Small and medium-sized enterprises (SMEs) in the technology sector face unique sustainability challenges due to rapid technological advancement, resource-intensive operations, and growing environmental expectations from stakeholders. This study aims to develop an environmental sustainability business model with an emphasis on circular economy principles for technology-oriented SMEs. Drawing upon the concepts of sustainable business models and circular economy, a conceptual framework was developed and validated through expert evaluation using a Design Science Research approach. The proposed model integrates four key dimensions: organizational enablers, circular economy practices, environmental sustainability outcomes, and business performance outcomes. The findings indicate that effective implementation of circular economy practices contributes to waste reduction, resource efficiency, energy optimization, and carbon reduction while simultaneously enhancing innovation capability, competitive advantage, organizational resilience, and sustainable growth. The study provides both theoretical and practical contributions by offering an integrated framework that supports the transition of technology SMEs toward environmentally sustainable and economically viable business operations https://www.jise.ir/article_246087_0cd22b0c3ede085c770c6a4fa4848f6e.pdf
