Passive PBI requires some unusual items:
- Chrome Dust: You can either use the Ruby Bee though ruby juice or Chrome Bee
- Zinc Dust: Your only option for passive zinc is the Zinc Bee and galvania, but the recipe time and uum cost isn't worth it.
- Copper Dust: You can use either the Copper Bee or one of the many IC2 copper crops: Coppon, Cyprium, and Copper Oreberry
- Saltpeter: You can use either the Salt Bee or Salty Root to produce it.
As for the fluids:
- Ammonia: It's slow to produce, having multiple LCRs making it passively at all times is probably a good idea
- Nitric Acid: The reason why you need so much ammonia for this line.
- Phthalic Acid: If you plan on doing bees, you'll want this passive anyway, It's included in this chart in case you don't have it setup already.
- Sulfuric Acid: It's just sulfur and oxygen, if you have Nether Stonelilies or Sulfur Bee already setup, you'll be fine on sulfur.
- Oxygen: You need quite a lot of it thanks to phthalic acid. Sweed and Sugar Beets are a good way to produce sugar which turns into oxygen.
Recycling the hydrochloric acid is optional if you are pumping chlorobenzene from mars or if you can afford to waste a bit of chlorine and hydrogen.
