Purpose and goal
The purpose of the project was to gather and create a consortium to strengthen the understanding of how a urine dehydration system can be implemented without major commitments of stakeholders. An important conclusion is that most water closets can be replaced by urine separation toilets with a drying chamber that is placed in the toilet space. The aim of the project was to secure that the system solution is ready for pilot studies. The first prototype is already tested and pilot studies will be started during spring 2018 in the cities of Malmö and Lund.
Expected results and effects
The project members are ready to apply for a collaboration project. A cooperation has started with two toilet construction companies, which manufactures prototypes for testing at a larger scale. Research and optimisation of the toilet configuration and drying chamber are still underway, but more prototypes will be delivered for pilot testing. The market analysis revealed some challenges, which will be highlighted in the collaboration project.
Planned approach and implementation
Two project meetings have been accomplished to discuss and analyse the system solution. The project has arranged two open workshops about i) toilet configuration and ii) agricultural needs, respectively. Five different toilet constructors attended the first workshop. The second workshop attracted only one farmer and no mineral fertiliser producer. Except these meetings and workshops, development of the system solution has been performed as well as market and external analyses.
