The rise in living standards, modernization and the increasing purchasing power of the population create more and more waste. It is important to continuously and adequately dispose the waste of, because its depositing in landfills is becoming increasingly risky and economically unsustainable. Large piles of waste are dumped in the immediate vicinity of settlements and cities, which has an extremely unfavorable effect on people's health and the quality of life in those areas. The problem of waste is not only its disposal, but also a number of factors such as collection and removal of waste, evaluation and reuse. Today, various methods of waste treatment and recovery such as recycling and disposal are being developed in order to reduce the pressure on the already overcrowded landfills. Waste can be used in different ways for example we have sorting and recycling at the source or incineration. Energy obtained from waste represents an effective solution that would simultaneously solve large amounts of waste in landfills and the need for conventional energy sources. The process of municipal solid waste processing, called mechanical-biological processing (MBO), has as its basic task the reduction of potential of the waste that needs to be disposed of. Waste from households, waste that we receive in different sectors, and which in its composition and properties are similar to waste from households and waste that is created by taking care of public areas, we call municipal solid waste.
