ENThis chapter aims to present key drivers, barriers, challenges, and opportunities for the Lithuanian manufacturing industry in a transition to the circular economy. It starts with an explanation of the importance of circular economy integration in manufacturing companies across value chains. The further focus is on the detailed research methodology by explaining the setting of the sample and the basis of the survey analysis. We then present the results of the original survey of Lithuanian manufacturing companies, as well as unifying drivers, barriers, challenges, and opportunities to encourage Lithuanian manufacturing companies to implement circular activities. Finally, we define a portfolio of relevant circular economy patterns in Lithuanian manufacturing companies and reveal the main differences across manufacturing companies, in terms of both biological and technical cycles.
