For this purpose, a dry anaerobic digester (100 L) with percolate tank (200 L) was designed at pilot scale. Municipal solid wastes were fed into the dry fermentation unit and system was operated with intermittent recycling of leachate through percolation unit back to the dry fermentation unit twice a day. Gas production in both unit was recorded daily and gas content and leachate analysis were carried out periodically. A batch feeding of solid waste (17.5 kg waste) having less than 5 cm particle size with a dry matter of 13% and organic dry matter of  85%  was carried out and process was operated for 60 days. Results indicated that 560 L methane per kg organic dry matter was produced. This corresponds to biogas production 119 m 3 per ton of wet solid waste. It was also observed that the main gas production took place in percolate tank and the solid digester acted as a hydrolysis and acid reactor indicated by the low gas production and acidic leachate characteristics. There were also almost no digestate generation which eliminates costly post treatment units before the discharge of digestate, which is a critical problem for wet digestion counterpart.  <o:p> </o:p> }, number={1}
