Overview

  • On June 5 the UN highlighted that over 430 million tons of plastic enter the environment annually, inspiring utilities to adopt circular economy models.
  • Viaqua’s eco-factory in Ourense transforms wastewater into biogas, fertilisers and renewable power while serving as a public education hub.
  • Nature-based drainage systems in Santiago de Compostela and Rojales retain more than 70 percent of microplastics and urban runoff before it reaches rivers.
  • Asturagua’s Aqualogía school program and BiObserva volunteer initiative engage students and staff in water stewardship and local biodiversity monitoring.
  • Collaborative projects such as the B3CLab biopolymer bottle initiative and regenerated water schemes for forest fire prevention showcase expanding circular solutions.
