The effect of plantain peel ash on biogas production from cow dung.

Resumo

A study was carried out to investigate the effect of pretreatment with plantain peel ash on biogas production from cow dung. Two portable floating drum digesters of the same capacity were used for the experiment. One was filled with substrate prepared fromcow dung and the second was also filled with substrate prepared from cow dung but pretreated with plantain peel ash. Results showed that 11,998 cm3of biogas was produced from the digester that contained substrate of cow dung only while 20,493 cm3was produced from the digester that contained substrate pretreated with plantain peel ash. This showed that the increase in the volume of biogas produced as a result of plantain peel ash addition is 8,495 cm3which is equivalent to 70.8%
