Spent primary alkaline batteries present an unused source of 553,500 tons of secondary metals in Europe and the US in 2009. While battery recycling programs exist, current processes are not profitable, so industry growth is difficult. A novel mechanical separation process was developed to recycle alkaline batteries at lower cost than current methods. Using a process-based cost model, the cost was determined to be $1286 per metric ton with revenue of $382 per metric ton, so supplemental funding is needed.
