From greywater to groundwater through decentralized green technologies. A living lab for the sustainable and safe recovery of water in agricultural systems (GGSolutions).

The GGsolutions project promotes innovative solutions based on circular economy and sustainability to address challenges such as water scarcity and waste management in urban environments. It proposes reusing alternative resources, such as greywater and sludge from households and industrial laundries, through experimental green wall installations that enable their use for irrigating urban gardens. The project also promotes the use of biosolids and organic compounds as natural soil fertilizers.

The project will study the efficiency of green walls and composting systems in removing chemical contaminants such as pharmaceuticals, personal care products, microplastics, and pesticides. It will assess the fate of these contaminants in treated water and soil, as well as their potential impact on crops and groundwater.

Using a “Living Lab” approach, GGsolutions aims to foster more sustainable urban agriculture by reducing environmental impact and improving cities’ resilience to climate change and pressure on natural resources. The project has a total budget of €182,500 and is led by Gianluigi Buttiglieri and Sara Rodriguez-Mozaz, with the participation of Joaquim Comas, Maria Pau Garcia Moll, Diana Alvarez, and Sara Insa.
