How to Make Chemfuel in Rimworld (Best Methods)

Chemfuel is one of the most useful resources in Rimworld. You can use it for:

• Power generation ⚡
• Mortars 💥
• Transport pods 🚀
• Flame weapons 🔥

If you’re wondering how to make chemfuel in Rimworld, here are the best methods — from early game to late game.

🛢️ What Is Chemfuel in Rimworld?

Chemfuel is a combustible resource used to power various machines and weapons.

Common uses include:

• Fuelled generators
• Drop pods / transport pods
• Mortars
• Incendiary weapons
• Certain mods and advanced systems

👉 Having a stable chemfuel supply becomes very important mid to late game.

---

🧪 Method 1: Make Chemfuel at a Biofuel Refinery

This is the main vanilla method.

---

🏗️ Step 1: Research Biofuel Refining

Before you can produce chemfuel, you need:

👉 Research: Biofuel Refining

Once completed, you can build:

• Biofuel Refinery

---

🏭 Step 2: Build a Biofuel Refinery

To build it, you’ll need:

• Steel
• Components

Place it somewhere indoors if possible.

---

🌽 Step 3: Use Organic Materials

A biofuel refinery converts organic matter into chemfuel.

You can use:

• Wood
• Hay
• Food
• Plant matter
• Corpses (yes, really)
• Organic waste

---

⚙️ Step 4: Create the Chemfuel Bill

1. Click the refinery
2. Select Bills
3. Add:
   👉 Make Chemfuel From Organic Matter

Colonists will automatically start refining materials into chemfuel.

🐄 Method 2: Boomalope Farming (Best Passive Method)

Boomalopes are living chemfuel factories.

---

🐾 How It Works

Tamed Boomalopes can be milked for:
👉 Chemfuel

This produces a steady passive supply with almost no processing needed.

---

⚠️ Important Warning

Boomalopes explode when they die.

So:

• Keep them away from your main base
• Use fireproof pens if possible

---

☣️ Method 3: Convert Waste (Biotech DLC)

With Biotech, some systems and waste processing methods can generate chemfuel indirectly.

This is more advanced and usually late-game focused.

---

🔥 Best Uses for Chemfuel

Once you have a supply, chemfuel is amazing for:

⚡ Fuelled Generators

Reliable power early game.

🚀 Transport Pods

Essential for:

• Trading
• Raids
• Toxic waste disposal

💣 Mortars

Needed for explosive shells.

🔥 Flame Weapons

Useful but risky.

---

⚠️ Chemfuel Safety Tips

Chemfuel is EXTREMELY flammable.

Never:

• Store huge amounts near bedrooms
• Put it beside generators
• Keep it near batteries or mortar shells

💡 Best practice:

• Use a separate stone storage room

---

🧠 Pro Tips for Easy Chemfuel Production

• Grow extra haygrass specifically for refining
• Use boomalopes for passive income
• Keep refinery workers near storage
• Store chemfuel in small stacks to reduce explosion risk

🎯 Final Thoughts

If you want to know how to make chemfuel in Rimworld, the easiest methods are:

✅ Biofuel refinery
✅ Boomalope farming

Both are powerful, and once you have a steady supply, your colony becomes much more advanced and mobile.

👉 Just remember: chemfuel is incredibly useful… and incredibly explosive.
