Abstract

A study on the anaerobic digestion of maize wastes that are being indiscriminately dumped on Nigerian urban streets was undertaken. Maize chaffs, stalks and cobs were shredded and mixed in water to waste ratios ranging from 3:1 to 4:1 (water to wastes) and anaerobically digested in three separate 0.1 m3 digesters for 30 days. Some physco-chemical and microbiological analyses of the digesting substrates were carried out during the 30 days retention period to evaluate the progress of digestion. Results obtained show that even though maize chaffs, stalks and cobs have the potential to generate biogas, the chaffs produced more biogas than the other two wastes. It was also observed that the chaffs generated more methane gas than the other two and was the earliest to flame when tested.

 

Key words: Biogas, waste, anaerobes, digesters, maize.
