Astroneer is massive, colorful, and deceptively complex. At first glance, it feels like a relaxed space exploration sandbox. But once you dive into automation, resource chains, and interplanetary logistics, you quickly realize just how deep the systems go.
One of the most useful, and often overlooked, mechanics in Astroneer is salvaging scrap. Scrap allows you to convert unwanted debris and found objects into a tradable resource that can be exchanged for valuable materials. If you understand how salvaging works, you can turn abandoned wreckage into a steady supply of rare resources.
Let’s clean this up and walk through the process step by step.
What Is Scrap in Astroneer?
Scrap is a refined resource created by shredding debris, items, and certain crafted objects. Once processed, scrap becomes a solid resource block that can be used at the Trade Platform to exchange for other materials.
Instead of constantly mining for specific resources, you can salvage wreckage and trade scrap for exactly what you need. It’s an efficient way to manage excess items and turn junk into something valuable.
Step 1: Research a Shredder
Before you can salvage anything, you need to unlock a shredder in the Research Catalog using Bytes.
There are three types of shredders available:
- Medium Shredder costs 1,000 Bytes
- Large Shredder costs 2,000 Bytes
- Extra Large Shredder costs 5,000 Bytes
The shredder you choose depends on how much scrap you plan to process and what size debris you want to handle.
The Medium Shredder is a great early-game option. It’s affordable and perfect for smaller salvage pieces. The Large Shredder handles medium debris and is ideal once your base expands. The Extra Large Shredder is the most powerful option, capable of processing large wreckage pieces in bulk.
If you’re just starting out, the Medium Shredder is usually the most practical choice.
Step 2: Craft the Shredder
After researching your shredder, you’ll need the correct materials to craft it.
- The Medium Shredder requires 2 Iron.
- The Large Shredder requires 2 Iron and 1 Tungsten Carbide.
- The Extra Large Shredder requires 2 Tungsten Carbide and 2 Steel.
As you can see, the larger shredders demand more advanced materials. If you don’t yet have access to Tungsten Carbide or Steel production, sticking with the Medium Shredder is perfectly fine.
In addition to materials, you’ll need the correct printer.
- The Medium Shredder is printed on the Small Printer.
- The Large Shredder is printed on the Medium Printer.
- The Extra Large Shredder is printed on the Large Printer.
Your current printer setup may influence which shredder makes the most sense for your base.
Step 3: Place and Power the Shredder
Once printed, the shredder must be placed on an appropriate platform. It will not function if it is sitting loosely on the ground.
After placing it on a platform, connect it to a power source. This can be a generator, solar panel array, wind turbines, or your base power grid. Without power, the shredder won’t process anything.
Make sure your power supply is stable. Larger shredders consume more power, and interruptions can slow down your scrap production.
Step 4: Gather Salvage
Now comes the fun part, scavenging.
Scrap material can be found all over planets in the form of wreckage, debris, broken platforms, and unused crafted items. Exploration is key. If possible, bring a rover to increase your carrying capacity and speed up collection trips.
Dynamite can be extremely helpful here. Larger debris pieces often need to be broken down before they can fit into smaller shredders. Using dynamite lets you split oversized wreckage into manageable chunks.
If you don’t have dynamite, you’ll need a shredder large enough to handle the debris as-is. That’s where the Large and Extra Large shredders shine.
Smaller scrap pieces can be carried on your backpack or rover storage slots, making transport much easier.
Step 5: Feed the Shredder
With debris collected and your shredder powered, place the salvage directly into the shredder input slot.
The machine will activate automatically and begin processing the material. You’ll see scrap being extruded during the shredding process.
The amount of salvage required depends on the size and type of debris being processed. As you continue feeding the shredder, progress builds toward a completed scrap resource.
The Medium Shredder works best for smaller pieces. The Large Shredder handles medium debris more efficiently. The Extra Large Shredder can process bigger wreckage without needing dynamite to break it down first.
Technically, you can use dynamite to reduce almost any scrap into a size manageable by the Medium Shredder. However, if you’re processing high volumes, investing in a larger shredder saves time and effort.
Step 6: Collect Your Scrap
Once enough material has been processed, a full scrap resource block will be produced.
This scrap block can then be transported to a Trade Platform. From there, you can exchange it for a variety of resources, including harder-to-find materials that would otherwise require extensive planetary exploration.
This is where salvaging becomes incredibly powerful. Instead of constantly hunting for specific nodes, you can convert excess debris into tradable value and streamline your resource management.
Is Salvaging Worth It?
Absolutely.
Salvaging in Astroneer is one of the most efficient ways to repurpose unwanted items and generate consistent value. As your base grows and you automate more systems, scrap becomes a flexible currency that supports expansion.
Early game, the Medium Shredder is more than enough to get started. Mid to late game, upgrading to a Large or Extra Large Shredder dramatically increases efficiency, especially if you’re operating multiple rovers and gathering large wreckage fields.
Scrap trading also reduces reliance on risky planetary expeditions. Instead of traveling across dangerous terrain for specific resources, you can salvage locally and trade smart.
Final Thoughts
Astroneer rewards creativity and efficiency. Learning how to salvage scrap properly allows you to turn broken debris into opportunity. With the right shredder, steady power, and a little exploration, you can build a reliable scrap production system that fuels your entire operation.
Research the shredder that fits your stage of progression. Craft it with the correct materials. Power it properly. Gather salvage strategically. Then trade your scrap for exactly what your base needs.
In Astroneer, even junk has value, if you know how to use it.
