A unique engineering project has raised the bar for efficient energy capture from incineration of garbage and provided a sports facility in an urban location
Efficiency edge Amager Bakke will recover resources that otherwise would not be recycled. More than 90% of the metal in the bottom ash will be filtered out, leaving a product for use by the construction industry that easily meets strict requirements for heavy metal content and leaching behaviour. Total true recycling will exceed 50%.The facility will also produce much more clean water than it uses through energy recovery using a two-step, flue-gas condensation system, which includes a heat pump. The water recovered will be as clean as distilled water. The flue gas condensation raises energy recovery around 20% — and that 20% gives Amager Bakke the edge. In warm weather when there is little demand for heating, the plant can also increase its electricity generation without having to raise its heat output. The ability to ramp electricity production separately from heat supply adds useful flexibility to a national power system increasingly reliant on variable supplies of electricity from wind power.
