Depending on the waste nature, the treatment process may have different characteristics to fit best the peculiarity of the product to be stabilized.
Generally, the emissions of the stabilization process require an environment that carefully avoids smelly gas leakage during the processing phases. 

An industrial shed is then built with the suitable insulation and completed with a deodorizing plant that makes smelly leaks impossible.
In the shed a preliminary selection of the material is done by specific sifters and appliances to separate solid substances, metals, plastic and, generically, non-biodegradable substances. 

The combustible organic part, instead, is sent to a stabilization section where it can be kept under controlled aerobic conditions (with process air insufflation) for the required time for the stabilization (28 days approximately). 

The selected material is then sent to a ripening zone where it stays for 30 more days to complete the oxydation reactions.
The material thus stabilized can be reused for rises formation, dump coating and, generically for green areas formation.
