Estonian engineers found that 15-year-old smartphones, when hacked to work together as a single self-organized unit, can handle many such tasks with unexpected ease.

The approach is especially handy for IoT applications that need to crunch data at unusual or out-of-the-way locations.

Reusing old smartphones in this way could help reduce the cost of IoT projects but also tackle the ballooning problem of e-waste.

The open-source line, discontinued in 2016 , featured a modular design that was easy to take apart.

According to the World Health Organization , electronic waste is globally one of the fastest growing waste streams.

In 2022 , 62 million metric tons of old electronics have been disposed of around the world with only about 22 percent properly recycled.
