The Confederation of Europe Waste-to-Energy Plants (CEWEP) represent about 380 Waste-to-Energy (WtE) plants across Europe, 88% of the European market. They thermally treat household and similar waste that remains (after waste prevention, reuse, and recycling), by generating energy from it. This is how they replace fossil fuels, such as coal, used by conventional power plants.Sophisticated filtering devices minimise the emissions into the atmosphere by blocking the pollutants originating from the waste, such as heavy metals. The Waste Incineration Directive 2000/76/EC introduced the most stringent emission limit values applied to any single industry in Europe. As an example, in 1990 one-third of all dioxin emissions in Germany came from waste incineration plants. For the year 2000 the figure was less than one (1%) percent, while the amount of waste thermally treated had more than doubled. The WtE plant (MVR) in Hamburg, Germany, operates one of the Best Available WtE Techniques.
