The next generation toilet?
A CWSI concept known as the Nano Membrane Toilet was recently selected by the Bill & Melinda Gates Foundation as a winner in its ‘Reinvent the Toilet Challenge Round 2’. The Nano Membrane Toilet aims to treat human waste without external energy or water and uses a combination of innovative nano and advanced water treatment technologies and Cranfield University’s specialist design skills. The concept works by reducing the water content of the sludge through membranes that allow extraction of water as a vapour, using a mechanism powered by the user. The resulting sludge moves downwards under gravity and is encapsulated in briquette form, with the potential for reuse in combusting or applying to land as a fertiliser.
Solving water and sanitation problems in Sub Saharan Africa
Water, sanitation and hygiene (WASH) technologies have potential to meet the needs of populations in Sub-Saharan Africa and other developing countries but few have actually been scaled-up and integrated into country development strategies. With support from the European Commission 7th Framework Program and in collaboration with development partners from Europe and Africa, CWSI have developed a range of tools to aid WASH technology assessment and scale-up. The project, known as WASHTech, employed an action research methodology within three participant countries; Burkina Faso, Ghana and Uganda. The tools are now in the public domain and being used via the Rural Water Supply Network.

The CWSI had been on my radar since I became interested in water treatment during my bachelor's studies, and after my master's I knew I wanted to work in WASH. Being part of the NMT-project allows me to do that on a scale of potentially global impact, while working with people doing all sorts of exciting water-related research.Jan Hennings, Current PhD student
