17. AMGA - NET project NET SpA and AMGA SpA are companies based in Udine.
NET SpA works on municipal solid waste collection and treatment.
AMGA SpA multiservices works on waterworks, water and wastewater treatment and other services.

18. AMGA - NET project
RISA is currently having a partnership with AMGA SpA and NET SpA to design and test an anaerobic co-digestion plant to convert FORSU and sewage sludge into biogas.

19. AMGA - NET project Oversized anaerobic digestion unit
FORSU high quantities to treat
Opportunity to treat waste as a resource
Anaerobic digester pilot plant

20. Objectives Design, realization and start up of a pilot plant.
Reach pilot plant stationary condition to reproduce real digester working.
Co-digestion step with various FORSU (fractions of organic material from municipal solid waste).
Finding of limit conditions for optimal biomass metabolism.
Pre-treatment test of matrices to be digested.
