The U.S. Postal Service launched a pilot program that allows customers to recycle small electronics and ink-jet cartridges by mailing them free of charge. The “Mail Back” program makes it easier for customers to discard used or obsolete small electronics in an environmentally responsible way. Customers can now find free envelopes in 1,500 post offices. The envelopes can be used to mail back PDAs, Blackberries, digital cameras, iPods and MP3 players without having to pay postage.
Postage is paid by Clover Technologies Group, a company that recycles, remanufactures and re-markets ink-jet cartridges, laser cartridges and small electronics. If the electronic item or cartridge cannot be refurbished and resold, its components are reused to refurbish other items or the parts are broken down further and the materials are recycled. Clover has a “zero waste to landfill” policy, which means it does everything it can to avoid contributing any materials to landfills.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
