Waste to Energy (WtE)

Previously the only option for disposal of domestic and municipal waste was through landfill sites. This was costly to local councils and companies in terms of landfill taxes, and was not sustainable indefinitely due to the availability of suitable sites. Through the development of incineration and energy technology, a new alternative is available which converts such waste materials into power. Waste-to-Energy Facilities (WtE) provide a solution to many waste management problems and also contributes to our desire for sources of Renewable Energy.

During the incineration process ash residue, acidic gases, dioxins and heavy metals are generated within the waste gas, for which emissions to the atmosphere must be reduced to meet legal air quality standards. In Australia, air quality standards are set by the National Environment Protection Council (NEPC); however monitoring and enforcement is carried out by State/Territory agencies.

Luehr Filter provides Air Pollution Control Technology to reduce emissions from WtE plants well below those set by the NEPC.  Through our custom designed dry absorption processes, using a range of additives (such as Activated Carbon, Ca(OH)2, CaCO3, Na2CO3, NaHCO3 etc.) and specialised gas conditioning equipment, we reduce waste gas temperatures to the ideal levels for chemical reaction with absorption reagents. Patented equipment such as the Luehr Conditioning Rotor, ensure ideal reaction conditions with the additives. Additionally the Luehr KUV additive recirculation system ensures fully efficient use of additive material, significantly reducing plant operating costs. The specialised range of Luehr Flat Bag Filters ensures the collection of ash residue and spent additive, prior to the treated gases being released to atmosphere.

Luehr Filter has accumulated a wealth of experience on many successful plant installations within the WtE industry across the UK, Europe and the United States.
