Here are a couple of pictures of recycling collection in Spain from Cuenca…in the main plaza, and in Segovia. In space constrained Europe, this underground collection method saves space, is more attractive and fits into the historical areas of town without becoming a eye sore…. Materials collected includes glass, containers (plastic bottles, tetra pak and cans), paper and cardboard together, and organic residuals.
