Pinerolo

The plant system consists of four plants, each other physically interconnected:
• Air-exploitation (for dry lines production of RDF and line wet digestion anaerobic organic fraction)
• Wastewater treatment plant (75000 inhabitants equivalent)
• Composting plant
• Landfill
The line of treatment of organic waste from separate collection provides:
• Mechanical pre-treatment
• The preparation of mixing for density and temperature (55-65°C) in a intermediate tank (185 m3)
• The supply to the digester (volume of 2600 m3) takes place in discontinuous mode (180 m3 max)
• The discharge of the product from the digester phase and the transfer of that to the aerobic phase
• The biogas is sent to two internal combustion engine: Guascor 950 kWe and CAT3516LE 1106 KWe; preceded by a gasometer and a pretreatment of the gas itself.
The biogas production is 4,400,000 m3/a with a specific biogas production of 60 % CH4/t and a digested production/total biomass of 15-20.
