Turning those old electronic circuit boards into new park benches
Environmental Science & Technology
Scientists in China have developed a new recycling method that could transform yesterday's computer into tomorrow's park bench. Their study, which focuses on decreasing environmental pollution through resource preservation, reuses fibers and resins of waste printed circuit boards (PCBs) that were thought worthless to produce a variety of high-strength materials. It is in the July 15 issue of Environmental Science & Technology.
Zhenming Xu and colleagues point out that as more electrical and electronic equipment has become obsolete, the issue of electronic-waste removal has intensified. PCBs account for about 3 percent by weight of all electronic waste, Xu says. Although metals from the circuit boards, such as copper and aluminum, are recycled, landfill disposal has been the primary method for treating their nonmetallic materials, which have been difficult to recycle, the paper says.
In the study, the researchers
