Sandustry burnt residue is the fork in the chain: dropped 25 blocks through a Kinetic Press, each pixel splits into exactly one Gold and one Seed.
Burnt Residue is the surviving quarter of burned Residue, and it is where the production chain forks. Dropped through a Kinetic Press from a height of at least 25 blocks, each pixel splits into one Gold and one Seed - the Gold pays for research, the Seed feeds the flower loop that eventually produces Amethelis and Florin. The 25-block drop requirement is a real layout constraint, so it is worth planning the vertical shaft before building the rest.
How to get Burnt Residue
There is a single route to Burnt Residue — ignite residue — so it is the step to size first when a line running on Burnt Residue starves.
| Method | From | Machine | Notes |
|---|---|---|---|
| Ignite Residue | Residue | Flamethrower / Rocket Launcher (napalm) / Pyro Dispenser / Lava in a Filter | Only ~25% of Residue survives; the rest burns away. |
What Burnt Residue is used for
Burnt Residue is an input to Gold and Seed, which is why it usually pays to buffer it rather than consume it the moment it appears.
| Produces | Machine or process | Notes |
|---|---|---|
| Gold | Kinetic Press | 1 per Burnt Residue. |
| Seed | Kinetic Press | 1 per Burnt Residue. |
Conversions
Ratios are documented for Burnt Residue, so you can size the line arithmetically instead of by trial and error.
| Input | Output | Process | Ratio |
|---|---|---|---|
| 1 Burnt Residue | 1 Gold + 1 Seed | Kinetic Press | 1:1:1 |
- 1 Gold + 1 Seed: Must be dropped through the Press from at least 25 blocks height.

FAQ
How do you get burnt residue in Sandustry?
Ignite Residue. A Flamethrower, Pyro Dispenser, Rocket Launcher napalm, or Lava held in a Filter all work; roughly a quarter of the Residue survives as Burnt Residue.
What is burnt residue used for in Sandustry?
A Kinetic Press splits each pixel into one Gold and one Seed. The Gold funds research and the Seed feeds the Wet Seed and Flower loop toward Amethelis and Florin.
Why is my Kinetic Press not working in Sandustry?
The Press needs momentum. Burnt Residue must fall through it from a height of at least 25 blocks, so plan a vertical shaft before laying out the rest of the factory.
How much gold does burnt residue give in Sandustry?
Exactly one Gold per Burnt Residue pixel, plus one Seed. The ratio is fixed, unlike the probabilistic Gold roll on the Shaker.
Can burnt residue be burned again in Sandustry?
No. Burnt Residue is not burnable; the Kinetic Press is its only documented processing route.
