Researchers propose repurposing discarded smartphones as 'junkyard computers' to extend device lifetimes and reduce carbon emissions from manufacturing. The study demonstrates that even older smartphones can handle modern cloud microservices and introduces a new metric, Computational Carbon Intensity, to evaluate carbon efficiency. A prototype cloudlet using reused Pixel 3A phones shows potential for sustainable distributed computing.
Background
Smartphones are frequently discarded after short lifespans despite having capable hardware, contributing to electronic waste and unnecessary carbon emissions from new device manufacturing. Distributed computing systems often overlook the environmental impact of hardware production in favor of runtime efficiency metrics.
