EVALUATION OF BIOCHEMICAL METHANE POTENTIAL (BMP) OF VARIOUS ENERGY CROPS
Biogas production is a key technology for the sustainable use of agrarian biomass as renewable energy source. High energy yields per hectare can be achieved through biogas production. Biogas can be produced from a wide range of energy crops, animal manures and organic wastes 5. The aim of this research was to determine methane potentials of energy crops such as: rye (Secale cereale L.), Jerusalem artichoke (Helianthus tuberosus L.), sida (Sida hermaphrodita L.), canary grass (Phalaris canariensis L.), sorghum (Sorghum Moench) and to compare it with theoretical methane yield potentials. The methane potentials of all substrates were determined in batch experiments in 1 dm3 glass bottles (liquid volume 0.5 dm3) incubated statically at 37±1 ℃. All crop materials were used in the form of silage. Inoculum (sludge after anaerobic digestion) and substrate were added into the bottles, distilled water was refilled to produce a liquid volume of 0.5 dm3. The methane potentials of crops, as determined in laboratory methane potential assays, varied from 295 to 551 Ndm3 CH4 kg-1VS and from 55 to 119 Ndm3 CH4 t-1 ww (tons of wet weight). The highest value of the specific methane yield was obtained for rye and was equal to 119 Ndm3 CH4 t-1 ww, while the lowest one for canary grass 55 Ndm3 CH4 t-1 ww.
