Although the concept of the circular economy as a term was first mentioned in 2015, when the "Action Plan for the circular economy" was adopted at the European level, it is still not possible to speak of a sufficient knowledge base in this area. The Action Plan (COM (2015) 614) can be seen as an initial strategic document that sets out a concrete and ambitious roadmap for implementing the Sustainable Development Agenda 2030. However, the European Green Agreement cannot be left out in this context either (COM(2019) 640). It is seen as a new growth strategy to transform the EU into a fair and prosperous society with a modern, competitive, resource-efficient economy, with net greenhouse gas emissions expected to be zero by 2050 and economic growth independent of resource use. A new EU circular economy action plan - Towards a cleaner and more competitive Europe was also adopted in 2020 (COM(2020) 98). The main priority areas are measures focusing on the value chains of key products electronics and ICT (information and communication technologies), batteries and vehicles, plastics, textiles, packaging, construction and buildings, food, water and nutrients measures covering all links in the value chain from production to consumption, repair and refurbishment, waste management up to the return of raw materials back to the economy and their use in the production cycle in the form of secondary raw materials. The transition to a circular economy also includes a revision of the European waste directives: on waste, on packaging and packaging waste, on landfills, on batteries and accumulators and used batteries and accumulators, and on waste electrical and electronic equipment. In order for all of this to be possible, it is necessary to know the amount of waste produced by individual sectors, which is also dealt with in our article. [ABSTRACT FROM AUTHOR]
