An article in the New York Times (Dec 9, 2011) describes the EPA regulation of lead recycling from the 97 % of batteries recycled, the consequent cost impact of these regulations of $ 20 million in capital investments to comply, and the increased exports of used batteries to Mexico – an increase from 6 % (of total volume) in 2007 to 20 % in 2011.  The reason, poor enforcement of pollution laws in Mexico permits 20 times the amount of lead to be released to the environment.  EPA laws govern US plants but permit unlimited exports.  Should battery manufacturers be held responsible for the associated recycling of used batteries ? Should the EPA require documentation of safe recycling of used batteries shipped to Mexico ? Should exports of US used batteries require a certification of compliance of US pollution laws ?
