The Placid process is a hydrometallurgical technique for recovering lead from spent battery pastes. The process, when used in combination with a pyrometallurgy process, has the potential to recover high-purity lead and offers significant environmental improvements.

Food pantries have traditionally focused on meeting emergency food needs. However, for many clients, food assistance is a long‐term need. The frequency with which long‐term clients visit food pantries varies; and in general, visiting frequency has been understudied because the focus has largely been on emergency, rather than long‐term, food assistance impacts. We leveraged a program innovation to identify the impact of visiting frequency on client outcomes. Using fixed‐effect models, we analyzed a panel of 1663 long‐term food pantry users observed monthly from 2017 to 2019. Within‐client increases in visiting frequency were associated with within‐in client improvements in food security and health.
