On May 3, 2012, PRBA met with the U.S. DOT’s Pipeline and Hazardous Materials Safety Administration (PHMSA) to discuss regulatory challenges related to the transport of waste batteries in anticipation of a national primary battery collection program. In light of the vastly larger number of primary batteries replaced by consumers annually as compared to rechargeable batteries, establishment of this new program could have considerable impact on RBRC’s Call2Recycle® and similar used rechargeable battery recycling programs.
