Tack Porin Prikaati: slutförandet av urintorkningspilot i Säkylä

Den tre månader långa urintorkningsinstallationen vid Pori Birgade i Säkylä, Finland, demonterades förra veckan och avslutade den första fältdemonstrationen av vår teknik. Som du kommer ihåg från våra tidigare blogginlägg integrerade vi en urinuttorkningsmodul med kapacitet att behandla 40 L urin / dag / m2 i ett befintligt, mobilt torrt sanitetssystem – Biomajatoaletten. Under denna pilot har vi samlat prover av slutprodukten / gödningsmedel (se bilden nedan), kontrollerat olika fysikaliska och kemiska egenskaper samt energianvändningen av behandlingsmodulen. Under de kommande månaderna analyserar vi de samlade proverna tillsammans med våra partners i Finland. Medan modulen fick mindre urin än dess konstruktionskapacitet fungerade den smidigt under pilotperioden.

Halv-separerad alkalisk urintorkning i en stadsbyggnad

Under den senaste veckan har gruppmedlemmarn Prithvi Simha och Giulio Zorzetto varit i Tammerfors i Finland, där de installerade en ny urinavtorkningsmodul som testas i Hiedanrantaområdet i Tammerfors. Behandlingsmodulen konstruerades på SLU, transporterades till Finland, återmonterades vid TAMK och slutligen installerad i källaren av Lielahtis herrgård. Urin från två olika toaletter i herrgården, som själv genomgår renovering, planeras att bli kopplat till detta behandlingsystem under den kommande veckan. Denna installation, som varit en gång i drift, har potential att öppna en ny aveny för lokal insamling och behandling av urin i urbana miljöer.

Semi-decentralised alkaline urine drying in an urban building

During the last week, group members Prithvi Simha and Giulio Zorzetto were in Tampere, Finland where they installed a new urine dehydrator module that is being pilot tested in the Hiedanranta neighbourhood of the city of Tampere. The treatment module was constructed at SLU, transported to Finland, reasssembled at TAMK, and finally installed at the basement of the Lielahti Manor house. Urine from two different toilets in the manor house, which itself is undergoing renovation, is planned to be diverted to this treatment system over the coming week. This installation, once in operation, has the potential to open up a new avenue for local collection and treatment of urine in urban settings.

Thank you Porin Prikaati: wrapping up the urine drying pilot in Säkylä

The three month long urine drying pilot installation at the Pori Birgade in Säkylä, Finland was dismantled last week, bringing to an end the first field demonstration of our technology. As you’ll recall from our previous blogs, we integrated a urine dehydration module with capacity of treating 40 L urine/day/m2 into an existing, mobile dry sanitation system – the Biomaja toilet. During this pilot, we have been collecting samples of the end-product/fertiliser (see picture below), monitoring various physico-chemical properties as well as energy consumption of the treatment module. Over the coming months, we will be analysing the collected samples, along with our partners in Finland. While the module received less urine than its design capacity, it functioned smoothly throughout the pilot period.

Nuevo proyecto piloto de secado de orina en Finlandia

Tras la experiencia exitosa del proyecto MORTTI, en el cual se por primera vez la tecnología de deshidratación de orina desarrollada por nuestro grupo se puso a prueba en condiciones de campo, estamos de regreso en Finlandia una vez más durante esta semana. En esta ocasión, estaremos construyendo e instalando una unidad deshidratadora de orina, misma que será conectada a un urinario seco y a un inodoro de recolección separativa. El sistema será instalado en la mansión Lielahti (vecindario de Hiedanranta, ciudad de Tampere), habiendo sido diseñado para tratar casi 25 litros diarios de orina por un período de 3 meses. El proyecto está siendo llevado a cabo conjuntamente por nuestro grupo y Sanitation360, una compañía iniciada por nuestro grupo y basada en nuestra universidad que trabaja con deshidratación de orina. Nuestros socios en este proyecto incluyen a la Ciudad de Tampere, la Universidad de Ciencias Aplicadas de Tampere y el Instituto Finlandés de Medio Ambiente. ¡Publicaremos novedades al respecto!

New project piloting urine drying in Finland

Following the successful wrap up of the MORTTI-project that piloted the group’s urine drying technology in field conditions for the first time, we are back in Finland once again this week. This time around, we will be constructing, installing, and integrating a urine dehydrator with – a dry urinal and a urine-diverting flush toilet. The system is scheduled to be installed at the Lielahti Manor in the Hiedanranta neighbourhood of the city of Tampere, and is designed to treat nearly 25 L of fresh urine/day for a period of 3 months. The project is being carried out by our group and Sanitation360, the group’s university-based startup company working with urine dehydration. Our partners in this project include the City of Tampere, Tampere University of Applied Sciences, and the Finnish Environment Institute. More updates to follow!

Half-time PhD Seminar, Prithvi Simha: Alkaline urine dehydration

On 26th April, PhD Candidate Prithvi Simha presented his half-time seminar, “Urine Dehydration Technology for Decentralised Sanitation Systems” at SLU. In the seminar, Prithvi summarised and discussed two research papers & a draft book chapter on urine dehydration. Åke Nordberg, Assoc. Prof. in Bioenergy Technology was the opponent at the seminar.

Orina deshidratada de Sanitation360: semifinalistas en el Reto de Agua FAMAE

Este año, los miembros del grupo Kretsloppsteknik de SLU iniciaron “Sanitation360”, una empresa nueva que apunta a comercializar la tecnología de deshidratación de orina que se está desarrollando en SLU. Como Sanitation360, participamos en el Reto de Agua FAMAE (“¡Agua Preciosa!”) donde el objetivo era diseñar un producto o servicio simple e innovador para conservar el agua, hacerla más limpia y accesible para todos. El innovador inodoro deshidratador de orina de Sanitation360 fue seleccionado entre los semifinalistas de la competencia, es decir entre los TOP 100 de más de 3,000 candidatos de 120 países. Según el jurado, nuestro “inodoro de captura disruptiva de fósforo convenció al equipo y al jurado”.

FAMAE es una fundación familiar independiente que apoya la innovación con propósitos ambientales. La fundación organiza cada año un desafío internacional para ayudar a los inventores a crear soluciones simples e innovadoras que puedan mejorar sustancialmente nuestra vida diaria, mientras reducen significativamente nuestras huellas ambientales.

Urine drying from Sanitation360:Semi-finalists at the FAMAE Water Challenge

This year, members of the Kretsloppsteknik group at SLU started Sanitation360, a startup company which aims to commercialise the urine dehydration technology being developed at SLU. As Sanitation360, we participated in the FAMAE Water Challenge (“Precious Water!”) where the goal was to design a simple and innovative product or service to preserve water, make it cleaner & accessible to everyone. Sanitation360’s innovative urine dehydrating toilet was selected amongst the Semi-finalists of the competition, finishing among the TOP 100 of more than 3,000 candidates from 120 countries. According to the Jury, our “disruptive phosphorous-capture toilet convinced the team and the Jury”.

FAMAE is an independent family foundation that supports innovation in the field of environnement. The foundation organizes every year an International Challenge to help inventors to create simple and innovative solutions that can substantially improve our daily lives, while significantly alleviating environmental footprints.

Agricultural field trials on dehydrated urine – “Granurin”

Between December 2018 and February 2019, we installed and used eight family-scale urine dehydrator prototypes in Uppsala. At the end of this period, we managed to produce 40 kg of dry fertiliser (which our collegues in France call “granurin”) with a nitrogen content of 10%. We thus managed to dry nearly 500 L of urine, which is what an average person urinates in a year. This fertiliser is now being applied and tested as part of the AGROCAPI project, where the intent is to ‘study the agronomic valorization of products resulting from urine source separation’. The trials are being carried out in France by Tristan Martin and colleagues at the Institut National de la Recherche Agronomique (INRA).
