The air pollution controls required in incineration plants are extremely expensive. Very often up to one half of the costs of a plant are due to air pollution control facilities. As the laws can change and maybe require updates in the air pollution controls this could lead to much higher costs in the future.
Energy, produced by means of waste incineration is not likely to be practical for small communities. Therefore incineration plants have be situated in areas where the district heating network can easily be connected to very many households.
The extremely high technical standards of the plants require skilled workers, which leads to the facts that rather high wages have to be paid.
