Key Findings

  • 01The U.S. consumed 354 thousand tonnes (kt) of processed graphite in 2018, with a significant portion being imported.
  • 02Batteries accounted for a relatively small but growing percentage of graphite consumption (10% natural, 5% synthetic).
  • 03A substantial amount of graphite (78%) dissipated into the environment, and 22% reached waste stages, with a majority being landfilled.
  • 04Recycling and alternative production methods (e.g., from lignin) could significantly improve the graphite supply chain.
