At this study, modern composting and anaerobic digestion applications in Adana Metropolitan Municipality was investigated. Adana is the 6th crowded city in Turkey. The disposal plant receives approximately 2.2 million people’s waste in Adana. The daily amount of household waste is estimated at 1800 ton/day. Before 2008, Adana had wild landfill area. Adana Integrated Solid Waste Disposal Plant’s construction was started in December 2008 and finished the beginning of 2011. This plant’s components are; recreation the wild and using of sanitary landfill areas, producing energy from biogas via the anaerobic fermentation system and within landfill area collected by horizontal and vertical piping systems, sorting plant, medical waste sterilization and composting unit. At the first step; household waste is separated at the sorting plant. Thus organic, paper, plastic, glass, metal etc. waste is sorted. After that, organic waste is decomposed by microorganisms with the anaerobic digestion system. Thus methane gas and wet compost is occured by the anaerobic fermentation reaction. There is also methane gas is collected at the dumping area through vertical and horizontal piping system. There are units of gas engine for converting methane gas to electricity. Total gas engine production capacity is 15.4 MWh. By this process, methane gas is burnt and it is produced to generate approximately 11 MWh electricity power. Adana Integrated Solid Waste Disposal Plant’s proces datas and applications were investigated, thus a modern biological treatment approach provided with this work. The electricity production capacity of the process is 71%. The aim of this study is to develop and determine the optimum parameters of electricity and compost production capacity.
