Sony Ericsson have recently released a new line of handsets, dubbed the GreenHeart range. The GreenHeart handsets are made from recyclable materials which is good for the environment. During the research conducted by Sony Ericsson, it was revealed that, touch screen handsets are actually worse for the environment than candybar handsets, such as the C901. Handsets which feature a touch screen are usually feature rich, which can drain the battery very quickly, making it difficult to use environment friendly batteries. Touch screens also rely on glass, where as candybar phones can use recycled plastics. The Xpera X1 features a 3 inch touch screen, while the upcoming X2, will feature a 3.5 inch display. Perhaps in the future, if Sony are to continue with touch screen handsets, then we may see recycled glass in the displays.
