What is the composting process?

Firstly, put the manure into the compost tower. Moisture rate of fresh manure is around 75% to 80%, which is too wet to be decomposed. So first thing we need to do is remove moisture.

The temperature inside the compost tank is high, causing some of the moisture to evaporate. This stage is referred to as the dehydration stage.

After the dehydration stage, the moisture content of the manure decreases to around 60%. With suitable temperature and sufficient oxygen, it creates an ideal environment for the growth of microorganisms. As a result, microorganisms multiply in large numbers. The organic matter in the manure serves as a nutrient source and is rapidly decomposed. At the same time, moisture continues to evaporate, and the moisture content keeps decreasing. This stage is called the fermentation stage.

After this process, the organic matter content decreases, and the nutrient source reduces, resulting in a slowdown in its reproduction rate and a decrease in temperature. However, residual organic matter is still slowly decomposed, and the moisture content gradually decreases. This stage is referred to as the maturation stage.


After the maturation stage, the material is discharged from the fermentation tank. At this point, the material is loose and odorless, completing the transformation from manure to organic fertilizer.
