DescriptionThis bibliographic collection contains the included Scopus records used for a bibliometric analysis of research at the intersection of circular economy, digital technologies, data integration, and decision support. The collection is provided in BibTeX (.bib) format and contains 2,924 records. The initial screened set comprised 4,731 records, of which 1,807 were excluded during automated screening and 2,924 were retained in the final bibliographic collection. Although the underlying Scopus query covered the 2015–2025 period, the included collection spans 2016–2025 because no 2015 records remained after screening.

Records were evaluated using dictionary-based signals related to circular economy, digital technologies, decision support, data integration and decision context. Records without a circular economy signal were excluded. Records with a strong circular economy anchor in the title or keywords were retained when paired with decision-support, data-integration, or digital-technology signals in combination with decision-context evidence. Records with only an abstract-level circular economy signal were retained only under stricter conditions. All records that did not meet the inclusion rules at the screening stage were treated as excluded. Eligibility criteriaEligible records were English-language journal articles and reviews within the 2015–2025 query window, with abstracts required. The collection is intended to support transparency, reproducibility, and reuse in bibliometric and review-based research. FundingThe research was funded by a grant from the state budget of Ukraine "Fundamentals of Sustainable and Inclusive Regional Spatial Development for Post-War Reconstruction in the Context of Digital Transformation" (# 0125U001620, 2025-2027)
