Electronics are complex devices that are made from a variety of different materials, some of them being lead, nickel, and mercury. If not disposed of properly hazardous materials could leak into the environment causing possible risk to human health and/or the environment. The EPA (Environmental Protection Agency) is very concerned about ensuring the proper management of used electronics at their “end-of-life” stage, and has undertaken a huge task of increasing the collection and responsible recycling of used electronics. A great resource off of their site is www.Earth911.com. Please be mindful that the third party recycling agency you choose is a reputable one, that will dispose of your items properly.
