Rechargeable battery stewardship organization Call2Recycle explained the rationale for EPR programs: "all companies that put batteries into the marketplace should pay for the recycling. But approximately 30% of batteries we collect are from ‘free riders’ – battery brands that are recycled through our program but are not financially contributing to Call2Recycle... We need tougher laws that require non-participating companies to join a formal program. We are advocating for state and provincial regulations that require manufacturers to recycle their batteries under the threat of penalties, including having their products blocked from being sold within the state or province."
