This module introduces the principles of the circular economy and demonstrates how they can be effectively integrated into Vocational Education and Training to promote sustainability and resource efficiency. It explores key concepts such as waste prevention, reuse, recycling, sustainable product design, and the waste hierarchy, while examining their relationship with European policies, labour market needs, and local environmental challenges. Through practical activities, digital tools, collaborative learning, and real-world case studies, participants develop the knowledge and skills required to incorporate circular economy principles into teaching practices, institutional strategies, and sustainable waste management initiatives.
