Billionaire philanthropist Bill Gates wants the world to sit up to a serious issue that affects nearly half its population: sanitation.

He’s investing hundreds of millions into finding solutions to the problem, and has done so for the past seven years. He said providing sanitation is a step toward reducing poverty.

He hopes to develop technology that takes in human waste, kill dangerous pathogens and converts the resulting materials into products with potential commercial value like clean water, electricity and fertiliser.
