Turning Waste into Energy – A Sustainable Success
Client: Ignis Bio Energy
Delivered by: AMOF Fjell Process Technology AS
Application: Sludge Dewatering, Drying & Energy Recovery
Industry: Renewable Energy & Aquaculture
Location: Norway
Project Overview
AMOF Fjell Process Technology AS is proud to showcase the successful delivery and commissioning of an advanced sludge dewatering and drying system for Ignis Bio Energy. This project is a strong example of how sustainable thinking and smart process design can turn waste into a valuable resource.
The Solution
At the core of the system is our Disc Dryer AF-TD-170+, a robust and energy-efficient dryer designed to handle challenging sludge materials with high reliability and low energy consumption.
The full process includes:
- Mechanical Dewatering: Sludge is first pressed to remove free water.
- Thermal Drying: The disc dryer then dries the sludge to a dry matter content of 90–95%.
- Energy Recovery: Energy from incineration of the dried sludge, and waste heat from the drying process where dryer vapors is recovered to improve system efficiency.
Successful Commissioning
A major milestone has now been reached: Ignis Bio Energy is successfully running their furnace on dried sludge for the first time. This marks the transition from startup phase to full operation—and proof of concept that sludge can serve as a sustainable energy source.
Circular Economy in Action
What makes this project truly innovative is its integration into a circular value chain. The energy generated from sludge combustion is used not only to dry more sludge but also to heat fish tanks at Gaia Salmon’s aquaculture facility.
This closed-loop system significantly:
- Reduces waste
- Improves energy efficiency
- Supports renewable energy production
- Strengthens the link between waste management and food production
Our Contribution
AMOF Fjell supplied a complete system including:
- Sludge press
- Disc dryer with heat recovery
- Control system
- Commissioning and startup support
Our team has worked closely with Ignis Bio Energy throughout the project to ensure a smooth transition from delivery to successful operation.
Conclusion
This project is a perfect example of our mission: to deliver smart, sustainable, and efficient process solutions. We congratulate Ignis Bio Energy on their innovation and successful startup, and we are proud to be part of a project that brings real environmental and economic benefits.
