Abstract Municipal solid waste (MSW) landfills now represent one of the most important issues related to the waste management cycle. Knowledge of biogas production is a key aspect for the proper exploitation of this energy source, even in the post-closure period. In the present study, a simple mathematical model was proposed for the simulation of biogas production. The model is based on first-order biodegradation kinetics and also takes into account the temperature variation in time and depth as well as landfill settlement. The model was applied to an operating landfill located in Sicily, in Italy, and the first results obtained are promising. Indeed, the results showed a good fit between measured and simulated data. Based on these promising results, the model can also be considered a useful tool for landfill operators for a reliable estimate of the duration of the post-closure period.

The problem of the formation of unauthorized municipal solid waste landfills is very urgent in the world. Municipal solid waste landfills affect the state of ecosystem assets of territorial communities and, accordingly, the flow of ecosystem services. The economic assessment of qualitative and quantitative changes of ecosystem services as a result of the negative impact of unauthorized landfills is a basic element of an effective policy in the field of municipal solid waste management. One of the ecosystem services, the assessment of which is given a lot of attention in the scientific literature is the hydrological regulation ecosystem service. The aim of the research is the economic assessment of changes in hydrological regulation ecosystem service from the negative impact of unauthorized municipal solid waste landfills. In the scientific literature, the economic assessment of hydrological regulation ecosystem service is considered as a function of the increase in the river or underground runoff and the cost of water. It is proposed to calculate the economic assessment of changes in hydrological regulation ecosystem service from the negative impact of unauthorized municipal solid waste landfills as a function of: the magnitude of the change in groundwater flow in the summer from the negative impact of unauthorized municipal solid waste landfill; tax rates for water abstraction from an underground source; landfill area; the coefficient of changes in the structure of the ecosystem within the landfill (destruction of vegetation cover); the area of impact of the landfill (outside the landfill) on the ecosystem; coefficient of change in the area of impact of the landfill. Changes in the hydrological regulation ecosystem service from the negative impact of unauthorized municipal solid waste landfills on the territory of the Korostyshevskaya territorial community of the Zhytomyr region have calculated. The main problems of assessing changes in hydrological regulation ecosystem service from the negative impact of unauthorized municipal solid waste landfills are identified: obtaining reliable and complete factual information about changes in underground runoff and the characteristics of the ecosystem from the negative impact of unauthorized municipal solid waste landfills within the landfill and the zone of its influence. Due to the insignificant value of the cost of changing the hydrological regulation ecosystem service, it was concluded that it is inexpedient to take it into account when making managerial decisions about small and low-power unauthorized municipal solid waste landfills.
