The compounds that are rejected by the membrane will flow back into the main holding chamber. The water will be clean enough to use in the house. No liquids are removed by the technicians.

I would say that all of my suggestions for using the ashes would be feasible, especially handwashing ... and this would make your sanitation system all the more complete. If the users want to do something big with the ashes, they can store it up and ask their neighbors to give them more ashes. The last thing we should do is to tell the users to put a resource in the garbage.

What will happen to the liquids that get taken out of the toilets by the technicians?

I still do not understand where the nanomembrane is?

Prince and Orchha - We're still in the development stage but I hope we'd be able to brign it to Kenya, Uganda and India in the future.

Chris -
Thanks for your suggestions. At the moment we're focussed on getting the combustion working effectively, rather than the reuse of the ash. The amount generated will just be a few grammes a day in each household - which of your suggestions would work at that scale?

The liquids will pass over a weir and drain into a small chamber where the membranes are. They will be replaced by the service technician once every 3 months. The used filters will be taken bach to base, regenerated and sent out to another customer.

We're still in an early stage of development, but obviously cost minimisation and reliability are high on our agenda.

Happy to answer any other questions!]]>

Congratulations on these advances and your excellent new video.

I would like to suggest that we avoid putting any product of our toilets into the trash, taking into acoount the general chaos or absence of solid waste management in most parts of the world.

The ashes from the combustion of the feces could be productively used in a variety of ways, including:
-- Washing hands, dishes, pots, etc.
knowledgepoint.org/upfiles/14153226341780206.docx
-- Making soap,
-- Fertilizing soil, esp. mixed with urine collected separately from the toilet,
news.nationalgeographic.com/news/2009/09...-ash-fertilizer.html
-- Controlling insects, such as ants,
-- Giving them to a cement factory or mixing them into concrete while doing masonry
(Reportedly ashes can replace 20-40% of Portland cement

www.sciencedirect.com/science/article/pii/S2090123214000939
www.motherearthliving.com/mother-earth-l...ageid=1#PageContent1
Research was mostly done with "fly ash" from burning coal, which should not be too
different from fecal ash).
-- Or just burying them in the yard would be simple and innocuous.

What happens to the substances that get filtered out of the water? How often do those filters need to be backwashed, maintained or changed?

How long do you think this toilet can function without anything breaking or needing maintenance?

What is the target, unsubsidized price tag for this toilet?

Please remind us where the nanomembrane is.

Dr Alison Parker, from the Cranfield Water Science Institute, said; "This is a great moment; the new funding from the Bill & Melinda Gates Foundation will support our research teams in water, energy and design to tackle the considerable challenge of turning the laboratory prototype Nano Membrane Toilet into a product for the marketplace."

The Nano Membrane Toilet uses a waterless flush; a unique rotating mechanism that drops the waste into a holding tank whilst simultaneously blocking odour and the user's view of the waste. The solids then settle to the bottom of the tank, while the liquids float on the top. The solids are transported out of the tank by mechanical screw into a combustor where they are burnt and transformed into ash. The heat generated can be converted into electricity which is used to power toilet operations, and any residual energy is used for charging mobile phones or other low voltage items. The liquids pass over a weir in the holding chamber and into the membranes bundle. The unique nanostructure membrane allows clean water to be extracted from the waste which can subsequently be used in the household for washing or watering plants.

The toilet is designed for single-household use (up to ten people) and accepts urine and faeces as a mixture. Developed with the aspirations and needs of the user in mind, it is small and easy to transport to locations where there is no access to a water supply and sewer. In comparison to the public toilets relied on by urban communities around the world, a household toilet offers convenience, dignity and security especially for vulnerable groups like women, the disabled and the elderly.

A new video has also been released highlighting some of the recent innovations and improvements to the toilet.



With World Toilet Day (19th November) helping to raise awareness and inspire action to tackle the global sanitation crisis, Cranfield's toilet is attracting interest from around the world, and was recently showcased at the Toilet Investment Summit in Mumbai, India.]]>

1) As mentionned, the festival was organized by the communist party, so I call them the Comrads ... just a joke so.
2) We do have a couple of farmers accepting our urine in our homeland, in the south of France montpellier, but around Paris we don't have yet a re-use site. So unfortunatly all the urine was then thrown in the sewer.
3) We established a partnership with WC Loc, french leader of toilet renting (40% of the national market). They wanted for a long time shift to dry toilets systems but it was literaly impossible for their staff to deal with wood dust. So they welcomed very warmly our separation system with conveyor for several reasons :

  • The fact there's no emptying before 50 000 uses is ecnomicly very interesting for them
  • No electric or sewer connection is very interesting too
  • Only one person dealing with more than 15 cabins (cleaning / recharge of paper and gel) makes loads of savings
  • Obvioulsy communication on the ecological move


Paris has recently commited to place only ecological toilets in all the events next year, if the intention is proven in Public bidding soon there's good chances that WC Loc will renew it's park with a decent quantity of our systems. That would be a big shift for autonomous toilet market in france, stoping the sterile war between dry toiletes and plastic cabin renters that has lasted far too long.

The goal at ecosec is to democratized ecological sanitation, and we don't beleive this is possible if our solutions are not economicly competitive. We beleive with the reduction of manwork managing the cabins we can compete with other technologies.

Thanks for your interets
Best ,

Just a couple of short questions:
  1. What did you mean by "the comrads"?
  2. What did you do with the urine liquid after treatment, i.e. after the phosphorus has been removed from the liquid. It is still high in nitrogen, so did you treat it further or just let it go to the sewer?
  3. How was this demonstration project funded?

We're very happy to share with you the first Struvite reactor we constructed this summer dedicated to the Festivals.
This reactor is fully automized, can remove phosphorus from urine at a rate of 200 l/urine per hour.
We inaugurated it 2 weeks ago at the "Fête de l'huma", 600 000 people in 3 days in Paris organised by the communist party.
Inspired from a similar kind of event made in Amsterdam, see here:


, the comrads, after being sensibilized on the phosphorus end, the nitrate cycle and the benefits of dry toilets systems, were given a little bag of struvite with the inscription "UriBoost, when urine becomes fertilizer"
We "treated" about 2 m3 of urine collecting about 2 kg struvite over the 3 days. People were super pleased, this was all great fun to be honnest. Paris townhall is interested in re-using it when ever they can.
Sorry the comunicatiuon is all in French ... we're working on it.





Our design was based on the previous work on the subject of Bastian Etter, special thanks to him.

Happy to discuss about if you have question.

Best,

Ben, from Ecosec]]>

Title of grant: South African Sanitation Technology Demonstration Programme (SASTEP) – Reinvented Toilet Technology Demonstration and Roadmap to Commercialization

Name of lead organization: Water research commission (WRC); Department of Science and Technology (South Africa) (WRC is the lead organization in this case although our official designation in the project is ‘implementing agent’, and the project is a partnership between WRC, DST and BMGF)

  • Primary contact at lead organization: Jay Bhagwan / Stuart Woolley
  • Grantee location: Pretoria, South Africa
  • Developing country where the research is being tested: South Africa
  • Start and end date: 25 Nov 2014 to 30 Nov 2018
  • Grant type: Other
  • Grant size in USD: From the Bill & Melinda Gates Foundation: 1 million USD (as per grant database: www.gatesfoundation.org/How-We-Work/Quic...s/2014/11/OPP1116992) plus funding by the South African Department of Science and Technology (DST): The DST has committed ZAR 30 million (~US$ 3.0 million) over two years to fund the implementation and field-testing of innovative sanitation technologies and approaches in South Africa.

Goals:

(i) To test the latest in cutting-edge non-sewered sanitation technologies that eliminate faecal sludges and promote resource efficiency; ii) Assess and evaluate for feasibility of widespread use and commercialisation in South Africa; iii) Provide safe and adequate sanitation facilities, particularly in undeveloped rural areas which lack infrastructure.


Objectives of SASTEP:

i) Demonstrate technologies in phases; ii) Provide hard evidence on performance; iii) Provide hard evidence on impact; iv) Iterative feedback to technology developers; v) Catalyse and orient sanitation industry towards water saving and beneficiation systems.

Objectives of the RTTC (Reinvent the Toilet Challenge of the Gates Foundation):

• Disinfect human waste • Recover resources from human waste • Less than US$ 5 cents per user per day • ‘Off the grid’ • Self sufficient
For details see: www.susana.org/en/resources/library/details/1636


Short description of the project:

The Department of Science and Technology (DST) South Africa and the Bill & Melinda Gates Foundation (BMGF) recently announced a Memorandum of Understanding (MoU) – “Partnership in the Demonstration of Sanitation Solutions in Rural and Peri-Urban South Africa” at The Reinvent the Toilet Challenge Fair in Delhi, India. The MoU outlines the cooperation between the two organisations towards achieving sanitation delivery through the implementation / application of innovative sanitation solutions.

The DST has committed ZAR 30 million (~US$ 3.0 million) over two years to fund the implementation and field-testing of innovative sanitation technologies and approaches in South Africa. The technologies to be demonstrated were developed through the BMGF’s Water, Sanitation and Hygiene (WSH) programme, in particular, those from the BMGF’s Reinvent the Toilet Challenge. The BMFG WSH programme is contributing US$1 million to support the testing of technologies selected. The lessons learnt through the demonstration of these solutions will be shared with the global community.

The South African Water Research Commission (WRC) will serve as the implementing agent for the demonstration programme. Enquiries of interest are welcomed to potential BMGF grantees who feel that their technologies are ready for demonstration.

Two technologies from the RTTC have been confirmed for installation in 2016:

1. Caltech: Self-contained, PV-powered domestic toilet and wastewater treatment system (forum.susana.org/forum/categories/105-pr...te-of-technology-usa)

2. Critical Practices: EarthAuger urine-diverting dry toilet (UDDT), see here on the Forum: forum.susana.org/forum/categories/34-uri...and-other-countries. Two-hundred units have been delivered to South Africa and will be ready for use by mid-2016.

Previous discussion on forum about EarthAuger toilet in Ecuador: forum.susana.org/forum/categories/106-us...on-in-terris-ecuador


SASTEP is not limited to these two technologies, as SASTEP aims to demonstrate up to five technologies over the duration of the programme. RTTC innovators* who have a near-final product or processing unit (back-end treatment system) are welcome to contact Mr.Stuart Woolley.


Research or implementation partners: The organizations whose technologies were selected for demonstration

Links, further readings – results to date:

Current state of affairs:

The first technology to be demonstrated is the EarthAuger. 200 EarthAuger unitswere in South Africa and and transported to the a rural municipality where the demonstrations are taking place. SASTEP is engaging in community work in order to ensure the acceptance of the technology to aid the success of the demonstration programme.
After the initial demonstration of a few months, we'll see if the units need any further development or if they're suitable to proceed to a more widespread demonstration in other rural areas that don't have experience with similar programmes.

For technologies where the demonstrations are successful (w.r.t. performance, user acceptance and suitability) we will begin a process of developing a strategy for commercialisation, localisation of manufacturing, and otherwise stimulate the local private sectors for uptake of these technologies.


Biggest successes so far:

Mobilising rural communities to accept and support the demonstration programme, achieved through rigorous social interaction and facilitation.


Main challenges / frustration:

Importing of new technologies for demonstration which are not classifiable by national bureaus of customs and excise.


* "RTTC innovators" is defined here specifically as those developers that were a part of the original BMGF Reinvent the Toilet Challenge. Technology developers of similar technologies would be able to negotiate with us directly for opportunites to demonstrate under other programmes with other sources of funding.

Stuart]]>

Title of grant: ADPL (Anaerobic Digestion Pasteurization Latrine) Duke Biogas toilet

Subtitle: Further development of the Anaerobic Digestion Pasteurization Latrine, a simple, energy neutral self-contained sanitation technology relying on anaerobic digestion and heat pasteurization of the treated effluent.

  • Name of lead organization: Duke University
  • Primary contact at lead organization: Aaron Forbis-Stokes
  • Grantee location: Durham, NC, USA
  • Developing country where the research is being tested: Units are currently being tested in Kenya, India and the Philippines.
  • Start and end date: November, 2015 – March, 2017
  • Grant size: $ 341,337 (see BMGF grant database here)

Short description of the project:

This is a continuation of the research begun in 2011 which was funded by a previous GCE grant. In this phase, it is our objective to fully assess the potential of the ADPL to meet the Foundation’s criteria for Reinvented Toilets. We are intensifying monitoring efforts of our current five ADPL units in Kenya, India and the Philippines, improving implementation and operation, and redesigning the heat pasteurization system for improved efficacy and reliability.


Goal(s):

Provide a sanitation system for an extended household of 5-30 users based on an anaerobic digester that produces sufficient biogas to heat pasteurize the daily effluent flowing out of the digester. Sufficient biogas production and an efficient pasteurization system design will result in an energy self-sufficient solution. Effluent should be safe for on-site land application. Means of further improving the water quality of the effluent will be investigated.


Objectives:

  1. Actively maintain our five existing ADPL systems, expand scope and quality of monitoring
  2. Redesign heater-heat exchanger system for improved efficiency
  3. Improve biogas production through better digester design
  4. Develop means to achieve superior effluent quality for reuse (other than direct land application)
  5. Work with partners towards integration of the ADPL concept, aim for STeP evaluation or extended demonstration of resulting product(s)

New Baffled Anaerobic Digesters For Eldoret ~ April, 2016

Two fixed dome anaerobic digesters designed by Aaron Forbis-Stokes using computational fluid dynamics were manufactured by Specialised Fibreglass in Nairobi and installed at the Eldoret North and Central sites. The new baffled design will improve average residence times and reduce solids in the effluent stream going into the heater and heat exchanger. The new digesters have four chambers and sampling ports for taking core samples and assessing solid deposition levels.


Biggest successes so far:

Installed new baffled digesters for improved solids retention, tipping buckets for flow rate measurement and Particle controller boards for more reliable control of heater temperatures and temperature monitoring in Eldoret, Kenya in April. Plans in place to roll these upgrades out in the Philippines and India this summer and early fall. Improved pasteurization system design underway.


Main challenges / frustration:

Managing suspended solids in the effluent, guaranteeing pasteurization holding times and temperatures during peak usage periods and consistently generating sufficient biogas to run the system on an ongoing basis.]]>
