iDE proposes using hydrated lime, an abundant, cheap product, to kill pathogens present in fecal sludge. Latrines are transformed into incubators for valuable agricultural additives, empowering rural Cambodians to take charge of their sanitation.

Since 2006, SOIL has building low-cost ecological toilets in Haiti that provide sanitation access to thousands of people and transform the collected wastes into compost critical for agriculture and reforestation. With the support of Grand Challenges Canada and in partnership with Konbit Sante, SOIL will begin installing private household toilets in northern Haiti to test a revolutionary new social business model for providing household sanitation in urban slums.

This simple, innovative device from India is a wheeled water container that enables the collection and transport of 3 to 5 times as much water as usual per trip, as well as hygienic storage, saving valuable time for productive activities and improving health. By facilitating easier access to water, the WaterWheel reduces the burden of water collection, saves valuable time, and improves health. In the process, it enables women and children to engage in more productive activities, such as school and work.

Hip dysplasia is one of the most frequently observed congenital anomalies in newborns, diagnosed at a rate of 2 percent in Latin America. The incidence is likely higher, given that diagnostics are limited in remote and marginalized communities. Without early treatment, it can develop into a lifelong physical disability. People in rural areas of Latin America who are offered a solution (typically in the form of a harness), do not receive proper education on how to use it properly, which often leads to abandoned or incorrect application, leading to non-recovery or further injury.

A $112,000 CAD grant to the University of Victoria in British Columbia will exploit the potential of 3D printing, producing fully functional artificial hand prostheses for amputees in Guatemala for just $200 each, including material and fabrication costs. The project is based on a prosthesis design developed 15 years ago by innovator Nikolai Dechev, which recently became financially viable with the advent of high-quality, inexpensive 3D printers.

Building on extensive research and development led by Dr. Matt Ratto at the University of Toronto, the cbm Canada project uses a 3D printer to make a precision-fitted plastic socket to connect a child's residual limb and a standard artificial leg provided by aid agencies. Step one requires a precise digital image of a child's limb: early efforts involved a $200 Xbox scanner accessory used in computer gaming, which follows a player's physical movements to put him or her in the action.
