 What we're doing here is providing clean toilets and transforming waste actually into a fuel that can be used to replace firewood in the camp. Their waste is being collected every three days. We're treating it here at this localized treatment site, actually using solar concentrators that just use the sun's energy to kill off all the pathogens. We're then combining that with some other charcoal dust and other waste and creating an alternative burning fuel to replace the burning needs here in Kakama. The charcoal is actually fantastic. It actually has less carbon monoxide output than normal charcoal. It has less particulate emissions. It actually burns longer. And since you're using two waste products, you're actually helping with deforestation. These drums here are full of human feces and what we're doing with solar treatment is rendering the feces safe to be reused through concentrating the sun's energy and getting the feces to high temperatures that inactivates all the pathogens. Here's our mixture of treated feces with charcoal dust and what we do with this mixture is we press it with our press to make charcoal briquettes. The waste is compacted down. It's nice and squeezed tight. You get a compression that actually produces a handful of briquettes like this.
