Introduction: An Innovative Roadmap to Blue Economy

The World Bank defines ‘blue economy’ as the “sustainable use of ocean resources for economic growth, improved livelihoods and jobs while preserving the health of the ocean ecosystem.”^[1] India, with its vast coastline of 11,098.8 km and rich marine ecosystems, has immense potential for generating significant economic returns from the blue economy.^[2] At present, the blue economy accounts for approximately 4 percent of India’s GDP.^[3] Recognising this contribution, the country aims to build a US$100-billion blue economy by 2030, centred around the responsible exploration of ocean resources, such as minerals, as envisaged under the Deep Ocean Mission launched in 2021.^[4],[5]

Marine waste encompasses a wide range of materials, including plastics, metals, paper and wood, ceramics, glass, rubber, ship and fishing gear, chemicals, household waste, industrial waste, organic waste, and biomass waste.^[6] Marine biomass waste is a subcategory consisting of organic waste and biological materials, like seaweed, fish residues, shells, and other biological waste, posing a barrier to harnessing the potential of this resource and understanding its impact on policy. Marine waste, which costs the global economy US$20 billion annually, is projected to reach US$731 billion by 2050. Of the six to eight million tonnes of marine biomass waste, including waste from crab, lobster, and shrimp shells produced annually, South Asia contributes approximately 1.5 million tonnes.^[7]

India generates a substantial quantity of marine biomass waste, comprising up to 50 percent fish waste, 80,000 tonnes of shellfish waste, 34,000 tonnes of seaweed, and beach wrack (organic material, such as seaweed, shells, and seagrass, deposited on beaches).^[8] In the developed countries, the disposal of one tonne of such waste can cost up to US$150.^[9] In Mexico, cleaning sargassum from beaches is estimated to cost at least US$37 million in 2019.^[10] Seaweed cleanup costs US$1 million per kilometre of coast in 2023.^[11] The 2018 cleanup activities on the Caribbean coast were reported to cost US$120 million, and 54 million euros from 2015 to 2023 in France.^[12] Most of this waste is either dumped back into the ocean or into landfills, contributing to pollution, oxygen depletion, and the spread of pathogens.

The ambitious roadmap to make India one of the world’s leading blue economies requires a paradigm shift in how waste management is carried out. The transition to the circular economy model, which reimagines waste as a resource rather than a burden (Figure 1) is a pillar to achieving this.

With the right approach, this waste can drive innovation and new value chains. The traditional linear economy approach of “extract-product-discard” is no longer viable, as it generates an escalated waste burden downstream. A circular economy approach, with the waste-to-wealth concept at its core and guided by systems thinking, offers a sustainable alternative to reduce waste across the value chain.^[13] This approach entails converting marine waste into value-added products, driving innovation and sustainability, and focusing on sustainable production and consumption to garner economic and environmental benefits.^[14]

Transitioning to a circular blue economy can lower the costs of raw materials and technology, saving the global economy US$2.9 trillion, while generating vast employment opportunities by 2030.^[15] Globally, marine biomass waste represents an opportunity to generate revenues of up to US$30-40 billion annually (approximately US$1-2 billion for India), considering the avoided disposal costs.^[16]

Reimagining India’s marine biomass waste into valuable resources using a circular economy approach is, therefore, not only environmentally beneficial but also a substantial economic opportunity with multiple benefits. The proposed blue circular economy policy framework aligns with a number of UN Sustainable Development Goals, including SDG1 (No Poverty), SDG2 (Zero Hunger), SDG 5 (Gender Equality), SDG 7 (Affordable and Clean Energy), SDG 8 (Decent Work and Economic Growth), SDG 9 (Industry, Innovation, and Infrastructure), SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action), and SDG 14 (Life Below Water).^[17] With this approach, India can achieve its waste management goals, generate new value chains, and create new employment opportunities, ultimately realising its US$100-billion blue economy vision.

Marine Biomass Waste: From Burden to Opportunity

Approximately 35 percent of global marine harvests are discarded as waste each year.^[18] This represents a dual challenge: lost economic potential and a massive environmental burden. Marine biomass waste includes approximately 134 million tonnes of fish waste,^[19] 20 million tonnes of harvest loss, 0.1-325 kilograms per meter coastline beach wrack,^[20] 8-10 million tonnes of crustacean and mollusc shells, and 33 million tonnes of seaweed with residues^[21] (see Figure 2).

For India, with more than 20 million people dependent on fisheries, these waste streams represent the untapped potential to generate new livelihood opportunities and value-added products^[23] (Table 1).

Table 1: Marine Biomass Waste in India: Production, Composition, and Potential Markets

Biomass Type	Annual Production in India	Potential Products Based on Composition (dry basis)[24]	Energy Value (HHV, MJ/kg)[25]	Market for Potential Products	Key Takeaways
Fish waste (viscera, bones, skin, etc.)	~2 MMT (large volume)[26]	Fixed carbon (FC): 7-17 percent (Moderate – some potential for biochar); Volatile Matter (VM): 67-91 percent (High – good for extracting proteins and oils); Ash: 2-17 percent (Low to Moderate – Minimum mineral content, improved ease of processing)	19-22 (High – suitable for conversion to biofuel and biochar)	Food and feed supplements, nutraceuticals, pharmaceuticals, cosmetics, and renewable energy	High VM and HHV indicate that fish waste is a rich source of biochemicals and fuels. Small processing units are needed for storage and value retention.
Microalgae	36,900 tonnes (small, but scalable)[27]	FC: 2-28 percent (Can form hydrochar), VM: 57-89 percent (High biochemical content – good for biofuels, pigments, biopolymers, and  biomaterials), Ash: 7-26 percent (High – affects conversion to fuels)	18-24 (High – suitable for conversion to biofuels and bioplastics)	Nutraceuticals and Functional Foods, Renewable Energy, Biodegradable Packaging, Pharmaceuticals	High VM and HHV indicate the suitability of microalgae for conversion to fuels and biochemicals. Collection frameworks and R&D support are required.
Macroalgae	33,345 tonnes wet weight[28]	FC: 9-22 percent (Low to Moderate); VM: 45-77 percent (Moderate to High – Good for biomaterials and biochemicals); Ash: 8-43 percent	13-22 (Moderate – suitable for polysaccharides and gel extraction, not great for biofuels)	Gelling agents in the food industry, Nutraceuticals and Pharmaceuticals, Biodegradable packaging, and Renewable energy	Moderate HHV and high ash content indicate potential for gels and nutraceuticals, which can support coastal livelihoods, especially those of women, through fair pricing and support.
Shrimp/ Shellfish waste	80,000 tonnes (significant)[29]	FC: <1 percent (Low – not suitable for char); VM: 50-60 percent (Moderate – biochemicals and organic materials); Ash: up to 99 percent (very high – mostly minerals like calcium carbonate)	<10 (low – poor for biofuels)	Wound dressing and drug-delivery materials, Nutraceuticals, Cosmetics, and Animal feed	High ash and low HHV content of shell waste indicate its potential for biomaterial extraction, such as medical-grade chitosan. Small-scale extraction units and a standard treatment plan to avoid contamination are necessary.

Seaweed valorisation, for one, is receiving global attention for its role in the circular economy, due to its immense environmental and economic benefits, the absence of chemical or pesticide requirements, and the minimal arable land required for growth. The global seaweed industry is projected to reach US$12 billion by 2030.^[30] Globally, 500 million tonnes of seaweed can absorb 135 million tonnes of carbon (equivalent to 6 percent of carbon added to oceans), generate methane and biofuel worth 1.25 billion megawatt-hours of energy annually (equivalent to 1 percent of global energy use), and create 50 million primary jobs and 100 million secondary jobs every year.^[31]

In India, seaweed biomass can sequester approximately 9,052 tonnes of CO₂ per day, resulting in a daily net carbon credit of 8,687 tonnes per day.^[32] NITI Aayog estimates that ~10 million hectares of production can generate INR 1.328 crore annually, provide jobs to 50 million people, contribute to India’s GDP, produce 6.6 billion litres of biofuel, and sequester millions of tons of CO_2.^[33] Additionally, seaweed has the potential to completely replace fishmeal in animal feeds, reduce dependence on synthetic fertilisers, spare six percent of cropland, and 14 percent of freshwater globally. Strengthening policies and infrastructure can help India tap into this potential and achieve economic growth, and employment, climate, and sustainability goals.

India has launched various blue economy initiatives, including the Blue Economy 2.0 framework,^[34] the green hydrogen pilot plant,^[35] the hybrid renewable corridor,^[36] and the PM Matsya Sampada Yojana,^[37] which focus on sustainable aspects such as renewable energy, green shipping, and marine biotechnology. However, marine plastics, effluents, marine residues, and ghost gear are still considered environmental burdens, rather than valuable secondary resource streams. By employing the appropriate circular economy strategies, these materials can be transformed into recycled polymers, textiles, composites, biofertilisers, bioactive compounds, biopolymers, biofuels, animal feed, and industrial chemicals, thereby directly linking India’s ocean waste management to its decarbonisation efforts.

Norway, the United Kingdom (UK), and Canada are examples of countries with efficient policies that support sustainable marine biomass utilisation. Their policies actively support innovations and investments for marine biomass utilisation under “blue growth” initiatives.^[38] Nordic countries, with abundant biomass resources, have implemented policies that focus on food and feed ingredients, biofuels, biochemicals, and novel biomaterials derived from marine biomass.^[39]

India could develop integrated policies for marine waste streams with incentives for valorisation, similar to the EU’s regulatory framework, like the Waste Framework Directive^[40] and the Common Fisheries Policy,^[41] China’s Fisheries and Marine Environment Protection Law,^[42] and the US National Ocean Policy for the utilisation of marine by-products, biomass waste recycling, and integration of circular economy principles.^[43] India’s participation in intergovernmental and multilateral organisations such as the International Seabed Authority (ISA) and the Indian Ocean Rim Association (IORA) provides opportunities for collaborative research, technology transfer, and sustainable marine resource management. Table 2 summarises key examples of international policies on marine resources and their lessons for India.

Table 2:  Select Policies and Key Takeaways for India

Gap	Why It Matters	International Examples	Key Takeaways for India
A single national-level nodal agency for marine biomass valorisation	Fragmentation across ministries causes delays, duplication, and unclear guidelines	Seychelles has a dedicated Department of Blue Economy with a clear vision for the utilisation of ocean resources.[44] The Ministry of Ocean Economy and Fisheries in Mauritius provides a single institutional framework to bring together fisheries and the blue economy.[45]	India can adopt a similar unified framework with a single nodal agency for streamlined governance and biomass waste utilisation.
Marine waste collection and segregation	Mandatory biomass collection, segregation, and recycling are necessary	The EU’s waste framework[46] and common fisheries policy[47] mandates the tracking and disposal of all marine waste through post-based facilities.	India can mandate and provide incentives for waste collection and segregation at beaches and ports, involving local communities, as well as fund cold chain facilities for fish waste. Additionally, it can apply mobile app-based tracking systems.
Coastal biorefineries and pilot-scale facilities	Processing of waste near collection points will avoid spoilage and ensure efficient valorisation.	Norway’s blue bioeconomy and the EU’s BlueBio Cluster project focus on developing regional hubs that bring together industries, startups, research centres, and local communities. This effort involves value chain mapping to connect farmers, processors, and policymakers, as well as the implementation of monitoring and reporting systems.[48]	India can establish regional biorefinery hubs with shared laboratory and pilot-scale facilities, along with adequate funding mechanisms.
Ocean innovation clusters	Inadequate support for the scaling up of innovative technologies stops their commercialisation.	Canada’s ocean innovation cluster brings together industries, startups, research institutions, and governments to commercialise sustainable ocean-based technologies.[49]	Establish ocean innovation clusters within research institutions and provide sufficient funding and support for technology transfer and commercialisation.
Blue carbon	Monetising carbon capture and sequestration is necessary for revenue generation and the encouragement of carbon sequestration	Japan’s blue carbon initiative focuses on carbon finance and carbon credits.[50]	India can implement carbon credit schemes for blue carbon capture and sequestration.
Skill development and training programmes for coastal communities (women-focused)	Social inclusion and skill development are important for equitable benefits.	The Mareskill project, a collaborative initiative by the EU, focuses on addressing the skill gap in blue economy sectors.[51]	India can build organised industry and academia-led training programmes focused on coastal communities, youth, and women.
Mandatory techno economics (TEA) and life cycle assessment (LCA)	These studies are necessary for assessing the viability of innovations before scaling up for funding.	The Global CO2 Initiative’s toolkit provides support and funding for TEA and LCA analysis to assess project viability and scale-up potential.[52]	India can mandate and develop similar initiatives for funding TEA and LCA analysis before funding approval for scale-up

Global and Indian Initiatives for Marine Biomass Waste Valorisation

Certain global best practices, including China’s “Blue Circle” initiative, highlight the potential of valorising marine waste for the extraction of high-value products using Internet of Things (IoT) and blockchain for sorting, tracking, and pre-processing plastic waste, thereby establishing marine waste as a resource rather than waste.^[53] This system of converting waste into products applicable in the textile, composites, and packaging industries helps reduce marine plastic pollution and create livelihoods for coastal communities.^[54] The initiative has reduced carbon emissions by up to 2,930 tonnes and supported more than 6,000 low-income residents and fisherfolk.^[55] The annual income of frontline collectors increased by US$1,846, and fishers could access over US$13.8 million through low-interest green loans.^[56]

Various initiatives in different parts of the world currently focus on marine waste management using a circular economy approach. Some examples include the SARGEX project, which focuses on converting seaweed to biogas, biochar, and high-value bioproducts.^[57] . The EU-funded MINERVA project,^[58] which focuses on the conversion of seaweed to products useful in cosmetics and food-based applications, and the BluePoint project are other pertinent examples.^[59] The latter is an Atlantic/European initiative, focusing on the circular economy of marine plastics.

Estimates have projected Australia’s seaweed production and associated industries to contribute a market value of A$5-10 billion for seaweed-derived products, A$4.6 billion to its GDP, and 17,400 full-time jobs by 2050.^[60] Indonesia’s policy on seaweed valorisation aims to encourage seaweed farming and focus on the circular economy (utilisation of seaweed-based products for bioplastics, biofertilisers and animal feed).^[61] Globally, there are more than 150 startups working on seaweed and algae alone, with products applicable in biofuel, agriculture, cosmetics, nutraceuticals, packaging, and food.^[62]

With around eight active startups in India, apart from other blue economy-based startups, ocean waste valorisation presents an enormous entrepreneurial opportunity for the country.^[63] This shows that marine waste, when integrated into circular value chains, can drive sustainable economic growth. Promoting the valorisation of marine biomass waste can position India as a competitive producer of biodegradable materials, reduce pollution, and create more employment opportunities.

Although India has not yet adopted a nationwide model, digital ocean waste tracking platforms like Recykal,^[64] Samudra Manthan cleanup drives,^[65] emerging IoT pilots,^[66] and community engagement show its potential to utilise marine waste as an asset, holding great promise.^[67] Key government initiatives in marine biotechnology and blue innovation include the National Biotechnology Development Strategy 2021-25 for funding marine biotechnology,^[68] the Deep Ocean Mission (Bioprospecting) for identifying novel compounds,^[69] the BioRRAP portal for streamlining regulatory approvals,^[70] the Blue Revolution Scheme to promote seaweed farming,^[71] and the Atal Innovation Mission to support, among others, blue-tech startups.^[72] These initiatives have resulted in substantial implications such as funding for R&D projects, leading to the growth of biotech exports to INR 3,500 crore, reduced regulatory processing time by 30 percent, and enhanced seaweed production by 5 percent. It has also led to the establishment of 10 seaweed farms and supported 30 startups with 12 commercialised products, catalysing the development of algae-based carbon solutions and spurring the creation of 10,000 skilled jobs.^[73]

Several startups and social enterprises are working on the idea of marine waste management through valorisation. Notably, women lead nearly 40 percent of climate and circular economy-based startups in India.^[74] Zerocircle, a women-led startup in Maharashtra, aims to convert seaweed from the coasts of Gujarat and Tamil Nadu into ocean-safe, biodegradable packaging materials and films. Sea6 Energy, a Bengaluru-based startup, develops sustainable energy, food, and agriculture solutions using seaweed.

Women-led initiatives have twofold advantages, both in terms of environmental impact and social empowerment. Their leadership fosters greater inclusion, community engagement, and social outcomes, including more employment opportunities for women from marginalised communities.^[75] This indicates how global initiatives focusing on circular value chains, digital tools, and gender-inclusive enterprises can drive sustainable blue growth.

Key Challenges

The circular blue economy approach faces several challenges: inadequate cold storage, inefficient waste collection and segregation, poor processing facilities, regulatory constraints, and market entry limitations.^[76] The absence of cold chain infrastructure makes collecting, storing, and transporting biomass to value-added facilities challenging, resulting in the loss of perishable biomass, such as fish and fish products.^[77]

Waste heterogeneity (mixed biomass, plastic, fishing gear, industrial, household, and other types of waste) adds to process complexity due to its varying physical, chemical, and biological properties, resulting in different processing requirements for various types of waste, such as storage, drying, processing, and purification steps. Some19-23 million tonnes of plastic waste leak into the aquatic ecosystem annually; this is projected to increase to 23-37 million tonnes by 2040.^[78] India alone generates more than two million tonnes of marine plastic waste, which often gets mixed with marine biomass waste.^[79]

Inconsistency in feedstock supply, including quality and quantity, affects both the scaling up of valorisation technology, which in turn impacts the target product yield and quality. The type, origin, and environmental conditions of the feedstock determine the chemical composition of different kinds of marine biomass.^[80] Industrial valorisation processes often require a consistent chemical composition of feedstock to standardise the operating conditions, such as temperature, humidity, pH, reaction time, and chemical or biological process.^[81] Therefore, certification protocols for standardising feedstock quality are essential.

Moreover, community engagement, including that of fishers and coastal communities, is critical to success.^[82] Focused regulatory frameworks and community awareness are necessary for utilising marine products in the food and pharmaceutical industries and overcoming their market entry limitations.^[83] Many promising innovations fail to progress beyond proof-of-concept and pilot stage due to inadequate facilities, skilled operators, logistics, and funding for scale-up.^[84] Currently, the commercialisation of marine biotechnology innovations is limited due to a dependence on imported equipment and a lack of research and scale-up infrastructure.^[85] Most funding is directed towards finished products, whereas scale-up studies (from lab to pilot scale) are imperative to make the products market-ready.^[86] Additionally, the timelines provided by most funding schemes (6-12 months) to complete the scale-up studies are inadequate to generate the necessary data. Addressing these challenges through key policy changes could unlock the full potential of India’s blue economy.

Policy Recommendations

India’s current policy framework faces gaps due to inadequate infrastructure, limited support and funding for research and innovation, and poor integration of circular economy strategies.^[87]

Table 3: Policy Pillars and Focus Areas for Marine Biomass Waste Valorisation in India

Policy Pillars	Focus Areas
Governance	A central nodal agency and unified national framework
Infrastructure	Coastal biorefineries and processing hubs strengthen waste segregation, cold chain, and R&D infrastructure.
Finance	Funding mechanisms and incentives for coastal communities, startups, and R&D
Innovation	Support for R&D, tech-transfer, scale-up, and collaboration between industries, research institutions and government
Community Engagement and Capacity Building	Training, skill development and capacity building for coastal communities, particularly women and youth

To achieve scale and address the gaps, a unified governance and strategy is required, as frequent policy shifts negatively impact industrial participation and investments. In this context, strengthening the key policy pillars (Table 3), such as governance, infrastructure, finance, innovation, and community inclusion, are essential for advancing the valorisation of marine biomass waste.

Governance

At present, marine biomass waste management is spread across multiple ministries, such as the Ministry of Environment, Forest and Climate Change (MoEFCC) and supported by the Ministry of Ports, Shipping and Waterways (MoPSW), the Ministry of Commerce and Industry, Department of Biotechnology (DBT) and the Department for Promotion of Industry and Internal Trade (DPIIT). This division of responsibility, with each entity having its own siloed jurisdiction, leads to the duplication of efforts, confusion, and delays in the large-scale implementation of projects.

Figure 3: India's Blue Circular Economy: A Proposed Central Framework

Source: Author’s own

An integrated national policy (Figure 3) led by a single nodal government agency would unify these efforts under a coherent framework for marine biomass valorisation, waste regulation, and sustainability. This central agency should have a governing board that includes permanent representatives from key ministries such as the MoEFCC, the MoPSW, the Ministry of Commerce and Industry, DBT, and the DPIIT, while ensuring representation from all coastal areas. This structure will help minimise duplication, bureaucratic delays, and streamline the policy-making and implementation process. 

Infrastructure

The policy should outline a roadmap for marine waste-to-wealth and support the development of bio-based products from ocean waste, as well as the establishment of marine biorefineries, scalable and sustainable processing facilities, and increased investments in research and innovation. The funding mechanisms should adopt a multi-criteria model for decision-making rather than focusing solely on the final product.^[88] They must account for the financial savings resulting from the benefits of the circular economy, including resource efficiency, waste management, environmental benefits (reduced carbon footprint, GHG emissions, and pollution), and socio-economic benefits, including the creation of new economic avenues and job opportunities. The government must expand its existing ‘Waste to Wealth’ mission to include dedicated policies for the valorisation of marine waste.^[89] Furthermore, integrating waste valorisation with other existing schemes, such as Swachh Bharat 2.0, the Bio-Energy Programme, and the Atal Innovation Mission, can create a coordinated framework instead of treating it as a standalone mission.

The nodal agency should standardise policies for marine waste collection and segregation, which is essential due to the heterogeneous nature of the waste.^[90] Such standardisation must have the technical oversight by the Ministry of Fisheries, Animal Husbandry and Dairy (MoFAHD) and MoEFCC, with active support from the DBT and MoPSW. Regulatory protocols are essential for ensuring the quality and uniformity of waste composition, thereby facilitating efficient processing. Dedicated training programmes for coastal communities will ensure the proper handling and segregation of marine biomass waste.

The agency should support and promote the concept of an integrated marine biorefinery, which combines multiple processing pathways to convert marine biomass into high-value products while achieving zero waste, to help minimise waste and maximise economic benefits.^[91] Instead of focusing on a single product, co-product extraction can significantly increase the financial viability and profitability.^[92]

Marine biomass represents an untapped source for the development of high-value products.^[93] This includes byproducts from fisheries and aquaculture, beach wrack, seaweed, and other marine byproducts that can be used for the extraction of biopolymers, nutrients, and bioproducts. These are useful in the nutraceutical, pharmaceutical, livestock/pet food, and biofuel industries. Seaweed, with its potential for conversion into biofuels, bioplastics, biofertilisers, and biodegradable polymers, is abundantly available along the coasts of Tamil Nadu, Andaman, and Gujarat.^[94] Seaweed cultivation should adhere to carefully crafted policy guidelines and regulatory frameworks, as excessive cultivation could disrupt the marine food web due to disproportionate growth, competition with native marine species for light and nutrients, and the risk of invasive species and associated diseases.^[95]

Processing beach wrack into biochar and biofertilisers aligns with the national mission to promote sustainable agriculture by reducing the use of chemical fertilisers.^[96] For instance, oyster shells and mussels can replace calcium carbonate, thereby reducing India’s plastic pollution, which in turn brings down the import burden. India’s plastic pollution can be seen as a circular loop, feeding back into the ocean. The rivers carry discarded plastic waste from land into the sea, where it breaks down into microplastics that enter and harm the food chain.^[97]

In a circular blue economy approach, waste materials such as seaweed polymers, shells, and algae can be converted into biodegradable plastics, thereby encouraging a closed-loop system.^[98] They cut down the non-degradable plastic waste discarded into the ocean and create sustainable solutions. DBT and MoFAHD should help support the setting up of multi-product biorefineries for processing marine biomass waste. Scale-up studies and industrial-scale adaptation of these models should be encouraged. Circular economy solutions should be promoted through the development of biodegradable products and the implementation of the waste-to-wealth concept.

While marine biomass offers a massive opportunity for valorisation, tackling plastic, fishing, and ghost gear, which are often mixed with marine biomass waste, is essential to leverage its full potential. Recent research suggests that the use of biodegradable materials, such as biopolymers, for making shipping, fishing, and ghost gear could be a potential solution to marine pollution.^[99] Utilising digital tracking systems, such as those employed by the Global Ghost Gear Initiative, can help monitor the loss of this equipment.^[100] Combining technological innovations with policy measures, such as Extended Producer Responsibility (EPR) and financial incentives for the retrieval of ghost gear, along with increased community engagement, would enable India to make meaningful progress towards achieving the goals of marine biomass waste valorisation.

Infrastructure development, led by the nodal agency, should ensure the establishment of waste valorisation clusters and coastal community-led waste collection and sorting systems with active support by MoPSW.^[101] The policy should focus on capacity-building and training programmes led by MoFAHD for coastal communities, aimed at the proper handling and segregation of the waste. It should also focus on establishing coastal biorefinery plants, processing hubs along the coastline, and shared laboratory facilities and pilot plants, supported by the DBT and the Ministry of Micro, Small and Medium Enterprises. The creation of incubators for startups focusing on marine biomass waste valorisation could help reduce entry barriers for new startups.

Finance

The proposed nodal agency should design policy reforms that focus on financial incentives, such as recycling mandates, tax incentives, or a reduction in Goods and Services Tax for valorised and recycled products, creating new markets. The Ministry of Finance must support such an agency with adequate budgetary allocations. Low-interest loans and grants for projects and startups focusing on marine biomass waste valorisation will support more research and innovation in the field. The implementation of national models similar to market-based innovation platforms, such as EcoEx, could be designed to monetise ocean biomass waste streams and register local communities for waste collection and segregation, earning financial rewards or tradable credits.^[102] Such policies should incentivise marine biomass waste collection, segregation, and processing, and integrate the model into broader frameworks, such as ESG reporting. This approach will facilitate more public-private-community partnerships and bring together startups, researchers, environmentalists, and local communities.

Innovation

The nodal agency should design policies to ensure effective collaborations among academia, industry, startups, and government for the large-scale adoption of marine biomass waste valorisation technologies. In partnership with the Ministry of Science and Technology, DBT, the Ministry of Commerce and Industry, and the DPIIT, the agency should provide grants and financial support for research and innovation for waste valorisation. Allocating funding for Techno-Economic Analysis and the Life Cycle Assessment of novel technologies and processes could help identify ways to reduce cost, implement greener processes, and ensure long-term viability before making massive upfront investments to set up plants.^[103]

This nodal agency should foster collaborations between academia, industry, startups, and government to enable them to work together and provide feasible solutions. It must also promote lab-to-pilot scale and pilot-to-commercial scale studies to ensure long-term viability. Policy interventions could allow for a more realistic timeline of up to 24 months, as opposed to the current six-12 months for these studies, ensuring comprehensive analysis, optimisation, and industrial adoption of the technologies.

Community Engagement and Capacity Building

Engagement and capacity building with local coastal and fisher communities should be central to the nodal agency’s strategy to ensure the success of marine biomass waste valorisation initiatives. The agency should bring the Ministry of Rural Development and the MoFAHD together to provide financial incentives for communities participating in waste collection and segregation. Awareness campaigns on sustainability and the economic potential of marine biomass waste are essential among coastal communities. Local micro-enterprises should be encouraged by providing funding and infrastructure support. Special focus should be given to the involvement of women and children through awareness campaigns, skill development initiatives, educational programmes, and financial incentives for students and women-led micro-enterprises, with a focus on valorising marine biomass waste. Global models such as the Pacific Community’s Women in Fisheries Programme, which offers funding, training, and market access to youth and women-led blue enterprises, can be taken as examples^[104]. A dedicated Blue Gender-Inclusion Enterprise Fund could support women and transgender-led blue economy startups and enterprises focusing on marine biomass waste valorisation to strengthen gender inclusion.

Conclusion

India’s vast coastline and abundant marine biomass waste offer a unique opportunity for advancing sustainable growth by transforming waste from a burden into valuable resources. Integrating a circular economy model into the blue economy framework will enable the sustainable utilisation of marine resources, resulting in multifaceted positive outcomes, including marine biomass waste management, environmental benefits, value generation, financial benefits, employment opportunities, and social development, particularly in empowering women.

Marine biomass waste, including fish waste, shell waste, seaweed, and beach wrack, can be utilised for the extraction and production of biomaterials and biochemicals that are functional in the development of nutraceuticals, food, animal feed, pharmaceuticals, biopolymers, bio fertilisers, biodegradable packaging films, biofuels, and other high-value industrial compounds. Seaweed valorisation holds promise for the production of renewable energy, such as biofuels and carbon capture. These initiatives can address environmental and social challenges, such as ocean pollution, and create new livelihood opportunities for coastal communities.

Currently, marine waste management is fragmented across multiple sectors. A central nodal agency with permanent representatives from the MoEFCC, the MoPSW, the Ministry of Commerce and Industry, DBT, and the DPIIT would ensure streamlined policy and decision-making, ensuring that delays and duplication of efforts do not impede progress. The agency will ensure coordination between various ministries and departments for policy-making, waste segregation and collection, promote biorefineries for co-product extraction, allocate funding, develop infrastructure, conduct research and innovation, scale up technology, and engage local coastal communities. Community participation, facilitated through skill development and training programmes, as well as the encouragement of microenterprises, especially for women, is central to this effort.

By employing appropriate valorisation strategies, India can convert marine biomass waste into valuable products rather than becoming an environmental burden. A holistic approach to policy initiatives, focusing on marine biorefineries, a circular economy, improved infrastructure, feedstock segregation, and community engagement, could help India achieve its blue economy targets. Taking these steps can position India as a global leader in sustainable marine biomass waste-based industries and advance a blue economy that is both environmentally sustainable and socially inclusive.
