Welcome to the waterless toilets turning human waste into energy and fertiliser

You might have heard of flying toilets. I’m not talking about the well-equipped loos available to us as we soar 39,000 feet into the sky, complete with soft loo roll, airline-branded soap and hand dryers. No, flying toilets are the outcome of people forced to go to the loo in a bag before throwing it into the streets because no better option exists.

According to the UN, 2.5 billion people in the developing world lack what many of us take for granted – access to a toilet. As a result, human faeces ends up on the roadside, in drinking water and eventually in people’s stomachs.

In this recent Guardian article, I explore waterless toilet projects designing innovative ways to deal with human ‘waste’ that enable users to convert poo to profit by turning faeces into useful products, such as organic fertiliser and energy. Circular economy thinking at its best!

Sound a little out there? Have a read and let me know what you think in the comment section at the bottom of the Guardian article… Enjoy!
