The criticality of some materials, defined it the European Union Raw Materials Initiative is relevant for the industry of electrical and electronic equipment (EEE) from 2 perspectives: on the one hand the identified metals are necessary for the development of new technologies; on the onther hand – a potential risk exist to face the supply shortage of these materials, what could negatively impact EEE industry. The waste of EEE (WEEE) is one of the best sources for critical metals (CMs), as secondary raw materials, extraction. Therefore, this paper analyses the availability of CMs in the WEEE collected in Lithuania. The total amount of CMs contained in WEEE is estimated based on 2 methodologies and the amounts in 2020 are forecasted. It was evaluated how much CMs recovered from WEEE generated in Lithuania could cover the demand of European decarbonisation technologies in 2020. The estimated modest amounts of CMs, which is determined by a relatively small country in which WEEE management sytem is still in the development phase, shows the need for future research in order to analyse the best availabale technologies or other waste management alternatives in order to retrieve CMs.DOI: http://dx.doi.org/10.5755/j01.erem.72.2.16112

The identification of the main steps for the creation of a unified ecosystem from the institutional point of view and the framework for ecosystem design is presented and discussed. Based on the expertise and the knowledge gained during the time when the ELISE project had been implemented, a unified Kaunas city ecosystem is being designed using the Ecosystem Map method. As the review of the ELISE project reports helped to identify the main steps of each project partner in building ecosystems' networks, Kaunas city chose to create a co-Creation Hub (c-CH), which is the first step in developing an ecosystem management model. The main tasks of such a hub are listed, and should involve the preparation of a long-term action plan involving not only the coordination of the stakeholder meetings, organisation of seminars, the preparation of new materials, and methodology but also the development of a clear strategy for each stakeholder based on national economy and government and municipality policies. The role of the c-CH is to ensure the ease of cooperation and knowledge distribution among stakeholders within the city, public authorities, and the national government. This approach could become a fundamental background tool for the regional and/or city municipal and stakeholder-based creation and development of unified ecosystem development.
