The fourth issue of the DEMETER newsletter describes the dissemination workshops the project organized in order to present results, updates and project progresses. With the aim of boosting the project impacts and visibility, two dissemination workshops were organized in November 2018. The first one was held in the framework of Ecomondo, the leading fair of the green and circular economy (Rimini, Italy) by CiaoTech, the second took place in Leipzig (Germany) and it was organized by DBFZ. DEMETER provided a comprehensive overview on the achievements of the project to interested stakeholders and users coming from academia, industry and public levels.
