Plant description
The project proposal therefore envisages the conduct of waste management operations R3 – R4 – R13 – D8 – D13 – D15 as indicated in Annex B and C of the fourth part of Legislative Decree.
The activities that take place inside the plant can be divided as follows:
A. FORSU TREATMENT SECTION
- Mechanical pre-treatments
- Anaerobic digestion, biogas production, biomethane refining
- Production of quality compost
B. ORGANIC MECHANICAL TREATMENT RUR
- Mechanical separation treatments;
- Anaerobic stabilization, biogas production, cogeneration
- C.S.S. production
The organic treatment of FORSU produces a quantity of quality compost equal to about 21,000 t / year and biomethane production equal to about 490 Sm3 / h. Instead of the treatment of RUR we obtain a quantity of stabilized organic fraction (FOS) equal to about 19,000 t / year, of recyclable materials equal to about 22,000 t / year and a biogas production equal to about 430 Nm3 / h.
