Sewage sludge

Turning Sludge into Value Through Expertise

As landfilling and agricultural spreading of sewage sludge face increasing regulatory restrictions and co-incineration capacity in fossil fuel fired power plants is decreasing, incineration emerges as a sustainable and necessary solution for sewage sludge. LAB designs and delivers state-of-the-art, BAT flue gas cleaning systems that ensure full compliance with environmental standards while optimizing operational reliability and long-term performance.

With decades of experience in flue gas treatment, LAB offers tailored solutions for sewage sludge mono-incineration plants equipped with fluidized bed furnaces, rotary kilns, or grate furnaces. Our technologies are engineered to address the specific challenges posed by sewage sludge incineration, combining technical precision with environmental responsibility.

Meeting the Complex Challenges of Sludge Incineration

Sewage sludge is a complex waste stream containing heavy metals, nitrogen compounds, persistent organic pollutants and fine particulates besides comparable high amounts of Sulfur complexes. Its incineration generates flue gases that require advanced and multi-stage treatment to ensure compliance with strict emission limits for NOx, NH₃, SO₂, HCl, HF, heavy metals, dioxins and dust.

LAB’s flue gas cleaning systems are designed to efficiently remove these pollutantsat a very high efficiency by producing mostly gypsum. Each plant is engineered to match the specific needs of the combustion process and the local regulatory emission context, ensuring flexibility and optimal performance across a wide range of configurations.

Tailor-Made, High-Performance Systems

LAB covers the full spectrum of flue gas cleaning technologies; residue management and secure handling systems are also integrated into our turnkey solutions.

These systems are adaptable to new installations as well as retrofits, and are optimized for energy efficiency, low reagent consumption, and easy maintenance. The result is a fully compliant, future-ready facility that supports the circular economy and environmental commitments of operators.
