However, this nominal recycling rate does not reflect the actual material flow of titanium and its alloys. Because titanium is an expensive metal with a price above US$10/kg, recycling is well established in the smelting process for the primary metal (titanium sponge) and the machining industry for components.

Titanium is made by a batch process. In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something. With titanium, however, you make it one batch at a time.
