With this project we wanted to empower youth (with real examples) to create their own social entrepreneurship projects in the environmental field (with bioconstruction and waste transformation) without the need for a large economic investment, since the raw materials used are considered waste today; and thus contributing to mitigate labor, environmental and housing problems. The main objective of the activities that we develop during the week is to train and empower young people to see that it is possible and thus feel capable of generating their own income by creating their own business through waste transformation projects, renewable energies, permaculture and bio-construction using urban and rural waste. This type of venture has the great advantage that it does not require a large initial investment, nor does it depend on industrial machines, large companies or other external factors. This can have a very positive impact on their lives, generating an immediate change, since many of the young people who participated are going through stages in which they are not very clear about what to do with their lives. To achieve this objective, we carried out activities that met the general objectives of the project. We show the participants through real examples that it is possible to generate income with projects that not only do not harm the Planet, but also benefit it by absorbing CO2 during their life cycle, having a negative carbon footprint. In addition, with bio-construction, artisan and manual work is encouraged and energy consumption is drastically reduced, it is therefore much more sustainable, healthy and ecological. For example, it transforms a current local problem (currently many of the cereal residues such as rice are burned in our case) that generates CO2 and produces a greenhouse effect, into a construction without carbon footprint and with a negative carbon footprint in its full life cycle. Our objectives were: 1. Promote the entrepreneurial spirit of young people through green building, permaculture and renewable energy projects. 2. Empower participants with the necessary training (theory, tools, techniques) to carry out their own bio-construction, permaculture and waste reuse projects. 3. Provide participants with skills and training on social entrepreneurship to develop their own ideas and projects. 4. Disseminate sustainable housing alternatives, construction systems with a negative carbon footprint to promote a healthy lifestyle, responsible and conscious consumption. 5. Make the participants aware of the real effects of our current consumption and life habits by creating spaces for reflection and debate about sustainability. 6. Promote European programs such as Erasmus + giving a special focus to the development of youth initiatives.
