DESIGN
Développement et Evaluation de Scénarios Urbains Innovants de Gestion Séparative des effluents
The DESIGN project is funded by the French National Research Agency (ANR) on the main societal challenge: Mobility and sustainable urban systems. It aims to develop and evaluate innovative scenarios for source separation and wastewater recovery. The challenge of the project is to evaluate the real benefits and constraints of these alternative approaches by integrating different criteria:
- on the environmental level, by evaluating the different solutions through life cycle analysis;
- from a technological and economic point of view: by developing key technologies for new sectors, i.e. vacuum toilets that do not currently exist, a new technology for recovering ammoniacal nitrogen to produce a fertilizer; (see N and P recovery theme)
- from a sociological point of view, by measuring the capacity of appropriation of these new devices of management of human discharges and decentralized systems by the communities, the users and the professionals of the urban environment;
- finally, from an urban planning point of view, by assessing the suitability of source separation scenarios for different urban typologies.
The DESIGN project brings together two research laboratories, two design offices specialized in the environment, and two companies developing innovative equipment.
