A biological stabilization is then performed within an environment that has
controlled temperature <strong>and</strong> humidity. The composting process (Picture 64.)
takes place in two treatment lanes which lie between two similar buildings.

(P.A.C., 2009)
The compressed material is churned once daily <strong>and</strong> is forwarded on a system of
bolts which are placed on a reversible bridge. After it has remained there for a
period of six (6) weeks under constant ventilation <strong>and</strong> churning, so that the
composition of the biodecomposite organic load <strong>and</strong> the production of very
fine-grained material may be achieved, it is led for refining.
Refining Unit
The compost material is led to the refining unit (Picture 65.) for final
treatment, which is the process of refining, during which unwanted material
(glass, hard plastic, gravel, plastic sheets, etc.) that pollute the material may be
removed. The final product that emerges from this treatment is the refined soil
improvement material (compost), which is a stabilized form of an organic
fraction of waste.
