It focuses on understanding how internal capabilities and external knowledge sources influence sustainability outcomes across economic, environmental and social dimensions.<\/jats:p>\n <\/jats:sec>\n \n Design\/methodology\/approach<\/jats:title>\n The study used a sample of 978 SMEs from Kenya, South Africa and Nigeria. Structural equation modeling (SEM) is applied to explore the relationships between knowledge sharing, circular economy adoption and sustainability outcomes. Data were collected through surveys, and the analysis examines both the direct and mediating effects of internal knowledge sharing (IKS) and external knowledge sharing (EKS).<\/jats:p>\n <\/jats:sec>\n \n Findings<\/jats:title>\n The results show that both IKS and EKS significantly drive the adoption of circular economy practices, which in turn positively influence economic performance (EP), environmental sustainability (ES) and social sustainability (SS). IKS and EKS also act as mediators in these relationships. The study highlights the unique challenges SMEs face in Sub-Saharan Africa, including resource constraints and political stability, which impact the adoption process.<\/jats:p>\n <\/jats:sec>\n \n Practical implications<\/jats:title>\n Policymakers and SMEs can use these findings to create strategies that strengthen internal capabilities and foster external partnerships to overcome barriers and enhance sustainability practices in Sub-Saharan Africa. These insights can help improve the competitiveness and resilience of SMEs in the region.<\/jats:p>\n <\/jats:sec>\n \n Originality\/value<\/jats:title>\n This study contributes to the circular economy literature by addressing the underexplored context of Sub-Saharan Africa. It revises existing theoretical models by incorporating internal and external knowledge networks, offering a more context-specific framework for circular economy adoption in emerging economies.<\/jats:p>\n <\/jats:sec>","DOI":"10.1108\/jeim-03-2025-0188","type":"journal-article","created":{"date-parts":[[2025,6,27]],"date-time":"2025-06-27T04:15:29Z","timestamp":1750997729000},"page":"87-115","source":"Crossref","is-referenced-by-count":11,"title":["Leveraging knowledge sharing for circular economy practices in small and medium-sized enterprises (SMEs): a pathway to achieving SDGs in Sub-Saharan Africa"],"prefix":"10.1108","volume":"39","author":[{"given":"Jianhua","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Management, Zhengzhou University , ,","place":["Zhengzhou, China"]}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4082-4341","authenticated-orcid":true,"given":"Philip","family":"Adu Sarfo","sequence":"additional","affiliation":[{"name":"School of Management, Zhengzhou University , ,","place":["Zhengzhou, China"]}]},{"given":"Gideon","family":"Adjorlolo","sequence":"additional","affiliation":[{"name":"University of Electronic Science and Technology of China School of Management and Economics, , ,","place":["Chengdu, China"]}]},{"given":"Augustine","family":"Appiah","sequence":"additional","affiliation":[{"name":"School of Management, Zhengzhou University , ,","place":["Zhengzhou, China"]}]},{"given":"George","family":"Nyantakyi","sequence":"additional","affiliation":[{"name":"Zhongnan University of Economics and Law School of Accounting, , ,","place":["Wuhan, China"]}]},{"given":"Joshua Kojo","family":"Bonzo","sequence":"additional","affiliation":[{"name":"Taiyuan University of Technology School of Economics and Management, , ,","place":["Taiyuan, China"]}]},{"given":"Sajjad","family":"Alam","sequence":"additional","affiliation":[{"name":"School of Management, Zhengzhou University , ,","place":["Zhengzhou, China"]}]}],"member":"140","published-online":{"date-parts":[[2025,6,30]]},"reference":[{"issue":"4","key":"2026013100175245200_ref001","doi-asserted-by":"publisher","first-page":"405","DOI":"10.1080\/20421338.2019.1656428","article-title":"SMEs in sustainable development: their role in poverty reduction and employment generation in Sub-Saharan Africa","volume":"12","author":"Abisuga-Oyekunle","year":"2020","journal-title":"African Journal of Science, Technology, Innovation and Development"},{"issue":"6","key":"2026013100175245200_ref002","doi-asserted-by":"publisher","first-page":"1609","DOI":"10.1002\/sd.2109","article-title":"Environmental collaboration, sustainable innovation, and small and medium-sized enterprise growth in Sub-Saharan Africa: evidence from Ghana","volume":"28","author":"Adomako","year":"2020","journal-title":"Sustainable Development"},{"issue":"3","key":"2026013100175245200_ref003","doi-asserted-by":"publisher","first-page":"733","DOI":"10.1108\/JEIM-04-2021-424","article-title":"Determining sustainability key performance indicators for food loss reduction","volume":"34","author":"Al-Dalaeen","year":"2021","journal-title":"Journal of Enterprise Information Management"},{"issue":"6","key":"2026013100175245200_ref004","doi-asserted-by":"publisher","first-page":"1655","DOI":"10.1108\/BPMJ-10-2022-0515","article-title":"Knowledge management capability and organizational performance: a moderated mediation model of environmental dynamism and opportunity recognition","volume":"29","author":"AlMulhim","year":"2023","journal-title":"Business Process Management Journal"},{"issue":"9","key":"2026013100175245200_ref005","doi-asserted-by":"publisher","first-page":"1873","DOI":"10.1108\/PR-05-2020-0372","article-title":"Knowledge sharing, knowledge transfer and SMEs: evolution, antecedents, outcomes and directions","volume":"50","author":"Anand","year":"2021","journal-title":"Personnel Review"},{"key":"2026013100175245200_ref006","doi-asserted-by":"publisher","first-page":"210","DOI":"10.1016\/j.techfore.2017.09.017","article-title":"External knowledge sources, green innovation and performance","volume":"129","author":"Arfi","year":"2018","journal-title":"Technological Forecasting and Social Change"},{"key":"2026013100175245200_ref007","doi-asserted-by":"publisher","first-page":"142","DOI":"10.1016\/j.jclepro.2024.142307","article-title":"Organisational transformation toward circular economy in SMEs.
