On the fringes of green technology

On paper, PolyTurf has a lot going for it. It starts out with a nearly worthless product (recycled tires) turns it into an easy-to-maintain version of something nearly every homeowner has or wants (a lawn) and lets them cut down on water, a dwindling resource, particularly in the fast-growing sunbelt. They can even give you different types of lawn, from Royal No Fill (Straight 2-inch pile height, 52-ounce polyethylene thiolon synthetic turf) to Golf Green. It can even be made with an antibacterial layer.
