There’s not much you can do with paper after you’ve written (or printed) both sides of it. You could use it to wrap stuff up you intend to store or throw away, but that’s about it. But if the LiteOn pencil maker ever gets made, then you can actually use it to make pencils.
It’s a concept that winds up the otherwise useless paper so tight that it forms the body of a pencil. Just feed spare paper it into the machine, wait a while, and voila! You’ve got a brand-spankin’ new customized pencil, ready for you to use.
Of course, the lead will be brand new, but I think that’s a pretty easy material to source and feed into the machine. Though there’s no plan for how to add an eraser to the pencils it cranks out.
The LiteOn pencil maker was designed by Chengzhu Ruan, Yuanyuan Liu, Xinwei Yuan and Chao Chen, and is only a concept at this point.
