The European circular economy action plan, launched in 2015 includes a group of measures aligned with the 3r principles. To meet recycling goals, valuable materials such as aluminium must have packaging that helps to increase their recycling rate above the current 45.6%. This recycling rate could be improved with the help of current consumers and the education of future generations. In this way, the aim of this study is to prove the positive effects of childhood education in the circular economy by teaching sustainable practices in the case of aluminium packaging recycling. The study was conducted in the form of a survey, with data being gathered via questionnaires carried out pre and post workshop in schools of different regions of Spain in students between 8 and 12 years old. This study provides an exciting opportunity to advance our knowledge of the use of workshops to increase children's knowledge, awareness, and intention of recycling.
