The iThrone that does not consume water or energy

What is the problem being addressed?

Globally, 2.6Bn people lack access to safe, dignified sanitation. Government under-investment into infrastructure, increasing urbanization and crisis-related displacement have resulted in large populations lacking access to safe, proper sanitation. Providing non-sewered communities scalable improved sanitation will incur huge economic costs (for piping, collections, treatment) and unsustainable stresses on local water resources. In non-sewered communities, people must resort to unsafe sanitation options like open defecation and shared pit latrines.

The innovative solution:

Image: change:WATER,

change:WATER Labs has developed a disruptive evaporative toilet to clean up off-grid and non-sewered communities by shrinking daily sewage volumes 85-99% onsite—its portable, low-cost and stand-alone toilets leverage super-water-absorbent polymers to passively vaporize liquid sewage, thus enabling complete sanitary containment, waterless and off-grid operability, and 10x reduced collections logistics.

No water.

No power.

No plumbing.

Stakeholders involved & next steps

This technology is highly impactful for underdeveloped societies. 40% of the world lacks access to safe sanitation, and this impacts every aspect of their lives and their future prospects. Poor sanitation traps them in poverty and hopelessness. The lack of a dignified toilet in fact perpetuates poverty and vulnerability.

Main responsibles to implement this technology should be ONGs and private households (if economic resources are available).


One thought on “The iThrone that does not consume water or energy

  1. Thanks for sharing, Marina! The Change: Water Labs toilet looks like a great improvement on some other small scale sanitation solutions like Peepoo ( and WonderLoo ( From what I’m seeing, it looks like the Change: Water toilet also pretty successfully dries out solid waste in addition to vaporizing the liquid waste. I also read that the initial rollout will be targeted at refugee camps where it sounds like these could make a significant positive impact in such cramped quarters (especially as climate change continues to accelerate global refugee crises). I’m curious about capacity and lifecycle, but it looks like those stats may still be under consideration as the product is developed. Thanks again for the cool find!
