Some day soon your obsolete gadgets could be as compostable as banana peels and spent coffee grounds. Researchers from the Young Investigator Network at Karlsruhe Institute for Technology (KIT) in Germany are developing printed electronics from natural and compostable materials that could help make a dent in the millions of tons of electronic waste piling up worldwide each year.
Plastic carrier bags are typically petroleum-based, take a long time to decompose and are often imported from distant countries. They're also tricky to carry when cycling. The new PaperJohn tackles all of these issues. It's a backpack made of biodegradable, 100 percent recycled paper.
As electronic devices are becoming outdated at an increasingly fast pace, e-waste continues to be a huge problem.
That's why scientists from the University of Wisconsin-Madison have
started producing "wooden" semiconductor chips that could almost
entirely biodegrade once left in a landfill. As an added bonus, the
chips are also flexible, making them prime candidates for use in
