We love our computer chips, but we also love throwing them away. Once our phones get old, we toss them, and the same goes for many other electronic devices. Computer chips are expensive waste, and many chips contain toxic materials and can cause pollution for the environment. Researchers at the University of Wisconsin have now developed a chip made mostly from wood pulp, and it works just as well as the ones made from materials like silicon. The biodegradable chips are almost ready to go on the market.
