Our technology

Flue Gas Cleaning

As our population increases, an energy deficit becomes increasingly problematic for many countries, but now that we are able to extract energy from mass amounts of waste, the only real issue remaining, is its effect on the environment. Waste composition is heterogeneous and leads to the formation of flue gases, which, if not cleaned properly, will cause significant air pollution. The ramifications would be detrimental if Steinmüller Babcock Environment continued these processes without taking into consideration the effects our activities have on the natural world.

We can proudly report that our effective flue gas cleaning systems, have kept the land surrounding our plants free of any toxic substances. Harmful matter such as dioxins, particulate matter, or heavy metals, remain absent from the emissions of our Waste to Energy processes. The regulations imposed on Germany and Europe in recent years have seen a great shift in the Waste to Energy operation. So much in fact, that the plants now produce cleaner emissions than the combustion air.

Maximum flexibility and leading technology

We never cease to strive for ways to ameliorate in accordance with environmental health. In fact, the use of our innovative technology, which was drawn from extensive research and experience in the field, allows us to combine a myriad of tech to meet and even exceed customer demand.

The area surrounding our plants are proven to be clean of any harmful substances – thanks to our innovative flue gas cleaning systems.

WE DEVELOP DESIGN SUPPORT BUILD A CLEANER FUTURE

One step further - Energy from flue gas

Given our track record in technological breakthroughs, we’ve taken the liberty of offering individual solutions to demanding customers, allowing for a combination of flue gas cleaning with energy recovery systems, such as condensation.

Providing such an array of innovations has been a journey of technical exploration, yet challenging all the same. Steinmüller Babcock Environment, offers just the right technology to our customers, providing access to excellent solutions with optimal energy output.
