For years, Hewlett-Packard has encouraged its customers to recycle their ink cartridges, and it even pays the shipping costs for sending them back.
But now, HP is embarking on an even more ambitious recycling program. For starters, HP has already undertaken a program in which it uses a wide variety of recycled consumer goods to build scanners. Now, the company has a prototype of a biodegradable printer made out of corn.
"You can’t throw it in your backyard," said HP spokeswoman Lynelle Preston, adding that the prototype on display was a very early version of the printer. But "given the right conditions, it would disappear."
