Instead of filling landfills with electronic waste, researchers have created electronics that simply disappear when submerged in hot water.
Researchers from the National Physical Laboratory (NPL) in the UK have invented a circuit board that dissolves when placed into hot water. So instead of filling landfills with the electronic waste, the circuit board can be completely dissolved and reusable parts like capacitors can then be salvaged.
Inhabitat notes that usually only around 2% of a circuit board’s components can be gathered when it is disassembled, but this new method allows 90% to be recovered. The NPL’s board has polymeric layers, which can withstand general moisture and thermal heat, but when it is submerged in the water the polymers are released causing it to dissolve.
