Breathing iMETland innovation into the local environment and communities

The iMETland wastewater treatment device is being constructed to fully benefit from natural biological processes and to mimic nature’s way of generating new ecosystems from urban wastewater.

iMETland innovation partners experienced the device’s potential in Seville, when the project consortium gathered for the second time. The unique landscape offered by Fundación CENTA provided an opportunity to assess how iMETland has been progressing and to get a taste of the project’s ultimate outcomes. The scientific debate focused on the composition of the electro-conductive material and on the main scope for designing a suitable environment to maximise electroactive bacteria behaviour with MET technologies. In parallel with scientific innovation, the project team used the opportunity to assess two non-technical benefits: its landscape beautification potential and its service to the small community of Carrión de los Céspedes, ultimate users of the unit. The two aspects enabled to grasp the iMETland purpose of not only safeguarding local environment, but also designing an eco-friendly device able to create a new biological ecosystem, adorned with ornamental plants, colorful flowers attracting birds, and, finally, contributing to place its units at the level of nature. iMETland was born locally, for the advantage of the local environment and communities. As Juan José Salas, Fundación CENTA director, explains “Carrión de los Céspedes is proud to have been selected as a pilot location for iMETland, alongside the municipalities of Orbi (Denmark), Mar del Plata (Argentina) and Jiutepec (Mexico). It is an exceptional opportunity to spread internationally”. Ultimately, it’s about learning from nature how to restore water purity for small communities. We are designing an innovative tool drawing on a virtuous combination of water, energy, ICT and land resources. Its application potential extends far beyond the geographical location of the four units and its innovative technologies will help preserve nature and treat urban wastewater without energy costs, providing pathogen-free water suitable for irrigation and bringing people closer to their local environment.
