Recycling is a highly relevant issue in environmental behavior. To make it work, it is necessary to involve people. Many efforts have been made to increase people's participation in recycling. This study proposes an informal education to raise awareness among homemakers about recycling, especially aluminum packaging recycling, using workshops and compensating the factors that act as barriers to recycling in Spain. The results are the "Spaces for Dialogue" strategy to increase knowledge, awareness, and recycling intention. The findings present the main barriers to closing the gap between intention to action, and the study highlights the role that mentors play as teachers in facilitating communication and education for sustainable development.
