Bacteria recycling lets you sacrifice unneeded Evolved Bacteria to obtain a random reward.
It is unlocked after destroying the 9th planet - Xutrutis.
Upon recycling a Bacteria, 9 to 25 cards appear on the screen.
When a card is selected, it flips over, revealing the reward. After the first reward is received, the player can select up to one additional card from the remaining set by paying 5
The recycling rewards are divided into four tiers with each tier consisting of up to seven different rewards. The possible reward tiers and the number of cards displayed are determined by the bacteria value coefficient (BVC). The recycling rewards in events can be different from the regular game.
Bacteria Recycling is the only Research Lab that doesn't directly require Scientists. It was first added to the game with version 1.3.0.
