Collecting Aerospace Materials in Arknights Endfield
Learn how to collect Aerospace Materials through Recycling Stations and upgrade the Dijiang space station for passive resource production in Arknights Endfield.
While Aerospace Materials won’t directly boost your Operators’ combat stats, ignoring them is a critical mistake. These specialized resources are the lifeblood of the Dijiang—Endfield Industries’ orbital headquarters. By investing in these materials, you unlock powerful passive resource generation systems that keep your operation running in the background.
While the collection process is largely automated, building a stockpile capable of high-tier upgrades requires smart planning and a bit of patience.

Finding Recycling Stations Across Talos-II
Aerospace Materials break the mold compared to other resources in Endfield. You won’t find them scattered around as loot or harvested from mining nodes. Instead, they’re exclusively obtained through Recycling Stations distributed throughout the game’s various regions.
Locating these stations is straightforward—scan your map for owl-shaped icons marking their positions. Each region contains multiple stations, giving you plenty of collection points once you’ve explored thoroughly.
Activating a Recycling Station costs nothing. Walk up to one, interact with it, and immediately claim your first batch of Aerospace Materials. But here’s the clever part: these stations continuously regenerate their inventory over time, creating a reliable passive income stream.
The regeneration cycle takes approximately 10 hours between collections. This timer encourages regular check-ins rather than marathon farming sessions, perfectly complementing the game’s overall progression rhythm.

Maximizing Output Through Station Upgrades
Basic Recycling Stations provide 3 Aerospace Materials per collection cycle—functional but underwhelming for serious Dijiang development. Upgrading these stations dramatically improves their value proposition in two significant ways.
First, upgraded stations generate larger quantities of materials per regeneration cycle. More materials per collection means faster progression toward your Dijiang expansion goals.
Second, and perhaps more importantly, upgrades unlock access to higher-rarity Aerospace Materials. These premium variants are essential for advanced Dijiang improvements and cabin constructions that produce the most valuable passive resources.
The upgrade system creates meaningful decisions around resource allocation. Do you spread upgrades across many stations for broader coverage, or focus on maximizing a few key locations first?
Earning Stock Bills for Upgrades
Station upgrades require Stock Bills—regional currency distinct from the T-Creds used for Operator advancement. Understanding the Stock Bill economy is crucial for efficient Aerospace Material farming.
Stock Bills circulate within specific regions of Talos-II, used primarily for purchasing materials and services from local populations. The most reliable acquisition method? Outpost trading systems.
Your AIC factories produce various materials and processed goods. Outposts near your operations will purchase these products, exchanging them for Stock Bills. Different items command different prices, creating opportunities for optimization.
Smart traders pay attention to market demand. Open your Outpost Management interface and examine current pricing for items you can produce. Supplies in high demand fetch premium prices, maximizing your Stock Bill income per transaction.

Strategic Outpost Trading
Turning factory output into Stock Bills requires more than just dumping excess materials at the nearest Outpost. Consider these optimization tactics:
Monitor price fluctuations – Outpost needs change over time. What sells for premium rates today might be worthless tomorrow. Check prices regularly before committing to large production runs.
Diversify your product portfolio – Don’t focus exclusively on one tradeable item. Spreading production across multiple goods provides flexibility when market conditions shift.
Balance production capacity – Ramping up factory output to maximize trading income means ensuring your power infrastructure and logistics chains can support the increased throughput.
Consider transportation logistics – Outposts scattered across the map require travel time for deliveries. Stations closer to your main base offer convenience, while distant ones might provide better prices that justify the journey.

Investing Aerospace Materials Wisely
Once you’ve accumulated Aerospace Materials, spending them strategically maximizes your returns. The Dijiang offers two primary investment categories:
Dijiang Control Nexus upgrades – These fundamental improvements unlock new capabilities and increase the station’s overall efficiency. Prioritize these upgrades early to expand your options.
Cabin construction – Additional cabins enable passive production of valuable materials including rare resources like Red Boletes and Kalkonyx. These run continuously, even when you’re offline, providing steady income without active gameplay.
The passive production aspect makes Aerospace Material investment particularly valuable. Unlike active farming that requires constant attention, properly upgraded Dijiang systems generate resources around the clock, dramatically accelerating your overall progression.
Planning your upgrade path matters. Some cabin types produce universally useful materials, while others generate specialized resources for specific purposes. Consider your current bottlenecks and future crafting needs before committing materials to construction projects.

Long-Term Collection Strategy
Aerospace Material acquisition rewards consistency over intensity. Here’s how to maintain steady growth:
Establish collection routes – Plan efficient paths through regions that hit multiple Recycling Stations in sequence. Regular routes ensure you’re claiming materials as soon as they regenerate.
Set collection reminders – The 10-hour regeneration cycle means twice-daily collections maximize throughput. Morning and evening check-ins work well for most schedules.
Prioritize station upgrades near high-traffic areas – Upgrading stations you pass frequently ensures you rarely miss collection windows, while remote stations might regenerate unused for days.
Scale factory production for trading – Your Stock Bill income directly limits upgrade speed. Expanding production capacity for high-value trade goods accelerates station improvements, which in turn boost Aerospace Material collection.

Frequently Asked Questions
How many Recycling Stations exist in each region?
Each region contains multiple Recycling Stations, though exact numbers vary by area size and layout. Early regions like Valley IV have fewer stations scattered across smaller territories, while later regions expand both geographically and in station density. Thorough exploration reveals all available stations—look for owl icons on your map and systematically visit unexplored areas to locate them all.
Should I upgrade all Recycling Stations equally or focus on specific ones?
Focus your initial upgrades on stations positioned along routes you travel frequently during normal gameplay. Upgrading every station sounds ideal but requires massive Stock Bill investment that could take weeks to accumulate. Concentrating upgrades on 3-4 conveniently located stations provides better returns since you’ll actually collect from them regularly, while remote stations might sit unclaimed for days regardless of their upgrade level.
What’s the most efficient way to farm Stock Bills for station upgrades?
Monitor your Outpost Management screen to identify which products currently command the highest prices, then configure your factory production to emphasize those items. Processing raw materials into refined goods typically offers better Stock Bill returns than selling basic resources. For example, selling refined metal parts usually generates more currency than raw ore. Balance this against production costs—the highest-priced items aren’t always the most profitable after accounting for manufacturing expenses.
Do higher-rarity Aerospace Materials come from upgraded stations automatically?
Yes, upgrading Recycling Stations automatically includes higher-rarity materials in their regeneration pools. You don’t need to perform additional actions beyond the upgrade itself. However, the exact rarity distribution depends on upgrade level—higher station tiers produce better material ratios. This makes upgrading particularly valuable since rare Aerospace Materials are required for the most impactful Dijiang improvements and advanced cabin constructions.
