In the first part, different combinations of SP (0, 5 and 10 wt%) and hardener (2, 5 and 10 wt%) were mixed with AESO resin, poured into a mould, cured and submitted to mechanical and physicochemical characterizations to identify the best conditions for the composite production. Virgin green composites with 10 wt% SP, 5 wt% hardener and 5 layers of jute fabric, capable of assuring 91 HA of hardness and 10.6 MPa of tensile strength, were fabricated. The second part describes the recycling process of the composites with acetone, an organic solvent recommended by the safety, health and environmental criteria, to breakdown the resin matrix and recover the jute fabric reinforcement and resin particles, which were then reused to fabricate a second-life composite. Although the hardness values of the second-life composite were smaller (4%) and the tensile strength varied with composition, the absorption of water was considerably reduced (in the range of 22 to 51%). This last result mitigates one of the green composite\u2019s limitations and fosters circular economy by assuring the applications of the second-life composite in the field of transportations, packing and furniture, among others.<\/jats:p>","DOI":"10.3390\/jmmp4030065","type":"journal-article","created":{"date-parts":[[2020,7,6]],"date-time":"2020-07-06T03:19:27Z","timestamp":1594005567000},"page":"65","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["On the Performance and Recyclability of a Green Composite Based on AESO Resin"],"prefix":"10.3390","volume":"4","author":[{"given":"Cl\u00e1udio P.","family":"Seabra","sequence":"first","affiliation":[{"name":"\u00c1rea Departamental de Engenharia Mec\u00e2nica, Instituto Superior de Engenharia de Lisboa, Instituto Polit\u00e9cnico de Lisboa, Rua Conselheiro Em\u00eddio Navarro, 1, 1959-007 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6133-7406","authenticated-orcid":false,"given":"Ana Catarina","family":"Sousa","sequence":"additional","affiliation":[{"name":"\u00c1rea Departamental de Engenharia Qu\u00edmica, Instituto Superior de Engenharia de Lisboa, Instituto Polit\u00e9cnico de Lisboa, Rua Conselheiro Em\u00eddio Navarro 1, 1959-007 Lisboa, Portugal"},{"name":"Centro de Qu\u00edmica Estrutural, Instituto Superior T\u00e9cnico, Avenida Rovisco Pais, 1049-001 Lisboa, Portugal"}]},{"given":"Ivo M.
