Here at Cranfield we are developing the Nano Membrane Toilet which will be able to treat human waste on-site without external energy or water. The Cranfield toilet is designed for single-household use (equivalent to 10 people) and will accept urine and faeces as a mixture. The Cranfield toilet is still under development; this is the vision of how it will work: The Cranfield toilet flush uses a unique rotating mechanism to transport the mixture into the Cranfield toilet without using any water whilst simultaneously blocking odour and the user’s view of the waste.
