Furthermore, the production of such devices leads to increased consumption of natural resources and produces a multitude of toxic and hazardous substances, which are normally not treated properly. One of the approaches that may be adopted to reduce such problems relies on the circularization of the current linear model, commonly adopted in the Electric and Electronic Equipment (EEE) value chain. This includes recovering End-of-Life products and reintroducing their parts, components, or raw materials into the value chain (e.g., semiconductors, circuit boards, raw metals, etc.), contributing to a more sustainable value chain. In this article, we present a state-of-the-art review that focuses on approaches and solutions for EEE value chain traceability and analyze the technologies that may be beneficial for promoting and implementing the Circular Economy model in this value chain.<\/jats:p>","DOI":"10.3390\/su15054574","type":"journal-article","created":{"date-parts":[[2023,3,6]],"date-time":"2023-03-06T03:22:05Z","timestamp":1678072925000},"page":"4574","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["A Review on Adopting Blockchain and IoT Technologies for Fostering the Circular Economy in the Electrical and Electronic Equipment Value Chain"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-2257-176X","authenticated-orcid":false,"given":"Leonardo","family":"Fernandes","sequence":"first","affiliation":[{"name":"IPVC\u2014Instituto Polit\u00e9cnico de Viana do Castelo, 4900-347 Viana do Castelo, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3883-1160","authenticated-orcid":false,"given":"Ant\u00f3nio Miguel","family":"Rosado da Cruz","sequence":"additional","affiliation":[{"name":"IPVC\u2014Instituto Polit\u00e9cnico de Viana do Castelo, 4900-347 Viana do Castelo, Portugal"},{"name":"Algoritmi Research Centre, Escola de Engenharia, Universidade do Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6426-9939","authenticated-orcid":false,"given":"Estrela Ferreira","family":"Cruz","sequence":"additional","affiliation":[{"name":"IPVC\u2014Instituto Polit\u00e9cnico de Viana do Castelo, 4900-347 Viana do Castelo, Portugal"},{"name":"Algoritmi Research Centre, Escola de Engenharia, Universidade do Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6944-7757","authenticated-orcid":false,"given":"S\u00e9rgio Ivan","family":"Lopes","sequence":"additional","affiliation":[{"name":"IPVC\u2014Instituto Polit\u00e9cnico de Viana do Castelo, 4900-347 Viana do Castelo, Portugal"},{"name":"IT\u2014Instituto de Telecomunica\u00e7\u00f5es, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"100507","DOI":"10.1016\/j.envc.2022.100507","article-title":"Electronic waste: A critical assessment on the unimaginable growing pollutant, legislations and environmental impacts","volume":"7","author":"Rajesh","year":"2022","journal-title":"Environ.
