Two short online courses have been elaborated by GREENUS consortium in order to improve awareness on the importance of correct waste management and the consequences of no-recycling policies. Each course consists of 5 videos, based on the MOOCs model (Massive Open Online Courses) where professors and staff involved in the project give information about different aspects of waste management and the importance of recycling. The videos have been developed to be disseminated to the academic community as well as to the general public without a specific technical background.
