Hi Eric,
I completely agree that urine fertilizer is working very well in conjunction with compost.  You will find some of my recent experiences in Germany concerning Central European fruits, in particular, under that link:
forum.susana.org/urine-treatment/25964-c...nutrient-cycle#35136
Earlier, I have worked in Uganda where I have promoted ecological sanitation toilets in Adjumani in the North.  You will find attached the recommendations that were developed over the years in that regard.  It includes application rates for both compost and urine.
@Loures, I would agree that the direct use of urine as a fertilizer (after some time of storage for hygienization if need be) is more for a smaller scale, but let us start with a small scale first before we think of a large scale!  After that we can think of concentrates, or granules, or even of pumping treated waste water on a larger scale, or whatever.
Kind regards, H-A

Hi Bhaskar,
Thanks but it's not in our plan. Target is only fertilizer.

Hi

Have you considered using Urine in water to grow Diatom Algae and Fish?
This is simpler than using Urine as agricultural fertilizer.

You just need to pipe the sewage to a tank or pond or lagoon and grow Diatom Algae and Fish.
The tank / pond / lagoon volume has to be about 30 days of daily sewage flow.
So if daily sewage flow is about 1,000 liters, tank volume needs to be about 30,000 liters. 

Thanks Lourdes,
Yes this can be realy interesting if we can have Cost-Benefit Analysis document.
Regarding solid product, we plan to create another project very soon, but to begin liquid product is our only solution (nitrification and fermention of urine can be only liquid). "solid product is much more accepted than the application of a liquid product" does it come from your own experience our same vision as most countries ?

We have implemented a urine treatment plant in the city of Alto in the department of La Paz in Bolivia.
Because the cost of transporting a solid product is much more economical than the transport and marketing of a liquid product. And the same application of a solid product is much more accepted than the application of a liquid product.
When we have the Cost-Benefit Analysis document from that experience, we will translate it into English and share it with you. Meanwhile I share the video 1 and video 2  of the Urine Plant.

Nosotros hemos implementado una planta de tratamiento de orina en la ciudad del Alto en el departamento de La paz en Bolivia.
Por que el costo de transporte de un producto solido es mucho más economico que el transporte y comercializacion de producto liquido. Y la misma aplicación de producto solido es mucho mas aceptada que la aplicacion de un producto liquido.Cuando tengamos el documento de Analisis de costo y beneficio de esa experiencia, la traduciremos al inglés y la compartire con ustedes. Mientras tanto les comparto el video 1  y video 2 de la Planta de orina.

In Madagascar, as in many developing countries, waste management and food security are major challenges. In a context where access to toilets and adequate sanitation systems remains limited, especially in disadvantaged rural and urban areas, an opportunity presents itself: transforming human urine, often an ignored or poorly managed waste, into a valuable resource for agriculture .

We need some help with our crowdfunding: fundrazr.com/EcoFertilys-Madagascar

For months, we have been working on several theoretical approaches that we are now developing with our biologist. Our main goal is to partially fund a real research laboratory with these funds .
Thus, we will be able to quickly provide research results to various donors to move to a stage of large-scale collection and production.

Any help is welcome !
