  1. Work Package 2 Potential to produce Methane from extraction By-products Through Anaerobic Digestion FORTH G. Antonopoulou, K. Stamatelatou and G. Lyberatos 24 April 2009, Foggia, Italy

  2. Methane production from rapeseed and sunflower meal Biochemical Methane Potential (BMP) tests on rapeseed and sunflower meal • Selection of both feedstocks • Characterization of their physicochemical and biochemical parameters • Application of pretreatment methods for enhancing the methane potential and their biodegradability - thermal ( 1bar, 121oC for 60 min ) - alkaline treatment (NaOH) - acid treatment (H2SO4)

  3. Potential to produce Methane from Rapeseed meal 24 April 2009, Foggia, Italy

  4. Methane production from rapeseed meal m3 CH4 t rapeseed meal Yield = 423 24 April 2009, Foggia, Italy

  5. Methane production from rapeseed mealEffect of thermal pretreatment • Conditions : 60 min in 120oC, 1.2atm Only 2.8 % increase 24 April 2009, Foggia, Italy

  6. Methane production from rapeseed mealEffect of alkaline pretreatment • Alkaline : 60 min in NaOH (2%w/v) • Thermal alkaline: 60 min in 120oC, 1.2atm, with NaOH (2%w/v) 24 April 2009, Foggia, Italy

  7. Methane production from rapeseed mealEffect of acid pretreatment • Acid : 60 min in H2SO4 (2%w/v) • Thermal acid: 60 min in 120oC, 1.2atm, with H2SO4 (2%w/v) 24 April 2009, Foggia, Italy

  15. Potential to produce Methane from Olive pulp – (2phase OMW) 24 April 2009, Foggia, Italy

  16. Olive pulp • High humidity • Difficult to store, transfer and further process to extract the seed oil • Material rich in carbohydrates and organic content(Guillénetal, 1992) Suitable for biofuels production such as hydrogen, methane 24 April 2009, Foggia, Italy Semi solid residue (Borja et al, 2006) Coming from the two phase extraction of olive oil

  17. Methane production from olive pulp 24 April 2009, Foggia, Italy • Possible to produce biogas under mesohilic (35 C) and thermophilic (55 C) conditions • Continuous operation of bioreactors (CSTR) • Working volume 3L • Stable operation under Hydraulic Retention Times from 20 d to 10 d (mesophilic) and from 20 to 3d (thermophilic)
