Transforming waste into energy with EING

EING’s refuse-derived fuel (RDF) solutions from ANDRITZ are setting new standards for waste-to-energy processes.

Refuse-Derived Fuel (RDF) is a crucial substitute for primary materials such as gas, oil and coal. The composition of RDF - primarily combustible fractions like plastics, paper, and biomass - ensures that it can replace primary materials while contributing to a circular economy.

The ANDRITZ ADuro S shredder at EING reduces RDF material down to 20 millimeters.

Using ANDRITZ custom waste-to-energy solutions, RDF can be produced in high, medium and low calorific types to suit specific firing technologies. Waste processing serves the dual function of sorting and recycling materials from waste streams which include household, industrial, and bulky waste, as well as production residues. These inputs are processed to yield plastics, textiles, paper, and both ferrous and non-ferrous fractions, which are then refined to meet stringent standards for calorific value, moisture content, and particle size distribution.

The potential is clear, but it is demanding to process large volumes of mixed waste into consistent fuel quality, particularly with industry’s high expectations for throughput and efficiency. With expertise from ANDRITZ however, EING’s operation in Germany’s North Rhine-Westphalia has risen to the challenge, and it produces high-quality RDF for cement and power plants.

“By replacing two older machines with a single unit featuring a 2.4-meter* cutting length, EING has streamlined ist operations without sacrificing capacity.“

*Up to 3.2-meters cutting length is available

Pivotal role of ADuro S Secondary Shredder

EING has more than 30 years of experience in recycling post-consumer packaging. Following a technical upgrade at its plant in Gescher, an ADuro S-2400 secondary shredder from ANDRITZ is now at the heart of its process. Easy to run, operate and maintain, this machine delivers an impressive average hourly throughput of 10 tons, reducing RDF material down to 20 millimeters, which is ideal for the cement industry.
The investment has provided a significant boost to EING’s efficiency: “By replacing two older machines with a single unit featuring a 2.4-meter* cutting length, EING has streamlined its operations without sacrificing capacity,” says Bernhard Schachinger, Head of Product Management, ANDRITZ Recycling.

The technology has certainly had the opportunity to prove itself at EING, as Torben Vollmer, Product Manager, EING explains: “The ADuro S has already achieved more than 10,000 operating hours, consistently delivering reliable output quality and stable performance.”
The ADuro S represents the next generation in secondary shredding (the ADuro P is ANDRITZ’s technology for shredding primary materials). Designed for use with RDF, municipal solid waste (MSW), solid recovered fuels (SRF), plastics, and both commercial and industrial waste, it is durable and flexible while minimizing energy consumption.

Unique features and benefits of the ADuro S include:

Intelligent pusher control system: Detects pressure, rotation speed, and power consumption, continuously adjusting the pusher pressure to ensure high throughput.
Cutting performance: With large cutting width up to 3.2 meters. High throughput and continuous cutting (combined with low energy consumption) are suitable for extreme applications.
Easy knife gap adjustment: Without opening the machine.
Special rotor design: Prevents ropes from wrapping. The modular rotor system is tailored to input material and throughput requirements. The knife-holder exchange system reduces downtime.
Quickly exchangeable screens: Allow many different output sizes. Tailored screen sizes are available for specific applications. They are also very light due to weld-free construction.
Water-filled cooling system: This is applied to the inner part of the rotor and prevents plastics from sticking during shredding.
Finely-shredded RDF: Ideal for the cement industry.

Operational Safety and Maintenance

Safety and efficiency are at the heart of EING’s operations, so it is particularly welcome that the reject and service hatches of its ANDRITZ shredders are designed to facilitate safe and efficient maintenance. Further features such as programmed pre-settings for various materials, protection clutches to avoid motor damage during overload, automatic safety lockout, and well-positioned service doors contribute to safety, ease of operation and maintenance.

Partnership and Service Excellence

“Every new project brings unique challenges, but the partnership between EING and ANDRITZ is built on trust, expertise, and a commitment to long-term success,”

Hendrik Thomas Iraschko
Plant Manager at EING

Service is a core part of all ANDRITZ customer relationships, and ANDRITZ’s service team is always on site at EING when needed, ensuring quick and effective solutions to any routine matters or challenges which arise. From installation to optimization and long-term support, ANDRITZ’s goal is to keep every machine running at its best.

“At EING, we are always on site when needed - whether for commissioning, fine-tuning, or preventive maintenance. That close cooperation makes a real difference,”

Michael Grossschädl
Director Global After Sales at ANDRITZ

EING’s journey, powered by ANDRITZ’s advanced technologies and service commitment, shows what can be achieved through the right combination of innovation, expertise, and collaboration.

“The EING project stands as a testament to the power of technology service and true partnership. The ADuro S represents the strength and quality of the entire ANDRITZ product portfolio - reliable, efficient, and tailored to our customers’ needs. We are proud of the results and of what we have accomplished together with EING.”
