Factory

The factory is a structure in a minor dilapidated state. The entrance is blocked off by steel scaffolds. It is actually one of the least damaged structures in the game.

Where to find
It is pretty common and can generate in any biome.

Dangers
Don't fall into the lava. Other than that, it is completely safe.

Loot
There are 4 loot chests and lots of usable machines.

Chests
The three chests next to the Basic Factories contain common loot.

The other chest, located under the lava in the chimney, contains weapon-related loot.

Blocks
It contains two working Basic Factories and one broken factory

6 RTG Furnaces,

6 Breeding Reactors,

6 Blast Furnaces,

a bunch of Reinforced Glowstone, and

2 Iron Blocks.

Refurbishing
Other than the one titanium factory, the factory is completely undamaged, making refurbishing extremely easy. Finding one of these early on is quite good as you have: You could also mine all of the blocks and machines and put them into your own mud hut of a house like a savage barbarian.
 * A large and sturdy shelter
 * Plenty of machines that would otherwise take lots of time and resources to build
 * Especially the nuclear-science related ones
