Prof. Prakash Joshi conceptualized and designed the ‘Bio-toilet’, which is manufactured in FRP therefore keeping it rust free. This Bio-toilet comes with a capacity of 200 litres which can serve about 15 people, whereas other designs which are available with a capacity of 300 litres but they serve only 5 people. This Bio-toilet can be useful in Village Schools, Remote Areas, Fares, and Construction Sites.
