Instead of disposing of this biomass waste, the team processes it into a plastic-like material through an innovative process involving molding and air-drying, resulting in a small, approximately 0.5 cm thick plate with a density of 1.23 g/cm³, comparable to the density of conventional printed circuit boards (PCBs). Using direct ink writing or a standard etching process and manual soldering, the researchers were able to deposit electronic components directly onto the fungal plates.
Are there use cases where it’s especially important for circuit boards to be compostable?
They’d be good for anything disposable that will be thrown into the trash
I guess the used vapes I find lying around have circuit boards in them
Yeah, but we could also ban vapes without replaceable batteries that cannot be charged.
There’s no reason for vapes to exist that are throwaway products.
Powerbanks can be charged. Vapes are just smaller powerbanks with a heating element.
I suppose it makes extracting the valuable/scarce materials easier when the circuit boards brick
