The idea of the project was born after mobility for youth workers Circular economy in youth work, after participants from the Netherlands, Bulgaria and Italy discovered common problems and had a desire to engage young people with environmental problems and promote Zero waste culture, since food loss and waste has indeed become a problem of great public importance. We found that in the EU approximately 20% of the total food produced each year is lost or wasted, costing us approximately 143 billion euros for the economy /FUSIONS,2016/, and the personal waste of each European per year is about 173 kilograms, while about 33 kg . million people in the EU cannot afford quality food every second day (Eurostat, 2018. Food waste is not only an ethical and economic problem, but also depletes the environment of its already limited natural resources. By increasing awareness of these issues among young people, we can contribute to achieving the Sustainable Development Goals towards a greener Europe and support the fight against climate change (food waste alone generates around 8% of global greenhouse gas emissions). It is the Zero Waste concept that is ethical, economical, efficient and visionary to guide people to change their lifestyles and practices to emulate sustainable natural cycles where all discarded materials are designed to become resources, for others to use. That is why we believed that every person should take a step forward through personal responsibility by understanding the problem and practicing the zero waste philosophy on a daily basis. Before the project, an online survey was also carried out on the topic of partner countries, which showed a lack of knowledge and awareness on topics such as the circular economy, the philosophy and practice of zero waste, the 3Rs system - recycle/reuse/reduce; specific practices of personal responsibility towards food waste and sustainability, composting Given the results of the survey, we concluded that there is a large gap in knowledge, awareness and competences among the youth of the participating organizations related to sustainability issues. These topics seem to be on the agenda and policy of the European Union, but it is still difficult to actively engage young people, so we decided to create this exchange as a learning platform for young people, using a participatory approach to young people, peer learning and experiential learning. Our aim was to raise awareness of sustainability issues and the zero waste philosophy and to stimulate sustainable behavior among young people. The main objectives of the exchange were: - raising awareness of environmental issues related to pollution, waste disposal, climate change and the connection to the daily choices of each individual -providing a deeper understanding of the concept of zero waste philosophy and promoting personal responsibility towards environmental sustainability; - understanding the role of young people in environmental sustainability and promoting social responsibility and activism
