A few years ago we organized a youth exchange R3 Tree and decided with our European partners to develop it and, by involving our trustful partners, share it on European ground and have a higher impact on our local communities and society. We aimed to discover more about R5 (Reduce, Reuse, Recycle, Refuse, Recover (Upcycle) principles in resource management in their communities while we better understand different cultures, their values, expectations, behavior, and communication. During the activities and debriefing, we wanted to lose some prejudice about nations and cultures and appreciate the richness of diversity and advantages of peaceful cooperation in Europe through environmental education. The objectives were to anticipate and solve problems in intercultural teams and taste intercultural cooperation while learning how to use the R5 ideas in our daily life. We intended to improve and share competence among participants; leaders and youth NGOs to develop projects in a sustainable way using a simple rule - REDUCE - REUSE - RECYCLE - REFUSE - RECOVER and create hands-on workshops to share that in practice. Those workshops were as concrete as possible so they could be applied among all partners’ projects and organizations as well as in the everyday life of the participants and their families and peers. This project aspired to create a community of “green” minded young people working on sustainable resources to the implementation of joint activities under concrete bases of an environmentally friendly approach. The methods used in this exchange were interactive and non-formal (group discussion, simulations, theater and experts’ interviews), where each participant had the opportunity to share their own experience and develop common workshops with the good practices in "Green Skills" in our countries. R5 Tree meant to empower young people and local communities for the importance of materials management and sustainable environment, from local-based economies to green-loop productions having young people as "engine" in that transformation. Despite information spreading and activities aimed to include young people to act on environmental sustainability and participate actively in local or national activities and campaigns, young people often encounter passive attitude and lack of information about issues like how to Reduce, Reuse, Recycle, Refuse and Recover materials or about possibilities for young people to participate in meaningful environmental campaigns. Our idea of conducting a youth exchange on practical environmental issues was about dealing with notions of Material Management and R5 in particular. We believed that the term "environment" had become a broad buzzword that is often used without much specific meaning and content. Therefore, R5 intended to be an attempt to approach the meaning and significance of hands-on examples and workshops. This, we believed, could not be achieved without consideration of the other realms where the environment comes into play: the local community and the nation. In summary, our objectives were the following: • To Reduce, Reuse, Recycle, Refuse, Recover material consumption in daily life through sharing good practices among young people and partner organizations; • To share knowledge about what is practicable in materials management in partners' countries through research and practice; • To create a community of “green” conscientious young people working on sustainable resources for the implementation of joint activities; • To gain and improve competences on “green skills” through creative workshops made by the participants; • To create awareness about Millennium Goals 2020 (Ensure Environmental Sustainability) and join forces in cleaning campaigns in their communities; This is also the way how the youth exchange was connected with objectives of Erasmus+ and KA1. The Youth Exchange contributed to the improvement of the skills and abilities of young people, including those with fewer opportunities, improving social inclusion, intercultural and environmental awareness, and cultural and linguistic diversity. The youth exchange helped to develop participants’ skills in working for a common sustainable community and, therefore, promote actions on European citizenship and EU's core values as democracy, human rights and social inclusion and integration of environmental campaigns by making young people more active and responsible for and in the society.
