IS 17693 : 2022 Non-electric Cooling Cabinet Made of Clay

In this era, where the world is dominated by technology and advancement, there are people in our country who still bank on traditional cooling. Since ancient times, our ancestors relied on pots made of clay to, store water and food, cook food, etc. Clay pots have been an integral part of Indian kitchens until factory-made products of variety of materials invaded the market.

Refrigeration is a food storage technique that prevents bacterial growth whereby increasing its shelf life and making it fit for consumption. The majority of India’s population falls into the below poverty line category and appliance like household refrigerator may be unaffordable to them.

Shri Mansukh Bhai Prajapati from Gujarat is the grassroot innovator behind the refrigerator made using clay, popularly called ‘Mitticool Refrigerator’, an eco-friendly technology. It is a natural refrigerator made primarily from clay to store vegetables, fruits, milk, and also for cooling water. It provides natural coolness to foodstuffs stored in it without requiring any electricity. Fruits, vegetables, and milk can be stored reasonably fresh without deteriorating their quality.

‘Mitticool Refrigerator’ was exhibited at the 4th batch of Innovations Scholars In-residence Programme held at Rashtrapati Bhawan (2017) in partnership with the National Innovation Foundation (NIF) that scouts, supports, and spawns grassroot innovations developed by individuals and local communities in any technological field, helping in product and professional development without any help from the formal sector.

Taking cognizance of this innovative technology, the Bureau of Indian Standards (BIS), the National Standards Body of India, has developed an Indian Standard, IS 17693 : 2022 ‘Non-electric cooling cabinet made of clay’. This standard specifies the construction and performance requirements of a cooling cabinet made out of clay, which operates on the principle of evaporative cooling. These cabinets may be used to store perishable foodstuff without the need of electricity.

The impact of this product is boundless. To name a few, it is playing an influential role in reviving the pottery culture, tradition, and heritage; connecting people back to roots in better healthier ways; promoting sustainable consumption; economically empowering the indigent community; working towards green and cool earth, economic development and employment generation; and finally contributing towards rural women upliftment and making them financially independent.

This standard helps in the endeavour of BIS to fulfill 6 of out 17 United Nations Sustainable Development Goals (SDGs), namely 1 (No poverty), 2 (Zero hunger), 5 (Gender equality), 7 (Affordable and clean energy), 9 (Industry, innovation, and infrastructure), and 12 (Responsible consumption and production).
