Smartphones Find New Role as Recycled Data centers
Global smartphone production exceeds 1.2 billion units annually, straining resources and releasing significant CO2. Consumers typically replace phones every two to three years, leading to increased e-waste, with devices frequently enough ending up in landfills.
Researchers at the University of Tartu’s Institute of Computer Science and the Institute of Technology are exploring choice solutions. Huber Flores, associate professor of pervasive computing, said innovation involves “re-imagining its role in shaping the future.” The team demonstrated that smartphones can be repurposed into data centers for processing and storing data at a cost of about 8 euros per device.
These small data centers could collect real-time data in urban settings, such as bus stops, to optimize public transportation.
The team removed batteries and used external power sources to prevent chemical leaks. They connected four phones, housed them in 3D-printed cases, and created a working prototype to promote enduring practices.
The prototype was tested underwater to monitor marine life,automating species counting that typically requires scuba divers.
The team’s findings suggest that outdated technology can be repurposed with minimal resources, contributing to sustainable digital solutions.
“Sustainability is not just about preserving the future — it’s about reimagining the present, where yesterday’s devices become tomorrow’s opportunities,” said Ulrich Norbisrath, associate professor of software engineering.
What’s next
The researchers plan to explore further applications for repurposed smartphones, focusing on expanding the role of these devices in environmental monitoring and data collection.
