Q&A: Making Earth-friendly electronics

April 21, 2022 The very components that make electronics fast and easy to use also make their disposal an environmental nightmare. Components of smartphones, computers and even kitchen appliances contain heavy metals and other compounds that are toxic to us…

The biodegradable battery

The number of data-transmitting microdevices, for instance in packaging and transport logistics, will increase sharply in the coming years. All these devices need energy, but the amount of batteries would have a major impact on the environment. Empa researchers have developed a biodegradable mini-capacitor that can solve the problem. It consists of carbon, cellulose, glycerin and table salt. And it works reliably.

Making cleaner, greener plastics from waste fish parts

Derived from crude oil, toxic to synthesize, and slow to degrade, polyurethanes are not environmentally friendly. Today, researchers discuss a safer, biodegradable alternative derived from fish waste that would otherwise likely be discarded. They will present their results at ACS Spring 2021.
