Tail piece

Intrigued by the structure and composition of this washed-up lobster tail I wondered if there was any use such debris could be put to. (Imagine the quantities of crab and lobster shells that must be discarded every single day.)
 Yes!  Research is currently being done on turning crustacean shells, composed of chitin and calcium, into a form of biodegradable plastic. They are also being used to make golf balls, tiles and table tops, plant pots and packaging.*
(The seaweed on the right itself looks remarkably similar to plastic bubble-wrap.)
