The climate challenges we are facing are growing as a result of our summary consumption pattern of extracting, manufacturing, consuming and throwing away. The planet counts today 1.2 billion individuals between 15-24 years old, a record of youth. In order to help in saving our planet and brighten the future of younger generations, we must all (NGOs, citizens, communities, elected officials, companies) become aware of the stakes of resources, of our responsibilities to act by changing our way of producing and consuming, by questioning our lifestyles based on overconsumption, by starting to adopt a "zero waste" approach by refusing and reducing packaging, by reusing, recycling and composting. To do so, it is important to make young people adopt a different approach to consumption by thinking about waste production. Following these observations, the European partners of the project wish to respond to the crying needs of a lack of awareness, knowledge, tools, good practices, advocacy, dialogue between community, civil society, public and private actors to move to zero waste and become multipliers by acting with young people. The main objective of the seminar is to exchange practices and develop the key and transversal competences (knowledge, attitudes and skills) of 45 youth workers (disadvantaged, migrants and refugees). The purpose is setting up non-formal education youth initiatives and projects related to zero waste, improving personal and professional development, participation to the society by promoting the development of skills and knowledge, professional development, participation in society as active and responsible citizens, promoting employability of young people and alternatives to single-use products which are responsible for considerable amounts of waste and unreasonable consumption of natural resources. The specific objectives and the pedagogical path of the project are structured as follows: Stimulate the understanding of the notions of sustainable development, zero waste, circular economy, global warming and carbon emissions, ecological footprint, green entrepreneurship, eco-citizenship, disadvantaged youth, employability, innovation, start-up; extend the life span of objects, compost and sort bio-waste, reduce disposable... - Identify and understand the contexts and needs of youth workers in the theme of waste management and its challenges of sustainable development and innovation, generator of employment and experiences for young JAMO, including migrants and refugees; - Share and exchange experiences, solutions and good practices and change our view on waste management facilitating and improving the socio-educational and professional inclusion of disadvantaged youth; - Multiply the synergies between different actors and stakeholders (youth, civil society, local authorities, elected representatives, decision-makers, companies) allowing to identify the potential for innovation and employment in the zero waste approach; - Capitalize and create tangible tools with a multiplier effect for youth workers facilitating an innovative and creative ecological transition with an online guide "One year of challenges to go zero waste" with 1 challenge per month to be carried out during 1 year based on the good practices of the 27 member states of the European Union, and including young people in the job market by creating the tutorial "As a young person, I create from A to Z my start-up in zero waste"; - Develop new partnerships and an e-campaign "Towards zero waste" promoting the zero waste approach and recommendations by ensuring maximum dissemination to young people, NGOs, elected officials, decision-makers, public authorities and the general public (Chamber of consumers) and make zero waste an important part of public policies from local to European level.
