In a post-apocalyptic world filled with zombies, players must use what they can findaroundProject Zomboid’s Kentucky if they hope to survive for any reasonable amount of time. Part of that survival means creating a sustainable farm that makes good use of compost.

To make compost, you’ll need to train your Carpentry skill and ensure you have the right materials and space for the composter box, after which you can start recycling unwanted food and plants without much hassle at all.

How To Craft A Composter

A composter is one of the easier pieces of furniture to craft, and you’ll unlock it once you have progressed yourCarpentry skill to level two. you may do this bystarting with the Carpenter professionat the beginning of the game or bydissembling furniturelikebedsandclosets.

You can add anXP multiplierby reading specializedCarpentry booksfound on shelves.

If you canfind WoodcraftandExposure Survival VHS tapeson shelvesand a TVwith power,you may get passive learningwhile also decreasing your boredom by being near the TV.

During the first nine days, you canwatch the"Life and Living" channelto occasionallyget a buff to your skillsbased on what episode is playing.

Once your Carpentry level is high enough, you’ll need tofind five wooden planks and four nails. These can be acquired bydisassembling furniture with the right tools, as shown when youhover over the ‘Disassemble’ optionin the Right-Click menu. You can alsofind these resources in constructionor maintenance areas.

Obtaining planks through disassembling furniture isn’t consistently reliable. If you have access to anaxeand asaw, a more reliable alternative is to acquire planks bychopping down treesandsawing them.

To place the composter, you need tohold the supplies and left-click the optionthrough the Carpentry menu. You’ll know it’s placed and available if you canopen the container’s inventoryin a separate window, as shown above.

How To Use A Composter

Project Zomboidtries to make using the composter as simple as possible. All you have to do isdrag any unwanted food or foraged itemsfrom your inventory directlyinto the open containerscreen.

Whileyou can place fresh and frozen foodin the composter, it will need togo through the rotting process firstbefore it’s composted. For this reason, it’s wise tostart with foraged foods.

By default, Rotten food inside the Composter willtake two weeks to turn into compost. It will ‘disappear’ from the inventory and begin to fill the box, raising the percentage. Thetime it takes to compost can be lowered or raisedwhen generating a Custom Sandbox worldunder the ‘Nature’ tab.

You cancheck the level of compostat any time byright-clicking the Composterwhile you’re standing next to it. Once the compost is in the box, you’ll eitherneed an empty Sack or a partially filled Compost Bag.

Once you have some compost transferred to a bag, you canuse the compost on your crop plotsto help plants grow faster.
