Comparison of Methane Production from Different Municipal Biomass Waste
Municipal biomass waste has been regarded as renewable new energy. Recovery methane from those wastes by anaerobic digestion was a classic process. Since different wastes have different components, they bear different methane production potential. In this paper, five biomass wastes: cow manure, pig manure, municipal sludge, fruit/vegetable wastes and food waste were evaluated for methane production. Considering the difficulty of hydrolysis process, a hydrothermal pre-treatment was used to heat the raw materials before digestion. BMP test was used to evaluate the biogas production before and after hydrothermal pre-treatment. Results show that fruit/vegetable waste and food waste could produce more methane than cow manure, pig manure and municipal sludge. After hydrothermal heating, the biogas production could increase by 7.8%, 13.3%, 18.5% and 67.8% for pig manure, cow manure, fruit/vegetable wastes and municipal sludge respectively. Methane production has been increased by 14.6%, 16.1% and 65.5% for pig manure, fruit/vegetable wastes and municipal sludge respectively. The methane production of the cow manure and food waste and the biogas production of the food waste decreased slightly.
