This term doesn’t refer to all the spam filling your email box, though those messages do waste plenty of time. E-waste is actually the millions of tons of electronic products, computers, cell phones, and the like that enter the waste stream worldwide each year. As newer, better, cooler gadgets come on the market, the piles of e-waste grow ever higher. Aside from their contribution to landfills, many electronic devices contain hazardous materials, such as mercury; many also contain valuable, reusable materials that can be recycled. There are some simple ways to limit e-waste: Buy quality products that can be upgraded instead of replaced; donate old equipment (to a school for instance); and seek out recycling programs when you’re ready to dispose of an item. Also called electronic waste.
