With the increasing concerns about sustainability and environment risks, the problem of the recycling of such complex composite systems has been emerging in politics, industry, and academia. The issue is exacerbated by the increased use of FRPs in the automotive industry and by the expected decommissioning of airplanes and wind turbines amounting to thousands of metric tons of composite materials. Currently, the recycling of FRPs downcycles the entire composite to some form of reinforcement material (typically for cements) or degrades the polymer matrix to recover the fibers. Following the principles of sustainability, the reuse and recycling of the whole composite\u2014fiber and polymer\u2014should be promoted. In this review paper, we report on recent research works that achieve the recycling of both the fiber and matrix phase of FRP composites, with the polymer being either directly recovered or converted to value-added monomers and oligomers.<\/jats:p>","DOI":"10.3390\/polym13213817","type":"journal-article","created":{"date-parts":[[2021,11,4]],"date-time":"2021-11-04T22:25:54Z","timestamp":1636064754000},"page":"3817","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":57,"title":["Matrix and Filler Recycling of Carbon and Glass Fiber-Reinforced Polymer Composites: A Review"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4830-0374","authenticated-orcid":false,"given":"Roberto","family":"Scaffaro","sequence":"first","affiliation":[{"name":"Dipartimento di Ingegneria, Universit\u00e0 di Palermo, Viale delle Scienze, Ed. 6, 90128 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Di Bartolo","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria, Universit\u00e0 di Palermo, Viale delle Scienze, Ed. 6, 90128 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadka Tz.","family":"Dintcheva","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria, Universit\u00e0 di Palermo, Viale delle Scienze, Ed. 6, 90128 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Boudenne, A., Ibos, L., Candau, Y., and Thomas, S.
