Re: Looking for contacts from Norway and North America, Public dry toilets in recreational wilderness areas

Hello Lauri,

Looking to introduce dry toilets in Belgian natural parks myself, I am very interested in your thesis.
  • Do you have more (articles, ...) to read in english on your conclusions?
  • Or can you pass me links to the best practice examples you found?
  • I wondered if you found a dry toilet system that composts urine and solids together and excludes any risk of contaminating the soil of the place where it is located. 
Thanks very much,

Geert

Re: Looking for contacts from Norway and North America, Public dry toilets in recreational wilderness areas

Hi Geert,
Thank you for your interest towards my thesis. Unfortunatelly there isn’t any published articles about my thesis in english but I am happy to tell more about my conclusions. You can also send me aprivate e-mail if you are interested lauri.varrigmail.com.

In my thesis I found out that toilet waste management and especially preventing negative impacts from dry toilets to environment (eutrophication and hygiene) is very complicated thing. Especially when working in a cold or freezing climate. Also one big issue is the national environmental legislation and the common interest to  solve the waste problem that exists but still is in the shadows of common interest.

I recommend you to check Toilet Tech Solutions website https://www.toilettech.com/  and learn about their system to handle toilet wastes.

Founder of Toilet Tech Sytems Geoffrey Hill has done also an interesting research   https://open.library.ubc.ca/cIRcle/collections/ubctheses/24/items/1.0073570  that you should check. Information from Geoff (earlier messages in this discussion) gave me a lot new ideas for my study.

I think that Geoff´s idea to use a small scale septic field (presented in his thesis) for urine is a best available technology for handling the liquid waste(urine) in remote sites(my personal opinion). Only “weak” factor is that this system needs the urine diverting toilet system that isn´t available on every site. Like in Finland and Sweden, urine diverting toilets that actually diverts urine outside the toilet or actually work in cold climate are very rarely seen on public sites. Normally urine and feces are mixed together and the liquid waste is leachate in Finland and Sweden. Nevertheless, I see that Geoff´s idea to treat urine in small septic field has a great potential and In my interest in a
future is to test this system for leachate.
 
In my thesis´s conclusions I am trying to emphasize that it is important to look the bigger picture and not just one toilet. How to solve and manage the toilet wastes of the whole area? How the toilets are situated in respect of service connections(roads, etc.)? In some cases (high use, near roads)  the septic tank toilets and transporting the waste to local waste treatment plant might be the best solutions  although it is quite expensive and not very sustainable. How to manage waste from remote sites? Treated on site or transported to centralized treating unit? Liquid is always problematic to transport so it should be treated always on site at least on remote sites. Feces however could transported more easily for centralized treatment units like bigger composting unit etc.

One promising system for treating toilet waste in centralized unit (doesn't mentioned in my thesis) is microthermal process that can handle also septic waste (if I have understood correctly). Finnish company (Digital Toilet Systems Oy) has available technology for this and the system can treat toilet waste in 1-2 days and turn it to a hygienic fertilizers. Unfortunately there is only website in finish https://www.dtso.fi/ Founder of the company is a Raini Kiukas and she has done a long career in dry sanitations related matters in Finland. The company is also on their way to bring out some new systems for urine treatment.

I hope I was able to answer at least some of our questions.

Cheers,
Lauri

Hi Rochelle,
Somehow I have missed your messages. Sorry about that.

I managed to complete my thesis in June 2020 but I am always interested to learn more (and get more contacts) about public sanitation in wilderness areas. Thank you for your advice.

Cheer,
Lauri

Dear Lauri,
Thanks for your posts! Could we upload your thesis to the SuSanA library (doesn't matter if it's in English or in another language). If it can't be shared, could you please copy the abstract here and perhaps the conclusions chapter?
But I hope there is nothing preventing you from sharing your entire thesis with us.

The topic is important and we don't have much material on it yet in the SuSanA library or here in the discussion forum.

Thanks,
Elisabeth

Hallo,
Norway has many dry toilets since Norwegians have many cabins. At the University of Live Sciences (NUMB) there is Prof. Peter Jenssen who may be able to help you. You can send him a mail: Petter D.
