The widespread adoption of Internet of Things (IoT) devices has transformed numerous industries, yet it has also given rise to significant challenges regarding device longevity and electronic waste management. A key driver of premature IoT device decommissioning is the problem of software obsolescence and growing security vulnerabilities. As vendors provide software updates for limited periods, older IoT devices become increasingly vulnerable, compelling replacements even when hardware remains functional. This phenomenon leads to substantial electronic waste with hazardous materials impacting the environment. This paper proposes a comprehensive framework for secure and resilient IoT software updates to extend device lifespans and mitigate environmental impacts. The framework employs secure update delivery mechanisms, decouples critical security patches from feature updates, enables flexible policies and user control, and leverages edge computing and distributed architectures. By addressing software obsolescence and security issues, this framework reduces electronic waste, promotes a circular IoT economy, enhances energy efficiency, and fosters sustainability across the IoT ecosystem. Stakeholder recommendations are provided for IoT manufacturers, policymakers, and vice owners to drive adoption and realize the environmental benefits. Implementing this framework paves the way for a more sustainable and responsible IoT future by enabling the secure longevity of connected devices.
