Composites can offer superior properties and versatility but raise environmental concerns due to disposal challenges, even when made from bio-based materials. Hence, in this study, cork/PLA composites were recycled using dissolution–precipitation principles. First, virgin cork PLA extruded produce bio-composites which then dichloromethane separate the biomass filler biopolymer matrix. It was found that 80.9% ± 2.4 of 85.9% 5.9 successfully recovered, with recovered materials retaining same chemical structure as counterparts. The maintained its honeycomb after extrusion recycling, indicating resistance process. As expected, adding reduced composite’s mechanical performance, showed similar PLA. Both composite filaments displayed glass transition (Tg) cold crystallization (Tcrist) temperatures, presented slightly lower values, likely some degradation. Despite this, all exhibited thermal stability their Cork is primarily used production stoppers, and, hence, recycling efforts mainly focus on reusing stoppers rather than composites. Therefore, process proposed separated composites, maintaining comparable properties, highlighting potential for improving eco-efficiency
