One study on biogas production potential character of coffee husks

摘要

Taking the fresh coffee husks as the raw material and the cultured active sludge as the inoculums to operate the measurement of biogas yield potential research, under mesophilic (35 °C) and ambient temperature conditions. In this paper, the biogas yield, cumulative biogas production and biogas production rate were analyzed. The biogas yield potential of coffee husks were 494 ml/g TS and 544 ml/g VS under mesophilic condition and 365 ml/g TS and 402 ml/g VS under ambient temperature condition respectively.
