Industrial scale garage-type dry fermentation of municipal solid waste to biogas

The objectives of this study was to through monitoring the 1st industrial scale garage-type dry fermentation (GTDF) MSW biogas plant in Bin County, Harbin City, Heilongjiang Province, China, to investigate its anaerobic digestion (AD) performance and the stability of process. After a monitoring period of 180 days, the results showed that the volumetric biogas production of the digesters and percolate tank was 0.72 and 2.22 m(3) (m(3) d)(-1), respectively, and the specific biogas yield of the feedstock was about 270 m(3) CH4 t VS-1, which indicated that the GTDF is appropriate for the Chinese MSW. This paper also raised some problems aimed at improving the process stability and AD efficiency. (C) 2016 Published by Elsevier Ltd.
