Despite basalt-based Enhanced Rock Weathering (ERW) showing promise in croplands, identifying alternative application sites is crucial for scaling carbon dioxide removal (CDR) and maximizing co-benefits. This study investigated acid mine drainage (AMD) systems as potential ERW sites, emphasizing the use of mining waste rock as reactive material.
