    Abstract: A vertical manure converter and related process of using activated carbon in an activated carbon/organic material mixture to process organic waste. Inducing air, preferably compressed, into a chamber of the converter in combination with reusing activated carbon can result in a continuous process. The temperature can be controlled by regulating the air into the chamber. The vertical manure converter takes organic waste and uses heat to accelerate the composting process wherein final products can be purified water and ash fertilizer.
