– Reduce the volume of sludge, approximately 65,700 m3/ year to approximately 43,800 m3/ year,
– Installation of 1.25 MW cogeneration facility that will cover 71% of the energetic needs of the plant, the heat will be used by the digester,
– The generation of 8.52 GWh / year will displace the electricity demand and will help to reduce approximately 9,583 metric tons/year of CO2 and 6 metric tons / year of NOx and 7 tons metric/year of SO2,
Lower energy consumption by upgrading the technology,
