Introduction

In the face of escalating climate change and increasingly volatile agricultural markets, the global food value chain faces significant challenges. Among the many commodities affected, onions—a staple in Indian households and a major export crop—are particularly vulnerable to post-harvest losses. India, the world's second-largest onion producer, accounts for 24.4 million metric tons annually. Yet, a significant portion of this produce goes to waste due to inadequate storage infrastructure.

The impact of these losses extends beyond individual farmers; it disrupts market stability, depresses farmer incomes, and wastes resources. To address these pressing issues, Temperate Technologies has introduced the Controlled-Environment Onion Storage Solution. This innovation not only reduces wastage but also enhances profitability for farmers by enabling them to store onions for longer periods and sell at optimal market prices. Let’s explore this game-changing solution and its transformative potential.

The Problem: Challenges in Onion Storage

Onions, despite being a high-demand cash crop, suffer substantial losses throughout the supply chain. Traditional storage methods, primarily used by smallholder farmers and Farmer Producer Companies (FPCs), have several critical flaws:

1. Unscientific Designs: Storage facilities often lack proper ventilation, exposing onions to extreme weather conditions like heavy rain and direct sunlight. This results in rapid spoilage.
2. High Post-Harvest Losses: Studies reveal that losses in traditional storage systems can range from 35% to over 60%, depending on weather and handling conditions.
3. Rot and Sprouting: Poor stacking systems, combined with inadequate curing methods, lead to accelerated rotting and sprouting of onions.
4. Market Volatility: Farmers without proper storage facilities are forced to sell their produce immediately after harvest, often at lower prices due to market saturation.
5. High Operational Costs: Inefficient manual processes for loading, unloading, and sorting further increase the cost burden on farmers.

These issues highlight the urgent need for a modernized storage solution tailored to address these pain points.

The Solution: Controlled-Environment Onion Storage Structure

Recognizing the challenges faced by farmers, Temperate Technologies developed the Controlled-Environment Onion Storage Solution, a state-of-the-art facility designed to ensure optimal storage conditions. Here’s how this solution addresses the critical gaps in traditional systems:

1. Controlled Atmosphere:
   • It integrates curing and storage functions, maintaining precise control over temperature, humidity, and airflow.
   • This ensures that onions remain fresh and disease-free for up to six months, significantly extending shelf life.
2. Scientific Design:
   • The stacking system is engineered to optimize airflow and minimize rot.
   • Worker-friendly layouts ensure safety and ease of operation.
3. Cost-Effective Implementation:
   
   • Designed for scalability, the 50 MT capacity facility balances affordability and efficiency, making it accessible to FPCs and smallholder farmers.
4. Adaptability:
   
   • While designed primarily for onions, the storage structure can accommodate other perishables, especially garlic, maximizing its utility year-round.

Financial Viability: A Profitable Investment

The financial sustainability of the Controlled-Environment Onion Storage Solution is one of its most compelling features. Here’s why it makes economic sense for farmers and FPCs:

Cost Breakdown

• Capital Investment: The total project cost for a 50 MT facility is approximately INR 18 lakh.
• Subsidy Support: Eligible FPCs can avail subsidies of up to 50% under government schemes like PoCRA, reducing the net investment to around INR 9 lakh.
• Operational Costs: Semi-automated systems and optimized designs minimize daily operational expenses.

Returns on Investment

• Reduced Losses: Losses in Controlled-Environment Onion Storage Solution are as low as 10-15%, compared to 35-60% in traditional systems.
• Higher Market Prices: By storing onions during peak harvest and selling them when prices rise, farmers can achieve significantly higher profit margins.
• Short Payback Period: With subsidies, the discounted payback period is just 1 years, and the Internal Rate of Return (IRR) is > 80%.

Business Model

The structure enables FPCs to adopt flexible business models:

1. Direct Purchase: FPCs procure onions directly from farmers at pre-agreed rates, ensuring stability for both parties.
2. Rental Scheme: Farmers store their onions in the facility for a nominal fee, retaining control over selling decisions.

Empowering Farmers and Promoting Sustainability

The Controlled-Environment Onion Storage Solution goes beyond financial benefits; it contributes to broader social and environmental goals:

1. Economic Empowerment:
   
   • By reducing wastage and enhancing market access, the solution directly contributes to the government’s "Doubling Farmers’ Income" initiative.
   • It promotes rural entrepreneurship by equipping FPCs with advanced technology and training.
2. Food Security:
   
   • By minimizing post-harvest losses, the structure ensures a more stable supply of onions, reducing price volatility for consumers.
3. Environmental Benefits:
   
   • Unlike chemical-based storage methods, the Controlled-Environment Onion Storage Solution uses natural processes, eliminating health and environmental risks.
   • It supports climate resilience by protecting produce from unpredictable weather.
4. Alignment with Sustainable Development Goals (SDGs):
   
   • SDG 2: Ensures food security and promotes sustainable agriculture.
   • SDG 12: Reduces food wastage and improves resource efficiency.
   • SDG 13: Strengthens resilience against climate-related risks.

Market Potential and Scalability

India’s onion production has consistently exceeded domestic consumption, creating opportunities for export and storage-based price stabilization. However, inadequate infrastructure has hindered market optimization. The Controlled-Environment Onion Storage Solution addresses this gap by enabling:

1. Forward Linkages:
   
   • Direct APMC Sales: FPCs can sell stored onions at peak market prices, maximizing revenue.
   • Institutional Contracts: Partnering with large buyers like schools, restaurants, and food processors ensures steady demand and predictable income.
2. Backward Linkages:
   
   • FPC Membership: By aggregating produce from member farmers, FPCs can negotiate better prices and streamline operations.
   • Standardized Practices: Encouraging the use of uniform seed varieties enhances storability and quality.
3. Export Potential:
   
   • With improved quality and extended shelf life, Indian onions can gain a competitive edge in international markets.

Conclusion: A Blueprint for the Future

The Controlled-Environment Onion Storage Solution represents a transformative solution to one of agriculture’s most persistent challenges. By combining innovative technology, financial viability, and sustainability, it addresses the needs of farmers, consumers, and policymakers alike.

For entrepreneurs, agribusinesses, and policymakers looking to revolutionize post-harvest management, this model provides a scalable and impactful framework. As we strive toward a future of resilient and inclusive agriculture, solutions like the Controlled-Environment Onion Storage Solution will play a pivotal role in shaping the narrative.
