Elephantech wants to create circuit boards that are kinder to the environment

Printed circuit boards (PCB), which perform essential functions in electronic devices, including displays and sensors, need a lot of energy to create. Moreover, traditional PCB manufacturing processes generate large amounts of liquid waste and high carbon emissions.
Still, there are more environmentally friendly ways of producing PCBs, including additive manufacturing processes that use inkjet and laser printing, while fully biodegradable PCBs are also on the horizon.
To get its slice of $90 billion PCB manufacturing pie, Tokyo-based startup Elephantech has developed an eco-friendly PCB called
