Wood Waste to Green Tech: Biodegradable Circuit Boards Unveiled
Researchers led by Thomas Geiger are making waves in sustainable technology. They're developing biodegradable circuit boards using wood waste, a significant step away from traditional petroleum-based PCBs.
The team, collaborating with unnamed industry partners, is creating PCBs from lignocellulose, a waste product from wood processing. This material is processed into thin fibrils and bound with lignin to form the substrate.
The resulting boards are almost as resistant as conventional PCBs but are sensitive to water and high humidity. Geiger and his team are working to improve this resistance without compromising biodegradability. They've already created functioning devices like a computer mouse using this sustainable material.
The ultimate goal is to make electronic devices compostable at the end of their life cycle. Metallic and electronic components can still be recycled, making disposal less costly and challenging than traditional PCBs.
The research team, led by Thomas Geiger, is paving the way for greener electronics. By developing biodegradable PCBs from wood waste, they're addressing the environmental impact of electronic waste. With industry partners, they aim to produce more demonstration devices and explore further applications for this innovative material.
