Three Bin System
A three-bin composting system uses three side-by-side bins to keep compost at different stages of decomposition, making the process faster and more organized. Fresh food scraps and yard waste go into the first bin, partially decomposed material is transferred to the second bin, and finished compost cures in the third. This setup allows for a steady rotation of materials so you can continuously add new scraps while still producing mature, ready-to-use compost. It’s an efficient system for households or community gardens that generate a lot of organic waste and want a dependable, well-managed composting process.

Recipe
2-1
To create the best multi-use compost we recommend using a 2-to1 ratio of browns to greens. This layering will look like lasagna, for every two layers of high carbon rich organic material, add a layer of nitrogen (green) material.
Cycle
Temperature Phases
As an outdoor composting system, the one-bin system will go through different temperature phases. Mesophilic phase, this is where the compost will start to get warm 70-100°F. During the thermophilic phase the pile's temperature can range between 100 to 155°F, this phases indicates high microbial activity. The mature phase occurs when the pile is cooling down ready to be sieved and used.

Turning and Watering
Converting the feed stocks into compost can take 4 to 6 months, during this time you need to water and turn it. During the first month and half, the mile will need constant turning and water. You'll know if the the moisture is just right by doing the squeeze test.
Trouble Shooting
Composting doesn’t always go perfectly, but with a few simple tweaks and easy fixes!
Bad Smells
Smells can occur when there is too much green material, not enough air flow or the bin is too wet.
To solve this try increasing the amount of turning, add more brown material and or reduce the amount of green waste.
The best way to get rid of them is to burry the food completely and reduce the amount of feeding rate and amount.
Pile is too hot or
not heating up.
The lack of heat can be due to to the lack of moisture, green material, or the pile isnt big enought.
If the pile is hotter then 155°F the heat will start killing the good microbes.
Compost is too Dry/Wet
If pile is too dry, it has too much brown material.
If pile is too wet there is too much green material or there is not sufficient air flow.
