Agenda / Inhalt Soluzione integrata per l‘abbattimento o, in alternativa, il recupero dei nutrienti nei digestati Integrated solution for the degradation, or alternatively, for the recovery of the digestate’s nutrients L.P. BZ 13.12.2006, n. 14 - “Innovation” Determines the financing Consorzio ALPI BIOGAS n. 5/08 23. gennaio 2014 1 Alpi Biogas Soluzione integrata per l‘abbattimento o, in alternativa, il recupero dei nutrienti nei digestati The centre of competence Alpi Biogas focusses his energies in the following activities: Research & Development: The innovation and application of new technologies in plants and processes are the objectives of R&D. The research is targeted on low volume agricultural plants and on specific solutions for the industry. The transfer of the know-how: We spin webs for connecting the right partners and build bridges between the research’s and the economy’s worlds. Experiment and monitoring: The pilot plants and demonstration plants permit the scientific monitoring of the research’s projects up to their concrete realization. 23. gennaio 2014 2 Alpi Biogas Biogas in aree alpine: soluzione integrata per l‘abbattimento o, in alternativa, il recupero dei nutrienti nei digestati Research Development farmers Industrialization of the plants and processes «Agro-energetic» centre of research and application Energetic companies January 23th 2014 Transfer of the know-how Control, monitoring craftsmen Center of formation Pilot plants Designers and technicians 3 Alpi Biogas Soluzione integrata per l‘abbattimento o, in alternativa, il recupero dei nutrienti nei digestati Scientific level University of Trento Agrarian Institute of S.

The reactions are: Nitrification (partial): Anammox: 2NH4+ + 1.5O2 => NH4+ + NO2- + H2O + 2H+ NH4+ + NO2- => N2 + 2H2O ACIDO The process is done by specific microorganisms – organisms «ANAMMOX» (Planctomycetales): autotrofic anaerobic bacteria observed for the first time in 1995 they contribute at 70% to the nitrogen cycle in the oceans 23. gennaio 2014 11 11 Stripping General Biogas in aree alpine: soluzione integrata per l‘abbattimento o, in alternativa, il recupero dei nutrienti nei digestati Nitrogen drawdown by means of a chemical process of desorption producing ammoniac in gaseous phase. The ammoniac produced is sent to a cleaning column (scrubber) from where it comes out in form of salt (ammonium sulphate). Actually this technology is not covered in the BAT (Best available technology).
