The platform has the following purposes:


  • the production of biogas using the anaerobic digestion section to process the incoming sludge;
  • the upgrade of biogas to biomethane;
  • the dewatering of residual waste from the anaerobic digestion that can later be briquetted and used in construction or disposed in sanitary landfills;
  • the production of lignite through innovative processes;


The proposed project features a multi-combined platform divided in two distinct sections:

  1. A sludge treatment section with capacity for 50.000 t/year for sludge collected in the Province of Foggia.
  2. A Waste Water Treatment Plant (WWTP) for liquid civil waste with a total capacity of 300 m³/day



The average quantity of clarified permeate will be approximately 156 m³ /day . The chemical composition complies with the limits specified on table 4, annex 5, part three of the Legislative Decree 152/06 and subsequent amendments, as well as adhering to the requirements concerning reuse of waste water reported on the Ministerial Decree 12 June 2003, n. 185
