Marking World Toilet Day in London and Barcelona

We were delighted to receive two invitations to talk about the toilet at World Toilet Day events.

Firstly, WSUP hosted a showcase of sanitation research as part of their My Toilet  exhibition.   Jake Larsson gave a short talk about the Nano Membrane Toilet, alongside other Cranfield researchers:

• Elise Cartmell presented the Transforming Waste consortium's work on anaerobic digestion  and nutrient recovery from pit latrine sludge in Zambia.
• Ben Martin introduced the trials we are doing on different technologies to treate the Clean Team waste in Ghana.
• Ruben Sakrabani talked about our research on the efficacy of Loowatt's human waste derived fertilizer in Madagascar.
• Peter Cruddas explained what waste streams would be appropriate for co-pyrolysis of pit latrine sludge.

Cranfield's technical research was balance by presentations from WSUP on their research into topics such as health impacts and mobilising municipality finance for sanitation.   Overall it was a fantastic event that really demonstrated the breadth and importance of sanitation research, and we were honoured that the Nano Membrane Toilet was a part of it.

 Secondly, Ross Tierney was invited out to join a panel of experts at the World Toilet Day and Improving Sanitation event hosted at the Roca Gallery Barcelona. The other speakers alongside Ross included Xavier Torras, Corporate Brand and Communication Director at Roca; Jordi Corral, Innovation Lab Project Manager from Roca; Mark Frantz, Fundraising Manager from Unicef; Martin Azua a designer and architect interested with particular interest in toilets and bathrooms.  The topic of conversation on the night revolved around providing access to sanitary solutions for the most vulnerable people with particular focus on equality and dignity for women and children, a theme we are certainly exploring with the Nano Membrane Toilet.

The judges said, "This is a strong project that has the potential to provide sanitation to people who do not currently have a toilet - 2 billion people around the world."   Our Vice Chancellor, Professor Sir Peter Gregson added, "The Nano Membrane Toilet project exemplifies the innovative, transformational and multidisciplinary research for which Cranfield is renowned. Winning this Award enhances awareness of Cranfield’s international research capabilities in water and sanitation, and provides much-deserved recognition for the hard work and dedication of all the project team."

Kickstarting collaboration

The key to success in the next phase of the project is collaboration with other grantees who have already solved some of the tricky problems and who have invaluable expertise.   Last week we kick-started these collaborations with a series of visits and discussions.

Firstly Athanasios traveled to visit RTI International in San Francisco.   He's arranged for one of their gasifiers to be shipped to us to test and incorporate into our toilet.   Watch this space for its arrival!

Secondly,  Jeremiah Deal and Heather Deal from Three Bird Swan came to help is with some of our components like the pelletiser which will produce dry pellets form the dewatered sludge to go into the gasifier.   They also gave us some ideas on our whole system integration.

Thirdly, Chris Buckley and Tina Velkushanova from the University of Kwa Zulu Natal came to share their experience of using an Archimedes screws to transport faecal sludge, as well as make some suggestions of how to make sure the flush provides a total odour barrier.

 

Peter, Chris and Tina examine the works-like prototype which will be used for the initial screw testing.

Chris, Ross and Tina consider how the bowl design will affect smearing.

Finally, Colleen Archer from UKZN came to give a talk about how the Ascaris egg can be used as a marker organism to detect if faeces is safe for reuse.   She also shared some fascinating stories about sanitation in her home town of Durban.

The Nano Membrane Toilet receives further funding

We are delighted to announce that the Nano Membrane Toilet has received further funding from the Bill and Melinda Gates Foundation to continue the development of the toilet.   This next phase will take us to January 2016 when we will have a prototype ready for field testing.   We're really excited to be starting work again after a 6 month break.

We will be continuing to work on some of the components from phase one, particularly the initial collection chamber, the membrane, the flush and the screw, the latter in collaboration with UKZN.   The biggest change is that rather than coating the dried solids, we're now looking to combust them in the toilet using a gasifier - we'll be working with RTI who are already testing their gasifier in India.   This changes the energy balance of the toilet, for example we can now consider recovering the water using a heat exchanger instead of the beads, and we won't have to use the bicycle power generator or hand crank to power the membrane processes.

These new components will require changes to the overall toilet design, and also an intelligent control system which we'll work on with Three Bird Swan.   We'll also continue to collect the perceptions of our target users, through interviews with the customers of Clean Team in Ghana.

Keep following the blog for updates and get in touch with any questions.

Reinvent the Toilet Phase 1. Design Team progress photos.

Created with flickr slideshow.

As we have now reached the end of Phase one the Design Team wanted to show some snaps of the project as it's developed over the course of the year.

This album shows primary research in Ghana, early idea generation to prevent smell in the form of a waterless flush, the workshop, aesthetic design development, CAD work, building the Aesthetic prototype and the culmination of the first phase of the project; the Reinvent the Toilet fair in Delhi, India.

The Design Team consisting of Jake Larsson, Ross Tierney and Dr. Leon Williams are looking forward to getting back to the drawing board and continuing with the the challenging and fascinating project and also potential future collaborations and opportunities.

Partnerships

We’d like to take an opportunity to acknowledge and thank the partners we’ve worked with so far on the Nano Membrane Toilet.   They’ve all done exceptional work.  

Model Products worked built the technical 'works-like' rig that was on display at the Reinvent the Toilet Fair in Delhi and the Natural History Museum. The rig brought together the individual components to create a whole system that will allow for future testing and development. The rig was built to a very high standard and attention to detail was evident with great consideration given to usability during testing.

NextShoot produced the video that explained the toilet system and the impact to the target market in a succinct and engaging manner. Their enthusiasm, skill and experience combined to convey a complex system very effectively in a short amount of time.

Spectrum Gas Systems fabricated the membrane and condensation test rigs, which were instrumental in benchmarking the performance of individual components. The data generated here informed the design of both the "works-like" rig, and the "looks like" prototype.

BMS were involved in early idea generation and concept development on the odour barrier and the fabrication of the demonstration prototypes. Their diverse background helped during the creative process and with many years practical experience, they were able to produce robust test rigs that clearly explained the ideas.

Artem produced the Aesthetic prototype that allowed people to interact with the toilet and understand the aspirations of the Cranfield team. The ‘looks-like’ prototype gave an impression of a high quality product and fulfilled the aspirational image that the team wanted to convey.
