With this project we wanted to empower youth (with real examples) to create their own social entrepreneurship projects in the environmental field, without the need for a large economic investment, and thus helping to mitigate the labor and housing problem. The objectives of the project were: 1. Promote the entrepreneurial spirit of young people with projects of bio-construction, transformation and reuse of rural and urban waste, and renewable energy. 2. Empower participants by giving them the necessary training (theory, tools, techniques) to start bio-construction projects, renewable energy, reuse waste and permaculture. 3. Provide participants with entrepreneurship skills to develop their own ideas and projects. 4. Disseminate sustainable housing alternatives and building systems with a negative carbon footprint and promote a healthy lifestyle, responsible consumption and aware. 5. Make the participants aware of the real effects of our current consumption and life habits by creating a space for reflection and debate about the sustainability. 6. Promote European programs such as Erasmus + giving a special focus to youth development and initiatives and projects.
