CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishEfficient anaerobic digestion does not only represent a suitable solution for sludge disposal, but also provides additional energy gain from biogas use in cogeneration. Co-digestion of sewage sludge with additional compounds can be beneficial for the whole process because of the synergic interactions between substrates. Furthermore, the integration of different types of local resources often results in significant cost savings, e.g. transport costs. Following an agreement between two major Italian companies, Hera Spa (a leading multiutility in waste business) and the Granarolo Group (one of the most important Italian dairy industries), cheese whey was introduced as substrate in the TPAD system. The overall performance was interesting under both production and environmental standpoints, and whey can be introduced in a CO2-boosted TPAD system to improve methane production rate.

Furthermore, the integration of different types of local resources often results in significant cost savings, e.g. transport costs. Following an agreement between two major Italian companies, Hera Spa (a leading multiutility in waste business) and the Granarolo Group (one of the most important Italian dairy industries), cheese whey was introduced as substrate in the TPAD system.
