reprocess

The Greenpeace environment group said Sunday that France was sending reprocessed uranium to Russia for treatment so it can be reused, despite the Kremlin's war in Ukraine.

And so its ability to enrich or reprocess uranium is limited by the US as it is entirely dependent on imports.

Seoul had secured "support for expanding our authority over uranium enrichment and spent-fuel reprocessing", he said.

A nuclear agreement between the U.S. and South Korea, revised in 2015, bars Seoul from enriching uranium and reprocessing spent nuclear fuel without Washington’s consent, due to concerns of Seoul building its own nuclear program.

The much bigger trade is done in used cooking oil—or UCO—the leftover cooking oil that’s collected, filtered, and reprocessed to become a valuable industrial feedstock, particularly for biofuels.
