Landfill areas have always been a common application for municipal solid waste management. However, land use problems, environmental pollution and increasing recycling implements have limited the amount of solid waste which is stored in the landfill areas. Despite all disadvantages, it is still considered a preferred disposal method fort he solid waste, especially when methane gas released from the areas is used to obtain electrical energy. In this context, the aim of this study is to estimate the landfill gas amounts originating from the Erzurum Solid Waste Landfill area using the LandGEM 3.02 version developed by EPA and to compare it with the methane gas concentrations measured on-site for the last three years. Total landfill gas, methane, carbon dioxide, and NMOC amounts were estimated with the model by choosing the basic parameters of the LandGEM (k and Lo values) according to the Clean Air Act and AP-42 inventory suggested by the EPA. The amount of the same gases was also predicted by manually calculated the k and Lo values (User Specified) with the specific data of the field. Finally, the amount of landfill gases obtained by using all three inventories (the Clean Air Act, AP-42 and User Specified) was compared with the methane concentrations measured in the field in order to confirm the model results. First result is that the methane gas concentrations predicted by the model were nearly close to the real methane measurements on site. Secondly, the operating period determined as 20 years for Erzurum landfill area when it was put into operation in 2008, while it was estimated as 23 years according to the LandGEM model results. Erzurum Solid Waste Landfill area has already been designed for power generation and the energy is produced at present. Therefore, the model can easily be used and verified for future improvement of the landfill area and the prediction of the amount of the energy obtained from the wastes.

“…Refs. [6,36,37] evaluated the economic viability of generating electricity from sanitary landfills and anaerobic reactors in the state of Minas Gerais. This study demonstrated that the state would benefit from the electrical energy generated: 15,400 MWh/year with an installed power capacity of 3200 kW generated by the OFUSW.…”

The elevated presence of organic material in Brazilian urban solid waste, along with mismanagement of its disposal, can aggravate environmental problems from greenhouse gas emissions to water and soil pollution. In parallel, the paper and cellulose industries consume considerable resources and produce important solid wastes, including lime mud. These urban and industrial realities present common ground, from which a little-studied alternative arises in using biogas electrical energy from the co-digestion of the organic portion of urban solid waste using lime mud. This intersection can reduce the environmental impacts associated with inadequate management and disposal of solid waste, providing industry financial economy resources and contributing to Brazilian energy grid diversification. The current study used economic–financial indicators to evaluate the proposal’s economic feasibility. The obtained results presented a minimum population of 165,200 inhabitants, generating 39,295.77 m3/year of methane, in order to enable a co-digestion proposal. The sensitivity analysis indicated that a population of 185,500 inhabitants would provide a 10-year payback, an energy rate of USD 0.139, and 44,124.49 m3/year of methane to supply the population with power. The net present value was USD 23,336.94, with an internal return rate of 14.71% and a levelized energy cost of 0.103 USD/kWh.

“…Atık yönetiminin amacı; atıkların çevre ve insan sağlığına zarar vermelerini engellemek, atıkların ülke ekonomisine kazanımını sağlamak, iş istihdamı oluşturmak ve sürdürülebilirliktir (Bilgili, 2020;Brito et al, 2021). En genel olarak tanımlanan atık yönetim piramidinde; önleme, azaltma, tekrar kullanım, geri dönüşüm, enerji geri kazanımı ve atıkların bertaraf edilmesi kademeleri bulunmaktadır (Andriani and Atmaja, 2019;Çevre ve Şehircilik Bakanlığı, 2022a;Tezel, 2020).…”

Günümüzde enerji kadar önemli bir diğer problem de gelişen teknolojinin, artan nüfus ve yaşam standartlarının en önemli sonucu olan artan atık miktarıdır. Kentlerde oluşan atıklar, şehrin nüfus yoğunluğuna ve bölgenin tüketim alışkanlıklarına bağlı olarak değişmektedir. İçerisinde sıvı ve gaz atıkların bulunmadığı kentsel katı atıkları düzenli depolama alanları kullanarak hem bertaraf etmek hem de enerji elde etmek mümkündür. Çünkü katı atıklar biyolojik olarak bozunmakta ve bozunma sonucunda ortama %45-60 oranında metan, %40-60 oranında karbondioksit gazı salmaktadır. Depo gazı olarak da tanımlanan bu gazın potansiyeli, ülke nüfusunun ortalama 84 milyon, kişi başı atık miktarının ortalama 1,13 kg olduğu göz önüne alınırsa ne kadar yüksek olduğu aşikardır. Bu nedenle tüketimin ana sebebi olan insanoğlu doğada var olduğu sürece, kentsel katı atıklar sürdürülebilir bir enerji kaynağıdır. Bu çalışmada; 2020 yılı TUİK verileri kullanılarak her geçen gün artan düzenli katı atık depolama alanlarımızdan elde edilebilecek depo gazının güncel enerji potansiyeli araştırılmış ve diğer enerji kaynakları ile karşılaştırılması yapılmıştır.
