hough the lead plates in a ULAB have been exhausted, this does not mean that the lead within the battery cannot be reused. In fact, most new lead-acid batteries contain up to 80% recycled, purified lead - making recycled lead a very valuable material.48 Because of the success of recycled lead, the market for extracting and reselling used lead has grown substantially, particularly in low- and middle-income countries. Though high-income countries have developed safe and effective processes for the reclamation of lead from ULABs, the recycling process that occurs throughout much of the rest of the world is far less developed and regulated.
