After the maturation phase, the final processing steps take place.
The raw compost undergoes one last refining stage before commercialization through a rotary screen, ensuring a uniform particle size distribution, while the oversized fraction is purified from the remaining unwanted materials and recirculated back to the beginning of the production process.

This is the moment when the product finally reveals its complete identity: after three months of treatment, including biostabilization and maturation, the biological transformation process is complete.

Refining is not merely the final step — it is a crucial phase in which the characteristics that make compost a reliable, high-quality product are fully defined: homogeneity, purity, and suitability for agronomic use.
All of this is supported by rigorous analytical testing that certifies the quality of our compost and confirms characteristics that tell their own story of genuine excellence.

It is here that the entire process finds its synthesis, transforming the work carried out over previous weeks into a tangible result, ready to return to the soil and generate new value.

With this stage, our journey through the facility comes to an end: a path that has taken us inside every phase of the composting process, from the management of organic waste to the production of a natural soil amendment.

A complete cycle that demonstrates, in a concrete way, what circular economy truly means.

But the journey of discovery does not end here.
