Sony, the Japanese multinational, presented a demonstration of an organic battery capable of generating energy from paper or cardboard at the Eco-Products fair in Tokyo. This way he was able to power a small fan. In the demonstration, a mass of paper or cardboard was mixed with water, after a chemical process, surprise, there was energy.

Its operation is relatively simple, the enzyme called cellulase breaks down paper or cardboard to form glucose. By combining them with oxygen and more enzymes, the material turns into electrons and hydrogen ions. These electrons are used by the battery to generate electricity.

The project is inspired by the mechanism used by white ants and termites to digest wood and convert it into energy.

Unlike traditional batteries, this biological cell does not use metals or other chemicals that are so harmful to the environment.

Hopefully Sony will do what is necessary so that this project can continue to be studied and that one day we can use our waste paper or cardboard as fuel for our electrical gadgets.
