Author(s)
Philip Tanabe, Peter Key, Katy Chung, Emily Pisarski, Jessica Reiner, Alix Rodowa, Jason Magnuson, Marie DeLorenzo
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous and persistent environmental contaminants originating from many everyday products. Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are two PFAS that are commonly found at high

Decarbonizing the Economy: Circularizing Solar Photovoltaics

May 2, 2024
Author(s)
Nehika Mathur
Solar photovoltaics (PVs) are the fastest growing clean energy technology. As the first generation of solar PVs reach the end of their functional lives, it is becoming clear that unless strategies to manage discarded panels are implemented, we could be
