This dataset contains graphical representations (.png) of FTIR spectra for four organic and organo-mineral samples. The spectral analysis was performed to identify functional group changes during the valorization of digestate.

\n\nList of analyzed samples:\n
    \n
  1. Peat (Reference material)
    2. \n
  2. Solid Digestate (Raw material from anaerobic digestion)
    3. \n
  3. Digestate Biochar (Pyrolyzed digestate)
    4. \n
  4. Digestate + (NH4)2SO4 (Organo-mineral fertilizer enriched with ammonium sulfate)
    5. \n
\n\nMethodology:\n

The FTIR spectra were recorded using a Nicolet iS50 FT-IR spectrometer (Thermo Fisher Scientific, USA) equipped with a GladiATR diamond ATR accessory (PIKE Technologies, USA). Measurements were performed at a resolution of 2 cm-1, with 32 scans, in the spectral range of 4000–600 cm-1.
