Plant Description

The proposed plant layout has the main objective to develop a new and larger configuration of an existing composting plant for organic waste treatment and high-quality compost production. The project also provides the technology improvement for the process.

The enlargement of the existing plant consists in the construction of a new building in which the composting process will start inside no. 12 closed tunnels (process period 4 weeks).

After the intense composting phase, the material will be moved to the final maturation section (after screening operation). This phase will occur in dynamic windrows subjected to forced ventilation inside a closed concrete building. A further final maturation phase is also provided through static windrows, so that the composting process can be completed, obtaining a high-quality compost for sales.

The project provides an increasing of the composting treatment capacity equal to 30.000 t/year, which increases, together with the existing authorized capacity 26.000 t/year (AIA authorization released by D.D.S. n. 1897 del 12/11/2014 for R3, R13 operation), the plant capacity up to 56.000 t/year.
