Re: Urine concentration (building a network of actors working with urine concentration)

Good idea.

In our test garden I used diluted urine and Vuna AURIN Swiss Concentrate with similar results.

The application is precise with the Solar-Dripper.

We had remarkable sugar levels (12.2 °Bx) and very large production last year.

The tests are ongoing this year with Kong F1 Sunflowers, squash and corn.


We are now selling complete tool kit for R&D test gardens and schools  at 212 € for 68 plants with an adjustable drench gun, bottles and 2 baskets.

The Solar-Dripper is compatible with any type of urine concentrates or chemical fertilizers for comparison.


The drench gun is ajustable from 0 to 70 ml of urine or concentrate for fast and repeatable tests.

Re: Urine concentration (building a network of actors working with urine concentration)

We (Swedish university of Agricultural sciences) have installed two urine-diverting Save! Toilets (designed by EOOS and manufactured by Laufen) as the front-end solution to our back-end technology and I get a lot of people asking how does it work?

Here's a video by Laufen (
).

I know #EAWAG , in Switzerland, have installed several too. So far I have only heard good things about the Save! Toilets. Does anyone know of other installations and have comments on their experience/performance?

Re: Urine concentration (building a network of actors working with urine concentration)

Hello Jenna

On my side in France we do not use a diversionary toilet.

I am concerned about latent urine clogging.

And a diversion toilet does not completely prevent cross-contamination with feces.


We use simple plastic bottles to urinate directly into.

Bottles are free. We close the cap after.

I just installed a bucket for urine bottles next to the conventional toilets.

The total cost of this collection facility is less than € 5.

There is no possible cross contamination.


To prevent odors, urine is used from bottles in the garden or spread under our trees almost every day.

For urine transformation the bottles system can be emptied in a collection tank ( 10L  to 20 L or more) for transportation to the next process facility. Again rincing collection tank after each use prevent odor.


The bottles are rinsed each tyme they are emptied and they can be reused for several weeks. 

We often change bottles because empty plastic bottles are everywhere.

For women, the use of an adaptor allows the same system to be used.

I designed the SYMBIO collector curently under test.
