LEDs are hazardous waste
Light-emitting diodes (LEDs) should be classified as hazardous waste according to a study in the US. LEDs are advertised as environmentally friendly because they are energy efficient. But acid tests that mimic the chemical conditions encountered in landfill registered high levels of copper, lead, nickel and silver, which exceed California standards for hazardous waste. See Environ. Sci. Technol. (DOI: 10.1021/es101052q).
Larger role for science
The final report of the presidential oil spill commission in the US, which investigated the Deepwater Horizon oil spill (see Chemistry World, November 2010, p14), calls for more science to better protect the environment. Among the commission’s recommendations was an independent agency that would have a large science component, incorporating a Leasing and Environmental Science Office that would voice any future environmental concerns.
