Making innovative biofertilizers from urban waste, agro-food waste and volcanic ash: this is the goal of LANDFEED, a new European project that ENEA is presenting at ECOMED, the fair dedicated to environmental technologies and energy systems for the Mediterranean, being held in Catania, Italy, April 15-17. The project aims to recover valuable nutrients from waste materials to reduce waste, promote sustainable agriculture and contribute to food security. As explained by ENEA researcher Antonella Luciano, LANDFEED also aims to create a European market for biofertilizers, today largely dependent on imports. Innovations include an industrial symbiosis platform to facilitate the sharing and management of by-products between companies, and a "digital passport" to ensure traceability of biofertilizers. In addition, chitosan and microalgae-based coatings will be developed that will allow controlled nutrient release, improving fertilizer efficiency and reducing environmental impact.
