Effect of solid content and pH on biogas production from organic fraction municipal solid waste

Abstract EN

The increasing demand on energy and the constraints on environmental aspects motivate the research on municipal solid waste to be an environmentally friendly source of renewable energy.

therefor using the organic fraction of municipal solid household waste in an aerobic digester to produce biogas and a digestate which can be used safely as fertilizer.

in this study three reactors of two liter volume are used to investigate the effect of total solid content (10%, 15%, 20%) and pH on the produced amount of biogas.

the results revealed that lower percentage of solid content yields the highest amount of biogas and the pH below 6.0 will inhibit the biogas production.

the percentage of methane from the 10% reactor was 50.2 % of the gas production.
