    • Colombia generates 1 `231.200 ton/y of waste stem banana and 14'700 000 ton/y in the world [1] .
    • CH 4 production is equal to 738 600 ton/year.

    • ¿How much will be affected kinetic and methane production by temperature in cattle anaerobic and banana stem vegetable wastes codigestion ?
    OUR RESEARCH QUESTION
  • 7. GENERAL OBJECTIVE
    • To evaluate temperature effect in mesophilic and thermophilic conditions in methane production from cattle and banana stem vegetable waste co-digestion.
  • 8. SPECIFIC OBJECTIVES
    • To assess the influence of livestock/vegetable wastes in methane production during co-digestion.
    • To determine kinetics of methane production at different temperatures.
    • To determine the COD, total solids, fixed solids, volatile solids and humidity, in livestock and vegetables waste co-digestion treatment.
  • 9. EXPERIMENTAL DESIGN VARIABLE TEMP . VARIABLE: SUBSTRATE RATIO X = vegetable m/ (vegetable m + animal m) (%) X1 = 0 X 2 =1/3 X3=2/3 X4 =100 (33.3) (66.6) T1 (25ºC) T1, X1 T1, X2 T1, X3 T1, X4 T2 (35ºC) T2, X1 T2, X2 T2, X3 T2, X4 T3 (45ºC) T3, X1 T3, X2 T3, X3 T3, X4           Total Treatms. 12   Total assays 36

  • 19. CONCLUSION
    • By increasing the temperature it can be obtained energy in methane structure from waste cattle and banana stem co-digestion, which are abundant in banana plantations and cattle areas in Colombia and other tropical countries, achieving a great reduction of greenhouse gases emissions.
