The Bill & Melinda Gates Foundation just announced a couple of new programs to help address sanitation around the world. The first is a $3M grant to 8 universities across the world to redesign a toilet that would not rely on electricity or piped in water, and that would deal with wastes in a more productive way (composting?) with a target cost of 5 cents per day per person. Also $42M in support for different initiatives and projects for waste conversion to energy and other higher-tech applications.
I'm curious where exactly this $42M is being given to, as well as what the universities will come up with! It really is such an important topic, linked to human health, the environment, and soil fertility.
