Human waste fuels Kenyan homes

Environmental activists in Kenya are trying to make their community more energy efficient.

Naivasha is known for its flower farms which earn the government millions of dollars from export. But it is also a sanitation hazard.

There are not enough toilets and no proper waste disposal system.

So, most of the waste here is dumped in the town’s scenic lake. A non-profit organisation called sanitation is trying to change that.

They want to convince people that human waste can be a source of fuel.
