Researchers from the Poznan University of Technology in Poland and the Linkoping University in Sweden have been whittling away at the possibilities of creating energy from wood waste. The key ingredient in this new technology is lignin, a chemical compound of waste produced in the paper-making process. Scientist are using the lignin as an insulator and polypyrrole as a conductor to create and hold an electric charge. Wood is of course a renewable resource, and it’s much more readily available than the chemicals used in traditional batteries. While the technology is still in research phases, we could see the use of wooden batteries in our lifetime as we continue to utilize our natural resources for renewable fuel and energy!
