Techno-trash, or digital waste, includes cameras, CDs and tapes, MP3 players, laptops and storage devices, small electronic devices and rechargeable batteries. Greenward, in Cambridge, is encouraging the socially responsible disposal of these items by accepting them at its store. “E-waste is a huge environmental concern,” says owner Scott Walker. “Many toxic and valuable materials end up in landfills needlessly.”

Greenward is an eco-boutique for shoppers interested in sustainability and environmentally friendly products, accessories, gifts, gadgets and jewelry. Techno-trash items can be dropped off during regular store hours, from 11 a.m. to 6 p.m., Monday through Saturday (Thursday until 8 p.m.); and from noon to 5 p.m., Sunday.
