HP Uses Leftover Plastic Bottles for Its Ink Cartridges
HP has found a use for leftover plastic bottles. When we return our used HP (Hewlett-Packard) print cartridges, they “undergo a multi-phase recycling process that reduces them to raw materials such as plastics and metals.” The plastic from the inkjet cartridges gets mixed with recycled bottle resin and other binders to create brand new ink cartridges according to an article in Environmental News Service. They are not remanufactured. Other cartridge suppliers have yet to do this. The amount of recycled content varies from 70 to 100 percent, while the finished product remains at HP’s highest standard.
That’s a pretty good solution for some of our leftover plastic problems considering mixing plastics usually diminishes the strength and durability of a finished product. There are 10,000 different types of plastics, and many are not compatible together. If you haven’t noticed, most recyclable bottles are stamped with numbers. These numbers are to group the different plastic materials together when reprocessing.
But new research just might change things in the future. HP has discovered a way, and according to an article by Michigan Molecular Institute, “researchers from Eastman Kodak, Eastman Chemical, and the University of Florida (UF) accomplished that goal by establishing the fundamentals of compatibilization of multiphase polymer blends.” Researchers found effective methods to compatibilize comingled-plastic waste.” In other words they’ve found a way to mix some of the normally incompatible leftover plastic we toss to make new plastic.
Sharp has developed “a new technology to blend plant-based plastic that uses corn as the raw material, and waste plastic recovered from scrapped consumer electronics” according to an article on Physorg.com. Now this is real news because Sharp is getting away from petroleum based plastics, which is the common raw material for most plastic. I don’t think corn should take a hit again, because of its overuse by the ethanol industry, but who knows, corn today, rutabaga tomorrow as a raw material for plastic.
With new technology coming out all the time relative to plastics, hopefully we will greatly reduce the environmental impact our leftover plastic products produce. Next on the list, we need to see plastic that easily strips away in one zip from the cloth part of those dirty disposable diapers that get tossed. Anybody got any ideas about that?
