Air pollution control technologies for energy-from-waste plants

The global economy is in constant need of power, which is still mainly provided by coal, oil and gas – fossil fuels that are finite and harmful to the environment over their whole value chain. Other more sustainable resources such as municipal waste or sludge have started to establish their position in the industry and are gaining more attention now due to the global effort to develop and install solutions that will minimize CO2 emissions.

ANDRITZ as a supplier of state-of-the-art flue gas cleaning systems is the professional and reliable partner with close to 40 years of experience in flue gas cleaning business with numerous references around the globe.

Safe waste treatment and climate-friendly energy: air pollution control processes developed in-house remove all pollutants in an efficient, sustainable and reliable way. Customized concepts enable us to guarantee emission levels that fall below those of the world’s toughest pollution control standards.

Thermal treatment is not only the smartest way of dealing with non-recyclable waste, it also makes the most economical use of resources and is the most environmentally friendly technology. Recovery of the energy contained in waste makes it a key part of an integrated energy and environmental policy concept.

Clean Air Technologies for various industries

After steps have been taken towards avoidance and recycling of waste, thermal treatment is a final indispensable stage in modern, sustainable waste management. It offers maximum reduction of all pollutants and cuts waste volume by more than 90%.

The waste-to-energy approach makes it possible to save crucial fossil fuel resources such as coal, oil and gas. What is more, since 60% of the energy in waste comes from renewable sources, the largest part of the cycle is CO2-neutral. Emissions from waste-to-energy plants are as much as a factor of four below those from conventional power plants. Waste-to-energy is safe, economical, and it helps to protect our environment and natural resources.
