Recycling

Recycler	Returns	Time
Recycler50% back	15 Gun Powder, 12 to 13 Metal Fragments	5s
Barrel recycler40% back	12 Gun Powder, 10 Metal Fragments	8s
Powered recycler75% back	22 to 23 Gun Powder, 18 to 19 Metal Fragments	4s

A range means the last unit is a coin flip rather than a guarantee: half the recipe rarely divides evenly, and the recycler rolls for the remainder.

Tech tree

On the workbench 2 tree, 9 unlocks in, reachable after Semi-Automatic Pistol.

No scrap price on the tree itself: every node ships with its cost overridden to -1 and the fallback is not recoverable from the files. The research table price above is a different number and that one is derivable.
