There really is no problem with smell coming from these simple, portable urinals made from bottles. The mouth of the bottle is narrow and wind across it is blocked by the upper bottle that forms the funnel. It is important to empty them as soon as feasible and rinse them with water to avoid smell developing over time. Any odor is truly minimal and certainly within the range of any other acceptable models.

Advantages include that the necessary bottles may likely already exist in these camps and the inhabitants could help to put them together.

The key thing is that it can be used wherever there is sufficient privacy and then be emptied on the soil wherever there are plants that need fertilizer. It seems that the other models do not lend themselves so well to spreading the urine.

I suggest you try it yourself.

I hope this is helpful. Let us know how things go and if we can be of any further help.

Best wishes,
Chris Canaday]]>

@Canaday. I think your bottle urinal is interesting. Do you have any experience with it and how to best avoid the odor?

@Elizabeth. Susan Design has the best technology for this pilot project, however I wanted to explore others and possibly test Susan Design Urinal and another technology at the same time. The pilot is a test to see if we can reduce water consumption in emergency response in Iraq (and eventually across the Middle East), as well as reduce environmental pollution by reusing the waste instead of dumping it. We want to reuse the urine as fertilizer in either agricultural production, or tree planting. Funding is still undetermined. We are gathering partners that can fund various parts of the pilot -urinal production, collection and transport, reuse scheme. We are still in the feasibility stage of the project so a lot is yet to be determined.

@JKMakowka. We are primarily serving people living in transitory situations, where we need to have highly transportable and simple technologies that do not require installation of any kind. Your suggestions would work very well in camps however.

@Carol. The Iraqis in Kurdistan are actually from provinces where the fighting with ISIL is happening, and these are mostly rural areas. Therefore they are generally more open to makeshift sanitation facilities than the other emergency populations in Kurdistan, such as the Syrian refugees who come from the cities. A question. How do you combat the odor in your pee buckets?

Thanks again to you all! I will update this forum once the project is underway.]]>

Here in my Laboratory in Cameroon, we have already worked on struvite production.
The best information here is about struvite reactor which can be built with locally available materials and it low cost.
Thanks

There are many ways to treat and reuse urine. Rich Earth Ostara's production of Crystal Green is a very high tech, commercial, proprietary option usually incorporated into large waste water treatment systems. Expensive.

For a lower tech solution see the STUN reactor used to produce struvite for fertilizer in Nepal. www.eawag.ch/forschung/sandec/gruppen/ew...uvite_production.pdf

And as Abraham notes, Rich Earth Institute is sanitizing urine for reuse in structured experiments through "storage or pasteurization". I hope he's say more about these basic procedures that we may be able to replicate in other communities.

All the best with your continuing investigations at Ecodomeo.

We are just beginning trials to incorporate urine into a solid product by co-composting it with other dry materials.

thank you for all this information.
If I understand correctly, there are 2 existing systems :
The Vuna project :
* concentration of urine on one side
* pilot project
* cost about 80 000€

The Pearl Process from Ostara :
* production of solid fertilizer from wastewater
* industrial process
* I asked for a cost of a small machine

I thought there was also a german producer of machine transforming urine in a solid fertilizer.

I try to see if it is possible to start a business transforming urine. The 2 options above seems good for me.

This sounds very interesting ... and there is still ample room for more innovation in UDDTs (and I have a number of ideas on this).

Is your plan to sell prefabricated UDDTs, complete with privacy structures, that can be shipped wherever and put together?

What is your target market?
What is your target price?
What materials would you like to use? (Any chance of including post-consumer "waste", such as plastic bottles, TetraPak or recycled HDPE?)

Je ne suis pas francais, mais j'ai vecu un an au Québec et je peux lire bien.
(I am not French, but I lived in Quebec for a year and can read well.)

We look forward to learning more about your project.

Je dois dire que ton message aiguise notre curiosité.
En essayant de lire entre les lignes, tu semble rechercher des techniciens spécialisés dans la techniques des UDDT et des financeurs pour ton programme. Les deux catégories consultent les discussions de ce forum, je crains toutefois que seul la première soit vraiment réactives à tes demandes. Ta cible semble le milieu urbain des pays développés.
Je travaille sur ces thèmes en france et je t'invite à jeter un oeil à notre projet qui est en test actuellement (projet ecosec).

Pour rejoindre Elizabeth, avec un peu plus de détail sur les origines du projet, ton background, la localisation et le contexte du lieu d'implantation, etc ... tu auras plus de chance d'avori des réponses.

Hi Jorg,

I must say that your message raise our curiosity.
Trying to read between the lines, you seem to look for technicians specialized in UDDT and funders for your program. Both categories consult threads in this forum, I am afraid, however, that only the first would be truly responsive to your requests. Your target seems urban developed countries, right ?
I work on these issues in France and I invite you to take a look at our project which is currently in test (Ecosec project).

To follow Elizabeth, with a little more detail on the origins of the project, your background, location and context, etc ... you'll have more chance of get answers.

Welcome to the forum! Could you please clarify what you have in mind with a "commercial public udd-toilet project"?

I presume that udd stands for urine diversion dehydration, i.e. without flushing?

If it's going to be a commercial enterprise then why call it a "project"?

Why the Asian market and not first in France or Germany? Test it out at home first? Or which part of the Asian market do you have in mind? Urban? Low income?

Have you looked at the work by Eram Scientific in Kerala, India (their toilets are conventional toilets though, but also public toilets for the urban market in India):
forum.susana.org/forum/categories/105-pr...ram-scientific-india

I guess you already have a business plan? What is your niche? How much would you charge for using the toilet?

In terms of research groups, I reckon if you have a look at the SuSanA partners in Asia you might find some interesting organisations:
www.susana.org/en/partner
(use the filter function on that page)

In China, consider Beijing University (contacts are Zifu Lee and Heinz-Peter Mang), and there are also other research groups which had funding by the Bill & Melinda Gates Foundation, e.g. this group seems to be doing innovative sanitation work:
Shijiazhuang University of Economics/Beijing Sunnybreeze Technology Inc in China

forum.susana.org/forum/categories/105-pr...ijiazhuang-uni-china

Do tell us more, unless it would give away too many of your business secrets of course! Good to see some private sector involvement, that's for sure.

Hope this helps a little bit but I think we need more information in order to help you better.

Regards,
Elisabeth]]>

The questions I would like to ask you :

Is there in the field of ecological sanitation technology still a potential for innovation: fecal analysis, storage, transformation, surface condition of the pipe systems ... ?

We are looking for research groups or potential promoters in Asia that may be open for a commercial, technical, strategic cooperation?

Are there any French or German speaking engineering offices or centers of excellence represented on this blog that have specialized in this issue and may support us in the technical implementation?

Does anyone know potential private or public investors for commercial sanitation projects?

Several jurisdictions in the Pacific Northwest USA have adopted a simple twin bucket system for household emergency preparedness. Research has demonstrated that coastal region of from northern California to the Alaskan panhandle is at risk of a Cascadia Subduction Zone quake that will destroy pipes. Official hazard assessments show that an 8.5 M quake will disable urban water systems for six months but sewer systems for nearly three years.

The impact of the quake that struck in Christchurch, New Zealand bears out this recovery timeline. And it is the citizens of that city that took matters into their own hands and adopted UD with a simple to bucket toilet system: A PEE bucket is coupled with a POO bucket. www.composttoilets.co.nz Having lived in Iraq, I think likely that your IDPs are from sophisticated urban milieu and will appreciate seeing photos of these lovely bathrooms in New Zealand.

The Portland, Oregon group PHLUSH (Public Hygiene Lets Us Stay Human) adapted the Twin Bucket Toilet for emergency preparedness.



You can find links to our leaflet, video, exhibit kits, displays and the Sewer Castastrophe Companion, with instructions for composting and reuse here. www.phlush.org/emergency-toilets/

By the way,we also really like the free minimalist urinal that Chris Canaday refers to as well as the ones by SuSan Design that are mounted on 20 litre containers.

Best wishes to you as you address the needs of your IDP community. Please let us know how things go.

I was going to suggest to you the plastic urinal from Addicom (South Africa). I thought that Wolfgang Berger's company is marketing them in Germany, and I found this information on this website:
www.berger-biotechnik.com/dry-urinals/-u...nus---dry-urinal.php



Mind you, I am a bit surprised at the high cost (187 Eur), as the model in South Africa sold for much less (20 Eur I thought?). Perhaps Wolfgang can tell us how this price difference came about (higher quality?) and if it selling well in Germany. Also, Wolfgang, please tell us more about the "membrane trap" that you are selling, is it the Addicom Eco Smellstop?

Here the information from Addicom's website in South Africa:



www.addicom.co.za/waterless-urinals.html

But I have no idea how fast they could deliever and in which quantity.
All I know is that I have one of them at home since several years and it simply works and works and works:

This is what I call a modern bathroom by Sustainable sanitation, on Flickr

Mind you, you asked for a uni-sex urinal. I guess it is not quite the right shape for females to use comfortably.

This one from Separett (their camping model) could be used to collect the urine from females easily and cheaply:

Foldable camping UDD toilet by Separett (Sweden) by Sustainable sanitation, on Flickr

Could you tell us more what you meant with: "we are working with SuSan-Design.org portable urinals, so already aware of that option."

We have a report about them here in the library (from 2011):
www.susana.org/en/resources/library/details/1048

Please tell us more about your project? Why do you want to collect the urine in the first place? Who is funding this?

Here is an extremely inexpensive and accessible option that can be made with plastic bottles that likely already exist in these camps:
