When people replace their home electronics, the old equipment is often still working, but difficult to sell. Second Rotation is attempting to create a marketplace for used electronics that will slow the pace of new additions to the landfill.

Digital cameras, gaming consoles, MP3 players and old cell phones are all items that the company might buy. It generally won’t pay for broken devices, but does offer a free recycling service.

The $4.4 million funding is Second Rotation’s first, led by Venrock, with some participation from angel investors. The company is based in Waltham, Mass.
