    Discarded electronic devices, such as cellphones, are a fast-growing source of waste. One way to mitigate the problem could be to use components that are made with renewable resources and that are easy to dispose of responsibly. Now, researchers reporting in ACS Applied Materials & Interfaces have created a prototype circuit board that is made of a sheet paper with fully integrated electrical components, and that can be burned or left to degrade.

    Most small electronic devices contain circuit boards that are made from glass fibers, resins and metal wiring...
