Evaluation of technical and economic applicability of rehabilitation of municipal solid waste storage areas and energy generation from warehouse gas

Despite being non-suitable within environmental parameters, uncontrolled disposal sites are stil being used as a part of the solid waste management and many of these sites in many places are waiting to be fixed, as the implementation of sanitary landfills are fairly new. Uncontrolled disposal sites are fields, which require serious funding and have major potential, as they are a means to produce energy. Therefore, the question of whether the producing energy from the stored gas could cover the expenses of the rehabilitation facility is an important one for a newly closed uncontrolled disposal site. Within this context, a sample uncontrolled disposal sight was selected and the rehabilitation process and technical and economical feasibility of its energy production was monitored. Rehabilitation and energy production system of the sample field's initial set up expenses and the income from it's elecricity production were calculated. In order to examine the economical feasibility, LandGEM model was used when estimating the prospective storage gas and potential energy production levels were calculated. According to the findings of the study, while the yearly average of energy production of the sample field was 0,897 MW in 2018, approximate prediction of energy production was valued as 0,823 MW in the same year. Having considered the fact that the field will be operated for 15 years, it was discovered that the profits will be 3,18 million $ within the context of cost-analysis findings. In conclusion of the study, it was realised that the rehabilitation process for the uncontrolled disposal sites was feasible in technical and economical terms, yet, it's profit margin was determined as low yield.
