Biomass is important in LEGO Fortnite because it's needed to make power cells for vehicles. If you learn how to make biomass in LEGO Fortnite, you will have a huge advantage in the game. This lets you travel the game map a lot more easily. Let’s take a look at everything you need to know about biomass in LEGO Fortnite!

What is biomass in LEGO Fortnite?

In LEGO Fortnite, players need various resources to progress, and biomass is one such essential resource. Biomass helps create power cells, which are crucial for powering vehicles in the game. These vehicles allow players to explore further and do more within the game map.

To make power cells, you need both biomass and glass. You can find glass in places like bandit camps. However, getting biomass involves a specific process using a compost bin. In this bin, players can deposit meat or other organic items, which compost into biomass and possibly other items like soil or fertilizer.

How to get biomass in LEGO Fortnite

First of all, everything starts with building a Compost Bin. This bin is essential for turning organic waste into biomass, a valuable resource for crafting. To make a Compost Bin, gather the following materials: 5 wooden planks, 1 sand, 2 soil, and 3 fertilizer. Once you have these, you can assemble your Compost Bin at a Crafting Bench. This bin is a crucial tool for managing resources.

Once your Compost Bin is ready, you need to fill it with organic materials. Meat is a common choice, obtained from animals like cows, wolves, and sheep in the game. Place the meat into the Compost Bin to start the composting process. This process transforms the organic waste into biomass over time. While you wait, you can explore other parts of the game.

What can you make with biomass?

The Compost Bin can process various materials, but some are more effective than others. For example, bones are particularly good for producing biomass quickly. Each bone you compost can yield two pieces of biomass. This makes bones a great choice if you want to gather biomass efficiently.

Other items like Brute Scales and Frost Brute Scales can also be composted for biomass, each yielding up to three units. This variety gives players multiple ways to collect the resources they need. While you can compost many different items, using bones for biomass is one of the simplest and most efficient methods.


As you play LEGO Fortnite, keep in mind that managing your resources well is a very important aspect if you want to build more and play more. Biomass makes it easier to keep your vehicles running so you can explore the big game world. If you follow these steps, you'll have all the biomass you need. This was all for biomasses but we have more guides on the website. If you want to get better at Fortnite, don’t forget to check this guide out:

FAQs

How to get the most biomass in LEGO Fortnite?

The most effective way to gather biomass is through the Compost Bin, which converts organic materials into usable biomass. To maximize output, focus on high-yield items such as bones, Brute Scales, and Cursed Bones. Bones give a reliable amount per unit, while Brute Scales and Cursed Bones provide slightly more biomass each. Collecting these items from enemies, caves, or specific biomes ensures a steady supply. Organizing your collection trips to focus on areas rich in these materials significantly increases the amount of biomass you can process. Always check your inventory before heading to the Compost Bin to avoid wasting time with low-yield materials.

Do bones give you biomass in LEGO Fortnite?

Yes, bones are a primary source of biomass. Each bone processed in the Compost Bin yields 2 biomass, making them highly efficient compared to other basic organic materials. Bones are obtained by defeating skeletons, which typically appear at night or in certain biomes. Regularly farming skeletons ensures a consistent supply of bones for biomass production. 

How to get 50 biomass in LEGO Fortnite?

To get 50 biomass efficiently, you need to combine high-yield materials. Composting 25 bones will give exactly 50 biomass. Alternatively, using Brute Scales or Cursed Bones, each providing 3 biomass, requires about 17 items to reach 50. Prioritize collecting materials that yield more biomass per unit, but keep bones as your fallback if high-tier materials are scarce. Planning your collection routes and focusing on the right materials allows you to reach 50 biomass quickly without wasting time.
