Methane recovery by anaerobic digestion of cellulosic materials available in Sahel
AbstractSeventy-day anaerobic batch digestions were carried out at 35°C in 100 ml glass vials in order to determine the methane potentials of four cellulosic materials available in developing countries. The substrates were millet bran and millet straw which were tested in N'Djamena (Republic of Chad), Calotropis procera leaves which were tested in Lyon (France), and brewing draffs from Moundou's brewery (Republic of Chad) which were investigated both in N'Djamena and Lyon so as to control data reproducibility. All substrates were broken into small pieces, except millet bran which was already in the appropriate form. The four substrates tested are suitable for methane recovery providing that pH is controlled by the addition of alkali in the case of millet bran digestion. The yields of methane as ml per gram of volatile solids from the four substrates were: millet bran 590, millet straw 390, Calotropis procera leaves 280, and brewing draffs 400 in N'Djamena and 385 in Lyon. These results could not be related to the chemical characteristics of the substrates as determined in this study. The validity of the experimental data was controlled by carbon balance calculations.
