Vigilant Recycler

 is a perk in Fallout: New Vegas.

Effects
Waste not, want not. When you use Energy Weapons, you are more likely to recover drained ammunition. You also have more efficient recycling recipes available at the wasteland's Workbenches.

The efficient recycling recipes allow you to construct an energy weapon ammo out of three drained cells instead of four, and you are twice as likely to recover drained cells when you use Energy weapons.
