Dust Retrieval is a Sheredyn-specific technology on the Diplomacy and Trading technology tree with a research cost of 130 
. It unlocks an Empire Improvement, requires research in Xenology or in Soil Xenobiology, and allows no further research.
"Military and honorable, the Sheredyn are aware that money is one of the ultimate decision makers. Dust retrieval systems were therefore developed to help cull free-floating Dust from areas that they colonize."

"When a battle has ended, Dust is often left behind in the form of actual Dust particles or salvageable goods. This application of Dust retrieval technology allows the Sheredyn to convert the debris of a space battle into currency."
