Because composting involves moisture and heat, your bin will need to be able to withstand all of these elements. Thankfully, most store-bought plastics will be able to handle most composting pressures.
One other factor to consider is the smell. If your bin is located outdoors, it’s a nice gesture to be respectful of neighbors; if your bin is indoors, it’s a must. This problem is usually solved by changing the ratio of compost material within your bin and double-checking that the lid is securely tightened.
DEPTH
Intuition would have it that the bigger the bin you use, the more compost you’ll be able to create. Unfortunately, intuition doesn’t always lead us to the correct answer. To help explain why this is the case, we must first focus on what is going on inside the bin itself. It’s here where our composting rock stars take center stage. Eisenia fetida, or red wigglers, are the type of worms that do the best job converting old waste into usable compost. Unlike their earthworm cousins, red wigglers prefer to live on the top six inches of the soil, making them surface dwellers. Using a tall bin is fine as long as compost ingredients are added in thin batches, ensuring that your worms will be able to reach the lower levels.
