Landfill gas (LFG) utilization was used for many years around the world, especially in US and Western Europe. But in Ukraine this practice was implemented only few years ago due to the lack of technologies, equipments and poor organization of municipal solid wastes deposition. The Gas Institute of NAS of Ukraine was among the first institutions who are involved in the technology development which will adapt to local the conditions. The first system for the collection and disposal of LFG using modern methods of calculating, techniques and materials was developed, which included the utilization of 600-800 m3/hr LFG to generate of an approximately 1 MW of electricity. Due to the original technical solutions, we were allowed to develop this system at the operational landfill. Mathematical modeling of the system was carried out with the software system GasCondOil. The calculations obtain the basic characteristics of the system: The material balance of LFG in the system, the pressure difference (input-output) in all sections of pipelines, the gas flow rate, phase composition and the flow. The system was analyzed for the absence of out-of-range parameters. A technological development has been successfully implemented in the year 2012 at the landfill by LNK Company, and is one of the leading companies in the field of LFG utilization in Ukraine. A station for LFG processing into electricity was created as the first stage of the complex design, to produce 4.5 MW of electricity. Now we have implemented the technology at five landfills of Ukraine with total electrical power 6.2 MW. Today produced electricity has rise the point to 60 million kWh. Hence, this development allows the reduction in methane pollution by 300,000 MT CO2eqv.
