The concept of a circular economy (CE) is gaining policy attention in India as a sustainable alternative to the traditional linear model of “take–make–dispose.” In the dairy sector, this approach is emerging as a transformative model that links farmer income enhancement, environmental sustainability, and rural industrialisation. Recent initiatives such as Banas Dairy’s bio-CNG and organic fertiliser plant in Gujarat highlight how circular principles can significantly improve livelihoods, with projections suggesting up to a 20% rise in farmers’ income over the next five years.

Understanding the Circular Economy

A circular economy is designed to minimise waste and maximise resource efficiency by keeping materials in productive use for as long as possible. It emphasisesreuse, recycling, refurbishing, and regeneration of natural systems, in contrast to the linear system that depletes resources and generates waste. In agriculture and dairy, CE integrates biological cycles, ensuring that by-products return to the soil or energy system rather than becoming pollutants.

India has already incorporated CE principles through initiatives like the Vehicle Scrappage Policy, Swachh Bharat Mission, Mission LiFE, and promotion of waste-to-wealth projects. The dairy sector now represents a critical frontier for applying this framework at scale.

Circular Model in the Dairy Sector

India is the world’s largest milk producer, yet the sector has historically focused only on milk procurement and processing. The circular model broadens this vision to include value recovery from dairy waste and diversification of products.

A key example is the conversion of cattle dung into biogas (bio-CNG) and organic fertiliser. This creates multiple benefits:

• Additional income streams for farmers
• Reduced dependence on chemical fertilisers
• Lower reliance on fossil fuels
• Improved soil health and energy security

Beyond waste-to-energy, CE encourages diversification into value-added dairy products such as milk powder, specialty cheeses, and nutraceuticals. This aligns with global demand trends and can boost exports, MSME participation, and rural supply chains.

Even by-products like hides from naturally deceased cattle can be ethically utilised within cooperative frameworks, preventing waste and generating supplementary income.

Banas Dairy as a Model of Circular Integration

Banas Dairy in Gujarat, one of Asia’s largest dairy cooperatives, exemplifies this integrated approach. With a large-scale bio-CNG plant, fertiliser production units, and expanded milk-processing infrastructure, it demonstrates how cooperatives can function as multi-product, zero-waste ecosystems. Its success is being positioned as a model for replication across India under the vision of White Revolution 2.0.

Role of Cooperatives and Women

The cooperative model is central to CE adoption in dairy. Institutional support through the Ministry of Cooperation, affordable credit, and technology access is crucial. Importantly, women dairy farmers play a pivotal role, with direct income transfers enhancing financial inclusion and women-led development.

Challenges

Despite its promise, scaling the circular dairy economy faces challenges:

• High initial capital costs for biogas and processing plants
• Technological gaps in small dairies
• Need for training and skill development
• Inadequate cold chain and logistics infrastructure
• Regulatory oversight for ethical by-product utilisation

Way Forward

To realise its potential, India must provide targeted financial support (NABARD, cooperative banks), promote skill training, strengthen export linkages via APEDA, and expand cold chain networks through PPPs. Policy convergence with Atmanirbhar Bharat, Doubling Farmers’ Income, and climate commitments will further accelerate adoption.

Conclusion

The circular economy in the dairy sector represents a structural shift from subsistence to sustainability. By converting waste into wealth, promoting value addition, and strengthening cooperatives, India can simultaneously achieve rural prosperity, environmental resilience, and global competitiveness in the dairy economy.
