<p><?tk 4?>Understanding how technology adoption theories have been applied, extended, and integrated to explain e-waste technology uptake is critical for advancing both academic discourse and practical decision-making in the e-waste sector. Yet, existing scholarship remains conceptually dispersed, with prior reviews offering limited theoretical synthesis. Synthesising these diverse approaches is important for identifying common explanatory patterns, including the evolution of the factors and research gaps that can support cumulative knowledge development. This is the first scoping review to systematically map how technology adoption theories and frameworks have been utilised to explain e-waste technology adoption across the consumer and organisational levels. A total of nine peer-reviewed studies from Scopus and Google Scholar were identified that explicitly employ, extend, or combine established models. The findings reveal that behavioural theories such as TPB, TAM, and UTAUT predominantly explain technology adoption at the consumer level, whereas organisational studies primarily employ theories and frameworks such as DOI and TOE to examine organisational readiness, technological capability, and institutional pressures. However, the eligible theory-driven studies are conducted in China, India, Sri Lanka, and Bangladesh, with limited evidence from other national contexts. These settings differ substantially in institutional and technological conditions, which limit broad generalisation. The review contributes to theoretical understanding by organising dispersed theoretical applications, identifying underexplored constructs and contextual gaps, and outlining a research agenda for future studies in e-waste technology adoption. In practice, it provides a theory-informed foundation for policymakers and research and development teams seeking to support smart, circular e-waste technology transitions.</p>
