Dry toilets for all, forever?

This post was developed as a submission for The Conversation. I have to rework it because “the article covers a huge amount of ground, and that there isn’t immediately a ‘golden thread’ that can be easily identified.” I like it, so it’s going to live here in its current form 🙂

When the probability of Day Zero was first announced in January 2018, the realisation that the extreme drought in Cape Town may affect the functioning of the sewer systems became apparent to everyday people. Through my work in [resource recovery from wastewaters](http://www.futurewater.uct.ac.za/FW-WWBR) and particularly how [sanitation can contribute to the circular economy](http://www.toiletboard.org/media/17-Sanitation_in_the_Circular_Economy.pdf) I have been thinking about the benefits of dry sanitation. I am intrigued by the potential of biological means to recover value from diffuse pollution. But could they ever be introduced at large scale?

Experting in times of crisis: Ethics of care.

This piece brings together concerns that I have from observing responses to the Cape Town water crisis. It was developed as a talk (slides here) which I never got to give, so I would appreciate input to guide me to develop this further.

  2. experting 101: ethics of care
  3. expert #fail: how not to expert
  4. advanced experting: how to jouissance
  5. in closing

Jouissance toilet 2.0 – the foam flush

Why? We’re in drought, so we don’t have water to flush toilets. The nutrients in shit should be re-used, and that is difficult when we dilute it with loads of water and mix it with god knows what else to be shipped off somewhere to be so-called ‘treated’. Also, flushing toilets mean we are flushing nutrients into receiving water bodies (even with excellent wastewater treatment, we’re still not doing well enough). So flushing is just a stupid idea. More about this in a presentation (pdf, 5MB) I recently gave. Continue reading “Jouissance toilet 2.0 – the foam flush”
