This study presents a bibliometric analysis of research on circular biomaterials to map its intellectual structure, thematic evolution, citation impact, and collaboration patterns. Bibliographic data were retrieved from the Scopus database and analyzed using VOSviewer through keyword co-occurrence, overlay, and density visualizations, supported by citation, co-authorship, institutional, and country-level analyses. The results show that the field is organized around a circular economy pole that links biomaterials with sustainability, food waste, lignocellulosic biomass, biofuel, and 3D printing, and a biomedical pole that connects biomaterial with biocompatibility, tissue regeneration, and controlled animal studies. A dense agro-industrial waste and biopolymer cluster bridges both poles, confirming waste valorization as the main pathway through which biomaterials enter circular systems. The overlay analysis indicates a shift from early work on 3D printing and material characterization toward recent studies on tissue regeneration, lignocellulosic valorization, and agricultural applications. The most cited documents focus on additive manufacturing, agro-industrial biowaste valorization, and microbial bioconversion. Collaboration networks remain small and fragmented, consisting of single-team author and institutional clusters and limited international links centered on Nigeria and Malaysia. The study highlights circular biomaterials as a young and multidisciplinary field that requires stronger integration between circular economy principles, material engineering, and biomedical applications.
