The stuff at the bottom forms mature compost while the stuff at the top isnt compost at all. Yes, composting does create methane. The methanogenic bacteria convert hydrogen and acetic acid into methane gas and carbon dioxide. It changes the soil makeup, allowing better aeration and water retention. The substances are then converted into hydrogen, carbon dioxide, and acetic acid.

\nAerobic composting is the principle at work in aboveground composting environments whether it takes place in a freestanding pile or in a container that provides air circulation, such as a bin with open sides or a tumbler with aeration holes.
\nAs long as plenty of air is available, aerobic decomposers work faster and more efficiently than their anaerobic counterparts, providing you with finished compost on a faster timetable.

It happens all the time in nature at the bottom of marshes, bogs, and other areas deprived of oxygen but rich in organic matter.

There are circumstances where anaerobic methods are advantageous. Or forfall composting when you have vast amounts of fallen leaves (Bag composting is a popular way to deal with large amounts of organic waste). First, the material doesnt go dry at any point.

It also gives worms and other soil organisms access to the contents of the digester, though many will only feel at home after the bottom layer of material has passed through its most acidic phase and the pH starts to level off.
