What next?

 Boffins have managed to make a biodegradable chip, the computer kind.  They say it's make from wood, and will lead to a biodegradable mobile phone.
 Now I'm sure it's very clever and techie, but theres a small flaw in their otherwise brilliant plan... The chip in a phone is about half the size of a postage stamp, while the rest of phone (now the size of a WW2 frigate) is made from plastic, glass, lithium and God knows what else.  It's no good having the chip biodegradable if the rest of the phone isn't.... And frankly I really can't see an IPhone 9 made of wood can you?
