We incinerate for industry. And substitute primary fuels.
The abandonment of fossil fuels such as coal, oil and gas is a central component of sustainable environmental policy. Particularly in energy-intensive industrial processes environmentally friendly and economically viable alternatives to traditional primary fuels are needed. Unlike finite resources, waste represents a more or less inexhaustible supply with interesting energy potential and that’s why it is the specialist subject of EEW Energy from Waste (EEW). Alongside modern waste incineration plants, EEW develops, builds and runs power plants which operate on specially processed household, trade and industrial waste. These substitute fuels have a considerably higher energy value than ordinary household waste and serve large-scale industry in particular for the decentralised production of energy in the form of electricity, heating and process steam.
Scrupulous environmental stipulations
The burning of substitute fuels is subject to strict environmental conditions. Defined minimum temperatures of 850°C in the boiler ensure that any pollutants within the waste, such as dioxins and furans, are completely destroyed. Nitrogen oxides are converted by the addition of uric acid into environmentally neutral nitrogen and water. Multi-stage flue gas purification reduces dust, heavy metals and other pollutants to a minimum. The remaining slag is processed and re-used in road and landfill site construction, flue ash and filter dust is disposed of sustainably. This ensures that the secondary fuels provide energy without causing ecological harm.
Reduction of CO2 emissions
In the seven current refuse-driven fuel (RDF) plants which EEW operates independently or in conjunction with industry partners, a total of 1.4 to 1.5 tonnes per annum of secondary fuels are incinerated. By substituting fossil fuels the RDF plants of the corporate group are making a significant contribution to reducing environmentally-damaging CO2 emissions. Depending on the biogenetic make-up of the substitute fuels, up to a third less carbon dioxide is released in comparison to coal. Secondary fuels are therefore increasingly becoming the first choice.
