Biomass has become in high demand ever since Epic Games introduced the new item with their major LEGO Fortnite 29.10 update.
Epic’s patch focuses on LEGO vehicles, but to drive any of these three shiny new vehicles to travel quickly around your world, you will need to power them with Power Cells.
However, this is where the problem lies. Making Power Cells can prove tricky — to make a decent stack of these cells, you will require tons of Biomass. Just creating one piece of Biomass has already proven challenging for many players and left many unsure of the fastest way to create them.
But, don’t worry, we’ve got you covered. Here’s the best way to get Biomass in LEGO Fortnite.
How to create Biomass in LEGO Fortnite
To get Biomass in LEGO Fortnite, you will need to place items in a Compost Bin to produce Biomass.

You can put different items into a Compost Bin to create Biomass.
Whatever you put into the Compost Bin will output either Biomass, Fertilizer, or Soil. However, what you get and how many you get is decided by which items you throw into the compost.
E.g. If you place Raw Meat in the Compost Bin, it will create one Biomass and one Fertillizer, but will not create any Soil.
To build a Compost Bin, you’ll need:
- 5 Wooden Planks
- 1 Sand
- 2 Soil
- 3 Fertilizer
Best way to get Biomass in LEGO Fortnite
Epic has not officially stated which resources are capable of composting into either of these three outcomes or the amounts you will receive. But, thanks to the LEGO Fortnite community, we have been able to provide all the best resources for you to use to get Biomass.

You can now build a Compost Bin in LEGO Fortnite as part of the 29.10 update.
Here are all the items you can compost to get Biomass in LEGO Fortnite and the amount they can produce:
- Brute Scale (3)
- Cursed Bone (3)
- Frost Brute Scale (3)
- Bone (2)
- Ice Shell (2)
- Sand Shell (2)
- Shell (2)
- Bread (1)
- Cheese (1)
- Common Seed (1)
- Corn (1)
- Egg (1)
- Epic Seed (1)
- Flour (1)
- Fruit Pie (1)
- Grilled Corn (1)
- Grilled Egg (1)
- Grilled Meat (1)
- Raw Meat (1)
- Meat Pie (1)
- Milk (1)
- Mushroom (1)
- Pizza (1)
- Pumpkin Pie (1)
- Slap Juice (1)
- Slurp Juice (1)
- Snowberry Shake (1)
- Spicy Burger (1)
- Uncommon Seed (1)
We would recommend using Bones as the best way to quickly produce Biomass, as it can produce two pieces of Biomass per Bone, and they are the easiest to get in comparison to all the others in the list.
Despite there being more items that produce more Biomass, it won’t be worth it as they take longer and are much harder to obtain.
How to use Biomass in LEGO Fortnite
You will need to use Biomass to create Power Cells to fuel any of your vehicles. Making Biomass has proved to be no easy task and unfortunately, you will need numerous to craft just one Power Cell using a Crafting Bench.
To craft a Power Cell, you’ll need:
- 50 Biomass
- 6 Glass
