Novel and Eco-friendly lightweight Thermal Insulating Ceramics from Thermal Power Plant Waste

Student of Institute of Chemical Technology, Mumbai, Yogesh D. Urunkar and Chandrakant S. Bhogle won the award for a Novel and Eco-friendly lightweight Thermal Insulating Ceramics from Thermal Power Plant Waste. They carried their project work under the guidance of Prof. Aniruddha B. Pandit and Prof. J.B. Joshi.

India alone produces 169 MT of the fly ash per annum from 155 thermal power stations, out of which 50% were unutilized and dumped into the land. This may cause catastrophic effects on the environment. Therefore, it is very much essential to utilize this fly ash in a novel, eco-friendly and economical way. This innovation targets the problems caused by fly ash due to its non-utilization and provides a sustainable and practical alternative to the existing ceramic material. The developed fly ash ceramic material has unique properties such as it is an ultra-thermal insulating and very lightweight. The density of the developed material is 0.6- 0.8 g/cc so that it can also float on the water.

Its thermal conductivity varies from 0.2-0.5 W/m.k which is four to ten times better compared to the existing ceramic materials. Apart from this, it can be moulded into any size and shape and provides good mechanical strength. The raw material, which is fly ash, abundantly available at zero cost. All these miraculous combinations of desired properties makes it very attractive alternatives to the existing ceramics. Therefore, developed ceramic can be used in the construction & building as roof tile, wall tile, roofing sheets, industrial thermal insulation, decorative pottery items, variety of other applications.

The Hon’ble Vice President of India, Shri M. Venkaiah Naidu awarded the Gandhian Young Technological Innovation (GYTI) Award to Yogesh D. Urunkar and Chandrakant S. Bhogle Institute of Chemical Technology, Mumbai at the GYTI 2019 Awards function held at Vigyan Bhawan, New Delhi on July 06, 2019.
