low-value applications.
Establishing an integrated marine biorefinery infrastructure requires US$2-5 million at a small scale and over US$80 million for commercial-scale production, creating a barrier where small-scale operations require higher per-unit investment, while large-scale production requires capital beyond the reach of early-stage startups. The primary constraint, thus, is not technological readiness but the absence of financing opportunities tailored to the current “translational” stage, which is too advanced for research grants and too risky for commercial investors. Energy requirements and costs strongly affect the economics of marine waste processing. Moreover, energy-intensive operations (drying, thermal processing, etc.) account for up to 40 percent of operating costs, and this figure increases with scale. Scaling up of waste-to-value processes, therefore, requires well-designed, integrated processing that balances efficiency, yield, cost effectiveness, and quality.

At present, a large share of marine waste-derived biochemicals target niche, high-value markets (nutraceuticals, cosmetics, pharmaceuticals and speciality chemicals), with an annual growth rate of 7-10 percent. However, they face regulatory barriers and long commercialisation timelines. In these segments, scaled processes are highly sensitive to feedstock prices and energy costs, although lower-value applications, such as animal feed and fertilisers, with higher market demand require lower production costs for scale-up. Thus, this gap between production capacity and market demand can leave facilities underutilised. Furthermore, fragmented marine waste regulation across multiple departments, such as environment, fisheries and industries, extends approval timelines by 12 to 24 months, increasing transaction costs. While food, feed and pharma-related applications face strict safety and quality regulations, the costs of testing, quality control, and certifications increase overall financial investment by 15-20 percent, making market sustainability challenging for small and medium enterprises (SMEs).
Additionally, the limited use of early-stage techno-economic assessment (TEA) poses a persistent challenge across all waste value addition ventures, with efforts prioritising technical feasibility and pilot-scale validation over commercial viability. This scenario often prompts early-stage investments in inefficient, economically unviable processes. Thus, integrating TEA and life cycle assessment (LCA) at the design stage would help identify economic and environmental feasibility, major cost and energy drivers, and viable scale-up thresholds, before committing major capital investments. Despite these advantages, these tools remain underutilised in the design of blue economy enterprises.

A shared cluster-based feedstock aggregation system for collection, segregation, cold-chain storage and pre-processing infrastructure can help reduce capital costs by up to 45 percent, and enable technically and economically viable industrial-scale processing. Initiatives, such as the Arctic Blue Circle and northern Europe’s Blue Circular Economy project, which promote shared cold-chain and pre-processing infrastructure while coordinating logistics, demonstrate how interconnected SME networks can encourage collaboration, innovation, and attract strategic investments to build a sustainable market to scale up blue economy enterprises.
Targeting the intermediate phase with tailored support mechanisms, such as scale-up grants, viability support, low-interest financing, and public-private co-investment, is key. Combining these factors with processing infrastructure clusters would help accelerate the transition to industrial-scale production. Circular economy initiatives such as the Osaka Blue Ocean vision illustrate how clear, long-term strategy, coordinated regulation and public-private partnerships can help bridge this funding gap.
As energy costs are a key barrier to the scaling of the energy-intensive marine bioprocessing sector, reducing energy intensity and costs by prioritising renewable energy (solar, waste heat recovery and biomass), targeted grants, shared infrastructure and energy cost subsidies is crucial. Iceland’s use of geothermal energy in seafood facilities and the European Union’s (EU) grants for renewable energy show how these approaches reduce scale-up costs and improve sustainability.
Regulatory pathways in the EU and Japan have demonstrated how production can be aligned with market demand, facilitating early scale-up, with lower regulatory barriers and faster approvals for high-value market entry. These strategic regulatory pathways have enabled faster commercialisation of bio-based materials, products, and novel foods, reducing market-entry timelines and attracting investment. Streamlining regulatory approvals through single-window systems, subsidies for certification, shared quality-testing facilities, and regulatory support is essential to accelerating the scale-up of marine waste-based SMEs.
Formally integrating TEA and LCA into funding decisions, blue economy policies, and investment approvals is essential to ensure that selected technologies for scale-up are both economically and environmentally viable. The EU has integrated TEA and LCA into funding frameworks and bioeconomy polices, aligned with the international standard framework (ISO/TS 14076:2025). Shared databases and targeted availability of finances prior to large-scale funding approvals can support such integration and reduce risks and financial losses.
Involving coastal communities, particularly youth and women, who are critical to waste collection, segregation, and local value addition through cooperatives and self-help groups, is essential to the success of marine waste-to-value enterprises. Research across Indian Ocean Rim Association (IORA) countries, as well as initiatives such as AmmachiLabs in India and women-led seaweed cooperatives in Kenya and the Philippines, have shown that providing adequate training and funding can effectively encourage women’s participation in blue economy ventures. Moreover, gender-inclusive innovation and support for scale-up in training, infrastructure and seed funding will further encourage women’s and youth’s participation.
Scaling up circular blue economy enterprises requires going beyond mere technological advancements. Coordination among coastal, environmental, and industrial policies, along with dedicated funding mechanisms, is necessary to overcome the regulatory and operational barriers. Unlocking the full potential of marine waste value-addition enterprises will also depend on creating an ecosystem for research, innovation, industries, coastal communities, and entrepreneurs with resilient business models that can adapt to a changing market environment.
