Graminaceous BM (cereal stalks, straw), grasses (weeds, clovers, alfalfa), starch (maize, wheat, barley), sugars (cane, beet), and other high moisture herbaceous and aquatic plants (vegetables, sorghum, cotton, rushes, plankton), animal wastes, and municipal solid wastes have mainly been submitted to biological degradation via
microbic digestion and fermentation to produce bio-alcohols while those BM wastes deposited in landfills were demonstrated to be promising for biogas (methane) in situ production [16-20].
