Grand Challenges is a family of initiatives fostering innovation to solve key global health and development problems. Each initiative is an experiment in the use of challenges to focus innovation on making an impact. Individual challenges address some of the same problems, but from differing perspectives.

Field Testing of Off-grid, Self-sustained, Modular, Electronic Toilet for Slums, with Solar Energy for Indian Weather and Integrated with Mixed Waste Processing Unit, with Water, Energy/Fertilizer Recovery
This project, undertaken in collaboration with the University of South Florida, U.S., aims to develop and demonstrate an innovative sanitation and resource recovery solution for the slum areas in India.
Hygienic Water-Free Toilet
This project aims to redefine the receiving material for human waste from water to granular material, thereby completely bypassing the need for water in this process. The project aims to redesign the conventional toilet to use a bed of granular that will ensure that there is no fecal staining of the system, fecal matter is cut-off from vectors, does not contaminate surface waters and that the user is always presented with a fresh, clean and dry surface.
Use of Viral Agents, Microbial Fuel Cell and Effective Recycling Strategy to Improve the Economics of Human Waste Disposal
This is a proof-of-concept development for using viral agents to target and kill pathogens and odor-producing bacteria in fecal waste and also develop for ways to integrate this into waste treatment systems. The potential of this project is immense as, once thoroughly tested; it will provide a completely natural alternate to managing pathogens in waste water.
Empowered Septic Tank as Decentralized Wastewater Treatment System
Srikanth Mutnuri from BIRAC in India in collaboration with Willy Verstraete from Ghent University in Belgium, will aim to develop a financially affordable and simple-to-operate decentralized wastewater treatment system for a single household as well as for a gated community of 100 people (25 families) that will produce high quality effluent for safe disposal. The waste treatment system relies on electrochemical reactions and the production of chlorine, to manipulate the pH of the wastewater to destroy pathogens and helminthes.
Effect of Environmental Parameters on the Treatment of Human Fecal Waste by Black Soldier Fly Larvae
This project aims at refining a biological-agent based technology to understand the optimal conditions needed for its efficient use in India. It aims to use Black Soldier Fly Larvae (BSFL) to consume the human fecal matter and other bodily wastes. The team will test the optimal environmental conditions, in terms of temperature and humidity, for Black Soldier Fly larvae (BSFL) to reduce the amount of human feces in waste septage.
Eco-Toilet
This project aims to utilize ultrasound to move and settle human waste collected in a specifically designed latrine. This redesigned latrine uses less water and therefore provides a more sustainable solution to collect human waste.
