Pollutant Decrease

Thanks to the latest filtering and firing technology, waste incineration plants fulfil higher environmental standards than other industrial plants. The amendment of the 17th Directive of Germany`s Federal Immission Control Act (17th BImSchV) resulted in the definition of the most stringent emission limit values worldwide as well as strict emission monitoring requirements.This has made waste incineration plants the most stringently regulated industrial plants in Germany. These Europe-wide standards are exemplary.

Climate Protection

In the past, biological and chemical processes involving the biogenic proportion of residual waste on refuse dumps gave rise to climate-damaging emissions such as carbon dioxide and methane. These emissions contributed significantly to development of the greenhouse effect. A total of 1.5 million metric tons of methane were emitted from German landfills in 1990. Methane is 21 times more climate-damaging than carbon dioxide. Emissions were reduced to 0.5 million metric tons by 2004 thanks to a combination of factors, including reduction of waste dump capacities, utilisation of the emitted landfill gas and increased waste recycling in incineration plants.

Flue Gas Cleaning

The combustion of waste results in the production of a mixture of gases containing pollutants such as carbon dioxide, sulphur dioxide, dust and soot, as well as nitrogen oxides, heavy metal bearing fumes and unburned hydrocarbons. The pollutants can be removed from the flue gases by using the latest flue gas cleaning systems, so that harmful organic and inorganic substances are no longer discharged into the atmosphere. These substances are partly incorporated in the reaction-neutral slag or concentrated in the filter dust as end product of the flue gas cleaning process, allowing them to be deposited safely underground. Pollutants are therefore continuously removed from the environmental cycle - pollutants that were formerly emitted to the environment from waste dumps.

Emissions.

Emission (lit. sending out) is the term used to describe the discharge of pollutants to the air, ground and water. In order to reduce environmental pollution by emissions, stringent limits have been prescribed in the Technical Instructions on Air Quality Control (TA Luft) by the German Federal Immission Control Act (BImSchG). This represents a significant environmental protection objective. Maximum limitation of environmental pollution as a result of incineration and co-incineration of waste throughout Europe, is the aim of the new guideline 2000/76/EC. The guideline specifically defines certain operating conditions, special technical equipment requirements and emission limits.

Residual Materials

Only 10 percent residues remain after the incineration. Most of this is made up of the slag produced by the combustion process. Molten metals are extracted from the slag and reused. Another product obtained is boiler and filter dust from the flue gas cleaning process.
