ANDRITZ starts up sludge drying plant at Eldorado Brasil Celulose
2025/12/12
International technology group ANDRITZ, which supplied the technology and developed the new biological sludge drying plant for Eldorado Brasil Celulose’s pulp mill in Três Lagoas, Brazil, celebrated the plant’s successful start of operations.
This project represents another step forward in Eldorado’s strategies to transform waste into energy and enhance the environmental efficiency of its operations.
With the capacity to process up to 22 tons of dry solids per day, the plant was designed to dry the biological sludge generated from the industrial wastewater treatment process. After drying, the material is used as fuel in the mill’s power boiler, significantly reducing the volume of waste sent to landfills, benefiting the environment, and delivering substantial energy gains.
ANDRITZ’s scope of supply included sludge dewatering centrifuges, an aspiration air system, the complete drying process, dry product handling, exhaust gas condensation, as well as automatic and manual valves, instrumentation, steel structures, and platforms. ANDRITZ was also responsible for the basic and detailed engineering, along with technical support during installation, commissioning, and start-up.
At the heart of the plant is the ANDRITZ Gouda paddle dryer, type 17W300 – the largest model in the ANDRITZ portfolio. With its robust design and advanced technology, it ensures efficient drying with high operational safety, easy operation, and minimal maintenance requirements.
“The successful start-up of this plant underscores ANDRITZ’s commitment to delivering high-performance technical solutions that meet the most demanding environmental standards. We are proud to support Eldorado in its journey toward more sustainable and efficient operations,” says Luiz Paulo, Senior Technical and Commercial Manager at ANDRITZ.
With this project, ANDRITZ further strengthens its position as a strategic partner offering complete, customized solutions for the pulp and paper industry. ANDRITZ has been the key supplier for Eldorado Brasil’s pulp mill.
