A plastic bridge sounds like something that belongs in Legoland. But in New Jersey, a 56-foot-long bridge crafted from recycled soda bottles, coffee cups and similar refuse has been carrying traffic for more than a year. Although the scientists who invented the plastic material used to build the one-lane bridge admitted that their technology is not yet ready for use on heavily traveled bridge, such as those in the interstate highway system, they say plastic has quickly gone beyond their expectations as a bridge-building material. Most notably, their plastic is already technically and economically competitive with wood. Building the plastic bridge was so easy that it took 11 days for three PhDs, one maintenance guy and a few helpers to do it. The price tag was $75,000—far less than the $350,000 a traditional wood bridge might have cost. And the plastic bridge has the added advantage of safely and creatively dealing with solid waste. Plastic is also safer for the environment. Wood used in construction is typically treated with chemicals that keep insects away, but many states have banned some commonly used treatments because of concerns that they contribute to environmental pollution. Plastic also needs less maintenance than wood, metal or concrete. Bugs have no interest in eating plastic beams, and plastic does not need to be painted.
