Printer giant Epson has developed an in-office paper recycling machine. Called the PaperLab, you put waste paper in, and then new, bright white printer paper comes out. Epson says this process is more efficient than sending paper to an off-site recycling plant, and it's also much more secure: the PaperLab, which breaks paper down into its constituent fibres before building them back up into new sheets, is one of the most secure paper shredders that money can buy.
