After the selective collection of organic waste, the waste is taken to an industrial composting plant where an accelerated anaerobic fermentation process takes place.
In cold or rainy places, the anaerobic digestion process is widespread.
The abovementioned process variables: moisture content, carbon-nitrogen ratio, temperature, pH, retention time, etc., are controlled, managed and optimized in order to achieve a faster and more complete degradation, with a minimum impact on the environment.
During the process, the oxygen supply necessary for the bacterial flora is controlled to ensure the correct aerobic fermentation of the organic matter. Water and high temperatures are also added to dry the organic matter. As the humidity level decreases, the bacterial flora suffers and the effectiveness and speed of the process decreases.
Darkness favors the proliferation of bacteria and microorganisms, and thanks to the previous supply of moisture and oxygen, accelerates the decomposition process of organic matter.
Microorganisms, such as bacteria, and large invertebrates such as earthworms and insects, help decompose crop residues by ingesting and mixing them with the parent mineral in the soil; in the process they recycle energy and nutrients from the plants.
