Cairn How to Compost
Composting in Cairn is how you turn unwanted items into chalk, but it is easy to misunderstand and accidentally clog your inventory. Composting does not automatically dump items or clear your bag, and knowing how the Climb Bot works fixes most confusion.
This guide explains exactly how composting works, how to avoid filling your inventory, and what to do with trash.
How Composting Works In Cairn
Composting converts items into chalk using the Climb Bot.
You must be on the ground or hanging from a piton to access your backpack. Open the backpack and highlight any item you want to compost. Hold the compost button and the item disappears, starting a chalk timer on the Climb Bot.
When the timer finishes, the Climb Bot shows Ready in the backpack menu.
How To Compost Items Step By Step
Open the backpack
Highlight an item
Hold the compost button
The item is removed and a timer starts
Wait for the Climb Bot to finish
Collect the chalk when you need it
You can compost most items, not just trash, so pay attention to what you select.
Why Composting Feels Like It Fills Your Inventory
Composting itself does not fill your inventory.
The problem happens when you collect chalk even though your chalk bag is already full. Extra chalk goes into your backpack instead of disappearing.
If you keep collecting chalk every time it is ready, your bag fills up fast.
How To Avoid Filling Your Bag With Chalk
You do not need to collect chalk as soon as it is ready.
Leave finished chalk sitting in the Climb Bot until you actually need to refill your chalk bag. The Climb Bot can hold chalk indefinitely.
This lets you keep composting trash without adding new items to your backpack.
What To Do With Trash Items
Trash items are meant to be composted.
Food often creates trash after being used, and that trash must also be composted separately. If your bag is full of wrappers or cans, compost them one by one and let the Climb Bot hold the finished chalk.
There is no manual drop or discard button for items.
Can You Compost While Chalk Is Ready
Yes.
If the Climb Bot is Ready and you compost more items, the extra material is not wasted. It reduces the timer for the next chalk cycle once you collect the current one.
The key rule is simple. Compost often, collect chalk only when your chalk bag has space.
Final Blurb
Composting in Cairn is simple once you stop grabbing chalk too early. Turn trash into chalk, let the Climb Bot hold it, and only collect when you need it. If your bag feels like a landfill, it is not the composting that broke, it is the timing.
