- Example: A cold storage facility for fruits and vegetables in California helps extend the shelf life of produce, allowing it to be distributed across the country and internationally without spoilage.
1.2 Reduction of Wastage:
- Overview: Proper cold storage prevents the loss of perishable goods due to spoilage, thereby reducing food waste and associated economic losses.
- Economic Impact: Reducing wastage helps lower costs for producers and retailers, stabilizes market prices, and contributes to a more efficient supply chain.
- Example: In India, cold storage facilities for potatoes help manage the seasonal glut and shortages by storing surplus produce, reducing waste and price volatility.
1.3 Enhanced Supply Chain Efficiency:
- Overview: Cold storage facilities enable a smooth and efficient supply chain by ensuring that perishable goods are stored and transported under optimal conditions.
- Economic Impact: Improved supply chain efficiency reduces transportation costs, minimizes disruptions, and ensures timely delivery of goods, benefiting both consumers and businesses.
- Example: The use of cold storage in the pharmaceutical industry ensures that vaccines and medicines are stored at precise temperatures, maintaining their efficacy and supporting public health.
1.4 Market Expansion and Access:
- Overview: Cold storage facilities enable the export of perishable goods to distant markets by extending their shelf life and maintaining quality during transportation.
- Economic Impact: This facilitates market expansion for producers and exporters, increases trade opportunities, and contributes to economic growth.
- Example: The cold storage infrastructure in New Zealand supports the export of dairy products to international markets, contributing significantly to the country’s economy.
2. Types of Cold Storage Facilities
2.1 Refrigerated Warehouses:
- Overview: These facilities are designed to store perishable goods at temperatures above freezing but still within a controlled range to maintain quality.
- Economic Impact: Refrigerated warehouses support the storage and distribution of a wide range of products, including fruits, vegetables, and dairy items.
- Example: The Cargill refrigerated warehouse in the United States stores meat products at controlled temperatures, ensuring their quality and safety for consumers.
2.2 Freezer Warehouses:
