Bio-Grinder

Turning tames into kibble

The Bio-Grinder is a powered structure in ARK: Survival Ascended that breaks tamed creatures down into kibble. Its description: "Walk Tamed Creatures onto this while active to grind them into Kibble. Requires Power to activate." The ARK Wiki files it under the Bob's Tall Tales DLC and says it was released alongside Extinction, having been introduced in the Wasteland War DLC.

Unlocking and building it

The engram unlocks at level 85 for 50 engram points, with the Industrial Grinder as its prerequisite. The grinder is made in a Fabricator in 5 seconds from:

• 800 Metal Ingot or Scrap Metal Ingot
• 440 Cementing Paste or Achatina Paste
• 240 Polymer, Organic Polymer or Corrupted Nodule
• 60 Electronics
• 40 Crystal or Primal Crystal

As an item it weighs 4 and stacks to 5, so a full stack weighs 20. Our records count 4 loot crates that can contain it: the Hard and Legendary Orbital crates on Astraeos and on Extinction.

How the grinding works

• What it accepts: only tames from your own tribe. Wild creatures and other tribes' tames are left alone, creatures that are too large are not ground, and the wiki names Gachas, Armadoggos and Veilwyns among the exceptions.
• What comes out: the grinder harvests the corpse a little less efficiently than a Chainsaw would and adds kibble on top. Kibble quality follows the size of the species' egg, or an equivalent based on body size for creatures that give live birth, and the amount depends on the creature's level.
• Babies: fully grown creatures give kibble reliably, while babies only rarely do; the wiki says the exact chance is unknown.
• Saddles and inventories: anything a ground creature carries, its saddle included, ends up in a bag in the grinder's corner. You can spot that chute by its red light and the smoke coming out of the top.

Which kibble a creature yields

The ARK Wiki sorts creatures by the kibble they give when ground. A few examples from each group:

• Basic Kibble: Dodo, Parasaur, Phiomia
• Simple Kibble: Raptor, Triceratops, Pteranodon
• Regular Kibble: Stegosaurus, Sabertooth, Ankylosaurus
• Superior Kibble: Argentavis, Allosaurus, Mammoth
• Exceptional Kibble: Rex, Quetzal, Giganotosaurus
• Extraordinary Kibble: Phoenix, Rock Elemental, Liopleurodon
