Sutco UK Selects Lindner Polaris 2800 and Komet 2800 Shredders

When designing a modern waste processing plant, selecting the right shredding technology can have a significant impact on throughput, output quality, energy consumption and long-term plant availability.

For a major UK project, Sutco RecyclingTechnik UK selected Lindner shredding technology exclusively, choosing a combination of Polaris 2800 one-step shredders and Komet 2800 secondary shredders.

The major contract included three Lindner Polaris 2800 shredders and two Komet 2800 universal shredders, demonstrating the flexibility of Lindner technology across different stages of waste processing.

The project also highlights an important principle in modern waste processing: the best shredding solution isn’t necessarily about choosing one machine. It is about selecting technology that works effectively within the complete processing system.

 

Sutco UK Chooses Lindner Shredding Technology

Sutco RecyclingTechnik is an established international plant builder specialising in waste processing and recycling systems.

The company has developed hundreds of references globally and operates subsidiaries in several countries, including the UK. Its approach is centred around providing efficient, integrated and turnkey recycling solutions.

For this major project, Sutco UK opted exclusively for Lindner technology.

The contract included:

• 3 × Lindner Polaris 2800
• 2 × Lindner Komet 2800

The machines were selected for different roles within the planned waste processing applications.

The Polaris 2800 would be used for one-step processing of pre-sorted waste, while the Komet 2800 machines would provide high-performance secondary shredding.

 

Why Choose the Lindner Polaris 2800?

The Lindner Polaris 2800 is a single-shaft industrial shredder developed specifically for high-throughput one-step processing.

It is particularly suited to applications where operators need to process untreated or pre-sorted municipal, commercial and industrial waste into a controlled fuel fraction.

For the Sutco project, the Polaris 2800 was specified to reduce pre-sorted waste to a particle size of less than 75 mm in a single operation.

This is one of the major advantages of one-step shredding.

Rather than requiring several size-reduction stages, suitable material can be processed directly to the required specification in one shredding stage.

This can potentially simplify the plant layout, reduce material handling and improve overall process efficiency.

 

What is One-Step Waste Shredding?

One-step shredding is a processing approach in which waste is reduced to the required output specification through a single shredding stage.

Traditionally, some waste processing systems use multiple shredders:

Primary shredder → Separation → Secondary shredder → Final output

A one-step system can simplify this process for suitable materials:

Waste → One-step shredder → Final output

The suitability of this approach depends on the incoming waste, required throughput and final particle-size specification.

The Polaris was developed specifically for this type of application.

The Lindner Polaris is a specialised single-shaft shredder for one-step processing of untreated municipal, industrial and commercial waste, including applications involving recovered fuels.

Why Was the Polaris 2800 Suitable for the Sutco Project?

Sutco identified several important requirements for the shredding equipment.

The machines needed to provide:

• High throughput
• Consistent output
• High availability
• Straightforward maintenance
• Reliable operation
• Controlled particle size

Machine continuity and availability were particularly important considerations for the project.

The Polaris 2800’s design was well suited to these requirements.

Its robust single-shaft configuration combines high torque with controlled material processing, while the machine is designed for continuous industrial operation.

Simple and Robust Design

One of the reasons Sutco selected the Polaris was its straightforward mechanical design.

The machine offers a combination of robust construction and easy maintenance, which are important considerations in a demanding waste processing environment.

This is particularly relevant when looking at the lifetime cost of an industrial shredder.

A machine’s purchase price is only one part of the investment.

Operators also need to consider:

• Maintenance requirements
• Wear component costs
• Energy consumption
• Availability
• Downtime
• Service support
• Spare parts availability
• Expected operating life

A machine that is easy to maintain and keeps production running can deliver significant value over its lifetime.

The Lindner Komet 2800

While the Polaris was selected for one-step processing, Sutco also chose the Lindner Komet 2800 for secondary shredding applications.

The Komet is designed for high-performance secondary shredding where controlled size reduction and consistent output are required.

It is particularly relevant to applications such as:

• SRF production
• RDF production
• Commercial waste processing
• Industrial waste processing
• Municipal waste
• Pre-shredded waste
• Alternative fuel production

The Komet range provides high-performance secondary shredding technology designed for precision size reduction and high-quality SRF production.

Polaris vs Komet: What’s the Difference?

Although both machines are Lindner shredders, they perform different roles within a waste processing system.

Lindner Polaris
The Polaris is designed for one-step shredding.

It can take suitable untreated or pre-sorted waste and produce a defined output in a single processing stage.

Typical applications include:

• RDF production
• SRF production
• Alternative fuel processing
• One-step waste shredding

Lindner Komet
The Komet is designed primarily for secondary shredding.

It is used when material has already undergone initial processing and requires further size reduction and refinement.

Typical applications include:

• SRF production
• RDF production
• Secondary waste shredding
• Fine or controlled size reduction

The correct machine therefore depends on the material, process configuration and required final specification.

Why Availability Matters in Waste Processing

Waste processing plants often operate continuously, meaning equipment availability can directly affect production output.

A shredder that stops unexpectedly can create a knock-on effect throughout the plant.

A breakdown can result in:

• Lost production
• Idle labour
• Disrupted sorting
• Delayed deliveries
• Reduced plant utilisation
• Additional maintenance costs

This is why machine continuity and availability are critical considerations when selecting shredding equipment for a major processing project.

The Polaris was particularly attractive because of its robust design and uncomplicated maintenance requirements.

Maintenance and Service Support

Industrial shredders operate in some of the harshest processing environments.

Wear components are inevitably subjected to significant loads, making preventative maintenance and access to replacement parts an important part of machine ownership.

For high-throughput processing facilities, access to technical assistance and replacement parts can make a significant difference to overall plant availability.

A reliable shredder is important, but so is having the right support behind it.

The Importance of Choosing the Right Shredder Partner

A successful shredding installation involves more than selecting a machine.

The wider support package should also be considered.

Application knowledge
Understanding the material and process requirements before recommending a machine.

Installation
Ensuring the shredder is correctly integrated into the processing system.

Commissioning
Making sure the equipment performs as expected once operational.

Maintenance
Keeping the machine running reliably throughout its operating life.

Spare parts
Ensuring critical wear and replacement components are available when needed.

Engineering support
Providing technical expertise when the plant encounters an unexpected problem.

This is particularly important for large waste processing installations where a single equipment failure can affect the entire production line.

Rather than simply selecting a shredder based on machine size.

Choosing Between One-Step and Two-Stage Shredding

One of the most important decisions when developing an RDF or SRF processing system is whether to use a one-step or multi-stage shredding process.

One-step processing
A machine such as the Polaris can provide a defined output in a single shredding stage.

Potential advantages include:

• Simplified plant configuration
• Reduced material handling
• Fewer processing stages
• Potentially lower footprint
• Straightforward operation
• High throughput

Two-stage processing
A combination of primary and secondary shredders can provide greater control over the material throughout the process.

This can be advantageous where:

• Incoming material is particularly difficult
• Significant separation is required
• A precise final particle size is needed
• The process requires staged size reduction
• Different materials need to be treated at different stages

Neither approach is universally better.

The correct choice depends on the material and the required output.

A Major Lindner Shredding Installation

The Sutco UK project demonstrates how different Lindner shredding technologies can be combined across a large-scale waste processing operation.

The selection of three Polaris 2800 shredders and two Komet 2800 shredders provided Sutco with dedicated equipment for both one-step and secondary shredding applications.

It also demonstrates why machine reliability, maintenance and technical support are critical factors when selecting industrial shredding equipment.

For high-throughput waste processing, the shredder needs to do more than simply reduce material in size.

It needs to perform consistently, remain available and integrate effectively with the wider processing system.
