The sweet snack that is providing a solution to electronic waste
Zinc-based electronic circuit boards can be printed on paper, bioplastics and chocolate (University of Glasgow)
Engineers at the University of Glasgow have developed new biodegradable circuit boards to address the growing problem of electronic waste.
The innovative design involves printing electronic circuits onto biodegradable surfaces like paper, bioplastics, and even chocolate using zinc instead of traditional copper.
These environmentally-friendly circuit boards can be safely disposed of through ordinary soil composting, offering a 'circular electronics' solution.
The new boards perform comparably to conventional circuit boards and have been successfully tested in various devices, including LED counters and temperature sensors.
This breakthrough aims to significantly reduce the estimated 62 million tonnes of electronics discarded globally in 2024, with potential impacts for consumer electronics and IoT devices.
