If you've purchased a television in the past five years, chances are it is a flat screen with a liquid crystal display (LCD) or plasma. According to the Environmental Protection Agency, many consumers/business are now purchasing their second or third flat screen television and facing a decision of what to do with the old sets. There are significant differences in the material that makes up LCD and plasma TVs which can make recycling them tricky but also significantly important. The most important difference is the substantially higher amount of glass in plasma TVs while LCD TVs contain more types and higher amounts of plastic.
